They are not intended to convey any specific Implementation or methodology requirements. 375 376 377 The term “repository item” is used to refer to an object (e.g., an XML document or a DTD) that resides in a repository for storage and safekeeping. Each repository item is described by a RegistryObject instance. The RegistryObject catalogs the RepositoryItem with metadata. 378 379 380 381 382 The term "RegistryEntry" is used to refer to an object that provides metadata about a repository item. The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, when they appear in this document, are to be interpreted as described in RFC 2119 [Bra97]. 383 384 Software practitioners MAY use this document in combination with other ebXML specification documents when creating ebXML compliant software. 385 3.3 Audience 386 387 388 The target audience for this specification is the community of software developers who are: Implementers of ebXML Registry Services Implementers of ebXML Registry Clients 389 Related Documents 390 391 392 393 394 The following specifications provide some background and related information to the reader: a) ebXML Registry Information Model [ebRIM] b) ebXML Message Service Specification [ebMS] c) ebXML Business Process Specification Schema [ebBPSS] d) ebXML Collaboration-Protocol Profile and Agreement Specification [ebCPP] Copyright © OASIS, 2002.

Later versions of the document will include additional capability as deemed appropriate by the OASIS/ebXML Registry Technical Committee. It is assumed that: 406 407 408 409 410 411 412 Interoperability requirements dictate that at least one of the normative interfaces as referenced in this specification must be supported. 1. All access to the Registry content is exposed via the interfaces defined for the Registry Services. 2. The Registry makes use of a Repository for storing and retrieving persistent information required by the Registry Services. This is an implementation detail that will not be discussed further in this specification. Copyright © OASIS, 2002. All Rights Reserved Page 15 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 413 5 System Overview 414 5.1 What The ebXML Registry Does 415 416 417 418 The ebXML Registry provides a set of services that enable sharing of information between interested parties for the purpose of enabling business process integration between such parties based on the ebXML specifications. The shared information is maintained as objects in a repository and managed by the ebXML Registry Services defined in this document. 419 5.2 How The ebXML Registry Works 420 421 422 This section describes at a high level some use cases illustrating how Registry clients may make use of Registry Services to conduct B2B exchanges. It is meant to be illustrative and not prescriptive. 423 424 425 426 427 428 The following scenario provides a high level textual example of those use cases in terms of interaction between Registry clients and the Registry. It is not a complete listing of the use cases that could be envisioned. It assumes for purposes of example, a buyer and a seller who wish to conduct B2B exchanges using the RosettaNet PIP3A4 Purchase Order business protocol. It is assumed that both buyer and seller use the same Registry service provided by a third party. Note that the architecture supports other possibilities (e.g. each party uses its own private Registry). 429 5.2.1 Schema Documents Are Submitted 430 431 432 A third party such as an industry consortium or standards group submits the necessary schema documents required by the RosettaNet PIP3A4 Purchase Order business protocol with the Registry using the LifeCycleManager service of the Registry described in Section 7.3. 433 5.2.2 Business Process Documents Are Submitted 434 435 436 A third party, such as an industry consortium or standards group, submits the necessary business process documents required by the RosettaNet PIP3A4 Purchase Order business protocol with the Registry using the LifeCycleManager service of the Registry described in Section 7.3. 437 5.2.3 Seller’s Collaboration Protocol Profile Is Submitted 438 439 440 441 The seller publishes its Collaboration Protocol Profile or CPP as defined by [ebCPP] to the Registry. The CPP describes the seller, the role it plays, the services it offers and the technical details on how those services may be accessed. The seller classifies their Collaboration Protocol Profile using the Registry’s flexible Classification capabilities. 442 5.2.4 Buyer Discovers The Seller 443 444 445 446 The buyer browses the Registry using Classification schemes defined within the Registry using a Registry Browser GUI tool to discover a suitable seller. For example the buyer may look for all parties that are in the Automotive Industry, play a seller role, support the RosettaNet PIP3A4 process and sell Car Stereos. 447 The buyer discovers the seller’s CPP and decides to engage in a partnership with the seller. Copyright © OASIS, 2002. All Rights Reserved Page 16 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 448 5.2.5 CPA Is Established 449 450 451 452 453 454 The buyer unilaterally creates a Collaboration Protocol Agreement or CPA as defined by [ebCPP] with the seller using the seller’s CPP and their own CPP as input. The buyer proposes a trading relationship to the seller using the unilateral CPA. The seller accepts the proposed CPA and the trading relationship is established. Once the seller accepts the CPA, the parties may begin to conduct B2B transactions as defined by [ebMS]. 455 5.3 Registry Users 456 457 458 We describe the actors who use the registry below. Some of the actors are defined in Section 12.7. Note that the same entity may represent different actors. For example, a Registration Authority and Registry Administrator may have the same identity. Table 1: Registry Users 459 Actor Function ISO/IEC 11179 Comments RegistrationAuthority Hosts the RegistryObjects Registry Administrator Evaluates and enforces registry security policy. Facilitates definition of the registry security policy. MAY have the same identity as Registration Authority Registered User Has a contract with the Registration Authority and MUST be authenticated by Registration Authority. The contract could be a ebXML CPA or some other form of contract. Registry Guest Has no contract with Registration Authority. Does not have to be authenticated for Registry access. Cannot change contents of the Registry (MAY be permitted to read some RegistryObjects.) A Registered User who does lifecycle operations on permitted RegistryObjects. A Registered User who has only read access Creates Registry Objects Note that a Registry Guest is not a Registry Reader. Submitting Organization Registry Reader Responsible Organization Copyright © OASIS, 2002. All Rights Reserved Registration Authority (RA) Submitting Organization (SO) Responsible Organization (RO) RO MAY have the same identity as SO Page 17 of 167 OASIS/ebXML Registry Services Specification v2.0 Registry Client March 2016 Registered User or Registered Guest 460 461 Figure 1: Actor Relationships 462 463 Note: In the current version of the specification the following are true. 464 A Submitting Organization and a Responsible Organization are the same. 465 Registration of a user happens out-of-band, i.e, by means not specified in this specification. 466 A Registry Administrator and Registration Authority are the same. 467 5.4 Where the Registry Services May Be Implemented 468 469 The Registry Services may be implemented in several ways including, as a public web site, as a private web site, hosted by an ASP or hosted by a VPN provider. 470 5.5 Implementation Conformance 471 472 473 474 475 476 477 An implementation is a conforming ebXML Registry if the implementation meets the conditions in Section 5.5.1. An implementation is a conforming ebXML Registry Client if the implementation meets the conditions in Section 5.5.2. An implementation is a conforming ebXML Registry and a conforming ebXML Registry Client if the implementation conforms to the conditions of Section 5.5.1 and Section 5.5.2.

All Rights Reserved Page 19 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 493 6 ebXML Registry Architecture 494 495 496 The ebXML Registry architecture consists of an ebXML Registry Service and ebXML Registry Clients. The ebXML Registry Service provides the methods for managing a repository. An ebXML Registry Client is an application used to access the Registry. 497 498 Figure 2: ebXML Registry Service Architecture 499 6.1 Registry Service Described 500 501 502 503 504 505 506 The ebXML Registry Service is comprised of a robust set of interfaces designed to fundamentally manage the objects and inquiries associated with the ebXML Registry. The two primary interfaces for the Registry Service consist of: A Lifecycle Management interface that provides a collection of methods for managing objects within the Registry. A Query Management Interface that controls the discovery and retrieval of information from the Registry. 507 508 509 A registry client program utilizes the services of the registry by invoking methods on one of the above interfaces defined by the Registry Service. This specification defines the interfaces exposed by the Registry Service as well as the interface for the Registry Client. Copyright © OASIS, 2002. All Rights Reserved Page 20 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 510 6.2 Abstract Registry Service 511 The architecture defines the ebXML Registry as an abstract registry service that is defined as: 512 1. A set of interfaces that must be supported by the registry. 513 2. The set of methods that must be supported by each interface. 514 3. The parameters and responses that must be supported by each method. 515 516 517 The abstract registry service neither defines any specific implementation for the ebXML Registry, nor does it specify any specific protocols used by the registry. Such implementation details are described by concrete registry services that realize the abstract registry service. 518 519 520 The abstract registry service (Figure 3) shows how an abstract ebXML Registry must provide two key functional interfaces called QueryManager1 (QM) and LifeCycleManager2 (LM). 521 522 Figure 3: The Abstract ebXML Registry Service 523 524 Appendix A provides hyperlinks to the abstract service definition in the Web Service Description Language (WSDL) syntax. 525 6.2.1 LifeCycleManager Interface 526 527 528 529 530 This is the interface exposed by the Registry Service that implements the object lifecycle management functionality of the Registry. Its methods are invoked by the Registry Client. For example, the client may use this interface to submit objects, to classify and associate objects and to deprecate and remove objects. For this specification the semantic meaning of submit, classify, associate, deprecate and remove is found in [ebRIM]. 531 Table 2: LifeCycle Manager Summary Method Summary of LifeCycleManager RegistryResponse acceptObjects(AcceptObjectsRequest req) Accepts one or more objects to a registry during object relocation. RegistryResponse approveObjects(ApproveObjectsRequest req) Approves one or more previously submitted objects. RegistryResponse deprecateObjects(DeprecateObjectsRequest req) Deprecates one or more previously submitted objects. 1 Known as ObjectQueryManager in V1.0 2 Known as ObjectManager in V1.0 Copyright © OASIS, 2002. All Rights Reserved Page 21 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 RegistryResponse removeObjects(RemoveObjectsRequest req) Removes one or more previously submitted objects from the Registry. RegistryResponse submitObjects(SubmitObjectsRequest req) Submits one or more objects and possibly related metadata such as Associations and Classifications. RegistryResponse updateObjects(UpdateObjectsRequest req) Updates one or more previously submitted objects. RegistryResponse addSlots(AddSlotsRequest req) Add slots to one or more registry entries. RegistryResponse relocateObjects(RelocateObjectsRequest req) Relocate one or more objects from one registry to another. RegistryResponse removeSlots(RemoveSlotsRequest req) Remove specified slots from one or more registry entries. 532 6.2.2 QueryManager Interface 533 534 535 This is the interface exposed by the Registry that implements the Query management service of the Registry. Its methods are invoked by the Registry Client. For example, the client may use this interface to perform browse and drill down queries or ad hoc queries on registry content. 536 Table 3: Query Manager Method Summary of QueryManager GetContentResponse getContent(GetContentRequest req) Submit an ad hoc query request. This method is being deprecated and may go away in version 4. GetNotificationsResponse getNotifications(GetNotificationsRequest req) Submit a request to get event notifications. AdhocQueryResponse submitAdhocQuery(AdhocQueryRequest req) Submit an ad hoc query request. RegistryObject getRegistryObject(String id) Submit a request to get the RegistryObject that matches the specified id. RepositoryItem getRepositoryItem(String id) Submit a request to get the repository item that matches the specified id. This is the same as the id of the ExtrinsicObject that catalogs this repository item. 537 538 6.3 Concrete Registry Services 539 540 The architecture allows the abstract registry service to be mapped to one or more concrete registry services defined as: Copyright © OASIS, 2002. All Rights Reserved Page 22 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 541 542 543 544 545 546 This specification describes the following concrete bindings for the abstract registry service: A SOAP binding using the HTTP protocol An ebXML Messaging Service (ebMS) binding A REST binding 547 548 549 550 A registry must implement at least one concrete binding between SOAP and ebMS concrete bindings for the abstract registry service as shown in Figure 4. In addition a registry must implement the REST binding for the abstract registry service as shown in Figure 4. Need to update fig 4 and following text to include REST?? Implementations of the interfaces defined by the abstract registry service. Bindings of these concrete interfaces to specific communication protocols. 551 552 553 Figure 4: A Concrete ebXML Registry Service 554 555 556 Figure 4 shows a concrete implementation of the abstract ebXML Registry (RegistryService) on the left side. The RegistryService provides the QueryManager and LifeCycleManager interfaces available with multiple protocol bindings (SOAP and ebMS). 557 558 559 560 Figure 4 also shows two different clients of the ebXML Registry on the right side. The top client uses SOAP interface to access the registry while the lower client uses ebMS interface. Clients use the appropriate concrete interface within the RegistryService service based upon their protocol preference. 561 6.4 SOAP Binding 562 6.4.1 WSDL Terminology Primer 563 564 565 566 567 568 569 This section provides a brief introduction to Web Service Description Language (WSDL) since the SOAP binding is described using WSDL syntax. WSDL provides the ability to describe a web service in abstract as well as with concrete bindings to specific protocols. In WSDL, an abstract service consists of one or more port types or end-points. Each port type consists of a collection of operations. Each operation is defined in terms of messages that define what data is exchanged as part of that operation. Each message is typically defined in terms of elements within an XML Schema definition. 570 571 572 573 An abstract service is not bound to any specific protocol (e.g. SOAP). In WSDL, an abstract service may be used to define a concrete service by binding it to a specific protocol. This binding is done by providing a binding definition for each abstract port type that defines additional protocols specific details. Finally, a concrete service definition is defined as a collection of Copyright © OASIS, 2002. All Rights Reserved Page 23 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 574 ports, where each port simply adds address information such as a URL for each concrete port. 575 6.4.2 Concrete Binding for SOAP 576 577 578 579 580 581 582 583 584 585 586 587 588 589 590 591 592 593 594 595 This section assumes that the reader is somewhat familiar with SOAP and WSDL. The SOAP binding to the ebXML Registry is defined as a web service description in WSDL as follows: A single service element with name “RegistryService” defines the concrete SOAP binding for the registry service. The service element includes two port definitions, where each port corresponds with one of the interfaces defined for the abstract registry service. Each port includes an HTTP URL for accessing that port. Each port definition also references a binding element, one for each interface defined in the WSDL for the abstract registry service. 596 597 The complete WSDL description for the SOAP binding can be obtained via a hyperlink in Appendix A. 598 6.5 ebXML Message Service Binding 599 6.5.1 Service and Action Elements 600 601 602 603 604 605 606 607 608 609 610 When using the ebXML Messaging Services Specification, ebXML Registry Service elements correspond to Messaging Service elements as follows: The value of the Service element in the MessageHeader is an ebXML Registry Service interface name (e.g., “LifeCycleManager”). The type attribute of the Service element should have a value of “ebXMLRegistry”. The value of the Action element in the MessageHeader is an ebXML Registry Service method name (e.g., “submitObjects”). 611 612 613 Note that the above allows the Registry Client only one interface/method pair per message. This implies that a Registry Client can only invoke one method on a specified interface for a given request to a registry. 614 6.5.2 Synchronous and Asynchronous Responses 615 All methods on interfaces exposed by the registry return a response message. <service name = "RegistryService"> <port name = "QueryManagerSOAPBinding" binding = "tns:QueryManagerSOAPBinding"> <soap:address location = "http://your_URL_to_your_QueryManager"/> </port> <port name = "LifeCycleManagerSOAPBinding" binding = "tns:LifeCycleManagerSOAPBinding"> <soap:address location = "http://your_URL_to_your_QueryManager"/> </port> </service> <eb:Service eb:type=”ebXMLRegistry”>LifeCycleManger</eb:Service> <eb:Action>submitObjects</eb:Action> Copyright © OASIS, 2002. All Rights Reserved Page 24 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 616 6.5.2.1 617 618 619 620 621 622 When a message is sent asynchronously, the Registry will return two response messages. The first message will be an immediate response to the request and does not reflect the actual response for the request. This message will contain: MessageHeader RegistryResponse element including: o status attribute with value Unavailable 623 624 625 626 627 628 629 630 The Registry delivers the actual Registry response element with non-empty content asynchronously at a later time. The delivery is accomplished by the Registry invoking the onResponse method on the RegistryClient interface as implemented by the registry client application. The onResponse method includes a RegistryResponse element as shown below: MessageHeader RegistryResponse element including: o Status attribute (Success, Failure) o Optional RegistryErrorList 631 6.5.2.2 632 633 634 635 636 637 When a message is sent synchronously, the Message Service Handler will hold open the communication mechanism until the Registry returns a response. This message will contain: MessageHeader RegistryResponse element including: o Status attribute (Success, Failure) o Optional RegistryErrorList 638 6.5.3 ebXML Registry Collaboration Profiles and Agreements 639 640 641 642 The ebXML CPP specification [ebCPP] defines a Collaboration-Protocol Profile (CPP) and a Collaboration-Protocol Agreement (CPA) as mechanisms for two parties to share information regarding their respective business processes. That specification assumes that a CPA has been agreed to by both parties in order for them to engage in B2B interactions. 643 644 645 646 This specification does not mandate the use of a CPA between the Registry and the Registry Client. However if the Registry does not use a CPP, the Registry shall provide an alternate mechanism for the Registry Client to discover the services and other information provided by a CPP. This alternate mechanism could be a simple URL. 647 648 649 The CPA between clients and the Registry should describe the interfaces that the Registry and the client expose to each other for Registry-specific interactions. The definition of the Registry CPP template and a Registry Client CPP template are beyond the scope of this document. 650 6.6 REST Binding 651 652 653 654 The ebXML Registry abstract interface defines a REST binding that enables access to the registry over HTTP protocol. REST [RESTThesis], which stands for Representational State Transfer, is an architectural style for distributed hypermedia systems. The REST architectural style suggests that: Asynchronous response Synchronous response Copyright © OASIS, 2002. All Rights Reserved Page 25 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 655 656 657 658 659 660 661 662 663 664 o A service be accessible over HTTP o All access to the service capabilities and resources are via URIs REST is more of a concept than a technology or a specification. It is easily implemented using standard facilities found on a web server or development environment. The REST binding maps the abstract registry interfaces to a REST styled HTTP interface. It defines the URI parameters and their usage patterns that must be used to specify the interface, method and invocation parameters in order to invoke a method on a registry interface such as the QueryManager interface. The REST binding also defines the return values that are synchronously sent back to the client as the HTTP response for the HTTP request. 665 6.6.1 Standard URI Parameters 666 667 668 This section defines the normative URI parameters that must be supported by the REST Interface. A Registry may implement additional URI parameters in addition to these parameters. URI Parameter Name Required Description Example YES Defines the interface or object Example: QueryManager to call methods on. method YES Defines the method to be carried out on the given interface. Example: submitAdhocQueryRequest param-<key> NO Defines named parameters to be passed into a method call. Example: param-id=888-9998877h interface Table 4: Standard URI Parameters 669 670 671 6.6.2 QueryManager REST Interface 672 673 674 675 676 The REST Interface to QueryManager must be supported by all registries. The REST Interface to QueryManager defines that the interface parameter must be "QueryManager". In addition the following method parameters are defined by the QueryManager REST Interface. Parameters Method getNotifications Return Value GetNotificationsRequest GetNotificationsResponse Id getRegistryObject Copyright © OASIS, 2002. All Rights Reserved HTTP Request Type POST An instance of a leaf class that is a concrete sub-class of GET RegistryObject that matches the specified id. Page 26 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 Parameters Method Return Value Id getRepositoryItem submitAdhocQueryRequest AdhocQueryRequest RepositoryItem that matches the specified id. Note that a RepositoryItem may be arbitrary content (e.g. a GIF image). HTTP Request Type GET AdhocQueryResponse for the POST specified AdhocQueryRequest. Table 5: QueryManager REST Interface 677 678 679 680 Note that in the examples that follow name space declarations are omitted to conserve space. Also note that some lines may be wrapped due to lack of space. 681 6.6.2.1 682 683 684 685 686 The following example shows a getRegistryObject request. 687 6.6.2.2 688 689 690 691 692 693 694 695 696 697 698 699 700 701 702 The following example shows an ExtrinsicObject, which is a specialized sub-class of RegistryObject being returned as a response to the getRegistryObject method invocation. 703 6.6.2.3 704 705 706 707 708 The following example shows a getRepositoryItem request.

