Closing OGSA-Data WG
by David E Martin 30 Apr '08

30 Apr '08

The OGSA-Data WG has done excellent work, both in leading a broad review of the Data Area and in producing the OGSA Data Architecture document which becomes part of the OGSA canon. The architecture document completes the major work item of the OGSA-Data WG. OGF groups are expected to close when their work is finished, so Erwin and I propose closing OGSA-Data and thanking the group for a job well done. Unless there is a strong consensus to extend the OGSA-Data WG, we will close it before OGF23. David E.

New co-chairs sought
by Dave Berry 21 Feb '08

21 Feb '08

Dear members of the OGSA Data WG, Both Allen and I are having to step down as co-chairs of the working group, in response to other demands from our day jobs. We have both enjoyed chairing this group and have found the work to be very rewarding. We are proud of the group's achievements; not only the OGSA Data Architecture document but also working with other working groups and encouraging the creation of new groups such as OGSA ByteIO and OGSA DMI. There are plenty of challenges left in the design of a grid data architecture and we would be delighted if someone would step up and lead the group from here. Mario will be leading a session at OGF22 next week to discuss the future of the group and the work that remains. Allen, Mario and I have written a short memo that summarises the key technical areas that we think need to be addressed with regard to data management services in OGSA. You can find this note on the group's space on GridForge - http://forge.ogf.org/sf/docman/do/viewDocument/projects.ogsa-d-wg/docman.ro…. <http://forge.ogf.org/sf/docman/do/viewDocument/projects.ogsa-d-wg/docman.ro…> This memo is our personal opinions; it has not been reviewed by the group at large and hence is not an official product of the working group. It remains for us to thank all of you for contributing in many ways over the years. It has been a joy to work with you and we wish the group every success in the future. Best wishes, Dave.

Final public comments addressed
by Dave Berry 12 Nov '07

12 Nov '07

I've just uploaded a new working draft of the OGSA Data Architecture that addresses the public comments from Jens Jensen. I've also added some more text to the Scope section, to properly set expectations. I believe this means we have addressed all the public comments. Hurrah! We have to update the reference given for the Scenarios document and consider how to reference v1.6 of the OGSA Glossary. I'll ask the OGF editor for advice on these points. Other than that, I think we're done. (Oh, and we have to reply to the artefacts in the public comments tracker, but that's straightforward).

Data Architecture Document Updated
by Allen Luniewski 06 Nov '07

06 Nov '07

I have uploaded a new version of the OGSA Data Architecture document to Grid Forge. This version: 1. Addresses typographical errors noted in Public Comment feedback from Clive & Krasimira 2. Adds an "Information Service" section per Hiro I also took a look at the opening and closing sections to see if I saw an inconsistency in objective for the document (this was a comment received at OGF 21). I saw none. Mario - the Data Access section has a number of uses of MUST and MAY. These are normative and probably should be changed. Please look at them and see if we can do something as simple as lower casing these without losing value. Dave has the write lock per our last teleconference.

by Allen Luniewski 22 Oct '07

22 Oct '07

The OGSA Data Architecture architecture document is nearing the end of its 30 day public comment period. Please take a look at it and submit your comments, even if it is little more than "I read it". You can make public comments at http://forge.gridforum.org/sf/discussion/do/listTopics/projects.ggf-editor/… . You have to be logged in to be able to leave comments. Thanks.

OGSA-DAI workshop at OGF21
by Mario Antonioletti 12 Oct '07

12 Oct '07

Hi, Apologies if you receive this multiple time. This originates from Richard Sinnott the OGSA-DAI User Group chair. ................. Dear All, I am putting a workshop at OGF21 together which you may wish to attend. The basic idea is to consider the complete spectrum of data work across OGF, from the higher level vision being defined by the OGSA data architecture group; the data standards being produced such as DAIS and ByteIO; the technologies realising these standards such as OGSA-DAIv3 and then to the end user developers trying to building applications with these technologies. Think of it as microcosm of OGF as a whole. This workshop will take place at OGF21 in the Leonesa-1 room on Tuesday from 3-4.30pm. The agenda for the workshop is: 3pm INTRODUCTION - Richard Sinnott (NeSC Glasgow) 3.05pm The BIG PICTURE::OGSA Data architecture in a nutshell - Allan Luniewski (IBM) 3.25pm THE STANDARDS::OGSA Data standards (DAIS/ByteIO) - Ally Hume (EPCC) 3.45pm THE DEVELOPERS::Applying OGSA-DAIv3 in the Clinical Domain - A.Stell (NeSC Glasgow) 4.0pm WRAP UP/DISCUSSION 4.30pm CLOSE If like me you get a little lost in how OGF the different activities hang together, the idea behind this workshop is to provide a snapshot of what is going on and a reality check of the work in the data area. Rich -- Professor Richard O. Sinnott Technical Director National e-Science Centre University of Glasgow, Glasgow G12 8QQ Tel: +44-(0)141-330-8606 Fax: -8625 Mob: 0795-2376627 Email: r.sinnott(a)nesc.gla.ac.uk
