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. Ian. Andrew Grimshaw wrote:
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.
