Subject: Negotiation in BPSS 2.0 format (Apri1 1 ebBP schema version)

Here is a validated instance of Negotiation that dispenses with using two BinaryCollaborations for modeling CPPA negotiation. Note that the CollaborationActivity references the BusinessCollaboration (new name for both Binary and MultiParty Collaborations) that it is in (after switching Roles—see the Performs element). An explicit CounterOffer document/envelope and other associated BTAs and BTs are no longer needed.

 

For Friday April 8 discussion.
