[ogsa-wg] Materials for tomorrows call

[Andrew Grimshaw]

Steven,
I agree. If you look at the slide deck one of the "issues" is the large body
of existing work - much of it very good; and much of it more complete than
we would want to endorse (e.g., it comes complete with a GIU, security
model, ....) There is the further complication of choosing an existing
system - the political and market battles that might ensue. The question
before us is - 1) adopt something existing, or 2) gather best practices and
generate some sort of simple least common denominator a la JSDL, or 3) try
and design by committee a complete package.

I personally think (2) is the best choice :-). In any case there will need
to be much examining of what is there as well as requirements generation
(presumably from use cases.)

By the way we were NOT proposing the XML stuff we sent as a "standard" -
rather a sketch of the level of detail we might want to address.
