RE: [ogsa-wg] FINAL CALL: OGSA 1.5 Architecture and Glossary
by Subramaniam, Ravi 14 Jul '06

Hi David, I see what you are saying and I did consider that. The glossary term implied a "many to one" or "one to one" situation - one provider. What I was suggesting is a "one to many" situation which is very likely. So the situation where you have multiple providers accepting to an agreement (which at a higher level may be a single contract between domains) is still a "one to many" situation that the glossary term should cover. Right?

We have looked at this a lot in NextGRID, and even complex contracts (such as an EU project) actually boil down legally to a collection of contracts between two organizations, although they all sign a single document.

14 Jul '06

https://forge.gridforum.org/sf/go/doc13654?nav=1 -- Andreas Savva Fujitsu Laboratories Ltd OGSA Teleconference - 13 July 2006 ================================== * Participants Dave Berry (NeSC) Michel Drescher (Fujitsu) Andrew Grimshaw (UVa) Chris Jordan (SDSC) Hiro Kishimoto (Fujitsu) Andreas Savva (Fujitsu) Ellen Stokes (IBM) Jun Tatemura (Hitachi) Jay Unger (IBM) Pete Ziu (Northorp Grumman) Minutes: Andreas Savva * July 10 minutes approved with no changes * Action items review [Only items with updates are listed below.] - Hiro & Andreas to look into re-arranging the F2F Monday and Tuesday morning sessions. - Reviewed on this call. Closed. - EMS team (Steven, Andreas, Donal) to review data staging scenario (section 5 of https://forge.gridforum.org/sf/go/doc13591?nav=1 ) Bring to people's attention again at the next EMS call. (postpone until June 29) - Donal commented on the list. - The topic will reviewed in the Data session at the next F2F. Closed. * July F2F update Reviewed Hiro's proposed agenda. Accepted it with one minor change: - Swap GFS and Naming sessions -- Naming should come first since Andrew has to leave mid-afternoon Tuesday. 'Official' Dinner: - Some people are leaving as early as Tuesday so the first choice is Monday, with Tuesday in second place. * GGF18 - F2F on Friday 9/15 update - Jay has booked a room in an IBM facility within walking distance from the GGF18 hotel (5 blocks). - It is a secure facility and attendees names have to given at least 48 hours in advance. - The room can hold 22 people and has a network connection. - Agreed to pick the IBM facility due to its location -- close to the hotel. (Northorp Grumman location would have required a tube ride). * CDDLM update - Jun will review and correct Hiro's CDL by the F2F session - The post deployment CDL can be retrieved by invoking an operation on 'system' (query using xpath). - Jun will provide the name of the operation and a simple example document showing executable, environment variables. - Hiro will make some minor changes to the sequences to incorporate the above data by the Thursday review. * Basic Security Profile PC review - postponed

Hi Jem/Andreas, A quick comment: In the glossary#Agreement why is the object of the relationship the delivery of a service by *only one* of the parties? Couldn't it be "one or more" since there can be alternates for the same service, multipart agreements or aggregated services? It is possible that GRAAP choose the single party to simplify the management of agreements but this case is a subset of what the term can represent. Agree? Thanks!

The Glossary has the following definition of "endpoint": "Endpoint: A Web Service endpoint to which a client may bind in order to consume a service." So an endpoint is an endpoint. Hmm. Actually, there is a reference to the detailed definition given by the W3C so this entry isn't as circular as it first seems. I still think the phrasing could be improved. Also, to be really petty, the W3C term is "end point" (with a space). How about: "Endpoint: A specific location to which a client may bind in order to access a Web Service, using a specific protocol and data format." Dave. P.S. I should add that I find the Glossary to be a very helpful document. -----Original Message----- From: owner-ogsa-wg(a)ggf.org [mailto:owner-ogsa-wg@ggf.org] On Behalf Of Andreas Savva Sent: 12 July 2006 04:49 To: 'ogsa-wg' Subject: [ogsa-wg] FINAL CALL: OGSA 1.5 Architecture and Glossary Final drafts of the OGSA 1.5 documents ([Arch] and [Glossary]) are available on Gridforge.

Dear OGSA WG, The current drafts of the OGSA Data Architecture and OGSA Data Services documents can be found at https://forge.gridforum.org/sf/go/doc13635?nav=1 and https://forge.gridforum.org/sf/go/doc13605?nav=1. We will discuss these during the Data session of next week's F2F meeting, on Monday morning.

Thanks Donal. A couple of comments: > I think that what would be far more useful would be to merge > this with some of the EMS scenarios to form a combined OGSA > Parameter Space Exploration use-case. But that's a lot of > work to do since it looks like the compute and the data people > are failing to see eye-to-eye (again). If we are failing to see eye-to-eye, that's an argument for making this use case (and other similar ones) a high priority for both compute and data people. I hope we can address some of these issues on Monday. > I believe that some of the things I've been thinking about for the > EPS spec are likely to be useful in the selection of Data-related > resources. All that changes really (at the interface level) are the > input request language and the candidate description language. This seems entirely plausible. Our Data Architecture document makes the point that services such as deployment, reservation, scheduling etc. should be generic enough to handle many different types of resources (including computation, data & network). Although I do know of people in the data world who believe that some of the issues are substantially different for computation & data; perhaps it would be sensible to arrange a brainstorming meeting on this topic. > Service instances are chosen (including any deployment) before the > commencement of the scenario. A question they don't address is > whether moving the computation to the data would be better. This is just one scenario; we could develop another where the computation is moved to the data. From our point of view, when the instances are chosen is of little interest, provided the deployment is managed as necessary. > There is a post-processing phase to be applied to the output data > which the scenario does not properly highlight. We'd be happy to correct this. > A more sensible structure might involve some kind of Orchestration > service (e.g. based on workflows) to control the > parameterized input data creation I believe a later version of this scenario does suggest the use of workflows. We'd be happy to work more closely on this. Best wishes, Dave.

Version 7 of the information modeling guidelines
by Fred Maciel 12 Jul '06

12 Jul '06

Hi, Here is a new version (v7) of the modeling guidelines document. I'm hoping to receive comments on it at the F2F (I'll be participating by phone on Monday). Last time this document was scheduled to be reviewed nobody had read it, the document changes in this version reflect the changes in the last two versions. https://forge.gridforum.org/sf/go/doc12798?nav=1 Regards, Fred Maciel Hitachi America R&D