Authentication may be performed by the registry on a per message basis by verifying any digital signatures present, as well as at the HTTP transport level using Basic or Digest authentication. The details of how authentication credentials are specified for the REST interface to LifeCycleManager are left to be implementation specific. 794 6.6.5 Exception Handling 795 796 797 798 799 800 801 802 803 804 Exception handling is consistent with exception handling in other registry interface bindings. Errors must be reported in a RegistryErrorList, and sent back to the client on the same connection as the request. When errors occur, the HTTP status code and message should correspond to the error(s) being reported in the RegistryErrorList. For example, if the RegistryErrorList reports that an object wasn't found, therefore cannot be returned, an appropriate error code should be 404, with a message of "ObjectNotFoundException". A detailed list of HTTP status codes can be found in [RFC2616]. The mapping between registry exceptions and HTTP status codes is currently unspecified. 805 6.7 Registry Clients 806 6.7.1 Registry Client Described 807 808 809 810 811 812 813 814 815 816 The Registry Client interfaces may be local to the registry or local to the user. Figure 5 depicts the two possible topologies supported by the registry architecture with respect to the Registry and Registry Clients. The picture on the left side shows the scenario where the Registry provides a web based “thin client” application for accessing the Registry that is available to the user using a common web browser. In this scenario the Registry Client interfaces reside across the Internet and are local to the Registry from the user’s view. The picture on the right side shows the scenario where the user is using a “fat client” Registry Browser application to access the registry. In this scenario the Registry Client interfaces reside within the Registry Browser tool and are local to the Registry from the user’s view. The Registry Client interfaces communicate with the Registry over the Internet in this scenario. 817 818 819 820 821 A third topology made possible by the registry architecture is where the Registry Client interfaces reside in a server side business component such as a Purchasing business component. In this topology there may be no direct user interface or user intervention involved. Instead, the Purchasing business component may access the Registry in an automated manner to select possible sellers or service providers based on current business needs. Copyright © OASIS, 2002. All Rights Reserved Page 30 of 167 OASIS/ebXML Registry Services Specification v2.0 822 823 March 2016 Figure 5: Registry Architecture Supports Flexible Topologies 824 6.7.2 Registry Communication Bootstrapping 825 826 827 828 829 830 831 832 833 834 835 836 837 838 839 840 841 Before a client can access the services of a Registry, there must be some communication bootstrapping between the client and the registry. The most essential aspect of this bootstrapping process is for the client to discover addressing information (e.g. an HTTP URL) to each of the concrete service interfaces of the Registry. The client may obtain the addressing information by discovering the ebXML Registry in a public registry such as UDDI or within another ebXML Registry. In case of SOAP binding, all the info needed by the client (e.g. Registry URLs) is available in a WSDL desription for the registry. This WSDL conforms to the template WSDL description in Appendix A.1. This WSDL description may be discovered in a in a registry of registries. In case of ebMS binding, the information exchange between the client and the registry may be accomplished in a registry specific manner, which may involve establishing a CPA between the client and the registry. Once the information exchange has occurred the Registry and the client will have addressing information (e.g. URLs) for the other party. In case of REST binding the client may obtain the base URL to the registry by a lookup in a registry of registries. 842 6.7.2.1 843 844 845 Each ebXML Registry must provide a WSDL description for its RegistryService as defined by Appendix A.1. A client uses the WSDL description to determine the address information of the RegistryService in a protocol specific manner. For example the SOAP/HTTP based ports of the Communication Bootstrapping for SOAP Binding Copyright © OASIS, 2002. All Rights Reserved Page 31 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 846 RegistryService may be accessed via a URL specified in the WSDL for the registry. 847 848 The use of WSDL enables the client to use automated tools such as a WSDL compiler to generate stubs that provide access to the registry in a language specific manner. 849 850 851 At minimum, any client may access the registry over SOAP/HTTP using the address information within the WSDL, with minimal infrastructure requirements other than the ability to make synchronous SOAP call to the SOAP based ports on the RegistryService. 852 6.7.2.2 853 854 855 856 857 858 859 860 861 862 Since there is no previously established CPA between the Registry and the RegistryClient, the client must know at least one Transport-specific communication address for the Registry. This communication address is typically a URL to the Registry, although it could be some other type of address such as an email address. For example, if the communication used by the Registry is HTTP, then the communication address is a URL. In this example, the client uses the Registry’s public URL to create an implicit CPA with the Registry. When the client sends a request to the Registry, it provides a URL to itself. The Registry uses the client’s URL to form its version of an implicit CPA with the client. At this point a session is established within the Registry. For the duration of the client’s session with the Registry, messages may be exchanged bi-directionally as required by the interaction protocols defined in this specification. 863 6.7.2.3 864 865 Communication between a client and the REST interface is established based upon the base URL of the REST interface to the registry. No other communication bootstrapping is required. 866 6.7.3 RegistryClient Interface 867 868 869 870 871 This is the principal interface implemented by a Registry client. The client provides this interface when creating a connection to the Registry. It provides the methods that are used by the Registry to deliver asynchronous responses to the client. Note that a client need not provide a RegistryClient interface if the [CPA] between the client and the registry does not support asynchronous responses. 872 The registry sends all asynchronous responses to operations via the onResponse method. Communication Bootstrapping for ebXML Message Service Binding Communication Bootstrapping for REST Binding Table 7: RegistryClient Summary 873 Method Summary of RegistryClient void onResponse(RegistryResponse resp) Notifies client of the response sent by registry to previously submitted request. 874 6.7.4 Registry Response 875 876 The RegistryResponse is a common class defined by the Registry interface that is used by the registry to provide responses to client requests.

An ebXML Registry must implement a REST binding and either or both of the ebMS and SOAP/HTTP bindings. Copyright © OASIS, 2002.

The Lifecycle Management Service is a sub-service of the Registry service. It provides the functionality required by RegistryClients to manage the lifecycle of repository items (e.g. XML documents required for ebXML business processes). The Lifecycle Management Service can be used with all types of repository items as well as the metadata objects specified in [ebRIM] such as Classification and Association. 890 891 892 The minimum-security policy for an ebXML registry is to accept content from any client if a certificate issued by a Certificate Authority recognized by the ebXML registry digitally signs the content. 893 7.1 Lifecycle of a RegistryObject 894 895 896 The main purpose of the LifeCycleManagement service is to manage the lifecycle of RegistryObjects. Figure 6 shows the typical lifecycle of a RegistryObject. Fix picture to show a link from Submitted to Removed from RegistryObject?? 897 898 Figure 6: Lifecycle of a RegistryObject 899 7.2 RegistryObject Attributes 900 901 902 903 904 A repository item is associated with a set of standard metadata defined as attributes of the RegistryObject class and its sub-classes as described in [ebRIM]. These attributes reside outside of the actual repository item and catalog descriptive information about the repository item. XML elements called ExtrinsicObject and other elements (See Appendix B.1 for details) encapsulate all object metadata attributes defined in [ebRIM] as XML attributes. Copyright © OASIS, 2002. All Rights Reserved Page 34 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 905 7.3 The Submit Objects Protocol 906 907 908 This section describes the protocol of the Registry Service that allows a RegistryClient to submit one or more RegistryObjects and/or repository items using the LifeCycleManager on behalf of a Submitting Organization. It is expressed in UML notation as described in Appendix C. 909 910 Figure 7: Submit Objects Sequence Diagram 911 For details on the schema for the Business documents shown in this process refer to Appendix B. 912 7.3.1 SubmitObjectsRequest 913 914 The SubmitObjectsRequest is used by a client to submit RegistryObjects and/or repository items to the registry. 915 7.3.1.1 Syntax: 916 917 918 919 920 921 Figure 8: SubmitObjectsRequest Syntax 7.3.1.2 Parameters: indexingOption: Change to catalog. This parameter specifies the submitter’s preference governing the indexing of the objects submitted via this request. Valid values are: 922 923 NoIndexing: This specifies that the registry must not index any of the objects submitted via this request. 924 925 IndexModificationNotAllowed: This specifies that the registry may index any of the objects submitted via this request as long as the original objects Copyright © OASIS, 2002. All Rights Reserved Page 35 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 926 are not modified by the indexing operations. 927 928 929 IndexModificationAllowed: This specifies that the registry may index any of the objects submitted via this request even if the original objects are are modified by the indexing operations. 930 931 LeafRegistryObjectsList: This parameter specifies a collection of RegistryObject instances that are being submitted to the registry. 932 933 7.3.1.3 934 This request returns a RegistryResponse. See section 7.3.2 for details. 935 7.3.1.4 936 In addition to the exceptions common to all requests, the following exceptions may be returned: Returns: Exceptions: 937 938 AuthorizationException: Indicates that the requestor attempted to perform an operation for which she was not authorized. 939 940 ObjectNotFoundException: Indicates that the requestor referenced an object within the request that was not found. 941 942 ObjectExistsException: Indicates that the requestor tried to submit an object using an id that matched the id of an existing object in the registry. 943 944 InvalidRequestException: Indicates that the requestor attempted to perform an operation which was semantically invalid. 945 946 UnsupportedCapabilityException: Indicates that the requestor attempted to submit some content that is not supported by the registry. 947 948 QuotaExceededException: Indicates that the requestor attempted to submit more content than the quota allowed for them by the registry. 949 950 7.3.2 RegistryResponse 951 952 953 The RegistryResponse is sent by the registry as a response to several different requests. It is a simple response that can signal the status of a request and any errors or exceptions that may have occurred during the processing of that request. 954 955 7.3.2.1 Syntax: 956 Copyright © OASIS, 2002. All Rights Reserved Page 36 of 167 OASIS/ebXML Registry Services Specification v2.0 Figure 9: RegistryResponse Syntax 957 958 March 2016 7.3.2.2 Parameters: 959 960 requestId: This parameter specifies the id of the request that generated this response. It is used to correlate the response with its request. 961 962 status: This parameter specifies the status of the request. Valid values are as follows: 963 964 965 966 967 968 969 Success: Request was processed successfully. Failure: Errors were encountered during the processing of the request. Unavailable: The results are unavailable. This is useful in asynchronous responses. RegistryErrorList: This parameter specifies a collection of RegistryErrors. RegistryError is defined in ??. A RegistryErrorList includes a highestSeverity attribute which logs the ErrorType for the most severe error that occurred. 970 971 7.3.3 Universally Unique ID Generation 972 973 974 As specified by [ebRIM], all objects in the registry have a unique id. The id must be a Universally Unique Identifier (UUID) and must conform to the format of a URN that specifies a DCE 128 bit UUID as specified in [UUID]. 975 (e.g. urn:uuid:a2345678-1234-1234-123456789012) 976 977 978 979 980 981 The registry usually generates this id. The client may optionally supply the id attribute for submitted objects. If the client supplies the id and it conforms to the format of a URN that specifies a DCE 128 bit UUID then the registry assumes that the client wishes to specify the id for the object. In this case, the registry must honour a client-supplied id and use it as the id attribute of the object in the registry. If the id is not unique within the registry, the registry must return ObjectExistsException. 982 983 984 If the client does not supply an id for a submitted object then the registry must generate a universally unique id. Whether the client generates the id or whether the registry generates it, it must be generated using the DCE 128 bit UUID generation algorithm as specified in [UUID]. 985 7.3.4 ID Attribute And Object References 986 987 988 989 990 991 992 993 994 995 The id attribute of an object may be used by other objects to reference the first object. Such references are common both within the SubmitObjectsRequest as well as within the registry. Within a SubmitObjectsRequest, the id attribute may be used to refer to an object within the SubmitObjectsRequest as well as to refer to an object within the registry. An object in the SubmitObjectsRequest that needs to be referred to within the request document may be assigned an id by the submitter so that it can be referenced within the request. The submitter may give the object a proper UUID URN, in which case the id is permanently assigned to the object within the registry. Alternatively, the submitter may assign an arbitrary id (not a proper UUID URN) as long as the id is unique within the request document. In this case the id serves as a linkage mechanism within the request document but must be ignored by the registry and replaced with a Copyright © OASIS, 2002. All Rights Reserved Page 37 of 167 OASIS/ebXML Registry Services Specification v2.0 996 March 2016 registry generated UUID upon submission. 997 998 999 1000 When an object in a SubmitObjectsRequest needs to reference an object that is already in the registry, the request must contain an ObjectRef whose id attribute is the id of the object in the registry. This id is by definition a proper UUID URN. An ObjectRef may be viewed as a proxy within the request for an object that is in the registry. 1001 7.3.5 Audit Trail 1002 1003 The RS must create AuditableEvent objects with eventType Created for each RegistryObject created via a SubmitObjectsRequest. 1004 7.3.6 Error Handling 1005 1006 1007 1008 1009 1010 1011 1012 Need to move to a generic section on error handling?? A request is atomic and either succeeds or fails in total. In the event of success, the registry sends a RegistryResponse with a status of “Success” back to the client. In the event of failure, the registry sends a RegistryResponse with a status of “Failure” back to the client. In the event of an immediate response for an asynchronous request, the registry sends a RegistryResponse with a status of “Unavailable” back to the client. Failure occurs when one or more Error conditions are raised in the processing of the submitted objects. Warning messages do not result in failure of the request. 1013 7.3.7 Sample SubmitObjectsRequest 1014 1015 1016 1017 1018 1019 1020 1021 1022 1023 1024 1025 1026 1027 1028 1029 1030 1031 1032 1033 1034 1035 1036 1037 1038 1039 1040 1041 1042 1043 1044 1045 1046 The following example shows several different use cases in a single SubmitObjectsRequest. It does not show the complete SOAP or [ebMS] Message with the message header and additional payloads in the message for the repository items. A SubmitObjectsRequest includes a RegistryObjectList which contains any number of objects that are being submitted. It may also contain any number of ObjectRefs to link objects being submitted to objects already within the registry. <?xml version = "1.0" encoding = "UTF-8"?> <SubmitObjectsRequest xmlns = "urn:oasis:names:tc:ebxml-regrep:registry:xsd:2.0" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation = "urn:oasis:names:tc:ebxml-regrep:rim:xsd:2.0 file:///C:/osws/ebxmlrrspec/misc/schema/rim.xsd urn:oasis:names:tc:ebxml-regrep:registry:xsd:2.0 file:///C:/osws/ebxmlrr-spec/misc/schema/rs.xsd" xmlns:rim = "urn:oasis:names:tc:ebxml-regrep:rim:xsd:2.0" xmlns:rs = "urn:oasis:names:tc:ebxml-regrep:registry:xsd:2.0" > <rim:LeafRegistryObjectList> <!-The following 3 objects package specified ExtrinsicObject in specified RegistryPackage, where both the RegistryPackage and the ExtrinsicObject are being submitted --> <rim:RegistryPackage id = "acmePackage1" > <rim:Name> <rim:LocalizedString value = "RegistryPackage #1"/> </rim:Name> <rim:Description> <rim:LocalizedString value = "ACME's package #1"/> </rim:Description> Copyright © OASIS, 2002.

