3 Introduction
382
3.1 Summary of Contents of Document
383
384
This document defines the interface to the ebXML Registry Services as well as interaction
protocols, message definitions and XML schema.
385
386
387
A separate document, ebXML Registry Information Model [ebRIM], provides information on
the types of metadata that are stored in the Registry as well as the relationships among the
various metadata classes.
388
3.2 General Conventions
389
The following conventions are used throughout this document:
390
391
UML diagrams are used as a way to concisely describe concepts. They are not intended to
convey any specific Implementation or methodology requirements.
392
393
394
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.
395
396
397
398
399
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].
400

4 Design Objectives
413
4.1 Goals
414
415
416
417
418
The goals of this version of the specification are to:
Communicate functionality of Registry services to software developers
Specify the interface for Registry clients and the Registry
Provide a basis for future support of more complete ebXML Registry requirements
Be compatible with other ebXML specifications
419
4.2 Caveats and Assumptions
420
421
422
This version of the Registry Services Specification is the second in a series of phased
deliverables. Later versions of the document will include additional capability as deemed
appropriate by the OASIS/ebXML Registry Technical Committee. It is assumed that:
423
424
425
426
427
428
429
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.

5 System Overview
431
5.1 What The ebXML Registry Does
432
433
434
435
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.
436
5.2 How The ebXML Registry Works
437
438
439
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.
440
441
442
443
444
445
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).
446
5.2.1 Schema Documents Are Submitted
447
448
449
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.
450
5.2.2 Business Process Documents Are Submitted
451
452
453
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.
454
5.2.3 Seller’s Collaboration Protocol Profile Is Submitted
455
456
457
458
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.
459
5.2.4 Buyer Discovers The Seller
460
461
462
463
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.
464
The buyer discovers the seller’s CPP and decides to engage in a partnership with the seller.

OASIS/ebXML Registry Services Specification v3.0
February 2016
465
5.2.5 CPA Is Established
466
467
468
469
470
471
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].
472
5.3 Registry Users
473
474
475
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.

6 ebXML Registry Architecture
511
512
513
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.
514
515

6.1 Registry Service Described
517
518
519
520
521
522
523
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.
524
525
526
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.

527
6.2 Abstract Registry Service
528
The architecture defines the ebXML Registry as an abstract registry service that is defined as:
529
1. A set of interfaces that must be supported by the registry.
530
2. The set of methods that must be supported by each interface.
531
3. The parameters and responses that must be supported by each method.
532
533
534
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.
535
536
537
The abstract registry service (Figure 3) shows how an abstract ebXML Registry must provide
two key functional interfaces called QueryManager1 (QM) and LifeCycleManager2
(LM).
538
539

(WSDL) syntax.
542
6.2.1 LifeCycleManager Interface
543
544
545
546
547
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].
548
Table 2: LifeCycle Manager Summary

549
6.2.2 QueryManager Interface
550
551
552
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.
553
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.
554
555
6.3 Concrete Registry Services
556
557
The architecture allows the abstract registry service to be mapped to one or more concrete
registry services defined as:

558
559
560
561
562
563
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
564
565
566
567
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.
568
569
570
Figure 4: A Concrete ebXML Registry Service
571
572
573
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).
574
575
576
577
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.

6.4 SOAP Binding
579
6.4.1 WSDL Terminology Primer
580
581
582
583
584
585
586
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.
587
588
589
590
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

591
ports, where each port simply adds address information such as a URL for each concrete port.

612
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.
613
The complete WSDL description for the SOAP binding can be obtained via a hyperlink in 0.

6.5 ebXML Message Service Binding
615
6.5.1 Service and Action Elements
616
617
618
619
620
621
622
623
624
625
626
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”).
627
628
629
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.
630
6.5.2 Synchronous and Asynchronous Responses
631
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>

633
634
635
636
637
638
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:

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

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
654
6.5.3 ebXML Registry Collaboration Profiles and Agreements
655
656
657
658
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.
659
660
661
662
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.
663
664
665
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.
666
6.6 REST Binding
667
668
669
670
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

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.
681
6.6.1 Standard URI Parameters

805
806
807
808
809
The REST interface supports the same mechanisms that are specified in chapter 12.
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.

814
815
816
817
818
819
820
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.

832
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.
833
834
835
836
837
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.

855
856
857
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.
858
6.7.2.1
859
860
861
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 171
OASIS/ebXML Registry Services Specification v3.0
February 2016
862
RegistryService may be accessed via a URL specified in the WSDL for the registry.
863
864
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.
865
866
867
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.
868

869
870
871
872
873
874
875
876
877
878
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.
879
6.7.2.3
880
881
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.
882
6.7.3 RegistryClient Interface
883
884
885
886
887
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.
888
The registry sends all asynchronous responses to operations via the onResponse method.

6.8 Interoperability Requirements
894
6.8.1 Client Interoperability
895
896
897
The architecture requires that any ebXML compliant registry client can access any ebXML
compliant registry service in an interoperable manner. An ebXML Registry must implement a
REST binding and either or both of the ebMS and SOAP/HTTP bindings.

903
904
905
906
907
This section describes the generic aspects that are common to all requests/responses
sent/received by registry clients/registry to the registry/registry clients.
Each registry 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.
908
6.9.1 RegistryRequestType

This section defines the Lifecycle Management service of the Registry. 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.
1018
1019
1020
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.
1021
7.1 Lifecycle of a RegistryObject
1022
1023
The main purpose of the LifeCycleManagement service is to manage the lifecycle of
RegistryObjects. Figure 10 shows the typical lifecycle of a RegistryObject.

