[ebBP] 10/26/2004: ebBP-BPMN Collaboration

["Monica J. Martin" <Monica.Martin@Sun.COM>]

Updated BPMN diagram from JJ Dubray as of 21 October 2004 (attached).

BPMN - ebBP collaboration 21 Oct 2004
Summary:

    * The dual messages that connect to the BTA are important to
      represent the shared collaboration. Need to retain the BT (BTA
      with role) in BPMN to show the business messages, signals and
      exceptions. There are semantics associated with these patterns and
      activities in ebBP. This is important to represent in BPMN.
    * More detail could be represented later using subprocesses or
      exceptions.  Further detail can be added later or be visualized in
      a tool (such as more detail in the BTA such as for Catalog
      Request). Explicitly state that compensation should not be used
      when modeling ebBP in BPMN.
    * Discussed question if one process executing with different roles
      or different processes that have different roles.
    * Miers has seen one major end user, interaction with two parties in
      a collaboration (state alignment but no message being sent).

Open items

    * How to handle how roles changes with the relationships and behavior.
    * Need to understand more about the compositional aspects related to
      BTA, CA, and BC/MPC. Earlier this summer, BPMN considered the
      creation of a new activity (joint activity) that had unique
      characteristics. Would these conditions support the addition of
      such a new activity?
