RE: "Orchestration" and "Choreography"

Hi Sanjiva,
I quickly checked Chapter 13, Future Directions, but I don't see any
reference to future work on a global model.

If I missed it, please let me know where it talks about it. This is
important to understand BPEL's future direction.

Thank you,
Ugo

No! They represent in some sense the projection of a global
model to one partner. That is, effectively the public
process or interface of the service in terms of order of
execution etc..

I believe global models work is listed in the BPEL doc
as future work, but I may be mistaken.