The Registry supports the following query capabilities: Filter Query SQL Query 1459 1460 1461 1462 The Filter Query mechanism in Section 8.2 must be supported by every Registry implementation. The SQL Query mechanism is an optional feature and may be provided by a registry implementation. However, if a vendor provides an SQL query capability to an ebXML Registry it must conform to this document. As such this capability is a normative yet optional capability. 1463 1464 In a future version of this specification, the W3C XQuery syntax may be considered as another query syntax. 1465 1466 The Registry will hold a self-describing capability profile that identifies all supported AdhocQuery options. This profile is described in Appendix G. 1467 8.1 Ad Hoc Query Request/Response 1468 1469 1470 A client submits an ad hoc query to the QueryManager by sending an AdhocQueryRequest. The AdhocQueryRequest contains a sub-element that defines a query in one of the supported Registry query mechanisms. 1471 1472 1473 1474 1475 The QueryManager sends an AdhocQueryResponse either synchronously or asynchronously back to the client. The AdhocQueryResponse returns a collection of objects whose element type depends upon the responseOption attribute of the AdhocQueryRequest. These may be objects representing leaf classes in [ebRIM], references to objects in the registry as well as intermediate classes in [ebRIM] such as RegistryObject and RegistryEntry. 1476 1477 Any errors in the query request messages are indicated in the corresponding AdhocQueryResponse message.

If unspecified, the registry should return either all the results, or in case the result set size exceeds a registry specific limit, the registry should return a sub-set of results that are within the bounds of the registry specific limit. See section 8.1.4.1 for an illustrative example. 1494 1495 ResponseOption: This required parameter allows the client to control the format and content of the AdhocQueryResponse to this request. See section 8.1.3 for Copyright © OASIS, 2002. All Rights Reserved Page 52 of 167 OASIS/ebXML Registry Services Specification v2.0 1496 March 2016 details. 1497 SQLQuery: This parameter specifies a registry SQL Query. 1498 1499 1500 1501 startIndex: This optional integer value is used to indicate which result must be returned as the first result when iterating over a large result set. The default value is 0, which returns the result set starting with index 0 (first result). See section 8.1.4.1 for an illustrative example. 1502 1503 8.1.1.3 1504 This request returns an AdhocQueryResponse. See section 9.6.2 for details. 1505 8.1.1.4 1506 In addition to the exceptions common to all requests, the following exceptions may be returned: Returns: Exceptions: 1507 1508 AuthorizationException: Indicates that the requestor attempted to perform an operation for which she was not authorized. 1509 1510 InvalidQueryException: signifies that the query syntax or semantics was invalid. Client must fix the query syntax or semantic and re-submit the query. 1511 1512 TimeoutException: signifies that the processing time exceeded a registry specific limit. Move to generic exceptions lists somehwhere?? 1513 8.1.2 AdhocQueryResponse 1514 The AdhocQueryRequest sent by the registry as a response to AdhocQueryRequest. 1515 1516 1517 1518 1519 8.1.2.1 Syntax: Figure 23: AdhocQueryResponse Syntax Update picture to show it inherits from RegistryResponse?? 8.1.2.2 Parameters: 1520 FilterQueryResult: This parameter specifies the result of a registry Filter Query. 1521 SQLQueryResult: This parameter specifies the result of a registry SQL Query. 1522 1523 1524 1525 startIndex: This optional integer value is used to indicate the index for the first result in the result set returned by the query, within the complete result set matching the query. By default, this value is 0. See section 8.1.4.1 for an illustrative example. Copyright © OASIS, 2002. All Rights Reserved Page 53 of 167 OASIS/ebXML Registry Services Specification v2.0 1526 1527 1528 1529 1530 March 2016 totalResultCount: This optional parameter specifies the size of the complete result set matching the query within the registry. When this value is unspecified, the client should assume that value is the size of the result set contained within the result. See section 8.1.4.1 for an illustrative example. 1531 8.1.3 ReponseOption 1532 1533 A client specifies an ResponseOption structure within an AdhocQueryRequest to indicate the format of the results within the corresponding AdhocQueryResponse. 1534 1535 8.1.3.1 Syntax: 1536 1537 Figure 24: ResponseOption Syntax 1538 1539 8.1.3.2 Parameters: 1540 1541 1542 1543 returnComposedObjects: This optional parameter specifies whether the RegistryObjects returned should include composed objects such as Classifications, ExternalIdentifiers etc. The default is to return all composed objects. 1544 1545 1546 1547 1548 1549 1550 1551 1552 1553 1554 1555 1556 1557 1558 1559 1560 1561 returnType: This optional enumeration parameter specifies the type of RegistryObject to return within the response. Enumeration values for returnType are explained in section 0. Values for returnType are as follows: ObjectRef - This option specifies that the AdhocQueryResponse may contain a collection of ObjectRef XML elements as defined in [ebRIM Schema]. Purpose of this option is to return references to registry objects. RegistryObject - This option specifies that the AdhocQueryResponse may contain a collection of RegistryObject XML elements as defined in [ebRIM Schema]. In this case all attributes of the registry objects are returned (objectType, name, description, …). RegistryEntry - This option specifies that the AdhocQueryResponse may contain a collection of RegistryEntry or RegistryObject XML elements as defined in [ebRIM Schema], which correspond to RegistryEntry or RegistryObject attributes. LeafClass - This option specifies that the AdhocQueryResponse may contain a collection of XML elements that correspond to leaf classes as defined in [ebRIM Schema]. Copyright © OASIS, 2002. All Rights Reserved Page 54 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 1562 1563 1564 1565 1566 1567 1568 1569 1570 If “returnType” specified does not match a result returned by the query, then the registry must use the closest matching semantically valid returnType that matches the result. 1571 1572 1573 1574 This can be illustrated with a case when OrganizationQuery is asked to return LeafClassWithRepositoryItem. As this is not possible, QueryManager will assume LeafClass option instead. If OrganizationQuery is asked to retrieve a RegistryEntry as a return type then RegistryObject metadata will be returned. LeafClassWithRepositoryItem - This option specifies that the AdhocQueryResponse may contain a collection of ExtrinsicObject XML elements as defined in [ebRIM Schema] accompanied with their repository items or RegistryEntry or RegistryObject and their attributes. Linking of ExtrinsicObject and its repository item is accomplished using the technique explained in Section 8.4 -Content Retrieval. 1575 8.1.4 Iterative Query Support 1576 1577 1578 1579 1580 1581 1582 1583 1584 1585 1586 1587 1588 The iterative query feature is a normative optional feature of the registry. The AdhocQueryRequest and AdhocQueryResponse support the ability to iterate over a large result set matching a logical query by allowing multiple AdhocQueryRequest requests to be submitted such that each query requests a different sliding window within the result set. This feature enables the registry to handle queries that match a very large result set, in a scalable manner. The iterative queries feature is not a true Cursor capability as found in databases. The registry is not required to maintain transactional consistency or state between iterations of a query. Thus it is possible for new objects to be added or existing objects to be removed from the complete result set in between iterations. As a consequence it is possible to have a result set element be skipped or duplicated between iterations. Note that while it is not required, it may be possible for implementations to be smart and implement a transactionally consistent iterative query feature. It is likely that a future version of this specification will require a transactionally consistent iterative query capability. 1589 8.1.4.1 1590 1591 1592 1593 1594 1595 Consider the case where there are 1007 Organizations in a registry. The user wishes to submit a query that matches all 1007 Organizations. The user wishes to do the query iteratively such that Organizations are retrieved in chunks of 100. The following table illustrates the parameters of the AdhocQueryRequest and those of the AdhocQueryResponses for each iterative query in this example.

Filter Query changes to support new objects like Subscriptions.?? 1600 1601 1602 1603 1604 1605 1606 1607 1608 1609 1610 1611 1612 FilterQuery is an XML syntax that provides simple query capabilities for any ebXML conforming Registry implementation. Each query alternative is directed against a single class defined by the ebXML Registry Information Model (ebRIM). There are two types of filter queries depending on which classes are queried on. Firstly, there are RegistryObjectQuery and RegistryEntryQuery. They allow for generic queries that might return different subclasses of the class that is queried on. The result of such a query is a set of XML elements that correspond to instances of any class that satisfies the responseOption defined previously in Section 8.1.3. An example might be that RegistryObjectQuery with responseOption LeafClass will return all attributes of all instances that satisfy the query. This implies that response might return XML elements that correspond to classes like ClassificationScheme, RegistryPackage, Organization and Service. Secondly, FilterQuery supports queries on selected ebRIM classes in order to define the exact traversals of these classes. Responses to these queries are accordingly constrained. 1613 1614 1615 1616 A client submits a FilterQuery as part of an AdhocQueryRequest. The QueryManager sends an AdhocQueryResponse back to the client, enclosing the appropriate FilterQueryResult specified herein. The sequence diagrams for AdhocQueryRequest and AdhocQueryResponse are specified in Section 8.1. 1617 1618 1619 1620 1621 Each FilterQuery alternative is associated with an ebRIM Binding that identifies a hierarchy of classes derived from a single class and its associations with other classes as defined by ebRIM. Each choice of a class pre-determines a virtual XML document that can be queried as a tree. For example, let C be a class, let Y and Z be classes that have direct associations to C, and let V be a class that is associated with Z. The ebRIM Binding for C might be as in Figure 25 Copyright © OASIS, 2002. All Rights Reserved Page 56 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 1622 1623 Figure 25: Example ebRIM Binding 1624 1625 1626 1627 1628 1629 Label1 identifies an association from C to Y, Label2 identifies an association from C to Z, and Label3 identifies an association from Z to V. Labels can be omitted if there is no ambiguity as to which ebRIM association is intended. The name of the query is determined by the root class, i.e. this is an ebRIM Binding for a CQuery. The Y node in the tree is limited to the set of Y instances that are linked to C by the association identified by Label1. Similarly, the Z and V nodes are limited to instances that are linked to their parent node by the identified association. 1630 1631 1632 1633 1634 1635 1636 1637 1638 1639 Each FilterQuery alternative depends upon one or more class filters, where a class filter is a restricted predicate clause over the attributes of a single class. Class methods that are defined in ebRIM and that return simple types constitute “visible attributes” that are valid choices for predicate clauses. Names of those attributes will be same as name of the corresponding method just without the prefix ‘get’. For example, in case of “getLevelNumber” method the corresponding visible attribute is “levelNumber”. The supported class filters are specified in Section 8.2.13 and the supported predicate clauses are defined in Section 8.2.14. A FilterQuery will be composed of elements that traverse the tree to determine which branches satisfy the designated class filters, and the query result will be the set of instances that support such a branch. 1640 1641 1642 1643 1644 1645 1646 In the above example, the CQuery element will have three subelements, one a CFilter on the C class to eliminate C instances that do not satisfy the predicate of the CFilter, another a YFilter on the Y class to eliminate branches from C to Y where the target of the association does not satisfy the YFilter, and a third to eliminate branches along a path from C through Z to V. The third element is called a branch element because it allows class filters on each class along the path from C to V. In general, a branch element will have subelements that are themselves class filters, other branch elements, or a full-blown query on the class in the path. 1647 1648 1649 1650 1651 If an association from a class C to a class Y is one-to-zero or one-to-one, then at most one branch, filter or query element on Y is allowed. However, if the association is one-to-many, then multiple branch, filter or query elements are allowed. This allows one to specify that an instance of C must have associations with multiple instances of Y before the instance of C is said to satisfy the branch element. 1652 1653 1654 1655 The FilterQuery syntax is tied to the structures defined in ebRIM. Since ebRIM is intended to be stable, the FilterQuery syntax is stable. However, if new structures are added to the ebRIM, then the FilterQuery syntax and semantics can be extended at the same time. Also, FilterQuery syntax follows the inheritance hierarchy of ebRIM, which means that subclass queries inherit from their Copyright © OASIS, 2002. All Rights Reserved Page 57 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 1656 1657 1658 respective superclass queries. Structures of XML elements that match the ebRIM classes are explained in [ebRIM Schema]. Names of Filters, Queries and Branches correspond to names in ebRIM whenever possible. 1659 1660 1661 The ebRIM Binding paragraphs in Sections 8.2.2 through 8.2.12 below identify the virtual hierarchy for each FilterQuery alternative. The Semantic Rules for each query alternative specify the effect of that binding on query semantics. 1662 8.2.1 FilterQuery 1663 1664 1665 1666 Purpose 1667 1668 1669 1670 1671 1672 1673 1674 1675 1676 1677 1678 1679 1680 1681 1682 1683 1684 1685 1686 1687 1688 1689 1690 1691 1692 1693 1694 1695 1696 1697 1698 1699 1700 1701 1702 1703 1704 Definition To identify a set of queries that traverse specific registry class.

The semantic rules for each FilterQuery alternative are specified in subsequent subsections. 1707 1708 1709 2. Semantic rules specify the procedure for implementing the evaluation of Filter Queries. Implementations do not necessarily have to follow the same procedure provided that the same effect is achieved. 1710 1711 1712 3. Each FilterQueryResult is a set of XML elements to identify each instance of the result set. Each XML attribute carries a value derived from the value of an attribute specified in the Registry Information Model [ebRIM Schema]. 1713 1714 1715 4. For each FilterQuery subelement there is only one corresponding FilterQueryResult subelement that must be returned as a response. Class name of the FilterQueryResult subelement has to match the class name of the FilterQuery subelement. 1716 1717 5.

If an error condition is raised during any part of the execution of a FilterQuery, then the status attribute of the XML RegistryResult is set to “failure” and no AdHocQueryResult element is returned; instead, a RegistryErrorList element must be returned with its highestSeverity element set to “error”. At least one of the RegistryError elements in the RegistryErrorList will have its severity attribute set to “error”. 1723 1724 1725 1726 1727 7. If no error conditions are raised during execution of a FilterQuery, then the status attribute of the XML RegistryResult is set to “success” and an appropriate FilterQueryResult element must be included. If a RegistryErrorList is also returned, then the highestSeverity attribute of the RegistryErrorList is set to “warning” and the serverity attribute of each RegistryError is set to “warning”. 1728 8.2.2 RegistryObjectQuery 1729 Purpose 1730 1731 To identify a set of registry object instances as the result of a query over selected registry metadata. 1732 ebRIM Binding Copyright © OASIS, 2002.

Since the RegistryPackageQuery is not set up to do negations, clients will have to do two separate RegistryPackageQuery requests, one to find all packages and another to find all non-empty packages, and then do the set difference themselves. Alternatively, they could do a more complex RegistryEntryQuery and check that the packaging association between the package and its members is non-existent. 3080 3081 3082 3083 Note: A registry package is an intrinsic RegistryEntry instance that is completely determined by its associations with its members. Thus a RegistryPackageQuery can always be re-specified as an equivalent RegistryEntryQuery using appropriate “Source” and “Target” associations.

Predicate Clauses are utilized to formally define the constraint mechanism, and are referred to simply as Clauses in this specification. 3528 Conceptual Diagram 3529 The following is a conceptual diagram outlining the Clause structure. 3530 3531 3532 Figure 37: The Clause Structure Copyright © OASIS, 2002. All Rights Reserved Page 101 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 3533 Semantic Rules 3534 3535 3536 Predicates and Arguments are combined into a "LeftArgument - Predicate - RightArgument" format to form a Clause. There are two types of Clauses: SimpleClauses and CompoundClauses. 3537 3538 3539 3540 A SimpleClause always defines the leftArgument as a text string, sometimes referred to as the Subject of the Clause. SimpleClause itself is incomplete (abstract) and must be extended. SimpleClause is extended to support BooleanClause, StringClause, and RationalClause (abstract). 3541 3542 3543 3544 3545 3546 3547 BooleanClause implicitly defines the predicate as ‘equal to’, with the right argument as a boolean. StringClause defines the predicate as an enumerated attribute of appropriate stringcompare operations and a right argument as the element’s text data. Rational number support is provided through a common RationalClause providing an enumeration of appropriate rational number compare operations, which is further extended to IntClause and FloatClause, each with appropriate signatures for the right argument. 3548 3549 A CompoundClause contains two or more Clauses (Simple or Compound) and a connective predicate. This provides for arbitrarily complex Clauses to be formed. 3550 3551 3552 3553 3554 3555 3556 3557 3558 3559 3560 3561 3562 3563 3564 3565 3566 3567 3568 3569 3570 3571 3572 3573 3574 3575 3576 3577 3578 3579 3580 3581 3582 3583 Definition SimpleClauses CompoundClauses <element name = "Clause"> <annotation> <documentation xml:lang = "en"> The following lines define the XML syntax for Clause. </documentation> </annotation> <complexType> <choice> <element ref = "tns:SimpleClause"/> <element ref = "tns:CompoundClause"/> </choice> </complexType> </element> <element name = "SimpleClause"> <complexType> <choice> <element ref = "tns:BooleanClause"/> <element ref = "tns:RationalClause"/> <element ref = "tns:StringClause"/> </choice> <attribute name = "leftArgument" use = "required" type = "string"/> </complexType> </element> <element name = "CompoundClause"> <complexType> <sequence> <element ref = "tns:Clause" maxOccurs = "unbounded"/> </sequence> <attribute name = "connectivePredicate" use = "required"> <simpleType> <restriction base = "NMTOKEN"> Copyright © OASIS, 2002.

