Definition of "data set"
by Dave Berry 21 Jun '06

21 Jun '06

The glossary in the OGSA Data Architecture document currently defines "data set" as: "An encoding of data in a syntax suitable for externalisation outside of a data service, for example communication to/from a data service. Examples include a WebRowSet encoding of an SQL query result set, a JPEG encoded byte array, and a ZIP encoded byte array of a set of files." Is this correct? I'm not convinced that we use the term consistently to mean this - sometimes we just seem to mean a defined set of data items on a resource. We may need to check each occurrence of the term (there aren't too many). Best wishes, Dave Berry Deputy Director, Research & E-infrastructure Development National e-Science Centre, 15 South College Street Edinburgh, EH8 9AA +44 131 651 4039

New version of Arch document
by Dave Berry 21 Jun '06

21 Jun '06

All, I've put a new version of the architecture document on GridForge at https://forge.gridforum.org/sf/docman/do/downloadDocument/projects.ogsa- d-wg/docman.root.working_drafts/doc13621/1. This version addresses most of the issues raised by our recent review. I've also attempted to address the issues raised by some of the comments in the document itself - see the attached text file. I would appreciate any feedback on these changes (especially with regard to whether I can now delete the relevant comments). The changes in this version are primarily in the introductory and background sections. I still want to do more work on the technical sections, in particular spending more time on the interface outlines. Best wishes, Dave Berry Deputy Director, Research & E-infrastructure Development National e-Science Centre, 15 South College Street Edinburgh, EH8 9AA +44 131 651 4039

RE: [ogsa-d-wg] June 14th telcon - data scenarios v0.13
by Stephen Davey 13 Jun '06

13 Jun '06

Hi, In preparation for the review of the data scenarios document tomorrow I have attached the latest version v0.13. I'll try to put this version on GridForge as well. It contains the Data Provenance Scenario & Grid File System Scenario, but these are currently work in progress. At present v0.13 does not include any updates based on the comments sent recently by Allen and Mario. But we can discuss these during the telcon.

RE: [ogsa-d-wg] June 14th telcon - comments on scenarios
by Stephen Davey 13 Jun '06

13 Jun '06

Hi again, For reference I have attached the comments made on versions v0.11 & v0.12 by Allen and Mario respectively. Version v0.13 hasn't changed that much recently, just the addition of 2 new scenarios, so all the comments should still be relevant.

FW: Data Provenance Scenario
by Stephen Davey 07 Jun '06

07 Jun '06

The current Provenance scenario is included in the attached doc - still work in progress though. Cheers, Stephen. -------------------------- Stephen Davey, National e-Science Centre, Edinburgh, UK. -----Original Message----- From: Luc Moreau [mailto:L.Moreau@ecs.soton.ac.uk] Sent: 25 May 2006 12:35 To: Stephen Davey Subject: Re: Data Provenance Scenario Stephen, I reads nicely. I added a section to introduce the notion of provenance store, which can be implemented by 1 or more provenance services. I also suggested a scenario for the multiple store configuration. Is this suitable? It may have to be reformatted according to the style of the rest of the document. Do you have enough material to complete the example of interfaces? Currently, there is no discussion of security? Do you want me to write a paragraph of the security issues we're facing in the second scenario?
