I am not a great fan of OGSA even a lot of its activities are excellent. See http://grids.ucs.indiana.edu/ptliupages/presentations/GGF17OGSAMay10-06.ppt However I don't see we can come to any conclusion from TSC other than OGSA unless we change initial or boundary conditions of our discussions in a drastic fashion from those that led to OGSA.

Chris:
I find this exchange very useful (and interesting). With respect to the two paragraphs below, *my* opinion is that the two goals:
a) "build real operational grids using OGSA based components" and b) "produce crisp definitions that lead to implementations in the next 12-18 months"
are [or should be] semantically equivalent. However, clearly, not every one sees things this way.
Clearly we should spend some time on these issues of terminology.
But our main focus must be (I would assert) the question of how we achieve (b)--what definitions can we reasonably produce in that time frame, *that people will implement*? I emphasize the latter, because my view is that the difficulty is not the supply side, it's the demand side--we can produce specs quickly, but we need vendors who are prepared to embrace standards.
We can talk more tomorrow.

I don't think it's an issue of web services vs. not web services. It's an issue of crisp definitions that lead to implementations in the next 12-18 months. That's what I hear the board, and thus presumably the members, asking for.
And I'll say it again: setting a goal to build real operational grids using OGSA based components is not a valuable strategic goal for OGF. Not that OGSA is bad ... but OGF doesn't exist solely for OGSA. Statements along these lines lead to the impression that OGSA is a "boil the ocean" solution.
