by Jim Pruyne 25 Apr '06

25 Apr '06

Minutes are attached. The next telecon will be held on May 3, at the usual Wed. time. At this time, we intend to survey the state of the document, and determine any steps needed to submit back to GGF. --- Jim Minutes from the April 24, 2006 GRAAP Telecon Attendees --------- Toshi Nakata Jim Pruyne Chris Dabrowski Asit Dan Discussion ---------- - Spreadsheet row 41: We'd like Heiko to respond about whether there's still a need for the ContinuingFaultType, if not, we'd like to delete. - Jim to run the schema as defined in the document through the Axis tool chain to verify the correctness. - Jim to make sure that all of the comments in the comment tracker have appropriate responses. - Spreadsheet row 37: We agreed that even if accept fails, the agreement is still accepted, and the initiator must query to find out the status. It would be up to the responder to use other mechanisms like signing or reliable delivery if they do not want to risk accepting an agreement that comes from an invalid source.

All, As promised, I've dusted down the Usage Scenarios, put new GGF boilerplate text (IPR statement, etc.) in, and submitted the document to the GGF Editor for public review. It will be great to see this document finally published. The document can be found in DOC and PDF (Sorry for the usually long GridForge URLs): https://forge.gridforum.org/projects/graap-wg/document/draft-ggf- graap-usagescenarios-02.doc/en/1 https://forge.gridforum.org/projects/graap-wg/document/draft-ggf- graap-usagescenarios-02.pdf/en/1 The GGF Editor tracker for the document is at: https://forge.gridforum.org/tracker/?aid=1726 Cheers, Jon.

by Jim Pruyne 21 Apr '06

21 Apr '06

I have a conflict, so there's no telecon today. Sorry for the very late, non-reminder. We're looking to have one on Mon. or Tues. of next week. If people could let me know their availability on those days, I'll use that to choose which day to have it. Thanks. --- Jim

Access to "Definition of Advance Reservation" Document
by Michael Parkin 20 Apr '06

20 Apr '06

Hi, I'm trying to access the link for 'the definition of advance reservation' [1] from the GRAAP-WG GridForge project summary. When I try to do so, I get the following error: "DCMN-000073: The requested document Advance-Reservation-Definition- htm resides in a hidden category. Permission denied". Is this definition publicly available, or a configuration error on the website? Thanks, Michael.

minutes from 4/14 telecon
by Jim Pruyne 14 Apr '06

14 Apr '06

They are attached. --- Jim Minutes from the April 7, 2006 GRAAP Telecon Attendees --------- Toshi Nakata Jim Pruyne Heiko Ludwig Wolfgang Ziegler Discussion ---------- - Spreadsheet row 23: Heiko will look into adding some text to clarify that when there are no service terms, there can also be no guarantee terms since the guarantee term must refer to a service term. - We determined that we do not need the pseudo-schema in 7.2 and 7.3 as it is not consistent with the real schema, and is covered in the 9.5.2 section on the service state information. - Spreadsheet row 25: Consensus is that would we don't feel like handling the complication of both parties providing a service in the first spec. - Spreadsheet row 26: We'll use Karl's proposed text in the intro. to the appendix as it does seem to explain our intent. - Spreadsheet row 27: Our intent will be to use string for Name type fields, and NCName for Id type fields. We realize this may cause some difficulty with current, though early, implementations. Heiko to make this change after verifying that it doesn't cause significant difficulty in the case of their implementation. - Spreadsheet row 28: Agreed, we should, and we'll watch for those recommendations. - Spreadsheet row 29: Agreed, changes have been made. - Spreadsheet row 30: We've made both Name and ServiceName indicated as MANDATORY. For Name, we did this because they service description terms are referred to by name in other places. We don't feel like tackling the issue of cross-agreement consistency w.r.t. the service names. - Spreadsheet row 31: We agree that it is redundant, but we like having the clarifying text here rather than requiring the reader to refer back to the partent type. - Spreadsheet row 32: We'll use the Name and Id types we agreed upon in row 27. - Spreadsheet row 33: Agreed, and done. - Spreadsheet row 34: Agreed, and done. - Spreadsheet row 35 & 36: Have already been addressed.

extra telecon on 4/14
by Jim Pruyne 14 Apr '06

14 Apr '06

We will have a telecon. on FRI. morning/evening. Dial-in numbers will be the same. The time in the US will remain the same, but the US has changed to daylight savings time over the weekend. I believe this gives us the times: 9:00AM Central Daylight Time US (UTC-5) which should be: 10:00AM Eastern Daylight Time US 1500 UK 1600 Germany 2300 Japan 2100 Thailand Phone Number: 866-673-8466 in the US. 702-477-6031 for those outside the US.

minutes from 4/12 telecon
by Jim Pruyne 12 Apr '06

12 Apr '06

Are attached. We'll meet again on this Friday for an extra session trying to complete the spec before the next GGF. --- Jim Minutes from the April 7, 2006 GRAAP Telecon Attendees --------- Toshi Nakata Jim Pruyne Asit Dan Wolfgang Ziegler Chris Dabrowski Discussion ---------- - GGF17 sessions are all on May 10th starting in the afternoon (1:45PM), and running into the evening. - Spreadsheet row 17: We do not see the need for the symmetrical discovery of guarantee terms by service as it can be derived. Can you provide us a use case to help us see the need? As for the structure, comment, we agree, though we do provide some structure for alternatives. We do assume that all terms are non-optional, though in the case of guarantee terms business value can make them optional to a certain extent. We do support some higher level language to be used in terms. - Spreadsheet row 18: We consider the agreement state and the service state to be independent. For example, agreement creation does not necessarily mean that the service is created. Thus, it does not seem possible to have a state transition diagram that joins the service state with the agreement state. To do this, we would also need to link the agreement to the service when the service is being accessed, and we have not specified that at this time either. We have added text to make it clear that the service states are only applicable when the agreement is observed. - Spreadsheet row 19: Customer obligations can come from the template, or can be added by the initiator in to the offer, but all of the initiator obligations are in the offer. As for the qualifying conditions, the customer obligations (e.g. request rate) or the non-controllable ones (e.g. time) specify when the guarantee is applicable. ** Meta-comment, there are excellent questions from Shamima, and we should capture these answers in a FAQ sort of document. It can make the work we're doing here to answer these in detail more useful and more visible. - Spreadsheet rows 20 & 21: We need further clarification (a use case?) on this comment as we would hope that this is already addressed in the spec. - Spreadsheet rows 22 part 3, and row 24, and row 35: Should we reference XQueryX at all? The consensus is no. Jim to remove all references to XQuery.