The relational schema is an algorithmic binding to [ebRIM] as described in the following sections. 3746 8.3.1.1 3747 3748 3749 A subset of the class names defined in [ebRIM] map to table names that may be queried by an SQL query. Appendix D.3 defines the names of the ebRIM classes that may be queried by an SQL query. 3750 3751 3752 3753 3754 3755 3756 3757 3758 3759 3760 3761 3762 The algorithm used to define the binding of [ebRIM] classes to table definitions in Appendix D.3 is as follows: Classes that have concrete instances are mapped to relational tables. In addition entity classes (e.g. PostalAddress and TelephoneNumber) are also mapped to relational tables. The intermediate classes in the inheritance hierarchy, namely RegistryObject and RegistryEntry, map to relational views. The names of relational tables and views are the same as the corresponding [ebRIM] class name. However, the name binding is case insensitive. Each [ebRIM] class that maps to a table in Appendix D.3 includes column definitions in Appendix D.3 where the column definitions are based on a subset of attributes defined for that class in [ebRIM]. The attributes that map to columns include the inherited attributes for the [ebRIM] class. Comments in Appendix D.3 indicate which ancestor class contributed which column definitions. 3763 3764 An SQLQuery against a table not defined in Appendix D.3 may raise an error condition: InvalidQueryException. 3765 3766 The following sections describe the algorithm for mapping attributes of [ebRIM] to SQLcolumn definitions. 3767 8.3.1.2 3768 3769 3770 3771 3772 Attributes defined by [ebRIM] that are of primitive types (e.g. String) may be used in the same way as column names in SQL. Again the exact attribute names are defined in the class definitions in [ebRIM]. Note that while names are in mixed case, SQL-92 is case insensitive. It is therefore valid for a query to contain attribute names that do not exactly match the case defined in [ebRIM]. 3773 8.3.1.3 3774 3775 3776 A few of the [ebRIM] class attributes are of type UUID and are a reference to an instance of a class defined by [ebRIM]. For example, the accessControlPolicy attribute of the RegistryObject class returns a reference to an instance of an AccessControlPolicy object. 3777 3778 3779 In such cases the reference maps to the id attribute for the referenced object. The name of the resulting column is the same as the attribute name in [ebRIM] as defined by 8.3.1.2. The data type for the column is VARCHAR(64) as defined in Appendix D.3. 3780 3781 When a reference attribute value holds a null reference, it maps to a null value in the SQL binding and may be tested with the <null specification> (“IS [NOT] NULL” syntax) as defined Class Binding Primitive Attributes Binding Reference Attribute Binding Copyright © OASIS, 2002. All Rights Reserved Page 106 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 3782 by [SQL]. 3783 Reference attribute binding is a special case of a primitive attribute mapping. 3784 8.3.1.4 3785 3786 3787 3788 3789 3790 3791 3792 3793 A few of the [ebRIM] interfaces define attributes that are not primitive types. Instead they are of a complex type as defined by an entity class in [ebRIM]. Examples include attributes of type TelephoneNumber, Contact, PersonName etc. in class Organization and class User. The SQL query schema does not map complex attributes as columns in the table for the class for which the attribute is defined. Instead the complex attributes are mapped to columns in the table for the domain class that represents the data type for the complex attribute (e.g. TelephoneNumber). A column links the row in the domain table to the row in the parent table (e.g. User). An additional column named ‘attribute_name’ identifies the attribute name in the parent class, in case there are multiple attributes with the same complex attribute type. 3794 3795 3796 3797 This mapping also easily allows for attributes that are a collection of a complex type. For example, a User may have a collection of TelephoneNumbers. This maps to multiple rows in the TelephoneNumber table (one for each TelephoneNumber) where each row has a parent identifier and an attribute_name. 3798 8.3.1.5 3799 3800 3801 3802 Several of the [ebRIM] classes define methods in addition to attributes, where these methods return collections of references to instances of classes defined by [ebRIM]. For example, the getPackages method of the RegistryObject class returns a Collection of references to instances of Packages that the object is a member of. 3803 3804 3805 Such collection returning methods in [ebRIM] classes have been mapped to stored procedures in Appendix D.3 such that these stored procedures return a collection of id attribute values. The returned value of these stored procedures can be treated as the result of a table sub-query in SQL. 3806 3807 These stored procedures may be used as the right-hand-side of an SQL IN clause to test for membership of an object in such collections of references. 3808 8.3.2 Semantic Constraints On Query Syntax 3809 3810 3811 This section defines simplifying constraints on the query syntax that cannot be expressed in the BNF for the query syntax. These constraints must be applied in the semantic analysis of the query. 3812 1. Class names and attribute names must be processed in a case insensitive manner. 3813 3814 2. The syntax used for stored procedure invocation must be consistent with the syntax of an SQL procedure invocation as specified by ISO/IEC 9075-4 [SQL/PSM]. 3815 3816 3. For this version of the specification, the SQL select column list consists of exactly one column, and must always be t.id, where t is a table reference in the FROM clause. 3817 8.3.3 SQL Query Results 3818 3819 The result of an SQL query resolves to a collection of objects within the registry. It never resolves to partial attributes. The objects related to the result set may be returned as an Complex Attribute Binding Binding of Methods Returning Collections Copyright © OASIS, 2002.

The entire result set is returned as a SQLQueryResult as defined by the AdHocQueryResponse in Section 8.1. 3824 8.3.4 Simple Metadata Based Queries 3825 3826 The simplest form of an SQL query is based upon metadata attributes specified for a single class within [ebRIM]. This section gives some examples of simple metadata based queries. 3827 3828 3829 3830 3831 3832 3833 3834 For example, to retrieve the collection of ExtrinsicObjects whose name contains the word ‘Acme’ and that have a version greater than 1.3, the following query must be submitted: 3835 3836 Note that the query syntax allows for conjugation of simpler predicates into more complex queries as shown in the simple example above. 3837 8.3.5 RegistryObject Queries 3838 3839 3840 The schema for the SQL query defines a view called RegistryObject that allows doing a polymorphic query against all RegistryObject instances regardless of their actual concrete type or table name. 3841 3842 3843 3844 3845 3846 3847 3848 3849 The following example is similar to the example in Section 8.3.4 except that it is applied against all RegistryObject instances rather than just ExtrinsicObject instances. The result set will include id for all qualifying RegistryObject instances whose name contains the word ‘Acme’ and whose description contains the word “bicycle”. 3850 8.3.6 RegistryEntry Queries 3851 3852 3853 The schema for the SQL query defines a view called RegistryEntry that allows doing a polymorphic query against all RegistryEntry instances regardless of their actual concrete type or table name. 3854 3855 3856 3857 3858 3859 3860 3861 3862 3863 The following example is the same as the example in Section 8.3.4 except that it is applied against all RegistryEntry instances rather than just ExtrinsicObject instances. The result set will include id for all qualifying RegistryEntry instances whose name contains the word ‘Acme’ and that have a version greater than 1.3. SELECT eo.id from ExtrinsicObject eo, Name nm where nm.value LIKE '%Acme%' AND eo.id = nm.parent AND eo.majorVersion >= 1 AND (eo.majorVersion >= 2 OR eo.minorVersion > 3); SELECT ro.id from RegistryObject ro, Name nm, Description d where nm.value LIKE '%Acme%' AND d.value LIKE '%bicycle%' AND ro.id = nm.parent AND ro.id = d.parent; SELECT re.id from RegistryEntry re, Name nm where nm.value LIKE '%Acme%' AND re.id = nm.parent AND re.majorVersion >= 1 AND (re.majorVersion >= 2 OR re.minorVersion > 3); Copyright © OASIS, 2002.

However, they may also be identified as a path attribute that specifies an XPATH expression [XPT] from a root classification node to the specified classification node in the XML document that would represent the ClassificationNode tree including the said ClassificationNode. 3871 8.3.7.2 3872 3873 3874 3875 The following query retrieves the collection of ClassificationSchemes : 3876 3877 The above query returns all ClassificationSchemes. Note that the above query may also specify additional predicates (e.g. name, description etc.) if desired. 3878 8.3.7.3 3879 3880 3881 3882 The following query retrieves the children of a ClassificationNode given the ID of that node: 3883 3884 The above query returns all ClassificationNodes that have the node specified by <id> as their parent attribute. 3885 8.3.7.4 3886 3887 3888 3889 3890 3891 3892 3893 3894 3895 3896 3897 3898 3899 3900 The following query retrieves the collection of ExtrinsicObjects classified by specified ClassificationNodes: 3901 3902 3903 3904 The above query retrieves the collection of ExtrinsicObjects that are classified by the Automotive Industry and the Japan Geography. Note that according to the semantics defined for GetClassifiedObjectsRequest, the query will also contain any objects that are classified by descendents of the specified ClassificationNodes. 3905 8.3.7.5 3906 3907 3908 3909 3910 The following query retrieves the collection of Classifications that classify a specified Object: Identifying ClassificationNodes Retrieving ClassificationSchemes SELECT scheme.id FROM ClassificationScheme scheme; Retrieving Children of Specified ClassificationNode SELECT cn.id FROM ClassificationNode cn WHERE parent = <id> Retrieving Objects Classified By a ClassificationNode SELECT id FROM ExtrinsicObject WHERE id IN (SELECT classifiedObject FROM Classification WHERE classificationNode IN (SELECT id FROM ClassificationNode WHERE path = “/Geography/Asia/Japan’)) AND id IN (SELECT classifiedObject FROM Classification WHERE classificationNode IN (SELECT id FROM ClassificationNode WHERE path = ‘/Industry/Automotive’)) Retrieving Classifications That Classify an Object SELECT id FROM Classification c WHERE c.classifiedObject = <id>; Copyright © OASIS, 2002.

The GetContentRequest specifies a list of ObjectRefs for Objects that need to be retrieved. The QueryManager returns the specified content by sending a GetContentResponse message to the RegistryClient interface of the client. 3991 3992 If there are no errors encountered, the GetContentResponse message includes the specified content(s) as mime multipart attachment(s) within the message. 3993 3994 If there are errors encountered, the RegistryResponse payload includes the errors and there are no additional mime multipart attachments. 3995 8.4.1 Identification Of Content Payloads 3996 3997 3998 Since the GetContentResponse message may include several repository items as additional payloads, it is necessary to have a way to identify each mime multipart attachment in the message. To facilitate this identification, the Registry must do the following: SELECT id From ExternalLink WHERE id IN (RegistryObject_externalLinks(<id>)) SELECT id From ExtrinsicObject WHERE id IN (RegistryObject_linkedObjects(<id>)) SELECT id FROM ExternalLink WHERE id IN (RegistryObject_externalLinks(<id>)) AND description LIKE ‘%legal%’ AND externalURI LIKE ‘%http://%’ SELECT id FROM AuditableEvent WHERE Copyright © OASIS, 2002.

All Rights Reserved Page 113 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 4100 9 Content Management Services 4101 Fix pictures, schema for index to catalog name change?? 4102 4103 4104 4105 This chapter describes the Content-based discovery facility of the ebXML Registry. This facility enables clients to discover repository items based upon the content contained within the repository item. The Content-based discovery facility is a required normative feature of ebXML Registries compliant to version 3 or later of this specification. 4106 4107 4108 4109 4110 4111 4112 The essence of the content-based discovery feature is based upon the ability to selectively convert repository item content into metadata consisting of instances of RegistryObject subclasses (RegistryObject Metadata). A registry uses one or more Content Cataloguing Services to automatically catalog repository items. Cataloguing a repository item creates and/or updates RegistryObject metadata such as ExtrinsicObject or Classification instances. The catalogued metadata enables clients to discover the repository item using existing query capabilities of the registry. 4113 9.1 Content Cataloging: Use Cases 4114 There are many scenarios where content-based discovery is necessary. 4115 9.1.1 Find All CPPs Where Role is “Buyer” 4116 4117 A company that sells a product using the RosettaNet PIP3A4 Purchase Order process wants to find CPPs for other companies where the Role element of the CPP is that of “Buyer”. 4118 9.1.2 Find All XML Schema’s That Use Specified Namespace 4119 4120 A client may wish to discover all XML Schema documents in the registry that use an XML namespace containing the word “oasis”. 4121 9.1.3 Find All WSDL Descriptions with a SOAP Binding 4122 4123 4124 An ebXML registry client is attempting to discover all repository items that are WSDL descriptions that have a SOAP binding defined. Note that SOAP binding related information is content within the WSDL document and not metadata. 4125 9.2 Content Cataloguing Service 4126 4127 4128 4129 4130 4131 Figure 38 shows that conceptually, a Content Cataloguing Service (or Cataloguing Service) accepts as input a repository item and generates as output one or more RegistryObject Metadata instances that are used to catalog the ExtrinsicObject for that repository item. In addition a Cataloging Service accepts as control input a Catalog Definition File, which is also a repository item. Copyright © OASIS, 2002.

The Content Cataloguing Service is the normative Default XML Cataloguing Service described in section 9.10. o In the center we see a Content Cataloguing Service name defaultXMLCataloging Service. o On the left we see a CPP repository item and its ExtrinsicObject inputExtObjForCPP being input as Content to the defaultXMLCataloging Service. o On top we see an XSLT style sheet repository item and its ExtrinsicObject being sent as a Catalog Definition File to the defaultXMLCataloging Service. o On the right we see the outputExtObjForCPP, which is the modified ExtrinsicObject for the CPP. We also see a Classification roleClassification, which classifies the CPP by the Role element within the CPP. These are the Catalog Metadata generated as a result of the Cataloging Service cataloguing the CPP. Copyright © OASIS, 2002.

This specification does not define the format of the Catalog Definition File. Each Cataloging Service is free to define its own Catalog Definition File format in a Cataloging Service specific manner. The only constraint in this specification is that the Catalog Definition File must be a repository item. 4156 9.4 Content To Be Cataloged 4157 4158 4159 4160 4161 4162 4163 4164 4165 4166 4167 This specification does not define the format of content to be Cataloged. This specification describes how a client may register arbitrary Cataloging Services for cataloguing arbitrary content types. The most common use case for a Cataloging Service is for cataloguing XML documents. Therefore, this specification also provides a normative definition for a specialized XML Content Cataloging Service in section 9.10. An ebXML Registry must provide native built-in support for the normative default XML Content Cataloging Service. In addition, an ebXML Registry may optionally allow clients to register arbitrary Cataloging Services for arbitrary content. In either case the registry must use the appropriate Cataloging Service if one exists, to catalog a repository item when it is submitted. Copyright © OASIS, 2002.

The content cataloguing service must map the extracted content to catalog metadata in form of instances of RIM classes. For example, the catalog metadata may consists of: o Classification instances o ExternalIdentifier instances o ExternalLink instances o The name attribute for the ExtrinsicObject for the content to be Cataloged o The description attribute for the ExtrinsicObject for the content to be Cataloged A Content Cataloguing Service may generate any class defined by RIM as catalog metadata in an application specific manner. 4180 9.6 Content Cataloguing Protocol 4181 4182 4183 4184 4185 4186 4187 4188 The interface of the Content Cataloguing Service must implement a single method called catalogContent. The catalogContent method accepts a CatalogContentRequest as parameter and returns a CatalogContentResponse as its response if there are no errors. The CatalogContentRequest contains repository items that need to be catalogued. The resulting CatalogContentResponse contains the metadata that gets generated by the Content Cataloguing Service as a result of cataloguing the specified repository items. The content cataloguing protocol is abstract and does not specify the implementation details of any specific Content Cataloguing Service. 4189 4190 Figure 40: Content Cataloging Protocol 4191 9.6.1 CatalogContentRequest 4192 4193 The CatalogContentRequest is used to pass repository items to a Content Cataloguing Service so that it can create catalog metadata for the specified repository items.

