Express uml aka part 25 edition 2

EXPRESS/UML aka Part 25 Edition 2

Bath STEP July 2004


Agenda

Agenda

  • Update on EXPRESS/UML implementations

  • Discuss draft NWI for Part 25 Edition 2

  • Relationship of STEP and OMG MDA/UML

  • Plan next actions


Implementation

Implementation

  • IAI IFC team implementing

  • David Price implementing

    • Now enough coverage to publish ISO 15926-2 as UML on EXPRESS for Free (exff.org)

  • Used in OMG PLM Services Spec recently adopted

  • Others?


Nwi discussion starter 1

NWI Discussion Starter(1)

  • Part 25 E1 is one-way EXPRESS Edition 1 to UML 1.5

    • designed to support STEP implementation using UML-based software engineering tools

    • resulting UML is not tagged as being from EXPRESS

  • Proposing that Part 25 Edition 2 do the following

    • stay based on UML 1.5

    • extend the current mapping to cover EXPRESS Edition 2

    • add new capability to represent EXPRESS Edition 2 constructs annotated as EXPRESS

      • In OMG terms, this is a "UML Profile for EXPRESS".

    • extend use of Object Constraint Language where straightforward

      • Not expecting to include complete support for all of EXPRESS expressions


Nwi discussion starter 2

NWI Discussion Starter(2)

  • Part 25 Edition 2 scenarios

    • continue to support Edition 1 usage : STEP implementation using UML-based software engineering tools

    • support EXPRESS and UML constructs on the same UML diagram

    • enable the use of UML tools to create EXPRESS schemas in a manner similar to the way EXPRESS-G tools are used today

    • enable the use of UML in the specification of a complete software system that includes EXPRESS constructs and the use of EXPRESS in the context of the OMG Model Driven Architecture


Nwi discussion starter 3

NWI Discussion Starter(3)

  • Technical approach expectations

    • UML Stereotypes and Tagged Values, not extensions to UML itself, will be used to define this aspect of Part 25 Edition 2

  • UML 2 and MOF 2 are not yet finalized or commercially available in UML tools so, Part 25 Edition 2 is focused on UML 1.5.

  • Suggesting Part 25 Edition 3 will be required to address UML2 and MOF 2 in 2005


After change management review

After Change Management Review

  • Publication approach

    • Publish technically complete Edition 1 as-is today

    • Defer remaining editorial comments to Edition 2

    • Submit Edition 2 NWI ASAP

      • Publish working draft in September

      • Walkthough at Seattle in October

      • Submit for CD TS ballot December

      • Walkthrough in Lillehammer and discuss early ballot comments

      • Ballot resolution workshop April/May 2005

      • TS publication May/June 2005

    • Edition 3 work on UML 2 can begin informally in November/December once OMG Final Spec is available

    • NWI for Edition 3 as soon as major technical work on Edition 2 complete
