Andrew:

There is also the option of not doing anything: i.e., assume that people will use many different systems (BPEL, certainly, but many others), and just make sure that OGSA addresses what is needed for them to operate.

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.

Andrew,

    
Steve McGough and I were asked to prepare a discussion around workflow
for the telecom tomorrow. Attached is a short slide deck and some XML
examples - to be explained during the call.
      
My apologies - I will not be able to join the call today. From the
slides it appears that we are talking about doing a new workflow
language.

This is fine in the spirit of doing a clean room analysis of
requirements but I am very concerned that OGSA does not look at
developing any new specifications until it has determined why existing
established specifications (and their various extensibility options) are
not viable.

Steven
