Fw: Srawman Architecture Document V.5 Uploaded to GridForge
by Allen Luniewski 31 May '05

31 May '05

I have updated the V.5 version with a new Storage chapter courtesy of Peter Kunszt: /projects/ogsa-d-wg/document/Strawman-Architecture_V.5/en/2 Barring emergency changes, I do not intend to update the document again before GGF-14. We should use this version of the strawman architecture document as the basis for discussion, comment and changes in our interactions on this DL and in our teleconferences for the next month. After GGF-14 we should start incorporating changes leading to the next major version of the architecture.

OGSA-D telcon schedule & preparatory work
by Dave Berry 30 May '05

30 May '05

Dear all, At last week's f2f meeting we decided the following timetable for OGSA-D telcons until GGF14. For some of these we are requesting participants to prepare material in advance - most notably, at next week's telcon we will be discussing security requirements for data grids and it would be very useful if you could circulate your thoughts beforehand. We plan to collect these requirements and present them to the OGSA security design team and other interested parties. * Topics June 1st: No telcon this week. June 8th: 1. Security requirements for data grids; participants to circulate notes in advance 2. Overall architecture June 15th: To be decided June 22nd: 1. GGF preparation; speakers to have draft slides ready for review 2. Data transfer June 29th: GGF14 (therefore no telcon) Dave Berry Research Manager, National e-Science Centre 15 South College St., Edinburgh Tel: +44 131 6514039

The Bigger Picture.
by Mario Antonioletti 23 May '05

23 May '05

Hi, I think one thing that has been lacking a bit in the OGSA-D WG so far has been the bigger picture trying to tie some of the concepts together. A long time ago I remember seeing the concept maps that were produced for the WS architecture (see: http://www.w3.org/TR/ws-arch/) and I quite liked these. I don't know what tool they used but I found something similar, if not the same. See: http://cmap.ihmc.us/ It's a java application and I think, though I've not looked too closely, is free. I have tried to create a concept map for the data architecture and have included an exported image as an attachment to this email as well as the cmap file that contains the source to the diagram in case anyone wants to play with it. It was very easy to generate and change and I believe the cmaps can be shared so they could be developed in a collaborative fashion. I think it helps to ellicit detail from the model, e.g. to what does the data description bind to: the virtualization or the service? Does the idea of having a data set defined in the data transfer make sense? i.e. I think of a data set as a disconnected piece of data that has been materialised outside the data resource and this would only make sense if it were staged. Do we benefit at all from making the distinction between a simple and aggregated data service? etc, etc, etc. Note that I am not advocating that these should be included in the document, nor that everything should go in one diagram (as is currently). I think that the diagrams can be nested (maybe). Is this a worthwhile thing to do? If the answer is yes can it be done so the diagrams are shared? Thoughts? I will try to distribute something on data access by the close of day today (UK time) albeit it'll be far from complete.

Draft agenda for next week's F2F
by Dave Berry 18 May '05

18 May '05

All, Please find attached a draft agenda for the F2F meeting on May 26th, based on the discussion in today's telcon. We can revise this agenda as necessary, either via e-mail beforehand or on the day. Please can the authors of each document section prepare a couple of slides for session 1? The idea of this session is to highlight issues that require input from the rest of the architecture, or that will affect the overall design.
