Gary Brown: Attached is a proposal for the replacement of the 'perform'
mechanism with a more flexible interaction based approach to
choreography composition. I would like to discuss this issue on the
earliest convenient conference call.
mm1: The conversation continues, on the 'perform' evaluation on
choreography composition. These questions and issues you raise touch on
my previous questions about our recognition of, visibility to, and
dependencies evident in choreography and sub-choreographies. We
discussed this in the F2F in Cannes where we only acknowledged the outer
not the inner box [1]. In your proposed solution, I have two questions:
* You bind the roles in the relationship between the inner and outer
choreographies. Therefore, if bound in a relationship over a
channel, the partner cannot change roles in the sub-choreography.
This would require a different composed choreography if the buyer
assumes another role in the inner (sub-)choreography correct?
* Payment Process and Goods Distribution are separate transactions
that relate to exchanges that may be bounded by business
agreements (thus separating fulfillment responsibilities). Can we
provide traceability and error functions when this compositional
capability occurs? Perhaps this will be discussed in Tony's
submission.
Thanks and I look forward to the discussion.
[1] I think we discussed blue and red boxes but I don't remember which
was inner or outer.
