RE: [soa-rm-ra] rough non-UML orchestration and choreography figures

["Lublinsky, Boris" <boris.lublinsky@navteq.com>]

The more I am listening to this discussion the more I am getting confused. What are we actually trying to tell?

If I look at Ken’s picture, the only thing that I see is centralized vs distributed orchestration controller – implementation details, who cares. We said before that orchestration engine is an implementation approach, nothing else. So it can’t be distinguishing factor.

When I am looking at Mike’s picture, I am confused even more.

Here is a couple of suggestions:

·         There are two different types of business processes – sequential processes, the ones that was discussed all over the places, including BPEL and the ones that are defined as FSM (IBM and MS have implementations). Here the process is defined not in the terms of sequence of steps, but rather in the form of collection of states and states transition rules

·         There are two different types of service execution – complete and conversational. In the first case an execution is completely opaque, while conversational execution exposes its states that can impact further execution.

·         And finally we talked about message exchange vs execution sequence

So which one do we care about?

Here is my idea of 'choreography' diagram.

Specifics:
1) choreography does not need to be sequential
2) preiminary  off-line agreement is required from every participant
3) every participant generates its own RWE
4) messages are less important than interactions
