OGSA Teleconference - 20 July 2005 ================================== * Participants Mike Behrens (R2AD, LLC) Andrew Grimshaw (UVa) Hiro Kishimoto (Fujitsu) Fred Maciel (Hitachi) Mark Morgan (UVa) Takuya Mori (NEC) Andreas Savva (Fujitsu) Pete Ziu (Northrop Grumman) Apologies: Tom Maguire Minutes: Andreas Savva * Minutes July 18 minutes approved with minor modifications: date is wrong, and should be corrected to July 18. * F2F Update - The Resource Management (RM) design team wants a slot during the F2F; preferably a full day. - They had a call, starting their discussion from the same point as the last OGSA call: the need for a document to make requirements concrete. The F2F seems to be the best time to start working out the contents of this document. - Andrea Westerinen will also be joining the OGSA F2F for this purpose. (She cannot make it before Wednesday, however) - Andrew is also needed for this effort. But he is leaving Thursday afternoon. - Schedule proposal is to use the OGSA session Wednesday afternoon and continue in the OGSA session Thursday morning. - Will look at BES, and EMS resource model (RSS will need something too). - EGA joint-session is also being planned for Wednesday afternoon. - Andrew is therefore double-booked. - Agreed to move the EGA session to Tuesday morning, either in parallel to or after ByteIO if it finishes early. - The EGA members may want to get involved on a specific issue. The RM work seems like a good candidate. In this meeting however it may be better to discuss procedural issues. - And start discussing what that common topic is. Suggest RM as a candidate. (And possibly ask them to join the RM work at a later point when it has more structure.) - Is the OGSA general session on Friday sufficient? Not sure. - Are ByteIO and Naming taking too much time on the schedule? (half-a-day each) - ByteIO: a couple of hours are probably enough (including spec review). No controversy so far. - Naming: there seems to be (tentative) consensus on the main issues. So a couple of hours might be enough. This excludes a discussion of RNS. If RNS is discussed then half-a-day in total may be needed. Action: Andrew to send an email to the EGA members and arrange the meeting for Tuesday morning. Action: Andreas to book an extra room for Tuesday morning - Marvin Theimer cannot join in person. Add to the list of people dialling in. * Next Step discussion Based on Hiro's draft sent out before the call: http://www-unix.gridforum.org/mail_archive/ogsa-wg/2005/07/msg00064.html - OGSA-WG is already committed to the following activities: - OGSA 1.5 and Glossary 1.5 - OGSA Roadmap 1.0 - OGSA Profile definition (submitted; waiting to enter public comment) - WSRF BP 1.0 (working to complete; schedule has already slipped. Probably cannot publish before November.) - EMS area: - BES has already started and RSS is starting up. - CDDLM and ACS work has to be integrated (see next topic) - Provisioning - Priority is high; will be worked on at the next F2F in the joint session with CDDLM. - Basic EM Profile: revisit after GGF15 - Job Manager Interface: - Perceived overlap with BES as well as work from other groups. - Not high priority; revisit later. - EMS architecture document - As a separate document it may take longer than August. [Need to identify what changes in OGSA 1.5 though.] - Grid Resource model - This is now high priority; agreement is to start working on this soon. - Resource virtualization: This seems more of a by-product of OGSA work. Probably do not need it as a separate topic. - Information services: Abdeslem has indicated he needs help with this topic. Need to follow up with Abdeslem. (Not sure if he can attend the F2F. Hiro to confirm.) - OGSA Authz - They have submitted one document recently; it is probably going to public comment soon. - There is also another draft on using SAML and OGSI. It needs to be revised for WSRF. - They are trying to re-charter. - OGSA-WG would like to be more involved with this group. The target is to have the same level of interaction that OGSA-WG has with BES, RSS, etc. (Especially since this seems to be the only active security group and it carries the OGSA prefix.) - Therefore synchronizing with this group is high priority. The F2F may offer a good opportunity to do so. Maybe invite members of OGSA AuthZ to attend and have a discussion. - Some people are based in the Bay area. - Negotiate a place on the agenda based on their availability. Action: Takuya has contact with this group (OGSA liaison) and will invite them to attend. - Agreed to add Basic Profile 2.0 to the list. - BP 1.0 interop - this is going to be a lot of work. and noone has taken this activity on yet. Volunteers needed. - If it will happen in public at GGF16 it should be done before in a smaller circle. So as to make sure it will not fail. Action: Andrew will ask Marty if he would like to lead this activity on. - Roadmap document update - OGSA-WG has committed to updating this document. So it should be moved to the first section. - It is low priority. - Use case cross-check: low priority. No volunteers. - December F2F: consider La Jolla as a location. - Hiro's schedule proposal: - Andrew has sent out comments on RNS specification. Some time for the RNS review should be allocated in July/August - Roadmap public comment period is until July 29. - There are very few comments. Are those enough? - It is an informational document and so the bar is lower than Recommendation track. - Is there a way to check how many people have downloaded it? - All should try to invite more comments from colleagues. [An updated version of the work items list, based on this review, was sent to the list: http://www-unix.gridforum.org/mail_archive/ogsa-wg/2005/07/msg00068.html] * WSRF BP 1.0 review There has not been a separate security call or discussion yet. Also Takuya is still reviewing the WS-I Basic Security Profile (WS-I BSP) on the header signing issue. Other related issues are also still unresolved. Review based on draft 29: https://forge.gridforum.org/projects/ogsa-wg/document/draft-ggf-ogsa-wsrf-basic-profile/en/24 Did a page by page review until page 14 (l.493). Accepted all changes to that point with the following exceptions: - R0429: Takuya has comments on the Schema Centric Canonicalization specification. A summary follows: - The Schema Centric Canonicalication specification only covers serialization of nodesets. So there is still a need to define the schema for the content of reply messages when the return values that are strings, numbers, booleans. (XPath allows such return values.) - Even if selecting a fragment the whole document would be serialized; this might cause big performance problems with large documents, even if the returned fragment is small. Action: Takuya to send an email with his concerns on the Schema Centric Canonicalization to the list. - E0802: Is this extensibility point listed in WS-I BSP 1.0? - Takuya think it is. Action: Hiro to re-check the WS-I BSP 1.0 - A newer version of the WS-I BSP seems to be in the works. But there is no time to change from using the currently used version. Might be able to do so during public comment. - l.493: 'only' issue is still unresolved. Action: Takuya to propose new text to the list. * Other business - Andrew will miss the next call (Monday) due to other commitments.
