DAIS Telcon 09/11/04 ==================== Chair : Norman Paton Minutes: Mario Antonioletti Present: ------- Mario Antonioletti, EPCC Norman Paton, University of Manchester Simon Laws, IBM Leon Guzenda, Objectivity Susan Malaika, IBM Greg Riccardi, Florida State University Allen Luniewski, IBM Proposed Agenda: ---------------- 1. Contributing to the Naming Design Team 2. Contributing to the Data Design Team on Data Movement Actions: ------- [Norman] Email office@ggf.org to point that we have an on-going activity with CGS - hence we are surprised that this effort is listed as being closed. Cc relevant people in. [Simon] Wrap up the mappings document and submit it (pass on to Norman). To be done by the end of November. [Simon] Post a tracker and a proposal to go out to the dais-wg mailing list about the WSRF embodiments that could be adopted by DAIS to initiate a discussion. To be done by the 16th of Nov. [Susan] To post a reminder to the DAIS list about the OGSA naming effort/telcon and put a pointer to the WSRF embodiments document and hint that there is going be more discussion about this on the dais mailing list. [Norman] See if a new telcon number can be sorted out for future DAIS calls. [Susan] To report back on the currently open issues on the relational spec for the next telcon. [Amy] To report back on the currently open issues on the XML spec for the next telcon. [Simon] To report back on the currently open issues on the core spec for the next telcon. [Spec Team] Have a straw-man proposal on a top level operation for the next telcon. On-going Actions ---------------- [Dave P.] To draft and distribute a new version of the socialising document. [Susan] To email to Dave contacts in XQJ and XQuery groups. [Norman] Prompt Thomas regarding a posting to the list about the Object Data Access document. Thomas was prompted but nothing has appeared on the list as yet. Dead Actions ------------ [Norman] To recommend that Simon reports back at the next call. Simon reported back on this call. --- 1. Contributing to the Naming Design Team The OGSA naming people have had telcons but these are relatively late for UK.Awkward time for telcons for Europeans probably because of the times. May be due to the fact that they are trying to fit in Japan. Simon has done some stuff on naming for OGSA-DAI but not for DAIS. There have been a number of concerns: interaction of the naming with the infrastructure - the mapping; also how the naming interacts with the underlying data resource names. Need to see how DAIS can keep in touch with the OGSA naming effort and influence where appropriate. Could use the OGSA Data Design Team but this was thought to be too circuitous despite the fact that Andrew Grimshaw is also involved in this effort as well as leading the naming. The question was raised about releasing the OGSA-DAI naming document - however this does not have DAIS content so it may not add much. Susan pointed out that the naming people are having an OGSA face-to-face in the East Coast in December. Allen and Dave Berry are more involved in the naming scheme through the data design effort - can ask them to keep us informed of what is going on in that space. Simon will keep track of what is going on in the OGSA naming effort. Simon will also send the OGSA-DAI naming document to Dave Berry to inform him of what some of the data related issues are. The OGSA naming folks are having a telcon on the 15th of November. Susan will confirm details on the DAIS list. Allen will attend the call and will feedback anything of interest relating to DAIS. 3. Contributing to the Data Design Team on Data Movement Allen reports back that not much has happened. Simon adds that Andrew Grimshaw and Mark Morgan have come up with a context space and file access and some effort has been expanded on metadata. As yet no straw-man OGSA data architecture is in place. The intent for this item had originally been to discuss data movement in the context of such a document being available. However, it looks like everybody who's involved in this effort is too busy and no document has yet been produced. 4. Mappings document The intent is to try to move the mappings document to be a GGF informational document. Simon has been looking at the WSRF embodiments document following on from GGF12 - names or identities for data resources in services while being consistent with WSRF. One of the embodiments presented looks promising (number 4). This embodiment allows us to pass the identity in the body and in the header. The implementation then chooses which one to use. [ For the embodiments document see (aka WS-ResourceProperties document): http://docs.oasis-open.org/wsrf/2004/06/wsrf-WS-ResourceProperties-1.2-draft-04.pdf ] This embodiment should be presented as a possible solution. However, the mappings document should not be a proposals document. If we are in a position to make a proposal then this should be sent to the DAIS list or presented as a short document - this is a spec issue. The mapping documents should be wrapped up as a discussion document and then any proposal should be sent to the list. This also serves to give feedback to the WSRF group. Susan mentions that the WSRF group had explicitly asked for feedback. Simon will post feedback to the WSRF folks about the embodiments document - in particularly they wanted feedback on the fourth option. The WSRF folks want feedback asap. 5. Update on socialising Dave was supposed to draft an update - has not been done. The hope that Dave has been socialising at the Enterprise Grid Alliance. AOB --- Mario mentioned that a more permanent telcon number is required for DAIS - the old number retired with Brian Collins. Simon Laws had kindly provided his number for this meeting but this was a one off. Norman took an action on finding an alternative number. The proposed agenda for the next telcon: 1. Review known spec issues 2. Review a design for a top level access operation also try to 3. Discuss WSRF embodiments. Brian has closed several issues on the relational spec. Simon, Amy and Susan to report back at the next telcon on the issues on the present specs. ---
