RE: [cddlm] CDL Spec

Hi, We had a very short meeting. Attendees: Guilherme, Satish, and Dejan. Updates: UFCG: no updates, same state as earlier, Ayla is keeping the portal alive and waiting for the feedback on their implementation. She did not receive any CDLs from component model in order to test against other portals (Stuart: when can we have them) NEC: Satish is preparing the code for open source, preparing it for SourceForge. Getting ready to attend GGF. At GGF, we'll have working sessions, no specific presentation, although if someone wants to give them, that is fine too. We'll have the meeting next week and we'll decide whether we should have meetings thereafter.

EGA & CDDLM comparison
by Hiro Kishimoto 24 Aug '06

24 Aug '06

Hi Dejan and Jun, OGSA-WG and EGA Reference Model WG have a dialogue on OGSA architecture and EGA reference model. Both parties are hoping to achieve beneficial synergy effects. Before creating possible reconciliation or resolution, both agreed to identify similarities and differences between our existing works. Minutes from Aug. 21 OGSA-WG call: https://forge.gridforum.org/sf/go/doc13750?nav=1 We think that EGA Ref Model's Dependency Graph and Life Cycle of Grid Components looks like very relevant to CDDLM-WG's work. http://www.gridalliance.org/en/WorkGroups/ReferenceModel.asp OGSA-WG will have a GGF18 session on Tuesday 4-5:30pm for this discussion. We would write up rough draft comparison slides before GGF18 and review them at this session. OGSA-WG GGF18 sessions: https://forge.gridforum.org/sf/go/wiki1560?nav=1 Dejan and Jun: Can you attend Sept. 12 (Tue) session in Washington D.C. in person? Can we work together to create first-cut draft slides of CDDLM & EGA Ref Model comparison? I've added this topic to upcoming Thursday's joint call. Thanks, ---- Hiro Kishimoto

Notes from the meeting on 8/23
by Milojicic, Dejan S (HP Labs) 23 Aug '06

23 Aug '06

Attendees: Flavio (UFCG), Satish (NEC), Stuart (Microsoft), Dejan (HP) UFCG: Keeping portal up and running, waiting for files from Stuart. Might be worthwhile pinging Stuart. NEC: Haven't made much progress in the last month or so, but right now Satish is trying to wrap-up the source code and put it on the sourceforge, that is pretty much what he was doing. Satish will attend the GGF, will inquire from Jun about the status of the CDL spec. Softricity: due to the move, had some problems with the component model spec, Steve helped with that. Will mail some updates to all. Example files were mentioned, but he can not make anything public. Inside of the component model there were some CDLs, these were all uploaded in the sourceforge, asked Flavio and Ayla should inquire by email details. GGF: Satish. Steve; Stuart & Dejan still planning to attend. Satish would like to know when do we need to put the code into the sourceforge. No guidance. More important that Jun finishes his document. It would be good if all of us attending GGF also attend the session on CDDLM and EGA that Hiro posted about. I have forwarded email to Satish and Stuart since Jun will not attend. Thanks, Dejan.

Notes from the

09 Aug '06

Attendees: Ayla, Jun, Stuart, and Dejan. Guilherme, Flavio, and Steve suggested that they will not be able to attend. Update: ----------- Ayla: completed the implementation and stopped at this point, what is missing is other CDLs for the component model. Nothing else planned for this week, Will do testing only on demand. Completed the documentation and uploaded. Stuart: on vacation this week, not too much from inside office. Did internal tests, but not much with other end-points. As of GGF, this group will discontinue, we need to wrap-up. Softricity is now part of MS, Stuart will help to close the group. Jun: refining the interoperability document for CDL, trying to find the time to complete the CDL document. Need next week to work on that. Washington: ------------------ Steve will attend, Dejan still plans to attend, as well as Stuart. Jun will not attend, Ayla, and Satish. OGSA --------- Jun is working with Hiro to create a profile for the POSIX component. Hiro is designing it using CDL and Jun is helping with questions. They have a joint group meeting. They are asking to help a formal document and then they will use it as a standard component. This will happen after completing 1.0 CDL and other documents. Have some suggestions for the extensions. They would want to access deployed CDL documents using Xquery, this is a good idea. Another idea is whether they can use ID and Xreference. For this kind of discussion, we should also address. Action items: Dejan will approach Steve Pickles. All will work on completing the interoperability documents. Jun will try to complete the CDL update before the next meeting. Stuart will approach others for the interoperability tests for component model. Thanks, Dejan. > _____________________________________________ > From: Milojicic, Dejan S (HP Labs) > Sent: Tuesday, August 08, 2006 10:50 PM > To: 'cddlm-wg(a)ggf.org' > Subject: Quick reminder about the regular meeting tomorrow > morning, 6am PST > > Hi Team, > > There will be our regular meeting tomorrow morning.