7.2 RegistryObject Attributes
1027
1028
1029
1030
1031
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.

7.3 The Submit Objects Protocol
1033
1034
1035
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.
1036
1037

For details on the schema for the Business documents shown in this process refer to Appendix B.
1039
7.3.1 SubmitObjectsRequest
1040
1041
The SubmitObjectsRequest is used by a client to submit RegistryObjects and/or repository items
to the registry.

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:
1049
1050
NoIndexing: This specifies that the registry must not index any of the
objects submitted via this request.
1051
1052
IndexModificationNotAllowed: This specifies that the registry may index
any of the objects submitted via this request as long as the original objects

1053
are not modified by the indexing operations.
1054
1055
1056
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.
1057
1058
1059
1060
1061
1062
LeafRegistryObjectsList: This parameter specifies a collection of RegistryObject
instances that are being submitted to the registry. The RegistryObjects in the list
may be brand new objects being submitted to the registry or they may be current
objects already existing in the registry. In case of existing objects the registry
must treat them in the same manner as UpdateObjectsRequest and simply update
the existing objects.
1063
1064
7.3.1.3
1065
This request returns a RegistryResponse. See section 7.3.2 for details.
1066
7.3.1.4
1067
In addition to the exceptions common to all requests, the following exceptions may be returned:
Returns:
Exceptions:
1068
1069
AuthorizationException: Indicates that the requestor attempted to perform an
operation for which she was not authorized.
1070
1071
ObjectNotFoundException: Indicates that the requestor referenced an object
within the request that was not found.
1072
1073
ObjectExistsException: Indicates that the requestor tried to submit an object using
an id that matched the id of an existing object in the registry.
1074
1075
InvalidRequestException: Indicates that the requestor attempted to perform an
operation which was semantically invalid.
1076
1077
UnsupportedCapabilityException: Indicates that the requestor attempted to
submit some content that is not supported by the registry.
1078
1079
QuotaExceededException: Indicates that the requestor attempted to submit more
content than the quota allowed for them by the registry.
1080
1081
7.3.2 RegistryResponse
1082
1083
1084
1085
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. The details of RegistryResponse are decsribed by
the RegistryResponseType in 6.9.2.
1086
7.3.3 Universally Unique ID Generation
1087
1088
1089
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].
Copyright © OASIS, 2002. All Rights Reserved
Page 39 of 171
OASIS/ebXML Registry Services Specification v3.0
1090
February 2016
(e.g. urn:uuid:a2345678-1234-1234-123456789012)
1091
1092
1093
1094
1095
1096
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.
1097
1098
1099
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].
1100
7.3.4 ID Attribute And Object References
1101
1102
1103
1104
1105
1106
1107
1108
1109
1110
1111
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
registry generated UUID upon submission.
1112
1113
1114
1115
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.
1116
Replace ID/IDREF with string??
1117
7.3.5 Audit Trail
1118
1119
The RS must create AuditableEvent objects with eventType Created for each RegistryObject
created via a SubmitObjectsRequest.
1120
7.3.6 Sample SubmitObjectsRequest

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.

1369
This section describes the protocol of the Registry Service that allows a Registry Client to update
one or more existing RegistryObjects and/or repository items in the registry on behalf of a
Submitting Organization. It is expressed in UML notation as described in Appendix C.

February 2016
indexingOption: Change to catalog. This parameter specifies the submitter’s
preference governing the indexing of the objects submitted via this request. Valid
values are:
1383
1384
NoIndexing: This specifies that the registry must not index any of the
objects submitted via this request.
1385
1386
1387
IndexModificationNotAllowed: This specifies that the registry may index
any of the objects submitted via this request as long as the original objects
are not modified by the indexing operations.
1388
1389
1390
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.
1391
1392
1393
1394
1395
1396
1397
1398
LeafRegistryObjectsList: This parameter specifies a collection of RegistryObject
instances that are being submitted to the registry. An object in the list may be a
current RegistryObject already in the registry and has the same id, or it may be a
brand new object being submitted to the registry. A registry should treat new
objects the same as it does for a SubmitObjectRequest. RegistryObjects must
include all required attributes, even those the user does not intend to change. A
missing attribute is interpreted as a request to set that attribute to NULL or in case
it has a default value, the default value will be assumed.

8 Query Management Service
1598
1599
1600
1601
1602
1603
This section describes the capabilities of the Registry Service that allow a client
(QueryManagerClient) to search for or query different kinds of registry objects in the ebXML
Registry using the QueryManager interface of the Registry. The Registry supports the following
query capabilities:
Filter Query
SQL Query
1604
1605
1606
1607
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.
1608
1609
In a future version of this specification, the W3C XQuery syntax may be considered as another
query syntax.
1610
1611
The Registry will hold a self-describing capability profile that identifies all supported
AdhocQuery options. This profile is described in Appendix G.
1612
8.1 Ad Hoc Query Request/Response
1613
1614
1615
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.
1616
1617
1618
1619
1620
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.
1621
1622
Any errors in the query request messages are indicated in the corresponding
AdhocQueryResponse message.

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].

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.
1714
1715
1716
1717
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.

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.

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.

