Subject: [ebxml-bp] BPSS evolutionhi:here is a list of possible directions to evolve ebXML BPSS:1. Control flow: 1.01 / 1.1 BPSS control is based on modified UML activity diagram semantics. This is a bit limiting and UML is changing these semantics in UML 2.0a. we could liaise with ws-chor and see if we could reference a ws-chor definition for a business transaction, binary and multiparty collaboration definitions.b. we could look at the work of Will Van Der Aalst if liaison with ws-chor is not possible2. Business Transactions: 1.01 / 1.1 BPSS BT Message Exchange Pattern is not general enoughWe could extend the definition of BT (or other concepts) via different MEPs3. Business Transaction Protocol: 1.01/1.1 Embedded in the BPSS speca. we could liaise with ws-caf or other relevant BTP groups and specify their usage in the context of BPSS rather than4. Specify a WSDL binding for the BSI: 1.01/1.1 currently no work has been done in this direction.5. Allow for a mixed mode: business transaction / web service within a collaboration definition.6. Orchestration / Choreography / Collaboration architecture and bindingsToday there is still a lot of confusion on these concepts. We need to provide a better picture on how these concepts play together in a common architecture.7. I have a few more but I would like for other to propose themIt would be good also if we could surface the issue of web services alignement to all ebXML working groups.Best regards,Jean-Jacques Dubray