It may include a modified ExtrinsicObject for the repository item that has been catalogued by the Content Cataloguing Service. The Content Cataloguing Service may add metadata such as Classifications, ExternalIdentifiers, name, description etc. to the CataloguedExtrinsicObject element. There must not be an accompanying repository item as an attachment to this response message. 4239 4240 9.7 Publishing a Content Cataloguing Service 4241 4242 4243 4244 4245 4246 4247 4248 4249 4250 4251 4252 4253 4254 4255 4256 4257 4258 4259 4260 4261 4262 Any publisher may publish an arbitrary Content Cataloguing Service to an ebXML Registry. The Content Cataloguing Service must be published using the existing LifeCycleManager interface. The publisher must use the existing SubmitObjectsRequest to publish: o A Service instance that must have a required Association with associationType of “CataloguingServiceFor”. In Figure 43 this is exemplified by the defaultXMLCatalogingService in the upper-left corner. The Service must be the sourceObject while a ClassificationNode in the canonical ObjectType ClassificationScheme must be the targetObject. o A ServiceBinding instance contained within the Service instance that must provide the accessURI to the Cataloguing Service. o An optional ExternalLink instance on the ServiceBinding that is resolvable to a web page describing: o The format of the supported content to be Cataloged o The format of the supported Catalog Definition File Note that no SpecificationLink is required since this specification is implicit for Content Cataloguing Services. o One or more Catalog Definition File(s) that must be an ExtrinsicObject and a repository item pair. The ExtrinsicObject for the Catalog Definition must have a required Association with associationType of “CatalogedefinitionFileFor”. In Figure 43 this is exemplified by the cppCatalogingServiceXSLT and the oagBODCatalogingServiceXSLT objects on the left side. The Service must be the sourceObject while a ClassificationNode in the canonical ObjectType ClassificationScheme must be the targetObject. Copyright © OASIS, 2002.

This Cataloging Service may be used with any XML content that has its objectType attribute reference the xmlObjectType ClassificationNode or one of its descendents. The figure also shows two different Catalog Definition Files, cppCataloging ServiceXSLT and oagBODCataloging ServiceXSLT that may be used to catalog ebXML CPP and OAG Business Object Documents (BOD) respectively. 4276 9.7.1 Multiple Cataloging Services and Catalog Definition Files 4277 4278 4279 4280 4281 4282 4283 4284 4285 4286 May need to change to allow multiple services to be invoked for generic Processing Service?? Vailidation service should be run before cataloguing, catloging before any other?? ValidationServiceFor, CatalogingServiceFor, XXXServiceFor asociationType?? This specification allows clients to submit multiple Cataloging Services and Catalog Definition Files for the same objectType. How a registry handles multiple Cataloging Service and Catalog Definition File submission for the same type of content is a matter of registry specific policy. If a registry does not allow this then it must send an InvalidRequestException with a reason, when a duplicate Cataloging Service or Catalog Definition File is submitted. If a registry allows this then it must provide a conflict resolution mechanism to select the appropriate Cataloging Service and Catalog Definition File in some registry specific manner.

A registry may use registry specific policies to determine whether a client submitted Content Cataloguing Service or Catalog Definition File are acceptable. For example a registry may require that the content cataloguing service or Catalog Definition File does not create excessive metadata. A registry may reject a SubmitObjectRequest with an InvalidRequestException and give a reason why the request was rejected, upon receiving requests publishing Content Cataloguing Service or Catalog Definition File that is unreasonable. In effect support for user-defined Content Cataloguing Services is optional in this version of the specification. 4296 9.8 Dynamic Content Cataloguing 4297 4298 4299 4300 4301 4302 4303 4304 4305 4306 4307 4308 4309 4310 4311 4312 4313 4314 4315 Some time during or after a publisher submits a repository item, the registry must check to see if there is a Content Cataloguing Service and Catalog Definition File registered for that type of repository item. This is referred to as Content Cataloguing Service resolution and Catalog Definition File resolution as described in section 9.8.2. If a Content Cataloguing Service and Catalog Definition File are found then the registry must invoke that service using the Content Cataloguing Protocol. In the invocation, it gives a repository item as content to be Cataloged and a repository item as Catalog Definition File within a CatalogContentRequest. The Content Cataloguing Service must catalog the content and return the potentially modified ExtrinsicObject for the content to be Cataloged such that it has catalog metadata generated from relevant portions of the content to be Cataloged. The registry must store the repository item along with the potentially modified ExtrinsicObject annotated with the catalog metadata once the Content Cataloguing Protocol is completed. The result of dynamic Content Cataloguing is that content to be Cataloged gets catalogued automatically as a consequence of being submitted. Once catalogued it is possible to use the catalog metadata to do dynamic content-based discovery of the Cataloged content. A registry may do dynamic content cataloguing synchronous with the original SubmitObjectRequest request or it may do so asynchronously sometime after the request is committed. A registry must declare the maximum latency between content submission and content Cataloging in the catalogingLatency attribute of its Registry instance. 4316 9.8.1 Referential Integrity and Dynamic Content Cataloguing 4317 4318 A registry must maintain referential integrity between the RegistryObjects and repository items in the submission and the generated RegistryObjects in the catalogued metadata. 4319 9.8.2 Error Handling Model for Dynamic Content Cataloguing 4320 4321 4322 4323 4324 4325 4326 Any errors generated during dynamic content cataloguing must not affect the storing of the RegistryObjects and repository items that were submitted. Such cataloguing errors are internal registry errors due to implementation errors or configuration errors. A registry must return a normal response with status = “Success” if the submitted content and metadata is stored successfully even when there are errors encountered during dynamic content cataloguing. A registry should log such cataloguing errors like any other internal registry errors so that a Registry Operator may be able to explore the problem at a later time. Copyright © OASIS, 2002.

Get the objectType attribute of the ExtrinsicObject. If the objectType is a UUID to a classificationNode (refered to as objectType ClassificationNode) then proceed to next step. Need to update objectType in ebRIM to say it must be a ref to a node in ObjectType. For backward compatibility allow non-UUID values. If not UUID to Cnode then return with no service/CDF resolution?? 4339 4340 4341 4342 4343 2. Query to see if the objectType ClassificationNode is the targetObject of an Association with associationType of CataloguingServiceFor. If desired Association is not found for this ClassificationNode then repeat this step with its parent ClassificationNode. Repeat until the desired Association is found or until the parent is the ClassificationScheme. If desired Association is found proceed to next step. 4344 4345 4346 3. Check if the sourceObject of the desired Association is a Service instance. If not, log an InvalidRequestException. If it is a Service instance, then use this Service as the content cataloguing service for the ExtrinsicObject. 4347 4348 4349 4350 4351 4. Query to see if the objectType ClassificationNode is the targetObject of an Association with associationType of CatalogDefinitionFileFor. If desired Association is not found for this ClassificationNode then repeat this step with its parent ClassificationNode. Repeat until the desired Association is found or until the parent is the ClassificationScheme. If desired Association is found proceed to next step. 4352 4353 4354 5. Check if the sourceObject of the desired Association is an ExtrinsicObject instance. If not, log an InvalidRequestException. If it is an ExtrinsicObject instance, then use its repository item as the Catalog Definition File. 4355 4356 4357 4358 4359 The above algorithm allows for objectType hierarchy to be used to configure Cataloging Service and Catalog Definition Files with varying degrees of specificity or specialization with respect to the type of content. If no Cataloging Service or Catalog Definition File is found then content should not be catalogued. 4360 9.9 Dynamic Content-based Discovery 4361 4362 4363 4364 As described earlier, content to be Cataloged is automatically catalogued when it is submitted to the registry. This content may subsequently be dynamically discovered using the catalog metadata within existing AdhocQueryRequest. Because the catalog metadata is based upon content to be Cataloged, an AdhocQueryRequest can perform dynamic content- based discovery. Copyright © OASIS, 2002.

The XML content cataloguing service accepts an XML instance document as its input and it accepts an XSLT Style sheet as a Content Definition File. Each type of content should have its own unique XSLT style sheet. For example, an ebXML CPP document should have a specialized ebXML CPP catalog definition style sheet. The XML content cataloguing service must apply the XSLT style sheet to the XML instance document input to generate the catalog metadata. Since a single style sheet must be applied to both the ExtrinsicObject and the content to be Cataloged , we must assume the two documents to be composed within a single virtual document the schema for which is as follows: 4380 9.10.1 Publishing of Default XML Content Cataloging Service 4381 4382 4383 4384 The default XML Content Cataloguing Service need not be explicitly published to an ebXML Registry. An ebXML Registry must provide the XML Content Cataloguing Service natively as a built-in service. This built-in service must be published to the registry as part of the intrinsic bootstrapping of required data within the registry. 4385 9.11 Canonical Catalog Definition Files 4386 4387 4388 4389 4390 4391 It is desirable to have identical Catalog Definition Files and cataloguing services for a given object type across all registry implementations. This provides a consistent behavior for dynamic content cataloguing across registries. To facilitate consistency a non-normative set of canonical Catalog Definition Files will be maintained at: http://www.oasis-open.org/committees/regrep/documents/3.0/contentBasedDiscovery It is recommended that producers of content definition files should register them with this site. <cbd:MetaDataAndContent> <rim:ExtrinsicObject/> <someXMLTag/> </cbd:MetaDataAndContent> Copyright © OASIS, 2002. All Rights Reserved Page 123 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 4392 10 Event Notification 4393 4394 4395 4396 4397 4398 4399 4400 4401 4402 This chapter defines the Event Notification feature of the OASIS ebXML Registry. The Event Notification feature is an optional but normative feature of the ebXML Registry. Event Notification feature allows OASIS ebXML Registries to notify its users and / or other registries about events of interest. It allows users to stay informed about registry events without being forced to periodically poll the registry. It also allows a registry to propagate internal changes to other registries whose content might be affected by those changes. ebXML registries support content-based Notification where interested parties express their interest in form of a query. This is different from subject–based (sometimes referred to as topicbased) notification, where information is categorized by subjects and interested parties express their interests in those predefined subjects. 4403 10.1 Use Cases 4404 4405 The following use cases illustrate different ways in which ebXML registries notify users or other registries. 4406 10.1.1 New Service is Offered 4407 4408 4409 A user wishes to know when a new Plumbing service is offered in her town. When that happens, she might try to learn more about that service and compare it with her current Plumbing service provider’s offering. 4410 10.1.2 Monitor Download of Content 4411 4412 4413 User wishes to know whenever her CPP [ebCPP] is downloaded in order to evaluate on an ongoing basis the success of her recent advertising campaign. She might also want to analyze who the interested parties are. 4414 10.1.3 Monitor Price Changes 4415 4416 4417 User wishes to know when the price of a product that she is interested in buying drops below a certain amount. If she buys it she would also like to be notified when the product has been shipped to her. 4418 10.1.4 Keep Replicas Consistent With Source Object 4419 4420 4421 4422 In order to improve performance and availability of accessing some registry objects, a local registry may make replicas of certain objects that are hosted by another registry. The registry would like to be notified when the source object for a replica is updated so that it can synchronize the replica with the latest state of the source object. 4423 10.2 Registry Events 4424 4425 4426 4427 4428 Activities within a registry result in meaningful events. Typically, registry events are generated when a registry processes client requests. In addition, certain registry events may be caused by administrative actions performed by a registry operator. [ebRIM] defines the AuditableEvent class, instances of which represent registry events. When such an event occurs, an AuditableEvent instance is generated by the registry. Copyright © OASIS, 2002. All Rights Reserved Page 124 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 4429 10.3 Subscribing to Events 4430 4431 4432 4433 A User may create a subscription with a registry if she wishes to receive notification for a specific type of event. A User creates a subscription by submitting a Subscription instance to a registry using the SubmitObjectsRequest. If a Subscription is submitted to a registry that does not support event notification then the registry must return an UnsupportedCapabilityException. 4434 10.3.1 Event Selection 4435 4436 4437 4438 In order for a User to only be notified of specific events of interest, she must specify a Selector within the Subscription instance. Each Selector contains a query that determines whether an event qualifies for that Subscription or not. The query syntax is the standard ad hoc query syntax described in chapter 8. Need examples of Subscriptions, Notifications?? 4439 10.3.2 Notification Action 4440 4441 4442 4443 4444 4445 4446 4447 4448 4449 4450 4451 Editor wordsmith?? When creating a Subscription, a User may also specify what the registry should do when an event matching the Selector for that Subscription (subscription event) transpires. A User may specify Actions within the Subscription. Each Action defines an action that the registry must perform when a subscription event transpires. If no Actions are defined within the Subscription that implies that the user does not wish to be notified asynchronously by the registry and instead intends to periodically poll the registry and pull the pending Notifications. [ebRIM] defines two standard Actions that allow delivery of event notifications via email to a human user or by invocation of a web service based programmatic interface. For each event that transpires in the registry, if the registry supports event notification, it must check all registered and active Subscriptions and see if any Subscriptions match the event. If a match is found then the registry performs the Notification Actions required for the Subscription. 4452 10.3.3 Subscription Authorization 4453 4454 4455 A registry may use registry specific policies to decide which User is authorized to create a subscription and to what events. A Registry must return an AuthorizationException in the event that an Unauthorized User submits a Subscription to a registry. 4456 10.3.4 Subscription Quotas 4457 4458 4459 4460 4461 4462 See if we can wordsmith to avoid using number as the limit. What if few heavy duty subscriptions?? A registry may use registry specific policies to decide an upper limit on the number of Subscriptions a User is allowed to create. A Registry must return a QuotaExceededException in the event that an Authorized User submits more Subscriptions than allowed by their registry specific quota. Copyright © OASIS, 2002. All Rights Reserved Page 125 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 4463 10.3.5 Subscription Expiration 4464 4465 4466 4467 4468 4469 4470 Each subscription defines a startDate and and endDate attribute which determines the period within which a Subscription is active. Outside the bounds of the active period, a Subsription may exist in an expired state within the registry. A registry may remove an expired Subscription at any time. In such cases the identity of a RegistryOperator User must be used for the request in order to have sufficient authorization to remove a User’s Subscription. A Registry must not consider expired Subscriptions when delivering notifications for an event to its Subscriptions. An expired Subscription may be renewed by submitting a new Subscription. 4471 10.4 Unsubscribing from Events 4472 4473 4474 4475 A User may terminate a Subscription with a registry if she no longer wishes to be notified of events related to that Subscription. A User terminates a Subscription by deleting the corresponding Subscription object using the RemoveObjectsRequest to the registry. Removal of a Subscription object follows the same rules as removal of any other object. 4476 10.5 Notification of Events 4477 4478 4479 4480 4481 4482 4483 4484 4485 A registry performs the Actions for a Subscription in order to actually deliver the events. However, regardless of the specific delivery action, the registry must communicate the Subscription events. The Subscription events are delivered within a Notification instance as described by [ebRIM]. [ebRIM] defines an extensible description of Notifications, making it possible to allow for registry or application specific Notifications. It defines several normative types of Notifications. A client may specify the type of Notification they wish to receive using the notificationOption attribute of the Action within the Subscription. The registry may override this notificationOption based upon registry specific operational policies. 4486 10.6 Retrieval of Events 4487 4488 4489 The registry provides asynchronous PUSH style delivery of Notifications via notify Actions as described earlier. However, a client may also use a PULL style to retrieve any pending events for their Subscriptions. Pulling of events is done using the Get Notifications protocol. 4490 10.6.1 GetNotificationsRequest 4491 4492 The GetNotificationsRequest is used by a client to retrieve any pending events for their Subscriptions. 4493 10.6.1.1 Syntax: 4494 4495 Figure 44: GetNotificationsRequest Syntax Copyright © OASIS, 2002. All Rights Reserved Page 126 of 167 OASIS/ebXML Registry Services Specification v2.0 4496 4497 4498 March 2016 10.6.1.2 Parameters: subscriptionRefs: This parameter specifies a collection of ObjectRefs to Subscription objects for which the client wishes to get Notifications. 4499 4500 10.6.1.3 Returns: 4501 This request returns a GetNotificationsResponse. See section 10.6.2 for details. 4502 10.6.1.4 Exceptions: 4503 In addition to the exceptions common to all requests, the following exceptions may be returned: 4504 4505 ObjectNotFoundException: signifies that a specified Subscription was not found in the registry. 4506 10.6.2 GetNotificationsResponse 4507 4508 The GetNotificationsResponse is sent by the registry as a response to GetNotificationsRequest. It contains the Notifications for the Subscription specified in the GetNotificationsRequest. 4509 4510 10.6.2.1 Syntax: 4511 4512 4513 4514 4515 4516 4517 Figure 45: GetNotificationsResponse Syntax 10.6.2.2 Parameters: notification: This parameter specifies a notification contained within the GetNotificationsResponse. The notification is actually delivered as a more specialized sub-type (e.g. EventRefsNotification) as defined by [ebRIM]. 4518 10.7 Purging of Events 4519 4520 4521 A registry may periodically purge AuditableEvents in order to manage its resources. It is up to the registry when such purging occurs. It is up to the registry to determine when undelivered events are purged. Copyright © OASIS, 2002. All Rights Reserved Page 127 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 4522 11 Cooperating Registries Support 4523 4524 This chapter describes the capabilities and protocols that enable multiple ebXML registries to cooperate with each other to meet advanced use cases. 4525 11.1 Cooperating Registries Use Cases 4526 4527 The following is a list of use cases that illustrate different ways that ebXML registries cooperate with each other. 4528 11.1.1 Inter-registry Object References 4529 4530 4531 4532 A Submitting Organization wishes to submit a RegistryObject to a registry such that the submitted object references a RegistryObject in another registry. An example might be where a RegistryObject in one registry is associated with a RegistryObject in another registry. 4533 4534 Figure 46: Inter-registry Object References 4535 4536 11.1.2 Federated Queries 4537 4538 4539 4540 A client wishes to issue a single query against multiple registries and get back a single response that contains results based on all the data contained in all the registries. From the client’s perspective it is issuing its query against a single logical registry that has the union of all data within all the physical registries. 4541 11.1.3 Local Caching of Data from Another Registry 4542 4543 4544 4545 4546 4547 4548 4549 A destination registry wishes to cache some or all the data of another source registry that is willing to share its data. The shared dataset is copied from the source registry to the destination registry and is visible to queries on the destination registry even when the source registry is not available. Local caching of data may be desirable in order to improve performance and availability of accessing that object. An example might be where a RegistryObject in one registry is associated with a RegistryObject in another registry, and the first registry caches the second RegistryObject locally.