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.
1756
1757
1758
1759
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.
1760
1761
1762
1763
1764
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 29

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.
1773
1774
1775
1776
1777
1778
1779
1780
1781
1782
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.
1783
1784
1785
1786
1787
1788
1789
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.
1790
1791
1792
1793
1794
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.
1795
1796
1797
1798
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

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.
1802
1803
1804
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.

Semantic Rules
1849
1. The semantic rules for each FilterQuery alternative are specified in subsequent subsections.
1850
1851
1852
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.
1853
1854
1855
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].
1856
1857
1858
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.
1859
1860
5. If a Branch or Query element for a class has no sub-elements then every persistent instance
of that class satisfies the Branch or Query.
1861
1862
1863
1864
1865
6. 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”.
1866
1867
1868
1869
1870
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”.
1871
8.2.2 RegistryObjectQuery
1872
Purpose
1873
1874
To identify a set of registry object instances as the result of a query over selected registry
metadata.

follows:
If no AssociationFilter is specified within the SourceAssociationBranch, then let AF be

object of some element of AF. If ROT is empty, then remove x from RO. If RO is empty
then continue to the next numbered rule.
If an ExternalIdentifierFilter is specified within the SourceAssociationBranch, then let
ROT be the set of ExternalIdentifier instances that satisfy the ExternalIdentifierFilter and
are the target object of some element of AF. If ROT is empty, then remove x from RO. If
RO is empty then continue to the next numbered rule.

be the set of RegistryObject instances that satisfy the RegistryObjectQuery and are the
target object of some element of AF. If ROT is empty, then remove x from RO. If RO is
empty then continue to the next numbered rule.
If a RegistryEntryQuery is specified within the SourceAssociationBranch, then let ROT
be the set of RegistryEntry instances that satisfy the RegistryEntryQuery and are the
target object of some element of AF. If ROT is empty, then remove x from RO. If RO is
empty then continue to the next numbered rule.
If a ClassificationSchemeQuery is specified within the SourceAssociationBranch, then let
ROT be the set of ClassificationScheme instances that satisfy the

A client application wishes to identify all RegistryObject instances that are classified by some
internal classification scheme and have some given keyword as part of the description of one of
the classification nodes of that classification scheme. The following query identifies all such
RegistryObject instances. The query takes advantage of the knowledge that the classification
scheme is internal, and thus that all of its nodes are fully described as ClassificationNode
instances.

A client is using the United Nations Standard Product and Services Classification (UNSPSC)
scheme and wants to identify all companies that deal with products classified as "Integrated
circuit components", i.e. UNSPSC code "321118". The client knows that companies have
registered their Collaboration Protocol Profile (CPP) documents in the Registry, and that each
such profile has been classified by UNSPSC according to the products the company deals with.
However, the client does not know if the UNSPSC classification scheme is internal or external to
this registry. The following query returns a set of approved registry entry instances for CPP’s of
companies that deal with integrated circuit components.

paragraph with n=x.
Let n be a classification node instance. If n does not have a parent node (i.e. if n is a base
level node), then remove x from CN and go to the next step; otherwise, let p be the parent
node of n. If a ClassificationNodeFilter element is directly contained in the
ClassificationNodeParentBranch and if p does not satisfy the ClassificationNodeFilter,
then remove x from CN. If CN is empty then continue to the next numbered rule. If a
ClassificationSchemeQuery element is directly contained in the
ClassificationNodeParentBranch and if defining classification scheme of p does not
satisfy the ClassificationSchemeQuery, then remove x from CN. If CN is empty then

next numbered rule; otherwise, let c be any member of CNC. If a
ClassificationSchemeQuery element is directly contained in the
ClassificationNodeChildrenBranch and if the defining classification scheme of c does not
satisfy the ClassificationSchemeQuery then remove c from CNC. If CNC is empty then
remove x from CN. If CN is empty then continue to the next numbered rule; otherwise,
let y be an element of CNC and continue with the next paragraph.
If the ClassificationNodeChildrenBranch element is terminal, i.e. if it does not directly
contain another ClassificationNodeChildrenBranch element, then continue to the next
numbered rule; otherwise, repeat the previous paragraph with the new
ClassificationNodeChildrenBranch element and with n = y.
f) Let CN be the set of remaining ClassificationNode instances. Evaluate inherited
RegistryObjectQuery over CN as explained in Section 8.2.2.

Path Filter Expression usage in ClassificationNodeFilter
2966
2967
2968
The path filter expression is used to match classification nodes in ClassificationNodeFilter
elements involving the path attribute of the ClassificationNode class as defied by the getPath
method in [ebRIM].
2969
2970
The path filter expressions are based on a very small and proper sub-set of location path syntax
of XPath.
2971
2972
2973
2974
The path filter expression syntax includes support for matching multiple nodes by using wild
card syntax as follows:
Use of ‘*’ as a wildcard in place of any path element in the pathFilter
Use of ‘//’ syntax to denote any descendent of a node in the pathFilter
2975
2976
2977
2978
2979
2980
2981
2982
It is defined by the following BNF grammar:
2983
2984
2985
In the above grammer, schemeId is the id attribute of the ClassificationScheme instance. In the
above grammar nodeCode is defined by NCName production as defined by
http://www.w3.org/TR/REC-xml-names/#NT-NCName.
2986
2987
2988
The semantic rules for the ClassificationNodeFilter element allow the use of path attribute as a
filter that is based on the EQUAL clause. The pattern specified for matching the EQUAL clause
is a PATH Filter expression.
pathFilter ::= '/' schemeId nodePath
nodePath ::= slashes nodeCode
| slashes ‘*’
| slashes nodeCode ( nodePath )?
Slashes ::= ‘/’ | ‘//’

3221
3222
A client application wishes to identify all package instances in the Registry that are empty. 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.
3223
3224
3225
3226
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. However,
the equivalent RegistryEntryQuery is often more complicated to write.

