Subject: RE: [ebxml-dev] Reminder: ebXML BPSS 1.05 Public Review Period Ends 7Sept2002
As a contributor and author of the BPSS spec I have always felt that BP-SS is a misnomer. It should be called Business Collaboration Specification Schema as the purpose of the specification is to describe how 2 companies interacts with each other (and consequently how their business processes interact with one another). So to be clear BPSS does not overlap with the core of BPEL or BPML for that matter. Each of these specifications have something that covers "business process interoperability". In case of BPML it is a global model with the combination of WSCI interface definition. The way BPML/WSCI works is that you describe the choreography of the interface of the two parties and then you stitch together these interfaces via a global model, so if you want to get a feel for what the choreography of the collaboration is you have to keep going back and forth between the API choreography definitions and infer the sequence of message exchange that way !! BPEL uses the same semantics (except for a few limitations) to describe the "abstract process" which is the collaboration between two processes. Two web services representing the interfaces of the processes are related via a "service link" definition. Last but not least, I have create a business process definition language based on the semantics of ebXML BPSS which enables process definitions that combine both web services and ebXML business transactions. As a reminder, the concept of business transactions as a "packaged message exchange" is more general than the RPC like web services operations. This is why there is some value in defining a process that can deal with both.
