 Overview of Design Management (DM)
 Defining a domain with DM
 The remaining challenges

 DM is a collaborative web-based tool that enables stakeholders to contribute to and influence the design of software and systems.
 DM embraces the Semantic Web principles: Linked Data, Open-world assumption
 DM is implemented as a set of web services on top of the Jazz platform
 DM capabilities are integrated in two products:
 Rational Software Architect Design Manager (beta available on Jazz.net)
 Rational Rhapsody Design Manager (beta available on Jazz.net)
3

 Domain definition
 Declaratively define a modeling domain along with a domain-specific tool for it.
 In-context collaboration
 Create, share and review models collaboratively using a web client with stakeholders.
 Change management for designs
 Store and manage model elements on a server directly (i.e., no need to map to files)
 Traceability and impact analysis
 Set up links between model elements, trace between them and analyze impact of change
 Reporting and document generation
 Use document/report templates to generate and share documents and reports
 Other: Validation, Transformation, Migration of models

 Overview of Design Management (DM)
 Defining a domain with DM
 The remaining challenges

 A domain is a definition of a domain-specific modeling language and its tooling
 Before Design Management
 A domain was defined as either a MOF (EMF) metamodel or a UML profile
 A model is serialized in XMI and queried using OCL/XPath
 Closed world assumption: hard to integrate domains or extend models
 Most domain-specific tooling was code driven
 With Design Management
 A domain is defined as a set of OWL ontologies
 A model is serialized in RDF and queries using SPARQL
 Open world assumption: easy to integrate domains and extend models
 Most domain-specific tooling is data driven
7

 DM Domain Toolkit allows for defining a domain declaratively:
 The abstract syntax is defined with a set of OWL ontologies (with DM extensions)
 The concrete graphical syntax is defined with a mapping to a graphics
 Various (diagram, tree or form based) editors can be defined in details
 Live and batch validation rules can be defined in several expression languages
 Future aspects: transformation, migration, inference…etc.
 Several domains are prepackaged:
 UML (ontology is imported from EMF)
 BPMN (ontology is imported from EMF)
 Topology
 Sketcher
 Rich Text

 DM provides a Core domain that consists of several ontologies including:
 XSD/RDF/RDFS/OWL (subset) for concept (class/property) modeling
 DM Core fills some gaps in concept modeling
 DM Editor/Explorer for defining content, layout and behavior of various kinds of editors
 DM File/Folder for defining domain-independent hierarchical organization of models
 DM Validation/Problem for defining validation rules using a number of languages
 DM Index/Query for controlling search/traceability related aspects on models
 DM Reporting/UI for controlling various UI and reporting aspects
13

 DM Core fills some gaps in concept modeling by special annotations
 Document boundaries: which concepts should be defined in separate documents?
 dmcore:DocumentClass (class)
 dmcore:canDefine (property of dmcore:DocumentClass)
 Deletion cascade: how to cascade deletion of a model element?
 dmcore:deleteCascade (property of owl:ObjectProperty)
 Detailed container modeling: what is the type of container members?
 dmcore:allMembersFrom (property of owl:Restriction)
 Initial values for properties: is there an initial value for a property?
 dmcore:hasInitialValue (property of owl:Restriction)
 Type compatibility: can two given types be used together on a model element?
 dmcore:compatibleWith (property of owl:Class)

 Overview of Design Management (DM)
 Defining a domain with DM
 The remaining challenges

 Scalable Inferencing
 We need some level of scalable inferencing support for OWL ontologies
 Validation based on semantics of OWL
 We need to validate models against their ontology definition (a use case for inference?)
 Scalable and extensible SPARQL Queries
 We need SPARQL queries to scale regardless of order of statements in query
 We need the ability to define a library of useful utility functions to be used in SPARQL
 Derived properties
 We need a strategy to derive values of some properties such that they can be queried
16

 Model to model mapping
 We need a way to declaratively define a mapping between two domains
 We need the mapping to define document
 Model Migration
 We need a way to automatically migrate models when domains change
 Model Refactoring
 We need a way to perform model refactoring (update)
17

 Diagram Definition
 We need to define a diagram interchange ontology
 We need a way to declare the graphical syntax of a diagram (rendering rules)
 Scalable diagram loading
 We need a way to load diagrams incrementally as they are browsed
 Diagram Auto layout
 We need a way to declare auto layout strategy for a diagram
 Mapping OWL to UML Notation
 We need to define a mapping of the UML notation to OWL
 Multi resource editing
 We need a way to declare which resources should be impacted by a high level gesture
18

 Domain Extensibility
 We need a strategy for automatically managing extensions across document boundaries
 Domain Subsetting
 We need a strategy for defining a subset of a domain that should be visible