8.2.14 XML Clause Constraint Representation
3667
Purpose
3668
3669
3670
The simple XML FilterQuery utilizes a formal XML structure based on Predicate Clauses.
Predicate Clauses are utilized to formally define the constraint mechanism, and are referred to
simply as Clauses in this specification.

Semantic Rules
3677
3678
3679
Predicates and Arguments are combined into a "LeftArgument - Predicate - RightArgument"
format to form a Clause. There are two types of Clauses: SimpleClauses and CompoundClauses.
3680
3681
3682
3683
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).
3684
3685
3686
3687
3688
3689
3690
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.
3691
3692
A CompoundClause contains two or more Clauses (Simple or Compound) and a connective
predicate. This provides for arbitrarily complex Clauses to be formed.

8.3 SQL Query Support
3872
Need to update storedProcedures.sql, database.sql??
3873
3874
3875
3876
The Registry may optionally support an SQL based query capability that is designed for Registry
clients that demand more advanced query capability. The optional SQLQuery element in the
AdhocQueryRequest allows a client to submit complex SQL queries using a declarative query
language.
3877
3878
3879
3880
3881
3882
The syntax for the SQLQuery of the Registry is defined by a stylized use of a proper subset of
the “SELECT” statement of Entry level SQL defined by ISO/IEC 9075:1992, Database
Language SQL [SQL], extended to include <sql invoked routines> (also known as
stored procedures) as specified in ISO/IEC 9075-4 [SQL-PSM] and pre-defined routines defined
in template form in Appendix D.3. The syntax of the Registry query language is defined by the
BNF grammar in D.1.
3883
3884
Note that the use of a subset of SQL syntax for SQLQuery does not imply a requirement to use
relational databases in a Registry implementation.

8.3.1 SQL Query Syntax Binding To [ebRIM]
3886
3887
3888
SQL Queries are defined based upon the query syntax in in Appendix D.1 and a fixed relational
schema defined in Appendix D.3. The relational schema is an algorithmic binding to [ebRIM] as
described in the following sections.
3889
8.3.1.1
3890
3891
3892
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.
3893
3894
3895
3896
3897
3898
3899
3900
3901
3902
3903
3904
3905
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.
3906
3907
An SQLQuery against a table not defined in Appendix D.3 may raise an error condition:
InvalidQueryException.
3908
3909
The following sections describe the algorithm for mapping attributes of [ebRIM] to SQLcolumn
definitions.
3910
8.3.1.2
3911
3912
3913
3914
3915
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].
3916
8.3.1.3
3917
3918
3919
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.
3920
3921
3922
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.
3923
3924
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

by [SQL].
3926
Reference attribute binding is a special case of a primitive attribute mapping.
3927
8.3.1.4
3928
3929
3930
3931
3932
3933
3934
3935
3936
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.
3937
3938
3939
3940
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.
3941
8.3.1.5
3942
3943
3944
3945
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.
3946
3947
3948
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.
3949
3950
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.
3951
8.3.2 Semantic Constraints On Query Syntax
3952
3953
3954
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.
3955
1. Class names and attribute names must be processed in a case insensitive manner.
3956
3957
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].
3958
3959
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.
3960
8.3.3 SQL Query Results
3961
3962
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

3964
3965
3966
ObjectRef, RegistryObject, RegistryEntry or leaf ebRIM class depending upon the returnType
attribute of the responseOption parameter specified by the client on the AdHocQueryRequest.
The entire result set is returned as a SQLQueryResult as defined by the AdHocQueryResponse in
Section 8.1.
3967
8.3.4 Simple Metadata Based Queries
3968
3969
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.
3970
3971
3972
3973
3974
3975
3976
3977
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:
3978
3979
Note that the query syntax allows for conjugation of simpler predicates into more complex
queries as shown in the simple example above.
3980
8.3.5 RegistryObject Queries
3981
3982
3983
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.
3984
3985
3986
3987
3988
3989
3990
3991
3992
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”.
3993
8.3.6 RegistryEntry Queries
3994
3995
3996
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.
3997
3998
3999
4000
4001
4002
4003
4004
4005
4006
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);

8.3.7 Classification Queries
4008
This section describes various classification related queries.
4009
8.3.7.1
4010
4011
4012
4013
ClassificationNodes are identified by their ID, as are all objects in [ebRIM]. 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.
4014
8.3.7.2
4015
4016
4017
4018
The following query retrieves the collection of ClassificationSchemes :
4019
4020
The above query returns all ClassificationSchemes. Note that the above query may also specify
additional predicates (e.g. name, description etc.) if desired.
4021
8.3.7.3
4022
4023
4024
4025
The following query retrieves the children of a ClassificationNode given the ID of that node:
4026
4027
The above query returns all ClassificationNodes that have the node specified by <id> as their
parent attribute.

The following query retrieves the collection of ExtrinsicObjects classified by specified
ClassificationNodes:
4044
4045
4046
4047
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.
4048
8.3.7.5
4049
4050
4051
4052
4053
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

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:
Use the ID of the ExtrinsicObject instance as the value of the Content-ID header parameter
for the mime multipart that contains the corresponding repository item for the
ExtrinsicObject.
In case of [ebMS] transport, use the ID of the ExtrinsicObject instance in the Reference
element for that object in the Manifest element of the ebXMLHeader.

