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
