GGF5 (July 2002) Meetings (2 sessions)
Minutes of the OGSI-WG Session
Global Grid Forum 5
22-23/July/2002
Session 1: Update, Status, and Planning
22/July/2002
15.00 - 16.30
Minute take: Frank Siebenlist
Steve Tuecke presented slides:
http://www.gridforum.org/ogsi-wg/minutes/2002-07-22_ggf5_update.pdf
The following items are discussion points related to these slides:
* Slide 11: A Timestamp for Distributed Computing
Steve explained that the "orphaned" spec was revitalized recently,
because of its importance for OGSI.
It is more generically useful than just for ogsi, which brought up the
question whether ogsi would be the appropriate place for this spec.
The agreed conclusion was that as long as there is not better place,
we'll keep it in the ogsi-wg.
* Slide 12: Grid Compliance Service
General agreement that defining a set of compliance tests could be
good for this group.
Steve Graham: Caution. Do a scoping exercise. How expensive will
this be? Not cheap to build something like this.
Brian Carpenter: There could be legal liability implication of
specifying "compliance".
Ian Foster: Argue strongly against thinking about compliance tests
that go into technical spec. Can have parallel efforts to do this,
but not in core group.
Maybe compliance specification is too much - maybe better
informational "best practices".
Look at the web services world and how they have their own
interoperability organization WS-Interoperability.
Steve Tuecke: Suggestion to put a more complete draft together by
people interested in this area, and revisit this matter later once we
have something more concrete to evaluate. Rob Baxter "volunteered" to
take the lead (that he already seemed to have).
Also need to ask guidance from GGF on the legal implications.
* Slide 13: Java OGSI Hosting Environment
Agreed by show of hands that it should be handled in a separate
working group.
* Slide 14: OGSA Security Document
Proposed and agreed to have its own ogsa-security working group.
(Also discussed at OGSA Roadmap BOF, and security area meeting.)
It won't collide with other security related WGs, like GSI and CP,
because the charter will be ogsa specific.
* Slide 15: Grid Service Primer
Need a document that includes motivations, approaches, decisions.
The intended audience is the service developers community.
It shouldn't be implementation specific, but more how the patterns,
like notification and factories, are applied.
Who will step up? Kate Keahey "volunteered"
May not need to be part of ogsi - but needs place to publish.
Leave it to the authors how they want to proceed and where they want
to publish.
* Secure Grid Naming Protocol
Andrew reminded us that SGNP was also posted to wg email list, and
should be discussed.
Discussion about whether naming is well enough addressed within the
WG? Should ogsi define just one naming scheme or should it be generic to
accommodate more flavors? The Handle system was mentioned as a
possible alternative.
Further discussion deferred to next ogsi-wg session.
* Need more time between new drafts and meetings for people to digest
There was a claim that GGF has a 14 day cut-off that should be adhered
to.
Steve: To my knowledge, there is no such rule, and I cannot find any
such rule in the GGF document process document. There is a
logistics-driven cutoff if you want documents printed for a GGF, but
that is not the issue here. I will follow-up with Charlie to get
clarification.
* Slide 22: Implementations of OGSI
1) Thomas Sandholm (ANL): Globus Toolkit OGSI Technology Preview
Thomas gave a short overview and status update.
The technology preview release will be the basis for next Globus
Toolkit (GT3)
2) David Snelling (Fujitsu): Unicore OGSI Demonstrator
Unicore complex batch job workflow. (www.unicore.org)
Move on top of Webservices (wrapped Unicore servlet
implementations)
Totally parallel effort. No shared code with #1.
* Slide 24: Working Group Chair
Co-chair Jeff Frey...