9 Content Management Services
4270
Fix pictures, schema for index to catalog name change??
4271
4272
4273
4274
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.
4275
4276
4277
4278
4279
4280
4281
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.
4282
9.1 Content Cataloging: Use Cases
4283
There are many scenarios where content-based discovery is necessary.
4284
9.1.1 Find All CPPs Where Role is “Buyer”
4285
4286
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”.
4287
9.1.2 Find All XML Schema’s That Use Specified Namespace
4288
4289
A client may wish to discover all XML Schema documents in the registry that use an XML
namespace containing the word “oasis”.
4290
9.1.3 Find All WSDL Descriptions with a SOAP Binding
4291
4292
4293
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.
4294
9.2 Content Cataloguing Service
4295
4296
4297
4298
4299
4300
Figure 45 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.

Figure 46 shows a UML instance diagram to illustrate how a Content Cataloguing Service is
used. 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.

9.3 Catalog Definition File
4319
4320

4323
4324
The Catalog Definition File describes the information that the Cataloging Service must extract
from the repository item and subsequently map it to the generated RegistryObject Metadata. 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.

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.

A content cataloguing service catalogs a repository item by processing it and extracting specific
information content as specified by the Catalog Definition File. 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.

4351
4352
4353
4354
4355
4356
4357
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.
4358
4359

9.6.1 CatalogContentRequest

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.

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 50 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 50 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.

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.

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.

4484
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.
4485
9.8.1 Referential Integrity and Dynamic Content Cataloguing
4486
4487
A registry must maintain referential integrity between the RegistryObjects and repository items
in the submission and the generated RegistryObjects in the catalogued metadata.
4488
9.8.2 Error Handling Model for Dynamic Content Cataloguing
4489
4490
4491
4492
4493
4494
4495
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.

9.8.3 Updates and Dynamic Content Cataloguing
4497
4498
When an ExtrinsicObject and its repository item are updated within a registry, the registry must
append any new catalog metadata to any previously created catalog metadata.
4499
9.8.4 Resolution Algorithm For Cataloging Service and Catalog Definition File
4500
4501
4502
When a registry receives a submission of an ExtrinsicObject EO1 and repository item pair, it
must use the following algorithm to determine or resolve the content cataloguing service and
Catalog Definition File to be used to catalog that content:
4503
4504
4505
4506
4507
1. 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??
4508
4509
4510
4511
4512
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.
4513
4514
4515
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.
4516
4517
4518
4519
4520
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.
4521
4522
4523
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.
4524
4525
4526
4527
4528
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.
4529
9.9 Dynamic Content-based Discovery
4530
4531
4532
4533
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.

4548
An ebXML Registry must provide the XML Content Cataloguing Service natively as a built-in
service. 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:
4549
9.10.1 Publishing of Default XML Content Cataloging Service
4550
4551
4552
4553
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.
4554
9.11 Canonical Catalog Definition Files
4555
4556
4557
4558
4559
4560
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.

10 Event Notification Service
4562
4563
4564
4565
4566
4567
4568
4569
4570
4571
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.
4572
10.1 Use Cases
4573
4574
The following use cases illustrate different ways in which ebXML registries notify users or other
registries.
4575
10.1.1 New Service is Offered
4576
4577
4578
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.
4579
10.1.2 Monitor Download of Content
4580
4581
4582
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.
4583
10.1.3 Monitor Price Changes
4584
4585
4586
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.
4587
10.1.4 Keep Replicas Consistent With Source Object
4588
4589
4590
4591
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.
4592
10.2 Registry Events
4593
4594
4595
4596
4597
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.

4598
10.3 Subscribing to Events
4599
4600
4601
4602
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.
4603
10.3.1 Event Selection
4604
4605
4606
4607
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??
4608
10.3.2 Notification Action
4609
4610
4611
4612
4613
4614
4615
4616
4617
4618
4619
4620
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.
4621
10.3.3 Subscription Authorization
4622
4623
4624
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.
4625
10.3.4 Subscription Quotas
4626
4627
4628
4629
4630
4631
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.

10.3.5 Subscription Expiration
4633
4634
4635
4636
4637
4638
4639
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.
4640
10.4 Unsubscribing from Events
4641
4642
4643
4644
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.
4645
10.5 Notification of Events
4646
4647
4648
4649
4650
4651
4652
4653
4654
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.
4655
10.6 Retrieval of Events
4656
4657
4658
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.
4659
10.6.1 GetNotificationsRequest
4660
4661
The GetNotificationsRequest is used by a client to retrieve any pending events for their
Subscriptions.

4671
10.6.1.4 Exceptions:
4672
In addition to the exceptions common to all requests, the following exceptions may be returned:
4673
4674
ObjectNotFoundException: signifies that a specified Subscription was not found
in the registry.
4675
10.6.2 GetNotificationsResponse
4676
4677
The GetNotificationsResponse is sent by the registry as a response to GetNotificationsRequest. It
contains the Notifications for the Subscription specified in the GetNotificationsRequest.

GetNotificationsResponse. The notification is actually delivered as a more
specialized sub-type (e.g. EventRefsNotification) as defined by [ebRIM].
4687
10.7 Purging of Events
4688
4689
4690
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.

