Dear All,

     The Open Grid Services Architecture paper noted below give a
roadmap for Globus and the Grid, which is useful in longer-term
planning.

            Cheers, Tony

Subject: Open Grid Services Architecture paper


The  Open Grid Services Architecture paper has just showed up
in a public venue.

This paper has important implication for the architecture discussions,
and should be read by everyone in the GPA WG.

However, for the upcoming meeting I would like to focus on the
initial "Anatomy" paper so that we can establish consensus on the
lower level structure and nomenclature.

Bill

Dear All:

As some of you know, we in the Globus project have been hard at work for
some time, in collaboration with colleagues at IBM, studying how Globus and
Web services concepts and technologies can be combined to mutual benefit.
The name we are using for the result is "Open Grid Services Architecture"
(OGSA).

We've recently produced a first document laying out our ideas, which I am
referencing here ( http://www.globus.org/research/papers/ogsa.pdf ) in the
hope of getting feedback. A draft of a first more detailed technical
specification will be available in a few days; both documents are intended
as input to an OGSA BOF at the GGF meeting in Toronto in a few weeks. Our goal
is to establish a GGF Working Group as a forum for future development of
these ideas. If this GGF WG is approved, we will then use the GGF web site
to maintain the various technical specifications.

Work has already started on a prototype OGSA-compatible Globus Toolkit
implementation (Steve Tuecke gave a nice demo at last week's Globus
tutorials, thanks to excellent work by Thomas Sandholm, Jarek Gawor, and
John Bresnahan), and IBM has committed significant support that will allow
us to ramp up this effort. The web page  http://www.globus.org/ogsa/  has
details
on the goals and progress of this work.

We're very excited by progress to date and the future potential. Our
thoughts on how these new directions will feed into Globus Toolkit
development to produce Globus Toolkit v3.0 are summarized at
http://www.globus.org/toolkit/future-plans.html. Some important points: (1)
the development is evolutionary and builds on current Globus Toolkit
technology; (2) these are long-range plans that will probably not produce
significant released software until at least the end of 2002; and (3) we
are committed to backward compatibility and an orderly transition plan,
based on feedback from our users. We are also hoping to see significant
industrial effort applied towards the realization of these ideas within
complementary open source and commercial products.

Please do send us your comments, questions, and thoughts.

Regards -- Ian (on behalf of the Globus Project and OGSA team).

(The OGSA design team has so far consisted of Steve Tuecke and myself at
ANL, Carl Kesselman and Karl Czajkowski at ISI, and Jeff Frey, Steve
Graham, and Jeff Nick at IBM. Others are getting involved as we move forward.)
