OGSA Teleconference - 27 April 2006
===================================
* Participants
Jay Unger (IBM)
Jem Treadwell (HP)
Ellen Stokes (IBM)
Dave Snelling (Fujitsu)
Andreas Savva (Fujitsu)
Joel Replogle (GGF)
Steven Newhouse (OMII)
Mark Morgan (UVa)
Fred Maciel (Hitachi)
Hiro Kishimoto (Fujitsu)
Minutes: Andreas Savva
* Summary of new actions
ACTION: Ellen will do an example of a cluster (e.g., the glue
cluster model) and the 'red' to 'blue' mapping for it
ACTION: Hiro/Dave S/Jay/Ellen/... to talk offline and make a
proposal for a summer meeting location and time, possibly
in mid-July.
* April 24 minutes (draft 2) approved with no changes
* Webcast recap
Webcast went well and a recording will be posted in due
course. There were some dial-in issues and these may explain why
there was no voice Q&A. A number of questions were submitted through
the online system. A good percentage of registered people turned up
and Jem's impression is that most were new to OGSA.
Jay mentioned that sometimes people register just so that they can
get an update email later for the recording. One idea is not to
state in advance that a recording will be available later.
Also people may not eventually turn up due to the inconvenient time
slot. Doing webcasts in two parts may help against the inconvenient
time slot problem. For example, do just the explanation and post the
recording. And then arrange for multiple Q&A sessions at different
times convenient to different time zones.
The group produced a good slide deck and it is expected that it can
be used for other occasions. For example, Hiro is planning his
keynote off this deck.
Mark Linesch also attended.
Thanks to all who took part and especially to Jem for pulling
everything together despite the tight schedule.
* Action review
[Only updated actions shown here.]
- Steven Newhouse to ask Jennifer Schopf on the status of the GIN
modeling document.
There is no such document; delete action. (Done)
- Ellen will do a revised visio diagram that has only the relevant
BES attributes and JSDL attributes (base it off the
info_model_for_BES/BES Container class)
It is today's agenda. File (pdf) has been uploaded.
- Hiro asked Ellen to also upload the Visio file to gridforge.
- Andreas will sent information to Ellen on how to attach a file
(e.g., visio) to a pdf file to simplify uploading to
gridforge. (Done)
- Andreas: to finalize OGSA WSRF BP 1.0 doc and make a final call
- An updated draft is available and should be made public within a
few days.
* GGF17 session review
** Keynote
- Hiro is planning to base his keynote on the webcast material
after removing basic stuff and merging some slides into
transitions.
** Information model
- Discuss capabilities and requirements and their relation,
including position papers.
** EMS session
- Andreas has confirmed that NAREGI (beta) is not using
WS-Agreement.
- Steven N will produce a new version of the Scenarios document by
GGF17.
** Session scheduling
- Steven Newhouse has conflicts with both OGSA sessions. The group
discussed re-scheduling options, including swapping times with
other groups.
- One session (EMS) was moved to Wednesday at 5:45 and the other
(Information Model) to Friday at 1:45. There is now a conflict
with RSS-WG and Joel will offer them one of the vacated OGSA
slots on Thursday.
** OGSA F2F update
Discussed options for OGSA F2F during the summer. Previously the
group had agreed on two meetings: end of June and end of August. In
this call there was no consensus for two meetings during the
summer. Instead it was agreed to have a single meeting mid-July.
ACTION: Hiro/Dave S/Jay/Ellen/... to talk offline and make a
proposal for a summer meeting location and time, possibly
in mid-July.
* Information model discussion
Using the material sent out by Ellen.

** Slide 2
The abstract model (in blue) is intended to be much simpler than
the instance model (red). It is a list of capabilities of the
container, probably described as <name, value> pairs. For example:
<name = operatingsystem, value = redhat>
and so on
There was agremeent that it is desirable for resource capabilities
(blue) and activity requirements (green) to have the same language
(symmetrical rendering) and that the simple model (blue) should be
generated and updated (automatically by algorithms) from the
detailed model (red).
The main unresolved difference is whether extensibility should be
done using xml extensibility (as envisaged by JSDL) or by defining
some xml (typeless) element that can express 'something' as a
capability. One example to highlight this difference is
<OperatingSystem> RedHat </OperatingSystem>
versus
<capability name=OperatingSystem value=RedHat>
It was agreed to table the rendering issue for now.
** Slide 3
- The concrete CIM 'stuff' gets mapped into the 'aggregated' BES
abstract stuff
- Note the duality of jsdl 'execution requirements': as both job
requirements and container capabilities.
** Slide 4
ACTION: Ellen will do an example of a cluster (e.g., the glue
cluster model) and the 'red' to 'blue' mapping for it
This is a final call for re-submitting a revised version of the OGSA
WSRF BP 1.0 to the GGF Editor.
Please review draft 46 (changes accepted) or draft 45 (change-tracked
version) and send your comments to the list until the end of business
Friday, May 5.
Background:
You may recall that the WSRF BP 1.0 finished its public comment last
December. A revised version was ready in January but it was agreed to
wait for the publication of OASIS Standard versions of the WSRF
specifications. This version uses the OASIS Standard WSRF
specifications; and was also updated to make the other referenced
specifications consistent (e.g., use the same version of WS-Addressing).
Draft 46:

Draft 45:

or

Thanks to all who reviewed versions leading up to this one and
especially to Vivian Li for checking the referenced specifications.