All Rights Reserved Page 128 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 4550 11.1.4 Object Relocation 4551 4552 A Submitting Organization wishes to relocate its RegistryObjects and/or repository items from the registry where it was submitted to another registry. 4553 11.2 Registry Federations 4554 4555 4556 4557 A registry federation is a group of registries that have voluntarily agreed to form a loosely coupled union. Such a federation may be based on common business interests and specialties that the registries may share. Registry federations appear as a single logical registry, to registry clients. 4558 4559 Figure 47: Registry Federations 4560 4561 4562 4563 4564 4565 4566 4567 Registry federations are based on a peer-to-peer (P2P) model where all participating registries are equal. Each participating registry is called a registry peer. There is no distinction between the registry operator that created a federation and those registry operators that joined that Federation later. Any registry operator may form a registry federation at any time. When a federation is created it must have exactly one registry peer which is the registry operated by the registry operator that created the federation. Any registry may choose to voluntarily join or leave a federation at any time. 4568 11.2.1 Federation Metadata 4569 4570 4571 4572 4573 4574 4575 The Registry Information model defines the Registry and Federation classes, instances of these classes and the associations between these instances describe a federation and its members. Such instance data is referred to as Federation Metadata. The Registry and Federation classes are described in detail in [ebRIM]. The Federation information model is summarized here as follows: o A Federation instance represents a registry federation. o A Registry instance represents a registry that is a member of the Federation. Copyright © OASIS, 2002. All Rights Reserved Page 129 of 167 OASIS/ebXML Registry Services Specification v2.0 4576 4577 4578 4579 March 2016 o An Association instance with associationType of HasFederationMember represents membership of the registry in the federation. This Association links the Registry instance and the Federation instance. 4580 4581 Figure 48: Federation Metadata Example 4582 11.2.2 Local Vs. Federated Queries 4583 4584 4585 4586 A federation appears to registry clients as a single unified logical registry. An AdhocQueryRequest sent by a client to a federation member may be local or federated. A new boolean attribute named federated is added to AdhocQueryRequest to indicate whether the query is federated or not. 4587 11.2.2.1 Local Queries 4588 4589 4590 4591 When the federated attribute of AdhocQueryRequest has the value of false then the query is a local query. In the absence of a federated attribute the default value of federated attribute is false. A local AdhocQueryRequest is only processed by the registry that receives the request. A local AdhocQueryRequest does not operate on data that belongs to other registries. 4592 11.2.2.2 Federated Queries 4593 4594 4595 4596 4597 4598 4599 When the federated attribute of AdhocQueryRequest has the value of true then the query is a federated query. A federated query to any federation member must be routed by that member to all other federation member registries as parallel-distributed queries. A federated query operates on data that belongs to all members of the federation. When a client submits a federated query to a registry that is not a member of a federation, the registry must treat it as a local query. Copyright © OASIS, 2002. All Rights Reserved Page 130 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 4600 11.2.2.3 Membership in Multiple Federations 4601 4602 4603 4604 4605 4606 A registry may be a member of multiple federations. In such cases if the federated attribute of AdhocQueryRequest has the value of true then the registry must route the federated query to all federations that it is a member of. Alternatively, the client may specify the id of a specific federation that the registry is a member of, as the value of the federation parameter. The type of the federation parameter is ID. In such cases the registry must route the federated query to the specified federation only. 4607 11.2.3 Federated Lifecycle Management Operations 4608 4609 4610 4611 4612 Details on how to create and delete federations and how to join and leave a federation are described in 11.2.8. All lifecycle operations must be performed on a RegistryObject within its home registry using the operations defined by the LifeCycleManager interface. Unlike query requests, lifecycle management requests do not support any federated capabilities. 4613 11.2.4 Federations and Local Caching of Remote Data 4614 4615 4616 4617 4618 4619 4620 4621 A federation member is not required to maintain a local cache of replicas of RegistryObjects and repository items that belong to other members of the federation. A registry may choose to locally cache some or all data from any other registry whether that registry is a federation member or not. Data caching is orthogonal to registry federation and is described in section 11.3. Since by default there is minimal replication in the members of a federation, the federation architecture scales well with respect to memory and disk utilization at each registry. Data replication is often necessary for performance, scalability and fault-tolerance reasons. 4622 11.2.5 Caching of Federation Metadata 4623 4624 4625 4626 4627 4628 4629 4630 4631 4632 4633 A special case for local caching is the caching of the Federation and Registry instances and related Associations that define a federation and its members. Such data is referred to as federation metadata. A federation member is required to locally cache the federation metadata, from the federation home for each federation that it is a member of. The reason for this requirement is consistent with a Peer-to-Peer (P2P) model and ensures fault –tolerance in case the Federation home registry is unavailable. The federation member must keep the cached federation metadata synchronized with the master copy in the Federation home, within the time period specified by the replicationSyncLatency attribute of the Federation. Synchronization of cached Federation metadata may be done via synchronous polling or asynchronous event notification using the event notification feature of the registry. 4634 11.2.6 Time Synchronization Between Registry Peers 4635 4636 4637 4638 Federation members are not required to synchronize their system clocks with each other. However, it is recommended that a Federation member keep its clock synchronized with an atomic clock server within the latency described by the replicationSyncLatency attribute of the Federation.

All Rights Reserved Page 131 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 4639 11.2.7 Federations and Security 4640 4641 Federation lifecycle management operations abide by the same security rules as standard lifecycle management. 4642 11.2.8 Federation Lifecycle Management Protocols 4643 4644 4645 This section describes the various operations that manage the lifecycle of a federation and its membership. A key design objective is to allow federation lifecycle operations to be done using existing LifeCycleManager interface of the registry in a stylized manner. 4646 11.2.8.1 Joining a Federation 4647 4648 4649 4650 4651 4652 4653 4654 4655 4656 4657 The following rules govern how a registry joins a federation: Each registry must have exactly one Registry instance within that registry for which it is a home. The Registry instance is owned by the RegistryOperator and may be placed in the registry using any operator specific means. The Registry instance must never change its home registry. A registry may request to join an existing federation by submitting an instance of an Extramural Association that associates the Federation instance as sourceObject, to its Registry instance as targetObject, using an associationType of HasFederationMember. The home registry for the Association and the Federation objects must be the same. The owner of the Federation instance must confirm the Extramural Association in order for the registry to be accepted as a member of the federation. 4658 11.2.8.2 Creating a Federation 4659 4660 4661 4662 4663 4664 The following rules govern how a federation is created: A Federation is created by submitting a Federation instance to a registry using SubmitObjectsRequest. The registry where the Federation is submitted is referred to as the federation home. The federation home may or may not be a member of that Federation. A federation home may contain multiple Federation instances. 4665 11.2.8.3 Leaving a Federation 4666 4667 4668 4669 The following rules govern how a registry leaves a federation: A registry may leave a federation at any time by removing its HasFederationMember Association instance that links it with the Federation instance. This is done using the standard RemoveObjectsRequest. 4670 11.2.8.4 Dissolving a Federation 4671 4672 4673 4674 4675 The following rules govern how a federation is dissolved: A federation is dissolved by sending a RemoveObjectsRequest to its home registry and removing its Federation instance. The removal of a Federation instance is controlled by the same Access Control Policies that govern any RegistryObject. Copyright © OASIS, 2002. All Rights Reserved Page 132 of 167 OASIS/ebXML Registry Services Specification v2.0 4676 4677 4678 4679 4680 March 2016 The removal of a Federation instance is controlled by the same lifecycle management rules that govern any RegistryObject. Typically, this means that a federation may not be dissolved while it has federation members. It may however be deprecated at any time. Once a Federation is deprecated no new members can join it. 4681 11.3 Object Replication 4682 4683 4684 4685 4686 4687 4688 4689 RegistryObjects within a registry may be replicated in another registry. A replicated copy of a remote object is referred to as its replica. The remote object may be an original object or it may be a replica. A replica from an original is referred to as a first-generation replica. A replica of a replica is referred to as a second-generation replica (and so on). The registry that replicates a remote object locally is referred to as the destination registry for the replication. The registry that contains the remote object being replicated is referred to as the source registry for the replication. 4690 4691 Figure 49: Object Replication 4692 4693 11.3.1 Use Cases for Object Replication 4694 4695 A registry may create a local replica of a remote object for a variety of reasons. A few sample use cases follow: 4696 4697 4698 4699 4700 4701 4702 o Improve access time and fault tolerance via locally caching remote objects. For example, a registry may automatically create a local replica when a remote ObjectRef is submitted to the registry. o Improve scalability by distributing access to hotly contested object, such as NAICS scheme, across multiple replicas. o Enable cooperating registry features such as hierarchical registry topology and local caching of federation metadata.

