Agenda ------ - Actions from the previous telcon - Report on spec authors meeting held in Manchester - Status report on parallel activities: - Files - OO databases - CIM/DMTF - OGSA Data Services activities(part of OGSA-WG led by Dave Berry) - Progress report on mapping - Update on OGSA Data Services (owned in DAIS-WG led by Allen Luniewski) - Process and time scales for GGF11 - AoB New Actions: ------------ [Simon] Ensure that DAIS liaises with other GGF WGs in a systematic fashion. Actions Resulting from previous Meeting: ---------------------------------------- [Norman] Inform the data area chairs to inform and discuss on how to proceed with regards to File/OO database access. on-going. Dead Actions ------------ [Thomas & Norman] Interact to come up with a page description to scope out a OO database characterisation. Telcon will happen in mid-April. Will be advertised. [Brian/Neil/Ally] To interact with each other with regards to coming up with a file access BOF for GGF11. Had a telcon with Neil - have produced a draft charter to a limited distribution list to iron bugs. Have got in touch with the data area chair. No deadline for submission at the GGF web site as yet. Goes to the data area chair which then it is sent to the relevant WGs. Dave suggests e-mailing Stacy Bruno to find out about dead lines as well as keeping the Data Area chairs in touch. [Norman] Set up a telcon to discuss a telcon for object database access... establish a time and then publicise for people who are interested. done - been set up for mid-April. ------ Simon: Report on the meeting about last week. Norman produced some notes that Sue distributed today ... go through the main items. Notes are based on the agenda. The document structure - discussed changing the title of the documents to have a WS prefix. Would be interested in hearing people's view as to whether this is a good/bad thing to do. Also proposal to further split the realisations a bit further. Relational would spawn off rowset and we would invent something similar for XML, itemlists. Had a session about properties and terms. Differentiating the properties and terms versus the behaviour of the service. Also Allen's OGSA Data Service does not have a Data Description portType. Data access splits down into the messages that we are going to define and the terms that control the behaviour of those of those services. Discussed the structure of the messages such as describing the language and the type of the results that will be coming back. Talked about the placement of the terms in the base document or the realisation documents. Did not say much about factories explicitly - the OGSA Data Service doc states that given a factory interface we can have a factory slot where you can produce new data. Brian spent some time talking about new data. Brian has done a piece of work to see how the different specs relate which arose from the management point of view. Presented as a set of slides which should be made more available. Talked about mappings - describe things generally and then state how these general concepts may be mapped. Talked about timings. This is not intended to be an exclusive process. The meeting was for people that are interested in writing stuff ... you can join in if you want to. Mario: how do people feel about changing the name to Ws- Savas: seems reasonable Simon: Brian anything else about files? Brian: not really. There are other groups in GGF that are interested in files which we need to contact to make sure that we do not overlap. Have not started soliciting input as yet ... Simon: OO realisation - Thomas? Thomas: did not do anything last week and Norman is away on holiday now. Will talk to Norman next week and st out an agenda for the telcon. Simon: CIM/DMTF ... Norman and Susan wrote the scenarios document ... assume that is carrying on. There are other groups we should interact - Metadata, Information dissemination, transaction BOF ... need to decide who is going to liaise with these people ... we should try to be systematic about talking to these groups ... mario this is worth noting ... Mario: there is also GRAAP ... Simon: yes GRAAP ... they seem to be fairly active in their mailing list at the moment. There is also the OGSA data services. Mario would you care to say something about this? Mario: attended the data services telcon that took place yesterday. Currently considering some straw men proposals, see: https://forge.gridforum.org/docman2/ViewCategory.php?group_id=42&category_id=708 I took down some notes that I can distribute if anyone is interested. Have passed these on to Dave Berry who is leading the effort - not sure what he's going to do with them. Andrew Grimshaw appeared to be of the opinion to consider things without taking into account what is already out there. Proposals pulling in slightly different directions at the moment. Dave Berry has set up a fairly aggressive time scale. They have another telcon in two weeks time. In the meantime they will be looking at the OGSA Data Services use cases document to derive input for their straw men. It's too early to say what the impact on DAIS is going to be. .... Simon: Savas can you say anything on the mapping work? Savas: we have a telcon tomorrow. Each one of us has a section that they are working on ... hoped to have something by this week but that's not going to happen but it will be probably happen next week ... from a suggestion from Mario we are now working on an extended abstract for the AHM 2004 to give a paper there. Simon: should take a slot on one of these calls once we have put the document out... process and time scales for GGF11. Is anyone else intending to contribute to the specifications? So far have me, Mario. Amy, Susan, Brian and Norman ... anyone else? *silence* Take that as a no. I assume that people will be willing to comment though? Savas: absolutely. Simon: is there anything else that we should discuss? ... AOB? *silence* end of meeting (quickest ever :-) ).