11 Cooperating Registries Support
4692
4693
This chapter describes the capabilities and protocols that enable multiple ebXML registries to
cooperate with each other to meet advanced use cases.
4694
11.1 Cooperating Registries Use Cases
4695
4696
The following is a list of use cases that illustrate different ways that ebXML registries cooperate
with each other.
4697
11.1.1 Inter-registry Object References
4698
4699
4700
4701
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.
4702
4703
Figure 53: Inter-registry Object References
4704
4705
11.1.2 Federated Queries
4706
4707
4708
4709
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.
4710
11.1.3 Local Caching of Data from Another Registry
4711
4712
4713
4714
4715
4716
4717
4718
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.

11.1.4 Object Relocation
4720
4721
A Submitting Organization wishes to relocate its RegistryObjects and/or repository items from
the registry where it was submitted to another registry.
4722
11.2 Registry Federations
4723
4724
4725
4726
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.
4727
4728

4729
4730
4731
4732
4733
4734
4735
4736
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.
4737
11.2.1 Federation Metadata
4738
4739
4740
4741
4742
4743
4744
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.

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.

4751
11.2.2 Local Vs. Federated Queries
4752
4753
4754
4755
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.
4756
11.2.2.1 Local Queries
4757
4758
4759
4760
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.
4761
11.2.2.2 Federated Queries
4762
4763
4764
4765
4766
4767
4768
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.

11.2.2.3 Membership in Multiple Federations
4770
4771
4772
4773
4774
4775
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.
4776
11.2.3 Federated Lifecycle Management Operations
4777
4778
4779
4780
4781
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.
4782
11.2.4 Federations and Local Caching of Remote Data
4783
4784
4785
4786
4787
4788
4789
4790
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.
4791

4798
4799
4800
4801
4802
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.

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.

11.2.7 Federations and Security
4809
4810
Federation lifecycle management operations abide by the same security rules as standard
lifecycle management.
4811
11.2.8 Federation Lifecycle Management Protocols
4812
4813
4814
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.
4815
11.2.8.1 Joining a Federation

4818
4819
4820
4821
4822
4823
4824
4825
4826
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.
4827
11.2.8.2 Creating a Federation
4828
4829
4830
4831
4832
4833
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.
4834
11.2.8.3 Leaving a Federation
4835
4836
4837
4838
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.
4839
11.2.8.4 Dissolving a Federation
4840
4841
4842
4843
4844
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.

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.

11.3 Object Replication
4851
4852
4853
4854
4855
4856
4857
4858
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.
4859
4860

4861
4862
11.3.1 Use Cases for Object Replication
4863
4864
A registry may create a local replica of a remote object for a variety of reasons. A few sample
use cases follow:
4865
4866
4867
4868
4869
4870
4871
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.

11.3.2 Queries And Replicas
4873
4874
4875
4876
4877
4878
A registry must support client queries to consider a local replica of remote object as if it were a
local object. 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.
4879
11.3.3 Lifecycle Operations And Replicas
4880
4881
4882
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.
4883
11.3.4 Object Replication and Federated Registries
4884
4885
4886
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.
4887
11.3.5 Creating a Local Replica

4900
4901
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.
4902
4903
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.
4904
11.3.6 Transactional Replication
4905
4906
4907
4908
4909
4910
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

4911
4912
4913
4914
4915
4916
4917
Registry implementations are not required to implement transactional replication.
4918
11.3.7 Keeping Replicas Current
4919
4920
4921
4922
4923
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.
4924
11.3.8 Write Operations on Local Replica
4925
4926
4927
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.
4928
11.3.9 Tracking Location of a Replica
4929
4930
4931
4932
4933
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.
4934
11.3.10
4935
4936
4937
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.
4938
11.3.11
4939
4940
4941
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.
4942
11.4 Object Relocation Protocol
4943
4944
4945
4946
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

4950
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.

Figure 57: 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:
4962
4963
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.
4964
4965
4966
4967
4968
4969
4970
4971
4972
4973
4974
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.

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 58: Relocate Objects Protocol
Figure 47 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:
4985
4986
4987
4988
4989
4990
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.
4991
4992
4993
4994
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.
4995
4996
4997
4998
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.

5001
5002
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.
5003
5004
5. The destinationRegistry relays the AcceptObjectsRequest message to the sourceRegistry.
The source registry returns the objects being relocated as an AdhocQueryResponse.
5005
5006
5007
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.
5008
5009
7. The destinationRegistry notifies the sourceRegistry that the relocated objects have been
safely committed. Need to decide on the signal message name here??
5010
5011
8. The sourceRegistry removes the relocated objects using any registry specific means or a
RemoveObjectsRequest. This concludes the Object Relocation transaction.

5018
5019
5020
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.
5021
11.4.1.3 Element sourceRegistry
5022
5023
5024
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.

11.4.3 Object Relocation and Remote ObjectRefs
5037
The following scenario describes what typically happens when a person moves:
5038
5039

5041
5042
5043
5044
5045
5046
5047
5048
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.

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.

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.
5066
11.4.4 Notification of Object Relocation
5067
5068
5069

registry to notify the ownerAtDestination of a Relocated event.

5070
11.4.5 Object Relocation and Timeouts
5071
5072
5073
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.

12 Registry Security
5075
5076
5077
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.
5078
12.1 Security Concerns
5079
5080
5081
5082
5083
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.
5084
12.2 Integrity of Registry Content
5085
5086
5087
5088
5089
5090
5091
5092
5093
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.
5094
12.2.1 Message Payload Signature
5095
5096
5097
5098
5099
5100
5101
5102
5103
5104
5105
5106
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.
5107
Use Case
5108
5109
5110
5111
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.

