As we agreed in the meeting, I am listing the problems in section 4 that I think we have to fix before releasing the standard. (BTW, this stack of messages contains the extract from the RAF that I initially commented - for references).
1. Orchestration and Choreography may not be confronted because they are two sides of the same composability. Orchestration uses choreography and vise verse. There are several places where this issue comes up and I have written version of changes.
2. Two terms coined by Boomberg and Newcomer several years ago do not make sense any more: "Service-Oriented Business Process" and "Service-Oriented Business Collaboration". Both expressions are tautologies - all Business Collaborations and processes are service-oriented, there are no non-service-oriented collaborations and processes in the business by definition. Many SOA architects say this now (but not 1-2 years ago). The wording has to be changed (e.g. w/o 'Service-Oriented' prefix) to avoid people laughing at us.
3. The diagram illustrating choreography on Figure 46 (as I reported before) violates basic business practice and may not be recommended in the standard. Internal business processes may not be integrated between different organisations, only external ones may be and, in all cases, via appropriate interfaces. This is what I have drawn in the diagram I circulated before.
4. Since SOA is positioned between business and technology, we have to be very accurate with out 'technical customs'. Particularly, business collaboration may be perfectly done via orchestration, not only via choreography. So, segregating orchestration (for the business process only) and choreography (for the business collaboration only) is incorrect and very dangerous from the methodology perspective.
As I said already, I do not only propose to reconsider the issues but I have written all texts for the reviews.
Regards,
- Michael

Gentlemen,
I have attached my proposals and comments for the section 4 ( and one - for the section 3) related to choreography-orchestration. It is a large document (13 pages) that includes original text and embedded changes.
Please, consider it as a draft/strawman.
Regards,
- Michael Poulin
