Subject: [ebxml-dev] A Proposal for multi-party collaboration choreography,and an articulation between ebXML and web services


I have spent more time looking at WSCI, and specially focused on the
example (see figure 5-3) of the spec. It is pretty clear to me that the
combination of interface and global model definitions can be used to
describe a collaboration between components or applications within or
outside the enterprise.

I certainly find it cumbersome and risky to use the WSCI approach where
the interfaces can be designed independently of each other, therefore
making it difficult to be guaranteed that they are really compatible
with each other from a dynamic behavior perspective.

So what I have done is put on paper some ideas I had for quite some
time. For good reason, multi-party collaboration was introduced as a
synthesis of binary collaboration since trading agreement can and should
only/mostly be done between two parties. However, from a choreography
perspective that is not the best way to describe choreography between
various parties. 

I have taken a different approach which was the repurpose the
choreography specification of a binary collaboration into a multiparty
collaboration. This was needed to establish the articulation between
ebXML and web services as I think we should expect that a relationship
should either be ebXML or web services but not both (in the context of
the same collaboration). It would be odd otherwise to have a mixed
collaboration. So a typical example would need to involve at least 3

The important thing is that I have done only two minor modifications to
the BPSS spec to do that (no need to create a new spec for it!). We will
need some modification of the CPP/A spec if people want to go in this

I think that the Agent-N-Airline example of WSCI and WSFL can be well
represented with this new paradigm because it does not take any point of
view. It simply provides a way to express the flow of message between
any number of partners. From this perspective, interfaces can be
calculated automatically. 

I am preparing a follow up paper which uses the same approach
(multi-party collaboration) to express both executable and enterprise
business processes. One of the advantage is that the concept of B2B
collaboration is bolted into this new Business Process Definition
metamodel unlike previous ones. I plan to have this paper out by Friday.

As usual, comments, feedback, are more than appreciated.

The paper can be found at www.ebpml.org/ebpml.doc
More analysis on the WSCI example can be found at

If we the WSCI authors want to make their complete XML definition
available, I will detail the complete choreography expressed as ebXML
