Subject: Comment: Section 2.1.1 Service Composition
SECTION: 2.1.1 Service
Composition
LINE: 202
TEXT: "When
implementing, more complex patterns of service invocation can be facilitated
while keeping these three axioms. If a transaction sequence is needed, a service
interface can offer two services - a put() and a commit()."
COMMENT: In the second sentence above, we appear to venture into the territory of transactional processing for SOA, and then we seem to treat it very lightly in the same sentence - i.e. all you need to do is offer these 2 services as part of a service interface (please note the slight exaggeration here to emphasize the point). Transactional processing for SOA is a very complex issue that is being addressed by multiple specifications/standards, one of which (WS-CAF) has 3 specifications or "levels" to it. Recommend that we either include a section/subsection for "Transactional Processing for SOA" if we believe it is within our scope, or state that it is a complex issue that is out of scope for the RM. If the former, I would be very happy to write this section.