A payload signature is represented by a ds:Signature element. 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.
5133
5134
The packaging of the payload signature with two payloads is as shown in the example in Section
8.4.4.

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:

o Must contain a <ds:DigestValue> which is computed as specified in [XMLDSIG].
5155
The ds:SignatureValue must be generated as specified in [XMLDSIG].
5156
5157
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”.
5158
12.2.2.3 Message Payload Signature Validation
5159
The ds:Signature element must be validated by the Registry as specified in the [XMLDSIG].

The following example shows the format of the payload signature:
5177
12.3 Authentication
5178
5179
The Registry must be able to authenticate the identity of the Principal associated with client
requests and also the owner of each repository item.
5180
5181
5182
5183
5184
5185
5186
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.
5187
5188
5189
5190
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.
5191
5192
5193
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.

12.3.1 Message Header Signature
5195
5196
Message headers are signed to provide data integrity while the message is in transit. Note that the
signature within the message header also signs the digests of the payloads.
5197
Header Signature Requirements
5198
5199
5200
5201
5202
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.
5203
5204
5205
5206
5207
5208
5209
5210
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.
5211
12.3.1.1 Packaging Requirements
5212
5213
5214
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 8.4.4.
5215
12.3.1.2 Header Signature Generation Requirements
5216
5217
5218
5219
5220
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
5221
The ds:SignedInfo element must be generated as follows:
5222
5223
5224
5225
5226
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.
5227
5228
5229
2. The ds:SignedInfo element must contain a ds:CanonicalizationMethod element. The
following Canonicalization algorithm (specified in [XMLDSIG]) must be supported:
5230
5231
5232
5233
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

This ensures that the signature (which is embedded in the <SOAP-ENV:Header>
element) is not included in the signature calculation.
o Must identify the <SOAP-ENV:Envelope> element using the URI attribute of the
ds:Reference element. 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].
5242
The ds:SignatureValue must be generated as specified in [XMLDSIG].
5243
5244
The ds:KeyInfo element may be present. When present, it is subject to the requirements stated in
Section 12.4, “KeyDistrbution and KeyInfo element”.
5245
12.3.1.3 Header Signature Validation Requirements
5246
5247
The ds:Signature element for the ebXML message header must be validated by the recipient as
specified by [XMLDSIG].

12.4 Key Distribution and KeyInfo Element
5269
5270
5271
5272
5273
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

5280
5281
5282
The following assumptions are also made:
5283
1. A Certificate is associated both with the Registration Authority and a Registry Client.
5284
5285
2. A Registry Client registers its certificate with the Registration Authority. The mechanism
used for this is not specified here.
5286
5287
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.
5288
Appendix F.8 contains a few scenarios on the use of KeyInfo field.
5289
12.5 Confidentiality
5290
12.5.1 On-the-wire Message Confidentiality
5291
5292
5293
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.
5294
12.5.2 Confidentiality of Registry Content
5295
5296
5297
5298
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.
5299
12.6 Authorization
5300
5301
5302
5303
5304
5305
5306
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.
5307
12.7 Access Control
5308
5309
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].

The Registry must implement the default AccessControlPolicy and associate it with all Objects
in the Registry. 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.

[ebRIM] allows for custom Access Control Policy objects to be defined on a per RegistryObject
basis. 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.

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 11 on page 38 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.

SQL Query
5406
D.1 SQL Query Syntax Specification
5407
5408
5409
This section specifies the rules that define the SQL Query syntax as a subset of SQL-92. The
terms enclosed in angle brackets are defined in [SQL] or in [SQL/PSM]. The SQL query syntax
conforms to the <query specification> as well as the additional restrictions identified below:
5410
Double check these restrictions with SQL spec??
5411
1. A <select list> may contain at most one <select sublist>.
5412
5413
2. The <select list> must be is a single column whose data type is UUID, from the table in the
<from clause>.
5414
3. A <derived column> may not have an <as clause>.
5415
5416
4. A <table expression> does not contain the optional <group by clause> and <having
clause> clauses.
5417
5. A <table reference> can only consist of <table name> and <correlation name>.
5418
5419
6. A <table reference> does not have the optional AS between <table name> and
<correlation name>.
5420
5421
5422
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.
5423
5424
8. The SQL query syntax allows for the use of <sql invoked routines> invocation from
[SQL/PSM] as the RHS of the <in predicate>.

