No RM teleconference on the 27th
by Fred Maciel 27 Sep '05

27 Sep '05

Hi, No RM teleconference on the 27th -- nothing left to discuss from the teleconference today. Given that we are using the OGSA-WG teleconferences for discussions, I'll change this teleconference from "do by default" to "don't do by default" ("on demand" sounds more trendy... :-). So, from now on, if I don't announce the teleconference, it means that we are not having it. See you in Boston, Fred Maciel Hitachi America R&D

Information model profile doc for OGSA -- initial thoughts
by Fred Maciel 26 Sep '05

26 Sep '05

Hi all, I've been thinking of our guidance document on CIM profiles and how to represent them on the OGSA spec. I don't have any answers, but at least I got to the point where I have a lot of questions... :-) I'm hoping to have your opinion on them in Monday's teleconference. So, let's start. First of all, DMTF's document on how to write a profile has started a one-month review inside the DMTF, so all DMTF members should have access to it. The document is right on the top of the document review page: http://www.dmtf.org/members/review/ . It's still DMTF confidential so I can't post it here (sorry), but I'm taking into consideration since it should be publicly available in a month as a preliminary document. Meanwhile, the first slides of Andrea's presentation in the last face-to-face (see http://www-unix.gridforum.org/mail_archive/ogsa-wg/2005/08/msg00075.html ) are a good summary of the sections and contents in such a profile. The DMTF document gives all the details on how to specify a profile, includes a lot of experience (which allows us to avoid some pitfalls) and saves us a lot of time. However, I think that it's an overkill for individual OGSA specs (*), especially the ones that cover only one or two classes. So what I'm thinking for now is two levels: (1) We create an information model profile per OGSA area (Execution Management, Data, etc.), or, a profile for OGSA with sub-profiles for each area. These can be part of an OGSA profile (i.e., some of the OGSA profiles will include the corresponding information model profile). These profiles act as integration points between the pieces of the information models that each individual OGSA spec uses. The definition of these information model profiles follows the guidelines of the DMTF profile spec. (2) Individual specs show the information models they use in a lightweight way. The OGSA document on how to write an information model profile (we need a title and a nickname for it. Suggestions?) is a guideline on how to specify the information model on these specs. Notice that Cisco's modeling tool (about to become open-source) will be useful for both (1) and (2) above. It can even change the balance of things above in subtle ways depending on how (and how much) it makes the creation of a profile easier. That's all for now. Opinions please. Regards, Fred Maciel Hitachi America R&D (*) By "individual OGSA specs" I mean specs like ByteIO, OGSA-BES, etc., not the roadmap, profile definition, guideline specs, the OGSA spec itself, etc.

