Minutes
- Extension mechanism of BPMN lacks government, no context driver
- Alternatives should be positioned against the 4 pillars
- Controlled vocabulary (grammar)
- Context driver principle
- Tooling
- Processes
- Hard to find related work
- Implications & requirements
- Last slide in presentation
- Have to use CCTS grammar
- Transform from ecore to CCTS
- CCTS is geared at messages and business document, not services
- No modularization in CCTS
- Almost no tooling
- Tools from SAP != problem for users of USDL ==> global schema repository will need to be set up, run at W3C (?), no fees for users
- Disruption in modeling techniques
- Implication for folks in the XG
- No more ecore, modelling more complex
- Opinions
- + Dieter: fine
- o Max: no meaning
- (+) Carlos: yes, but encourages abstraction (vendor independence)
- o Bryan: would like middle way, annotate ecore, semi-governed
- o Massimo: not clear about the solution
- o Martin: supports Bryan, tool driven discussion
- o Roland:
- Test cases
- Call planned for next week
- Two test cases from Siemens planned (supporting services for Energy, health care)
- Test marketplace
- Ideas wanted
- Interested: Kay Kadner, Roland Hedberg, Maximilien Kintz
