The meeting consisted primarily of an overview of proposed  
organizational/preparational tasks, listed below with responsible  
parties

Getting Contact Information for all groups (Chris will get from Hiro,  
Dona will maintain future list)

Getting new document list for inclusion in next Roadmap document  
(Chris will discuss with Hiro, Jem, and OGSA-WG)

Chris feels that section 1 needs to be rewritten to provide a more  
general motivation, as the current version focuses on follow-on  
activities to the release of the OGSA 1.0 Architecture document. One  
proposed addition/replacement for this section is a more detailed  
history of the GGF/OGSA efforts, and their relationship to other  
ongoing Grid Services standards work. (Chris has agreed to begin work  
on this)

Chris: The areas of section 2 regarding "OGSA process and  
compliance", and the ability of implementations to claim various  
levels of OGSA-conformance seems to need re-examination or  
clarification - It is not clear to the editing team how a "compliance  
test" for some of the involved standards documents would be  
implemented, and the number of levels of conformance seems overly  
complex. It is also not clear how the various levels relate to the  
ability of implementations to interoperate. Also need clarification  
on OGSA process discussion. (It was suggested that the process and  
compliance material might be best placed in a related but separate  
document. This topic has been deferred for later discussion, ideally  
with Hiro, Jem, and possibly the entire group)

All participants agreed that the document should include at least a  
more detailed summary of lower-level standards which OGSA and related  
documents build upon or assume some implementation of (I.E. XML,  
Schemas, WSDL, WSRF, etc), without including detailed tracking  
information for each of these standards.
(Mike Behrens will work on gathering status and relationship  
information for Web services standards. The OGSA community is  
actively encouraged to submit individual visions of the software/ 
standards stack)

Mike Behrens suggested that it would be helpful to include a new  
section on the future vision of OGSA and how that fits within the  
overall grid computing landscape. What documents have been proposed,  
and what are needed?

The above topic relates to Gap Analysis, a topic which was deferred  
for later discussion, once we have a better sense of how the new  
version of the document will take shape.

Open Items:

The overall vision for the roadmap, and the new documents to be  
included, probably need to be discussed in an official forum - Chris  
will propose to Hiro either a session at the OGSA F2F in July, or a  
discussion on one of the weekly conference calls, to try and get some  
feedback from the group on both topics.

We still need to reformat the data in the spreadsheet into a  
relational database or other, more manageable form - it was generally  
agreed that the current status spreadsheet is frightening, at best.  
We may need a shared web-space backended by a relational database to  
manage both the project and the technical data involved. it is  
possible that R2AD may be able to host this space, if GridForge is  
determined to be inadequate to the needs of the project.

The final item is the question of whether a call should be held this  
wednesday - Chris will be on travel next week, so will be available  
this week, then unavailable  until the last week of june. If Hiro and  
Jem are available to discuss some of the open items and topics listed  
above, I believe a call could be useful. Otherwise, I propose we  
stick to e-mail and schedule the next call for Wednesday, June 28th.

Thanks to all the participants. Comments and questions are welcome.