Teleconference minutes - 21 September 2005
by Andreas Savva 25 Sep '05

25 Sep '05

Minutes attached. https://forge.gridforum.org/projects/ogsa-wg/document/minutes-20050921/en -- Andreas Savva OGSA Teleconference - 21 September 2005 ======================================= * Participants Mike Behrens (R2AD, LLC) Hiro Kishimoto (Fujitsu) Allen Luniewski (IBM) Fred Maciel (Hitachi) Dejan Milojicic (HP) Andreas Savva (Fujitsu) Latha Srinivasan (HP) Ravi Subramaniam (Intel) Jem Treadwell (HP) Pete Ziu (Northrop Grumman) Jay Unger (IBM) Apologies: Ellen Stokes Minutes: Andreas Savva * Minutes approval - Sep 14 minutes approved with modifications. Hiro to correct. - Sep 21 minutes approval postponed for next week. * October F2F Update - Request to put Naming early on Thursday - Andrew has a conflicting session (Community track) - Agreed to schedule the naming session mid-morning - Proposal to start early Thursday the morning: - Agreed to start at 8:00am since many people plan to leave early. - From the survey so far more than 20 people are expected. Also some people (Fred, Jem) haven't completed the survey yet. - It was noted that many people are attending only some portions (mainly Thursday morning) so even if more than 20 people are on the list the IBM facility may be adequate. - Jay has a logistics document describing location and so on and will send it to Hiro. - Actions on Jay - Re-check the real room capacity (stated at ~20 people) - Reserve a projector - Jem volunteered to bring a projector if one is not available. Need advance notice - Check if there is a telephone line - Provide updated status by Monday - Hitachi (Fred) might be an alternative venue but it is further away. - Hiro will put together a complete agenda/logistics doc and send to the list. * Resource Metadata Editor discussion postponed (prefer to have Dave Snelling on the call for this discussion) * EMS - Agreed to postpone technical discussion (many key people missing) - Agreed (last call) that viewing a CDDLM demo would improve understanding of CDDLM functionality. This demo could be arranged a number of different ways: - On a CDDLM call (possibly adding Ayla's demo) - On an OGSA call (specifically for OGSA) - This Friday there is a demo from Softricity (CDDLM call) - CDDLM demo during GGF15 Prefer to do it on OGSA call. Dejan will ask Ayla to do demo on the OGSA call next week (Wed). - Ayla's slides are a good introduction. Dejan has forwarded a link to the OGSA list. But note that the presentation is likely to be updated before the next demo. - OGSA members are also welcome to join the CDDLM calls and view the other demos. For GGF15 the OGSA status session overlaps one of the CDDLM sessions. This OGSA session is a high-level oveview session and it is not essential for CDDLM members to attend. - The last GGF15 CDDLM session (Monday 6pm) is reserved for discussions with other groups (ACS, OGSA). - The second CDDLM session is for demos. - BES and CDDLM connection? - It should be explored in the context of EMS rather than just between CDDLM and BES. BES is focused on producing its own spec. - Stuart is working on refining Mike's sequence diagram and may have something by next call. * OGSA WSRF Basic Profile Review - Submission schedule - Initial plan called for waiting for the completion of the security profiles and their simultaneous submission with the WSRF BP. But the security profiles are likely to take some time---definitely cannot be ready by GGF15. - Agreed to (re-)submit BP first (Note BP was submitted a few months back and then placed in a temporary 'hold' state.) - Also agreed to try and speed up the basic security profiles in order to have a partially overlapping public comment period with the BP. - Exclude UDDI portion of WS-I BP 1.1 - There is no specific reference to UDDI in OGSA WSRF BP 1.0 (functionality is out of scope) but it is included by reference to BP 1.1. - Agreed that is should be explicitly excluded from the OGSA WSRF BP. - Discovery is important and should be covered somewhere; perhaps as a separate profile. But we cannot take a position on what the mechanisms are at this point. - Agreed to add a clarification to Hiro's proposed text to address the possible question of where discovery might be covered. - Has there been a complete review of BP 1.1 to make sure there are no other features that are being included by accident? - No. But Hiro is not aware of any other issues. - Agreed that such a review should be done but there is no reason to hold up the submission for this. The review can be done during public comment. The Authors/Contributors in particular should be encouraged to do this review. - Hiro will make the necessary change to the WSRF BP and do a final call on the list. The plan is to submit it to Greg by the end of this week.

RE: [ogsa-wg] OGSA WSRF BP 1.0 Editor submission final call
by Djaoui, A (Abdeslem) 24 Sep '05

Well, my point is that Discovery is fundamental in OGSA and MUST be (not MAY be) addressed by OGSA, especially now that UDDI is excluded from the base profile. But I agree that the plans and decisions are still to be discussed.

Thanks for the clarification David. Putting it another way UDDI can still be used, but a separate claim for conformance should reference WS_I basic profile rather ogsa-wsrf-basic-profile.

Ad-hoc BOF on Streams at GGF15
by Dave Berry 23 Sep '05

23 Sep '05

All, I apologise for cross-posting so widely; we are trying to reach people who are work with data streams in a Grid setting and there is no obvious single place to post. We are organising an ad-hoc BOF at GGF15 on the subject of data streams in Grid architectures. Our aim is to bring together people working on various aspects of data streams. Our personal goals are to determine how best to fit streams into the OGSA Data architecture but we also see this session as an opportunity for people to share experiences and meet others working in overlapping areas. The BOF will be from 6.00-7.30pm on Monday Oct. 3rd. The first half of the session will see presenters addressing some of the questions below. We will keep the second half of the session for discussion. Issues to consider: - What do we mean by a "data stream"? - Grids have to consider attributes such as security, persistence, and quality of service. Do these raise any particular questions for streams? - What are the important use cases? Are there unusual or non-obvious cases that we need to consider? - What is the natural programming model for streams in a distributed environment? - How do we connect one stream to another? - How do streams fit into a service-oriented architecture? - The OGSA Data Architecture currently has sections on Provisioning, Querying, Replication, Caching, etc. Do these apply to streams as well as static data? Are there any particular aspects of streams that affect any of these sections? We look forward to seeing you there.
