Subject: BPM not in alignment


Anders :

I think we need to slot a specific time for discussion about the scope
of ebXML with respect to the marketplace discovery mechanism being
contemplated by BPM.  I don;t see it as possible to implement in phase
one of ebXML but the UML view model dictates it is an inherently
important part of the business process.

IMHO - it must be considered out of scope.  There are many alternative
efforts who already do this work (eCo comes to mind).  We should
definately not preclude any such process from "bolting" n tot he front
end of ebXML.  

Please do not confuse this with the business interface discovery
process.  This is of utmost importance to define.

I also think we need to earmark some time to specifically talk about the
process flow and how the syntax may represent contextual components at
run time.  IF a data component is appearing in two contexts,  there has
to be a mechanism to derive that information and pass it on.  

Scott Nieman has expressed some similar thoughts on this subject.
