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

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)

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

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


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?)


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

DI Style Sheets


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
