IBM Software Group | Rational software 2 Agenda  DD Status  DI Metamodel  Example for UML  DI Refinements  DI more abstractions  DI concrete classes  DI extensibility  DI interchange format  DI common properties  DI style sheets  DG Discussions

IBM Software Group | Rational software 3 Problem Statement 1.Diagram Interchange  How diagrams should be represented and persisted (diagram syntax)  Changes  Connectors association is from View to Connector  Connectors are owned by lowest common parent of the source and target (constraint)  Waypoints are ordered and non unique  Master style sheet (ordered)  Change StyleRule.context to something different from View.context  Incorporate application style sheets 2.Diagram Graphics  How diagrams should be rendered to graphics (concrete syntax)

IBM Software Group | Rational software 4 Proposed Diagram Interchange (DI) MOF DI DSL M3 M2 M1 DSL DI user ModelDiagram Abstract Syntax Diagram Syntax spec  Diagram Interchange (DI) (replaces current DI)  Provides an abstract metamodel that defines diagram interchange syntax  Domains extend DI using inheritance to define domain specific DI  Diagrams are interchanged as instances of the domain-specific DI Is Instance of Inherits References

IBM Software Group | Rational software 8 UML Class Connectors

IBM Software Group | Rational software 9 DI More Abstractions  Try to have a crack at it but it is not critical (not show stopper)  Could define them as concrete to allow creating adhoc diagrams  Define common properties as mixin types in separate DI packages

IBM Software Group | Rational software 10 DI Extensibility  Profiles  Allow subsetting, redefinition of base properties in stereotypes  Clarify what types other than stereotypes are allowed in profiles and what it means  What DD needs to do to get access to profiles (package merge?)

IBM Software Group | Rational software 11 DI Interchange Format  XMI problems  XMI to XSD mapping is subject to options that individual specs did not agree to set  XMI to XSD mapping is not likeable and creates problems in XSD tools/communitiies  Propagate these requirements to XMI RTF  BPMN2 should address this problem on their own for now

IBM Software Group | Rational software 12 DI Style Sheets

IBM Software Group | Rational software 13 Proposed Diagram Graphics  Diagram Graphics (DG)  Provides an abstract metamodel that defines diagram graphics syntax  Provides a way to map the abstract syntax (DSL+DI) to the graphical syntax (DG)  Domains extend DG to create domain specific DG and its mapping from their DSL+DI DI DG Graphics DSL DG Mapping Model (abstract syntax) Controller (mapping) View (concrete syntax)