Local replicas are considered within the extent of the data set of a registry as far as local queries are concerned. When a client submits a local query that retrieves a remote object by its id attribute, if the registry contains a local replica of that object then the registry should return the state defined by the local replica. 4710 11.3.3 Lifecycle Operations And Replicas 4711 4712 4713 LifeCycle operations on an original object must be performed at the home registry for that object. LifeCycle operations on replicas of an original object only affect the replica and do not have any impact on the original object. 4714 11.3.4 Object Replication and Federated Registries 4715 4716 4717 Object replication capability is orthogonal to the registry federation capability. Objects may be replicated from any registry to any other registry without any requirement that the registries belong to the same federation. 4718 11.3.5 Creating a Local Replica 4719 4720 4721 4722 4723 4724 4725 4726 4727 4728 4729 4730 4731 4732 Any Submitting Organization can create a replica by using the existing SubmitObjectsRequest. If a registry receives a SubmitObjectRequest which has an RegistryObjectList containing a remote ObjectRef, then it must create a replica for that remote ObjectRef. In addition to Submitting Organizations, a registry itself may create a replica under specific situations in a registry specific manner. Creating a local replica requires the destination registry to read the state of the remote object from the source registry and then create a local replica of the remote object. A registry may use standard QueryManager interface to read the state of a remote object (whether it is an original or a replica). No new APIs are needed to read the state of a remote object. Since query functionality does not need prior registration, no prior registration or contract is needed for a registry to read the state of a remote object. Once the state of the remote object has been read, a registry may use registry specific means to create a local replica of the remote object. Such registry specific means may include the use of the LifeCycleManager interface. 4733 4734 A replica of a RegistryObject may be distinguished from an original since a replica must have its home attribute point to the remote registry where the original for the replica resides. 4735 11.3.6 Transactional Replication 4736 4737 4738 4739 4740 4741 Transactional replication enables a registry to replicate events in another registry in a transactionally consistent manner. This is typically the case when entire registries are replicated to another registry. This specification defines a more loosely coupled replication model as an alternative to transactional replication for the following reasons: Transactional replication is not a typical use case for registries Copyright © OASIS, 2002. All Rights Reserved Page 134 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 4742 4743 4744 4745 4746 4747 4748 Registry implementations are not required to implement transactional replication. 4749 11.3.7 Keeping Replicas Current 4750 4751 4752 4753 4754 A registry must keep its replicas current within the latency specified by the value of the replicationSyncLatency attribute defined by the registry. This includes removal of the replica when its original is removed from its home registry. Replicas may be kept current using the event notification feature of the registry or via periodic polling. 4755 11.3.8 Write Operations on Local Replica 4756 4757 4758 Local Replicas are read-only objects. Lifecycle management operations of RegistryObjects are not permitted on local replicas. All lifecycle management operation to RegistryObjects must be performed in the home registry for the object. 4759 11.3.9 Tracking Location of a Replica 4760 4761 4762 4763 4764 A local replica of a remote RegistryObject instance must have exactly one ObjectRef instance within the local registry. The home attribute of the ObjectRef associated with the replica tracks its home location. A RegistryObject must have exactly one home. The home for a RegistryObject may change via Object Relocation as described in section 11.4. It is optional for a registry to track location changes for replicas within it. 4765 11.3.10 4766 4767 4768 It is possible to have a remote ObjectRef to a RegistryObject that is a replica of another RegistryObject. In such cases the home attribute of the ObjectRef contains the base URI to the home registry for the replica. 4769 11.3.11 4770 4771 4772 A Submitting Organization can remove a replica by using the RemoveObjectsRequest. If a registry receives a RemoveObjectsRequest that has an ObjectRefList containing a remote ObjectRef, then it must remove the local replica for that remote ObjectRef. 4773 11.4 Object Relocation Protocol 4774 4775 4776 4777 Need to replace this with Registry Import/Export capability?? Every RegistryObject has a home registry and a User within the home registry that is the publisher or owner of that object. Initially, the home registry is the where the object is originally submitted. Initially, the owner is the User that submitted the object. Loosely coupled replication as defined by this specification typically suffices for most use cases Transaction replication is very complex and error prone Transactional replication requires a tight coupling between registries participating in the replication Remote Object References to a Replica Removing a Local Replica Copyright © OASIS, 2002. All Rights Reserved Page 135 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 4778 4779 4780 4781 A RegistryObject may be relocated from one home registry to another home registry using the Object Relocation protocol. Within the Object Relocation protocol, the new home registry is referred to as the destination registry while the previous home registry is called the source registry. 4782 4783 4784 4785 4786 4787 4788 4789 4790 4791 4792 Figure 50: Object Relocation The User at the source registry who owns the objects being relocated is referred to as the ownerAtSource. The User at the destination registry, who is the new oner of the objects, is referred to as the ownerAtDestination. While the ownerAtSource and the ownerAtDestination may often be the same identity, the Object Relocation protocol treats them as two distinct identities. A special case usage of the Object Relocation protocol is to transfer ownership of RegistryObjects from one User to another within the same registry. In such cases the protocol is the same except for the fact that the source and destination registries are the same. Following are some notable points regarding object relocation: 4793 4794 Object relocation does not require that the source and destination registries be in the same federation or that either registry have a prior contract with the other. 4795 4796 4797 4798 4799 4800 4801 4802 4803 4804 4805 Object relocation must preserve object id. While the home registry for a RegistryObject may change due to object relocation, its id never changes. ObjectRelocation must preserve referential integrity of RegistryObjects. Relocated objects that have references to an object that did not get relocated must preserve their reference. Similarly objects that have references to a relocated object must also preserve their reference. Thus, relocating an object may result in making the value of a reference attribute go from being a local reference to being a remote reference or vice versa. AcceptObjectsRequest does not include ObjectRefList. It only includes an opaque transactonId identifying the relocateObjects transaction. The requests defined by the Relocate Objects protocol must be sent to the source or destination registry only. Copyright © OASIS, 2002. All Rights Reserved Page 136 of 167 OASIS/ebXML Registry Services Specification v2.0 4806 4807 4808 4809 4810 4811 4812 4813 4814 4815 March 2016 When an object is relocated an AuditableEvent of type “Relocated” happens. Relocated events must have the source and target registry’s base URIs recorded as two Slots on the Relocated event. The names of these Slots are sourceRegistry and targetRegistry respectively. Figure 51: Relocate Objects Protocol Figure 40 illustrates the Relocate Objects Protocol. The participants in the protocol are the ownerAtSource and ownerAtDestination User instances as well as the LifeCycleManager interfaces of the sourceRegistry and destinationRegistry. The steps in the protocol are described next: 4816 4817 4818 4819 4820 4821 1. The protocol is initiated by the ownerAtSource sending a RelocateObjectsRequest message to the LifeCycleManager interface of the sourceRegistry. The sourceRegistry must make sure that the ownerAtSource is authorized to perform this request. The id of this RelocateObjectsRequest is used as the transaction identifier for this instance of the protocol. This RelocateObjectsRequest message must contain an ObjectRefList element specifying the objects that are to be relocated. 4822 4823 4824 4825 2. Next, the sourceRegistry must send a different RelocateObjectsRequest message to the LifeCycleManager interface of the destinationRegistry. This RelocateObjectsRequest message must not contain the ObjectRefList element. This message signals the detsinationRegistry to participate in relocation protocol. 4826 4827 4828 4829 3. The destinationRegistry must relay the RelocateObjectsRequest message to the ownerAtDestination using the event notification feature of the registry as described in chapter 10. This concludes the sequence of events that were a result of the ownerAtSource sending the RelocateObjectsRequest message to the sourceRegistry. Copyright © OASIS, 2002. All Rights Reserved Page 137 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 4830 4831 4832 4833 4. The ownerAtDestination at a later time may send an AcceptObjectsRequest message to the destinationRegistry. This request must identify the object relocation transaction via the relocateObjectsRequestId. The value of this attribute must be the id of the original RelocateObjectsRequest. 4834 4835 5. The destinationRegistry relays the AcceptObjectsRequest message to the sourceRegistry. The source registry returns the objects being relocated as an AdhocQueryResponse. 4836 4837 4838 6. The registry submits the relocated data to itself assigning the identity of the ownerAtDestination as the owner. The relocated data may be submitted to the destination registry using any registry specific means or a SubmitObjectsRequest. 4839 4840 7. The destinationRegistry notifies the sourceRegistry that the relocated objects have been safely committed. Need to decide on the signal message name here?? 4841 4842 8. The sourceRegistry removes the relocated objects using any registry specific means or a RemoveObjectsRequest. This concludes the Object Relocation transaction. 4843 11.4.1 RelocateObjectsRequest 4844 4845 Figure 52: RelocateObjectsRequest XML Schema 4846 11.4.1.1 Attribute id 4847 The attribute id provides the transaction identifier for this instance of the protocol. 4848 11.4.1.2 Element ObjectRefList 4849 4850 4851 This element specifies the set of id attributes of RegistryObjects that are being relocated. This attribute must be present when the message is sent by the ownerAtSource to the sourceRegistry. This attribute must not be present when the message is sent on any other occasion. 4852 11.4.1.3 Element sourceRegistry 4853 4854 4855 This element specifies the ObjectRef to the sourceRegistry Registry instance. The value of this attribute must be a local reference when the message is sent by the ownerAtSource to the sourceRegistry. Copyright © OASIS, 2002. All Rights Reserved Page 138 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 4856 11.4.1.4 Element destinationRegistry 4857 This element specifies the ObjectRef to the destinationRegistry Registry instance. 4858 11.4.1.5 Element ownerAtSource 4859 This element specifies the ObjectRef to the ownerAtSource User instance. 4860 11.4.1.6 Element ownerAtDestination 4861 This element specifies the ObjectRef to the ownerAtDestination User instance. 4862 11.4.2 AcceptObjectsRequest 4863 4864 11.4.2.1 Attribute relocateObjectsRequestId 4865 4866 The attribute relocateObjectsRequestId provides the transaction identifier for this instance of the protocol. 4867 11.4.3 Object Relocation and Remote ObjectRefs 4868 The following scenario describes what typically happens when a person moves: 4869 4870 4871 4872 4873 4874 4875 4876 4877 4878 4879 1. When a person moves from one house to another, other persons may have their old postal addresses. 2. When a person moves, they leave their new address as the forwarding address with the post office. 3. The post office forwards their mail for some time to their new address. 4. Eventually the forwarding request expires and the post office no longer forwards mail for that person. 5. During this forwarding interval the person notifies interested parties of their change of address. The registry must support a similar model for relocation of RegistryObjects. The following steps describe the expected behavior when an object is relocated. 4880 4881 4882 4883 4884 4885 4886 4887 4888 4889 4890 4891 4892 1. When a RegistryObject O1 is relocated from one registry R1 to another registry R2, other RegistryObjects may have remote ObjectRefs to O1. 2. The registry R1 must leave an AuditableEvent of type Relocated that includes the home URI for the new registry R2. 3. As long as the AuditableEvent exists in R1, if R1 gets a request to retrieve O1 by id, it must forward the request to R2 and transparently retrieve O1 from R2 and deliver it to the client. The object O1 must include the home URI to R2 within the optional home attribute of RegistryObject. Clients are advised to check the home attribute and update the home attribute of their local ObjectRef to match the new home URI value for the object. 4. Eventually the AuditableEvent is cleaned up after a registry specific interval. R1 is no longer required to relay requests for O1 to R2 transparent to the client. Instead R1 must return an ObjectNotFoundException. Copyright © OASIS, 2002. All Rights Reserved Page 139 of 167 OASIS/ebXML Registry Services Specification v2.0 4893 4894 4895 4896 March 2016 5. Clients that are interested in the relocation of O1 and being notified of its new address may choose to be notified by having a prior subscription using the event notification facility of the registry. For example a Registry that has a remote ObjectRefs to O1 may create a subscription on relocation events for O1. This however, is not required behavior. 4897 11.4.4 Notification of Object Relocation 4898 4899 4900 This section describes how the destinationRegistry uses the event notification feature of the registry to notify the ownerAtDestination of a Relocated event. <details TBD> 4901 11.4.5 Object Relocation and Timeouts 4902 4903 4904 No timeouts are specified for the Object Relocation protocol. Registry implementations may cleanup incomplete Object Relocation transactions in a registry specific manner as an administrative task using registry specific policies. Copyright © OASIS, 2002. All Rights Reserved Page 140 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 4905 12 Registry Security 4906 4907 4908 This chapter describes the security features of the ebXML Registry. It is assumed that the reader is familiar with the security related classes in the Registry information model as described in [ebRIM]. Security glossary terms can be referenced from RFC 2828. 4909 12.1 Security Concerns 4910 4911 4912 4913 4914 In the current version of this specification, we address data integrity and source integrity (item 1 in Appendix E.1). We have used a minimalist approach to address the access control concern as in item 2 of Appendix E.1. Essentially, any known entity (Submitting Organization) can publish content and anyone can view published content. The Registry Information Model [ebRIM] is designed to support more sophisticated security policies in future versions of this specification. 4915 12.2 Integrity of Registry Content 4916 4917 4918 4919 4920 4921 4922 4923 4924 It is assumed that most business registries do not have the resources to validate the veracity of the content submitted to them. The mechanisms described in this section can be used to ensure that any tampering with the content can be detected. Furthermore, these mechanisms support unambiguous identification of the Responsible Organization for any registry content. The Registry Client has to sign the contents before submission – otherwise the content will be rejected. Note that in the discussions in this section we assume a Submitting Organization to be also the Responsible Organization. Future versions of this specification may provide more examples and scenarios where a Submitting Organization and Responsible Organization are different. 4925 12.2.1 Message Payload Signature 4926 4927 4928 4929 4930 4931 4932 4933 4934 4935 4936 4937 The integrity of the Registry content requires that all submitted content be signed by the submitter. The signature on the submitted content ensures that: Any tampering of the content can be detected. The content’s veracity can be ascertained by its association with a specific Submitting Organization. This section specifies the requirements for generation, packaging and validation of payload signatures. A payload signature is packaged with the payload. Therefore the requirements apply regardless of whether the Registry Client and the Registration Authority communicate over standard SOAP with Attachments or ebXML Messaging Service [ebMS]. Currently, ebXML Messaging Service does not specify the generation, validation and packaging of payload signatures. The specification of payload signatures is left up to the application (such as Registry). The requirements on the payload signatures augment the [ebMS] specification. 4938 Use Case 4939 4940 4941 4942 This Use Case illustrates the use of header and payload signatures (we discuss header signatures later). RC1 (Registry Client 1) signs the content (generating a payload signature) and publishes the content along with the payload signature to the Registry. Copyright © OASIS, 2002.

The payload signature must be packaged with the payload as specified here. This packaging assumes that the payload is always signed. The payload and its signature must be enclosed in a MIME multipart message with a Content-Type of multipart/related. The first body part must contain the XML signature as specified in Section 12.2.2.2, “Payload Signature Generation Requirements”. The second body part must be the content. 4964 4965 The packaging of the payload signature with two payloads is as shown in the example in Section 8.4.2. 4966 12.2.2.2 Payload Signature Generation Requirements 4967 4968 4969 4970 4971 4972 4973 4974 4975 4976 4977 4978 4979 4980 4981 4982 4983 The ds:Signature element [XMLDSIG] for a payload signature must be generated as specified in this section. Note: the “ds” name space reference is to http://www.w3.org/2000/09/xmldsig# ds:SignatureMethod must be present. [XMLDSIG] requires that the algorithm be identified using the Algorithm attribute. [XMLDSIG] allows more than one Algorithm attribute, and a client may use any of these attributes. However, signing using the following Algorithm attribute: http://www.w3.org/2000/09/xmldsig#dsa-sha1 will allow interoperability with all XMLDSIG compliant implementations, since XMLDSIG requires the implementation of this algorithm. The ds:SignedInfo element must contain a ds:CanonicalizationMethod element. The following Canonicalization algorithm (specified in [XMLDSIG]) must be supported RC2 (Registry Client 2) retrieves RC1’s content from the Registry. RC2 wants to verify that RC1 published the content. In order to do this, when RC2 retrieves the content, the response from the Registration Authority to RC2 contains the following: o Payload containing the content that has been published by RC1. o RC1’s payload signature (represented by a ds:Signature element) over RC1’s published content. o The public key for validating RC1’s payload signature in ds:Signature element ( using the KeyInfo element as specified in [XMLDSIG] ) so RC2 can obtain the public key for signature (e.g. retrieve a certificate containing the public key for RC1). o A ds:Signature element containing the header signature. Note that the Registration Authority (not RC1) generates this signature. http://www.w3.org/TR/2001/REC-xml-c14n-20010315 One ds:Reference element to reference each of the payloads that needs to be signed must be created. The ds:Reference element: o Must identify the payload to be signed using the URI attribute of the ds:Reference element. o Must contain the <ds:DigestMethod> as specified in [XMLDSIG]. A client must support the following digest algorithm: Copyright © OASIS, 2002. All Rights Reserved Page 142 of 167 OASIS/ebXML Registry Services Specification v2.0 4984 4985 March 2016 http://www.w3.org/2000/09/xmldsig#sha1 o Must contain a <ds:DigestValue> which is computed as specified in [XMLDSIG]. 4986 The ds:SignatureValue must be generated as specified in [XMLDSIG]. 4987 4988 The ds:KeyInfo element may be present. However, when present, the ds:KeyInfo field is subject to the requirements stated in Section 12.4, “KeyDistrbution and KeyInfo element”. 4989 12.2.2.3 Message Payload Signature Validation 4990 The ds:Signature element must be validated by the Registry as specified in the [XMLDSIG]. 4991 12.2.2.4 Payload Signature Example 4992 4993 4994 4995 4996 4997 4998 4999 5000 5001 5002 5003 5004 5005 5006 5007 The following example shows the format of the payload signature: 5008 12.3 Authentication 5009 5010 The Registry must be able to authenticate the identity of the Principal associated with client requests and also the owner of each repository item. 5011 5012 5013 5014 5015 5016 5017 The Principal can be identified by verifying the message header signature with the certificate of the Principal. The certificate may be in the message itself or provided to the registry through means unspecified in this specification. If not provided in the message, this specification does not specify how the Registry correlates a specific message with a certificate. Each payload must also be signed to ensure the integrity of that payload and to determine its owner. Authentication is also required to identify the privileges a Principal is authorized to have with respect to specific objects in the Registry. 5018 5019 5020 5021 The Registry must perform authentication on a per message basis. From a security point of view, all messages are independent and there is no concept of a session encompassing multiple messages or conversations. Session support may be added as an optimization feature in future versions of this specification. 5022 5023 5024 It is important to note that the message header signature can only guarantee data integrity. It does not guarantee safety from “replay” attacks. True support for authentication requires timestamps or nonce (nonrecurring series of numbers to identify each message) that are signed. <ds:Signature xmlns:ds="http://www.w3.org/2000/09/xmldsig#"> <ds:SignedInfo> <SignatureMethod Algorithm=”http://www.w3.org/TR/2000/09/xmldsig#dsa-sha1”/> <ds:CanonicalizationMethod> Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315"> </ds:CanonicalizationMethod> <ds:Reference URI=#Payload1> <ds:DigestMethod DigestAlgorithm="http://www.w3.org/TR/2000/09/xmldsig#sha1"> <ds:DigestValue> ... </ds:DigestValue> </ds:Reference> </ds:SignedInfo> <ds:SignatureValue> ... </ds:SignatureValue> </ds:Signature> Copyright © OASIS, 2002.

Note that the signature within the message header also signs the digests of the payloads. 5028 Header Signature Requirements 5029 5030 5031 5032 5033 Message headers may be signed and are referred to as a header signature. When a Registered User sends a request, the Registration Authority may use a pre-established contract or a default policy to determine whether the response should contain a header signature. When a Registry Guest sends a request, the Registration Authority may use a default policy to determine whether the response contains a header signature. 5034 5035 5036 5037 5038 5039 5040 5041 This section specifies the requirements for generation, packaging and validation of a header signature. These requirements apply when the Registry Client and Registration Authority communicate using standard SOAP with Attachments. When ebXML MS is used for communication, then the message handler (i.e. [ebMS]) specifies the generation, packaging and validation of XML signatures in the SOAP header. Therefore the header signature requirements do not apply when the ebXML MS is used for communication. However, payload signature generation requirements (12.2.2.2) do apply whether standard SOAP with Attachments or ebXML MS is used for communication. 5042 12.3.1.1 Packaging Requirements 5043 5044 5045 A header signature is represented by a ds:Signature element. The ds:Signature element generated must be packaged in a <SOAP-ENV:Header> element. The packaging of the ds:Signature element in the SOAP header field is shown in Section 8.4.2. 5046 12.3.1.2 Header Signature Generation Requirements 5047 5048 5049 5050 5051 The ds:Signature element [XMLDSIG] for a header signature must be generated as specified in this section. A ds:Signature element contains: ds:SignedInfo ds:SignatureValue ds:KeyInfo 5052 The ds:SignedInfo element must be generated as follows: 5053 5054 5055 5056 5057 1. ds:SignatureMethod must be present. [XMLDSIG] requires that the algorithm be identified using the Algorithm attribute. While [XMLDSIG] allows more than one Algorithm Attribute, a client must be capable of signing using only the following Algorithm attribute: http://www.w3.org/2000/09/xmldsig#dsa-sha1. All XMLDSIG implementations conforming to the [XMLDSIG] specification support this algorithm. 5058 5059 5060 2. The ds:SignedInfo element must contain a ds:CanonicalizationMethod element. The following Canonicalization algorithm (specified in [XMLDSIG]) must be supported: 5061 5062 5063 5064 3. A ds:Reference element to include the <SOAP-ENV:Envelope> in the signature calculation. This signs the entire ds:Reference element and: o Must include the ds:Transform http://www.w3.org/TR/2001/REC-xml-c14n-20010315 http://www.w3.org/2000/09/xmldsig#enveloped-signature Copyright © OASIS, 2002.

The URI attribute is optional in the [XMLDSIG] specification. The URI attribute must be an empty string (“”). o Must contain the <ds:DigestMethod> as specified in [XMLDSIG]. A client must support the digest algorithm: http://www.w3.org/2000/09/xmldsig#sha1 o Must contain a <ds:DigestValue>, which is computed as specified in [XMLDSIG]. 5073 The ds:SignatureValue must be generated as specified in [XMLDSIG]. 5074 5075 The ds:KeyInfo element may be present. When present, it is subject to the requirements stated in Section 12.4, “KeyDistrbution and KeyInfo element”. 5076 12.3.1.3 Header Signature Validation Requirements 5077 5078 The ds:Signature element for the ebXML message header must be validated by the recipient as specified by [XMLDSIG]. 5079 12.3.1.4 Header Signature Example 5080 5081 5082 5083 5084 5085 5086 5087 5088 5089 5090 5091 5092 5093 5094 5095 5096 5097 5098 The following example shows the format of a header signature: 5099 12.4 Key Distribution and KeyInfo Element 5100 5101 5102 5103 5104 To validate a signature, the recipient of the signature needs the public key corresponding to the signer’s private key. The participants may use the KeyInfo field of ds:Signature, or distribute the public keys in an implementation specific manner. In this section we consider the case when the public key is sent in the KeyInfo field. The following use cases need to be addressed: Registration Authority needs the public key of the Registry Client to validate the signature <ds:Signature xmlns:ds="http://www.w3.org/2000/09/xmldsig#"> <ds:SignedInfo> <SignatureMethod Algorithm=http://www.w3.org/TR/2000/09/xmldsig#dsa-sha1/> <ds:CanonicalizationMethod> Algorithm="http://www.w3.org/TR/2000/CR-xml-c14n-2001026"> </ds:CanonicalizationMethod> <ds:Reference URI= “”> <ds:Transform> http://www.w3.org/2000/09/xmldsig#enveloped-signature </ds:Transform> <ds:DigestMethod DigestAlgorithm="./xmldsig#sha1"> <ds:DigestValue> ... </ds:DigestValue> </ds:Reference> </ds:SignedInfo> <ds:SignatureValue> ... </ds:SignatureValue> </ds:Signature> Copyright © OASIS, 2002.

