OGSA Teleconference - 14 July 2004 ================================== * Participants Bill Horn (IBM) Hiro Kishimoto (Fujitsu) Fred Maciel (Hitachi) Andreas Savva (Fujitsu) Frank Siebenlist (ANL) Latha Srinivasan (HP) Jem Treadwell (HP) Jeffrin Von Reich (HP) Minutes: Andreas Savva * Resource Model discussion Discussed the applicability of CIM to OGSA. A number of questions or doubts were raised: - Does CIM have sufficient meta-capabilities? - It does include a meta-model. - It was suggested that it is easier to handle multiple models rather than multiple renderings.(?) - Is this the only way to achieve interoperability? Is it possible to avoid choosing a specific model and do mappings at a higher level instead? - How well adopted is CIM? - There is some adoption on the systems side but not so much on the network side. And very little on the applications side. - (Jeffrin) seems more interested in mapping between models rather than assuming there is a single model. - Looking at relationships and being model-agnostic seems to be what WSDM is doing. A first candidate within OGSA to use CIM is EMS. But Fred is worried that we are talking about EMS as an example for resource modeling when there are no EMS people on this call. - Also it is not clear that OGSA has progressed enough to the point of being able to feed in requirements to CIM - CIM is complex and it is not always clear how or where to extend the model - Next step: Hiro to try to get more EMS people to join the next call - EMS Container & Job as two initial modeling topics * Use case document public comments review - Process discussion: Discuss within group first, reach consensus and then post replies to public comment tracker 1. "Service utilization" - 'platform service': This is no longer consistent with the current OGSA document. Perhaps the term should be changed; but in any case it does not sound like a major problem. - Perhaps add some explanation on what the template should be describing. Action: Relevant people (OGSA-WG) should review document and come up with a proposal on how to handle this issue. 2. "Advance" vs "Advanced" reservation Discussed whether 'advanced' actually means something else (e.g., complex reservation) Action: Jeffrin will review document and kick off discussion on whether the two terms mean different things. 2-1. Disagree with suggestion to list requirements for general workflow engines 2-2. Time to process reservation: Hiro agreed that wording is not very good and should be changed. Action: Jeffrin to edit and Hiro to check 3. Agreed to change 'enterpise' to 'organization' though there should not be a problem either way. 4. This is a term defined by this use case. No extra explanation is needed. 5. Abstract: Agreed to re-phrase. Jeffrin to do. 6. Agreed to - Fix figure captions to make consistent - Bibliography per section is ok, but fix inconsistent formatting - Section refs are incorrect: Search for 'section' keyword and make into real cross refs to the section numbers 7. English corrections: ok. 8. 7.2.2 service description: - The comment is not clear; ask for more explanation. - Workflow as GS: Not sure if this has to be drawn out in this case but adding a reference is a possibility. Need more information about 'taverna' and what they think its relevance is. - Collaboration: Reject. It seems inappropriate to add implementations. - Machine readability: Agree in principle but not sure what need to be added. - Collaboration: Add a sentence about 'dynamic nature' and 'description language' - Other comments: - Jeffrin to check again who is the original author of the mutual authorization use case and add to contributors - Acknowledgment: Should 'work supported by' be kept? - Confirm with relevant people first(e.g., Ian Foster) - Should refactor the use case document to make it consistent with the OGSA doc. But it is not clear how much work this will be.