Appendix E
Security Implementation Guideline
5529
5530
5531
5532
This section provides a suggested blueprint for how security processing may be implemented in
the Registry. 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.
5533
E.1 Security Concerns
5534
5535
5536
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
5537
1. Is the content of the registry (data) trustworthy?
5538
5539
5540
5541
5542
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)
5543
5544
5545
5546
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?
5547
5548
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.
5549
5550
d) How to ensure only bona fide responsible organizations add contents to registry?
Ensuring Source Integrity (as in 1a).
5551
5552
e) How to ensure that bona fide publishers add contents to registry only at authorized
locations? (System Integrity)
5553
5554
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.
5555
g) What if the reader denies getting information from the registry?
5556
5557
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.
5558
5559
a) How does a submitting organization restrict access to the content to only specific registry
readers?
5560
5561
b) How can a submitting organization allow some “partners” (fellow publishers) to modify
content?
5562
c) How to provide selective access to partners the registry usage data?
5563
5564
5565
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.
5566
e) Data confidentiality of RegistryObject
Copyright © OASIS, 2002. All Rights Reserved
Page 159 of 171
OASIS/ebXML Registry Services Specification v3.0
February 2016
5567
5568
5569
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.
5570
5571
5572
5573
5574
5575
5576
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?
5577
E.2 Authentication
5578
1. As soon as a message is received, a principal object is created.
5579
5580
5581
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.
5582
5583
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.
5584
4. The message is then processed for the Action and the objects it will act on.
5585
E.3 Authorization
5586
5587
5588
5589
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.
5590
E.4 Registry Bootstrap
5591
5592
5593
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.
5594
5595
5596
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.
5597
E.5 Content Submission – Client Responsibility
5598
5599
The Registry client must sign the contents before submission – otherwise the content will be
rejected.
5600
E.6 Content Submission – Registry Responsibility
5601
5602
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 160 of 171
OASIS/ebXML Registry Services Specification v3.0
February 2016
5603
2. As per the request in the message, the RegistryObject will be created.
5604
3. The RegistryObject is assigned the default AccessControlPolicy.
5605
5606
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.
5607
5608
E.7 Content Remove/Deprecate – Client Responsibility
5609
5610
The Registry client must sign the header before submission, for authentication purposes;
otherwise, the request will be rejected
5611
E.8 Content Remove/Deprecate – Registry Responsibility
5612
5613
5614
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.
5615
5616
2. As per the request in the message (remove or deprecate), the appropriate method in the
RegistryObject class will be accessed.
5617
5618
3. The access controller performs the authorization by iterating through the Permission objects
associated with this object via the default AccessControlPolicy.
5619
5620
4. If authorization succeeds then the action will be permitted. Otherwise an error response is
sent back with a suitable AuthorizationException error message.
5621
E.9 Using ds:KeyInfo Field
5622
Two typical usage scenarios for ds:KeyInfo are described below.
5623
Scenario 1
5624
1. Registry Client (RC) signs the payload and the SOAP envelope using its private key.
5625
2. The certificate of RC is passed to the Registry in KeyInfo field of the header signature.
5626
3. The certificate of RC is passed to the Registry in KeyInfo field of the payload signature.
5627
4. Registration Authority retrieves the certificate from the KeyInfo field in the header signature.
5628
5629
5. Registration Authority validates the header signature using the public key from the
certificate.
5630
5631
5632
5633
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.
5634
Scenario 2
5635
5636
1. RC1 signs the payload and SOAP envelope using its private key and publishes to the
Registry.
Copyright © OASIS, 2002. All Rights Reserved
Page 161 of 171
OASIS/ebXML Registry Services Specification v3.0
February 2016
5637
2. The certificate of RC1 is passed to the Registry in the KeyInfo field of the header signature.
5638
5639
5640
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.
5641
4. RC2 retrieves content from the Registry.
5642
5643
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).
5644
5645
5646
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.
5647
5648
7. RC2 obtains Registration Authority’s certificate out of its local key store and verifies the
Registration Authority’s signature.
5649
5650
8. RC2 obtains RC1’s certificate from the KeyInfo field of the payload signature and validates
the signature on the payload.

Appendix F
5652
F.1 Definitions
5653
5654
Although this section discusses only character set and language, the following terms have to be
defined clearly.
5655
F.1.1 Coded Character Set (CCS):
5656
5657
CCS is a mapping from a set of abstract characters to a set of integers. [RFC 2130]. Examples of
CCS are ISO-10646, US-ASCII, ISO-8859-1, and so on.
5658
F.1.2 Character Encoding Scheme (CES):
5659
5660
CES is a mapping from a CCS (or several) to a set of octets. [RFC 2130]. Examples of CES are
ISO-2022, UTF-8.
5661
F.1.3 Character Set (charset):
5662
5663
5664
5665
F.2 NLS And Request / Response Messages
5666
5667
5668
5669
5670
5671
5672
5673
5674
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:
5675
5676
5677
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.
5678
If another Content-Type is used, then usage of charset must follow [RFC 3023].
5679
F.3 NLS And Storing of RegistryObject
5680
This section provides NLS guidelines on how a registry should store RegistryObject instances.
5681
5682
5683
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.
5684
5685
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

OASIS/ebXML Registry Services Specification v3.0

5686
5687
5688
5689
5690
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.
5691
F.3.1 Character Set of LocalizedString
5692
5693
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.
5694
F.3.2 Language Information of LocalizedString
5695
The language may be specified in xml:lang attribute (Section 2.12 [REC-XML]).
5696
F.4 NLS And Storing of Repository Items
5697
5698
5699
5700
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.
5701
F.4.1 Character Set of Repository Items
5702
5703
5704
5705
5706
5707
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:
5708
5709
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.
5710
F.4.2 Language information of repository item
5711
5712
5713
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].
5714
5715
5716
5717
5718
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.
Content-Type: text/xml; charset="UTF-8"

Registry Profile
5720
Need to review relationship between profile and Registry class. How does this relate to REST??
5721
5722
5723
5724
5725
5726
Every registry must support exactly one Registry Profile. The Registry Profile is an XML
document that describes the capabilities of the registry. The profile document must conform to
the Registry Profile element as described in the Registry Services Interface schema defined in
Appendix B. The registry must make the Registry Profile accessible over HTTP protocol via a
URL. The URL must conform to the pattern:
http://<base url>/registryProfile