A Certificate is associated both with the Registration Authority and a Registry Client. 5115 5116 2. A Registry Client registers its certificate with the Registration Authority. The mechanism used for this is not specified here. 5117 5118 3. A Registry Client obtains the Registration Authority’s certificate and stores it in its own local key store. The mechanism is not specified here. 5119 Appendix F.8 contains a few scenarios on the use of KeyInfo field. 5120 12.5 Confidentiality 5121 12.5.1 On-the-wire Message Confidentiality 5122 5123 5124 It is suggested but not required that message payloads exchanged between clients and the Registry be encrypted during transmission. This specification does not specify how payload encryption is to be done. 5125 12.5.2 Confidentiality of Registry Content 5126 5127 5128 5129 In the current version of this specification, there are no provisions for confidentiality of Registry content. All content submitted to the Registry may be discovered and read by any client. This implies that the Registry and the client need to have an a priori agreement regarding encryption algorithm, key exchange agreements, etc. 5130 12.6 Authorization 5131 5132 5133 5134 5135 5136 5137 The Registry must provide an authorization mechanism based on the information model defined in [ebRIM]. In this version of the specification the authorization mechanism is based on a default Access Control Policy defined for a pre-defined set of roles for Registry users. Future versions of this specification will allow for custom Access Control Policies to be defined by the Submitting Organization. The authorization is applied based upon a specific set of privileges. A privilege is the ability to carry out a specific action such as invoking a method on the LifeCycleManager or QueryManager interface. 5138 12.7 Access Control 5139 5140 The Registry must create a default AccessControlPolicy object that grants default permissions to Registry users (as defined in Section 5.3) to access Registry Objects based upon their assigned Registry Client needs the public key of the Registration Authority to validate the Registry’s signature. Registry Client RC1 needs the public key of Registry Client RC2 to validate the content signed by RC1. [XMLDSIG] provides an optional ds:KeyInfo element that can be used to pass information to the recipient for retrieving the public key. This field together with the procedures outlined in this section is used to securely pass the public key to a recipient. If the KeyInfo field is present, it must contain a X509 Certificate as specified in [XMLDSIG]. Copyright © OASIS, 2002.

Role Permissions ContentOwner Access to all methods on Registry Objects that are owned by the actor who is assigned this role. RegistryAdministrator Access to all methods on all Registry Objects GuestReader Access to some read-only (getXXX) methods on some Registry Objects (read-only access to some content) as defined in the default access control policy.

The following list summarizes the default AccessControlPolicy: Only a Registered User can publish content. An unauthenticated Registry Client has access to all QueryManager methods operating on any Registry Objects as permitted for GuestReader role. The Registry must assign the default GuestReader role to such Registry Clients. Copyright © OASIS, 2002.

This enables a Submitting Organization to define Access Control Policies that are different from the default Access Control Policy. Such custom policies may allow other parties to perform privileged life cycle management operations on objects owned by the Submitting Organization. It may also restrict read-only access to other parties on sensitive objects owned by the Submitting Organization. A registry may allow a Submitting Organization to define custom Access Control Policies in an implementation specific manner. The SubmittingOrganization has access to all QueryManager or LifeCycleManager methods operating on Registry Objects submitted by the Submitting Organization. This version of the specification does not distinguish between Submitting Organization and Responsible Organization, and assumes that the Submitting Organization is also the Responsible Organization. The RegistryAdministrator and Registry Authority have access to all methods on all Registry Objects. At the time of content submission, the Registry must assign the default ContentOwner role to the registered User as authenticated by the credentials in the submission message.

The UML class diagram contains: 5222 C.2 UML Sequence Diagram 5223 5224 5225 5226 5227 5228 5229 5230 5231 5232 5233 5234 A UML sequence diagram is used to specify the business protocol representing the interactions between the UML interfaces for a Registry specific ebXML business process. A UML sequence diagram provides the necessary information to determine the sequencing of messages and request to response association as well as request to error response association. Each sequence diagram shows the sequence for a specific conversation protocol as method calls from the requestor to the responder. Method invocation may be synchronous or asynchronous based on the UML notation used on the arrowhead for the link. A half arrowhead represents asynchronous communication. A full arrowhead represents synchronous communication. Each method invocation may be followed by a response method invocation from the responder to the requestor to indicate the ResponseName for the previous Request. Possible error response is indicated by a conditional response method invocation from the responder to the requestor. See Figure 7 on page 35 for an example. 1. A collection of UML interfaces where each interface represents a Registry Service interface. 2. Tabular description of methods on each interface where each method represents an Action (as defined by [ebCPP]) within the Service Interface. 3. One or more parameters for each method. The type of each parameter represents the ebXML message type that is exchanged as part of the Action corresponding to the method. Multiple arguments imply multiple payload documents within the body of the corresponding ebXML message. Copyright © OASIS, 2002.

A <table reference> does not have the optional AS between <table name> and <correlation name>. 5250 5251 5252 7. Restricted use of sub-queries is allowed by the syntax as follows. The <in predicate> allows for the right hand side of the <in predicate> to be limited to a restricted <query specification> as defined above. 5253 5254 8. The SQL query syntax allows for the use of <sql invoked routines> invocation from [SQL/PSM] as the RHS of the <in predicate>. 5255 D.2 Non-Normative BNF for Query Syntax Grammar 5256 5257 5258 5259 5260 5261 5262 5263 5264 5265 5266 5267 5268 5269 5270 5271 5272 5273 5274 5275 5276 5277 5278 5279 5280 5281 5282 The following BNF exemplifies the grammar for the registry query syntax.

It is meant to be illustrative not prescriptive. Registries may choose to have different implementations as long as they support the default security roles and authorization rules described in this document. 5363 E.1 Security Concerns 5364 5365 5366 The security risks broadly stem from the following concerns. After a description of these concerns and potential solutions, we identify the concerns that we address in the current specification 5367 1. Is the content of the registry (data) trustworthy? 5368 5369 5370 5371 5372 a) How to make sure “what is in the registry” is “what is put there” by a submitting organization? This concern can be addressed by ensuring that the publisher is authenticated using digital signature (Source Integrity), message is not corrupted during transfer using digital signature (Data Integrity), and the data is not altered by unauthorized subjects based on access control policy (Authorization) 5373 5374 5375 5376 b) How to protect data while in transmission? Communication integrity has two ingredients – Data Integrity (addressed in 1a) and Data Confidentiality that can be addressed by encrypting the data in transmission. How to protect against a replay attack? 5377 5378 c) Is the content up to date? The versioning as well as any time stamp processing, when done securely will ensure the “latest content” is guaranteed to be the latest content. 5379 5380 d) How to ensure only bona fide responsible organizations add contents to registry? Ensuring Source Integrity (as in 1a). 5381 5382 e) How to ensure that bona fide publishers add contents to registry only at authorized locations? (System Integrity) 5383 5384 f) What if the publishers deny modifying certain content after-the-fact? To prevent this (Nonrepudiation) audit trails may be kept which contain signed message digests. 5385 g) What if the reader denies getting information from the registry? 5386 5387 2. How to provide selective access to registry content? The broad answer is, by using an access control policy – applies to (a), (b), and (c) directly. 5388 5389 a) How does a submitting organization restrict access to the content to only specific registry readers? 5390 5391 b) How can a submitting organization allow some “partners” (fellow publishers) to modify content? 5392 c) How to provide selective access to partners the registry usage data? 5393 5394 5395 d) How to prevent accidental access to data by unauthorized users? Especially with hw/sw failure of the registry security components? The solution to this problem is by having System Integrity. 5396 e) Data confidentiality of RegistryObject Copyright © OASIS, 2002. All Rights Reserved Page 155 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 5397 5398 5399 3. How do we make “who can see what” policy itself visible to limited parties, even excluding the administrator (self & confidential maintenance of access control policy). By making sure there is an access control policy for accessing the policies themselves. 5400 5401 5402 5403 5404 5405 5406 4. How to transfer credentials? The broad solution is to use credentials assertion (such as being worked on in Security Assertions Markup Language (SAML)). Currently, Registry does not support the notion of a session. Therefore, some of these concerns are not relevant to the current specification. a) How to transfer credentials (authorization/authentication) to federated registries? b) How do aggregators get credentials (authorization/authentication) transferred to them? c) How to store credentials through a session? 5407 E.2 Authentication 5408 1. As soon as a message is received, a principal object is created. 5409 5410 5411 2. If the message is signed, it is verified (including the validity of the certificate) and the DN of the certificate becomes the identity of the principal. Then the Registry is searched for the principal and if found, the roles and groups are filled in. 5412 5413 3. If the message is not signed, a principal is created with the role RegistryGuest. This step is suggested for symmetry and to decouple the rest of the processing. 5414 4. The message is then processed for the Action and the objects it will act on. 5415 E.3 Authorization 5416 5417 5418 5419 For every object, the access controller will iterate through all the AccessControlPolicy objects to verify that the requested method is permitted for the Principal. If any of the permission objects associated with the object, have a common role, identity, or group with the principal, then the action is permitted. 5420 E.4 Registry Bootstrap 5421 5422 5423 When a Registry is newly created, a default Principal object should be created with the identity of the Registry Administrator’s certificate DN with a role Registry Administrator. This way, any message signed by the Registry Administrator will get all the privileges. 5424 5425 5426 When a Registry is newly created, an instance of AccessControlPolicy is created as the default AccessControlPolicy. This includes the creation of the necessary Permission instances as well as the Privileges and Privilege attributes. 5427 E.5 Content Submission – Client Responsibility 5428 5429 The Registry client must sign the contents before submission – otherwise the content will be rejected. 5430 E.6 Content Submission – Registry Responsibility 5431 5432 1. As with any other request, the Registry Client will first be authenticated. In this case, the Principal object will get the DN from the certificate. Copyright © OASIS, 2002. All Rights Reserved Page 156 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 5433 2. As per the request in the message, the RegistryObject will be created. 5434 3. The RegistryObject is assigned the default AccessControlPolicy. 5435 5436 4. If the Registry Client is not previously registered, the registry may either reject the request or accept it and implicitly register the Registry Client. 5437 5438 E.7 Content Remove/Deprecate – Client Responsibility 5439 5440 The Registry client must sign the header before submission, for authentication purposes; otherwise, the request will be rejected 5441 E.8 Content Remove/Deprecate – Registry Responsibility 5442 5443 5444 1. As with any other request, the Registry Client will first be authenticated. In this case, the Principal object will get the DN from the certificate. As there will be a principal with this identity in the Registry, the Principal object will get all the roles from that object. 5445 5446 2. As per the request in the message (remove or deprecate), the appropriate method in the RegistryObject class will be accessed. 5447 5448 3. The access controller performs the authorization by iterating through the Permission objects associated with this object via the default AccessControlPolicy. 5449 5450 4. If authorization succeeds then the action will be permitted. Otherwise an error response is sent back with a suitable AuthorizationException error message. 5451 E.9 Using ds:KeyInfo Field 5452 Two typical usage scenarios for ds:KeyInfo are described below. 5453 Scenario 1 5454 1. Registry Client (RC) signs the payload and the SOAP envelope using its private key. 5455 2. The certificate of RC is passed to the Registry in KeyInfo field of the header signature. 5456 3. The certificate of RC is passed to the Registry in KeyInfo field of the payload signature. 5457 4. Registration Authority retrieves the certificate from the KeyInfo field in the header signature. 5458 5459 5. Registration Authority validates the header signature using the public key from the certificate. 5460 5461 5462 5463 6. Registration Authority validates the payload signature by repeating steps 4 and 5 using the certificate from the KeyInfo field of the payload signature. Note that this step is not an essential one if the onus of validation is that of the eventual user, another Registry Client, of the content. 5464 Scenario 2 5465 5466 1. RC1 signs the payload and SOAP envelope using its private key and publishes to the Registry. Copyright © OASIS, 2002. All Rights Reserved Page 157 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 5467 2. The certificate of RC1 is passed to the Registry in the KeyInfo field of the header signature. 5468 5469 5470 3. The certificate of RC1 is passed to the Registry in the KeyInfo field of the payload signature. This step is required in addition to step 2 because when RC2 retrieves content, it should see RC1’s signature with the payload. 5471 4. RC2 retrieves content from the Registry. 5472 5473 5. Registration Authority signs the SOAP envelope using its private key. Registration Authority sends RC1’s content and the RC1’s signature (signed by RC1). 5474 5475 5476 6. Registration Authority need not send its certificate in the KeyInfo field sinceRC2 is assumed to have obtained the Registration Authority’s certificate in an implementation-specific manner and installed it in its local key store. 5477 5478 7. RC2 obtains Registration Authority’s certificate out of its local key store and verifies the Registration Authority’s signature. 5479 5480 8. RC2 obtains RC1’s certificate from the KeyInfo field of the payload signature and validates the signature on the payload. Copyright © OASIS, 2002.

[RFC 2130]. Examples of CCS are ISO-10646, US-ASCII, ISO-8859-1, and so on. 5488 F.1.2 Character Encoding Scheme (CES): 5489 5490 CES is a mapping from a CCS (or several) to a set of octets. [RFC 2130]. Examples of CES are ISO-2022, UTF-8. 5491 F.1.3 Character Set (charset): 5492 5493 5494 5495 F.2 NLS And Request / Response Messages 5496 5497 5498 5499 5500 5501 5502 5503 5504 For the accurate processing of data in both registry client and registry services, it is essential to know which character set is used. Although the body part of the transaction may contain the charset in xml encoding declaration, registry client and registry services shall specify charset parameter in MIME header when they use text/xml. Because as defined in [RFC 3023], if a text/xml entity is received with the charset parameter omitted, MIME processors and XML processors MUST use the default charset value of "us-ascii". For example: 5505 5506 5507 Also, when an application/xml entity is used, the charset parameter is optional, and registry client and registry services must follow the requirements in Section 4.3.3 of [REC-XML] which directly address this contingency. 5508 If another Content-Type is used, then usage of charset must follow [RFC 3023]. 5509 F.3 NLS And Storing of RegistryObject 5510 This section provides NLS guidelines on how a registry should store RegistryObject instances. 5511 5512 5513 A single instance of a concrete sub-class of RegistryObject is capable of supporting multiple locales. Thus there is no language or character set associated with a specific RegistryObject instance. 5514 5515 A single instance of a concrete sub-class of RegistryObject supports multiple locales as follows. Each attribute of the RegistryObject that is I18N capable (e.g. name and description attributes in Native Language Support (NLS) charset is a set of rules for mapping from a sequence of octets to a sequence of characters.[RFC 2277],[RFC 2278]. Examples of character set are ISO-2022-JP, EUC-KR. A list of registered character sets can be found at [IANA]. Content-Type: text/xml; charset=ISO-2022-JP Copyright © OASIS, 2002. All Rights Reserved Page 159 of 167 OASIS/ebXML Registry Services Specification v2.0 March 2016 5516 5517 5518 5519 5520 RegistryObject class) as defined by [ebRIM], may have multiple locale specific values expressed as LocalizedString sub-elements within the XML element representing the I18N capable attribute. Each LocalizedString sub-element defines the value of the I18N capable attribute in a specific locale. Each LocalizedString element has a charset and lang attribute as well as a value attribute of type string. 5521 F.3.1 Character Set of LocalizedString 5522 5523 The character set used by a locale specific String (LocalizedString) is defined by the charset attribute. It is highly recommended to use UTF-8 or UTF-16 for maximum interoperability. 5524 F.3.2 Language Information of LocalizedString 5525 The language may be specified in xml:lang attribute (Section 2.12 [REC-XML]). 5526 F.4 NLS And Storing of Repository Items 5527 5528 5529 5530 This section provides NLS guidelines on how a registry should store repository items. While a single instance of an ExtrinsicObject is capable of supporting multiple locales, it is always associated with a single repository item. The repository item may be in a single locale or may be in multiple locales. This specification does not specify the repository item. 5531 F.4.1 Character Set of Repository Items 5532 5533 5534 5535 5536 5537 The MIME Content-Type mime header for the mime multipart containing the repository item MAY contain a charset attribute that specifies the character set used by the repository item. For example: 5538 5539 It is highly recommended to use UTF-16 or UTF-8 for maximum inter-operability. The charset of a repository item must be preserved as it is originally specified in the transaction. 5540 F.4.2 Language information of repository item 5541 5542 5543 The Content-language mime header for the mime bodypart containing the repository item may specify the language for a locale specific repository item. The value of the Content-language mime header property must conform to [RFC 1766]. 5544 5545 5546 5547 5548 This document currently specifies only the method of sending the information of character set and language, and how it is stored in a registry. However, the language information may be used as one of the query criteria, such as retrieving only DTD written in French. Furthermore, a language negotiation procedure, like registry client is asking a favorite language for messages from registry services, could be another functionality for the future revision of this document.
