RE: more on collaborations, contracts and 2-27 minutes

Hope not to miss the point completely.... in which case I apologize.

 

The verification of the correct sequencing should be done by the middleware (the infamous BSI) which should be configured out of the content of the CPA (which, in turn, references the Collaboration choreography specified by the BP).

Subject: RE: more on collaborations, contracts and 2-27 minutes

Dave asks for confirmation that something in ebXML can tag and count messages sequentially, so as to enable crossreferencing, detection of blips arriving out of sequence, and the like:

 "I can understand that at a lower level TRP service, there's something dealing with 'message counting' but I'm not aware that something like this info finds it's way up the stack so the business app's can also do their counting; which does sound like redundant but it is the way of the world and as such it's not going to stop. "

In our "simple negotiation pattern" test, we also noted that messages need to be able to cross reference each other, and sought confirmation of some kind of unique message ID.

Good questions.  I don't know the answer.   Can we do that?   Goes on my list for tomorrow's metamodel meeting.   Jamie
