I don't think that this is the case. In fact, I think that usually, really
high-level services in OGSA will be Web services, while "lower level" stuff
(e.g., resources and their systems management) will be modeled as resources
(read: WSRF-based). Of course, there might be exceptions here and there.

You can find more details on this on the CMM-WG document (just approved as
GFD-45 today!), which is a "long" version of section 3.6 of the OGSA spec.
You can find the CMM-WG document in:

Try sections 3.2 and 5.1.

I found it quite interesting that the work on execution management
interfaces is going the WSRF way, not the Web services way -- I was
expecting the other way round. It seems that the entities they are modeling
are quite "low-level", while I was expecting a "very high-level" job
manager.

(Wait a minute. Does this all mean that I and Savas agree? What's wrong
here? ;-)

See ya,

Fred Maciel.
