Here's the follow-up message from Ravi regarding my presentation on WS-Agreement on the OGSA telecon. yesterday. I think the discussion went very well, and we're perhaps poised to interact more with them in EMS in the immediate future, and perhaps in other design teams in the future. --- Jim -------- Original Message -------- Subject: RE: EMS session agenda (Re: Proposed agenda for Sept. 7th call) Date: Wed, 7 Sep 2005 17:35:55 -0700 From: Subramaniam, Ravi To: Jim Pruyne , Hiro Kishimoto , Ogsa-Wg CC: Andrew Grimshaw , Milojicic, Dejan , Stuart Schaefer , Michael Behrens , Nakata Toshi Hi, Here is a synopsis of the agreed next steps from today's OGSA telephone meeting. Attendees, please review and update as required. GRAAP: Jim: Thanks again for the introduction to WS-Agreement today. We appreciate your taking time to engage. I would like to reiterate the couple of areas of focus we had discussed at the F2F a. Understand the domain terms that may apply in agreements in a specific EMS scenario (BES?) b. Look at how one might apply WS-Agreement to the multi-entity (for a single operation) scenario that is EMS. (Cluster girds have a single entity (scheduler?) to handle all resources and requests and so that could fit the two party model of WS-Agreement but I was thinking of EMS outside of this space where responsibility is distributed). CDDLM: Dejan/Stuart: Thanks for attending this session. Sorry for any mixup here. I hope you did get something useful from Jim's presentation. Based on our discussions around CDDLM, here is what I captured: a. Hiro will send out the pointers to the interaction of EMS services for the 3 scenarios that was developed at the last OGSA F2F. b. Stuart will take a look and see how the CDDLM architecture would address these scenarios and start and email thread in the OGSA mail list. c. Ravi would collect any difficult or long drawn discussion topics (as suggested by the respondents) as agenda items for discussion at the next OGSA telecom. d. The OGSA WG will study the high level scenarios from CDDLM that were the model for the CDDLM specs. Need to reconcile these into the EMS/OGSA space. We will *not* have a parallel small team meeting this week but will schedule over the longer term (beyond GGF15) to do so as an ongoing activity as we work to resolve the approaches. Speaking for myself right now: I would suggest that an output of this activity be the OGSA EMS diagram fleshed out with the provisioning services from CDDLM (this could be either a blowing up of the provisioning box or a refactoring that may be dictated by this joint activity). Thoughts? OGSA: Anyone on the call today, please let me know if I have missed any of the outcomes of the discussion here. Any other suggestions and topics for discussions and/or focus with CDDLM and GRAAP are welcome. Thanks! Ravi
