OGSA Teleconference - October 6 2004 ==================================== * Participants Peter Ziu (Northrop Grumman) Jay Unger (IBM) Jem Treadwell (HP) Latha Srinivasan (HP) Dave Snelling (Fujitsu) Andreas Savva (Fujitsu) Hiro Kishimoto (Fujitsu) Andrew Grimshaw (UVa) Michael Behrens (R2AD, LLC) Minutes: Andreas Savva & Jem Treadwell * F2F meeting schedule - A number of people completed the online survey - Some confusion over what were valid combination choices (e.g, how to say that the Nov. date was not possible.) - Latha's second survey submission is the right one (Hiro to ignore the first one) - Waiting for Ravi's answer since he is one of the key people for this meeting. The refactoring/V2 work is a key topic. - Washington D.C. seems to be a good choice - Andrew might not be able to attend otherwise (teaching commitments) - Convenient to Jay, Dave also. - Jay booked a room for the F2F in IBM's facilities. - Goal: Show a v2 draft at GGF13 - Need to get v2 doc started in this F2F - Second F2F to review V2 in preparation for GGF13 - Agreed that the second F2F should be in February if the first one is December. Otherwise there is not enough time to work on the document. (It is cutting it very close to GGF13 though). * V1 doc update - GFSG: Ready to publish the document once the group finishes its revision - It is possible to respond to comments that require extensive rework that they will be addressed in V2. - Andreas sent to the list an excel sheet summarizing the comments. http://www-unix.gridforum.org/mail_archive/ogsa-wg/2004/10/msg00006.html - Tracker submissions were per author. They were divided up and sorted by section for a total of 80 items. - The group is happy with the number of comments received. Thanks to all who submitted comments and to those who worked to solicit them. - The excel sheet also includes Dave's comments submitted to a different tracker (ggf-editor)and Philipp Wieder's comments sent to Andreas. - Started categorizing the comments (severity); not finished yet. - Agreed that most comments can be dealt with in v1. Some have to be deferred to v2. Reviewed a small number of items mainly focusing on those that seemed more complex. - Entry 6: comment that spec could be shorter deferred to v2 - Entry 58: Interaction between EMS and Security services - Can be thought of as orthogonal - Andrew will add some explanatory text in the relevant section ("interactions"); more detailed work in v2. - Entry 68: The demand/supply pattern as a generalizing approach still needs more work; deferred to v2. - Entry 69: Elaborate 2 RM subsections: Andreas to follow up with Fred. - Entry 74: Difference between self-management and resource management: Defer to v2; Andreas to see if a paragraph or so can be added in v1 relating to this topic. - Entry 77: Remove UML from Information Services: Agreed that even though this is a big change it must be done to keep the entire document at the same level. Andreas to follow up with Bill/Abdeslem. - Entry 80: Fix references: Andreas to do. - Andrew volunteered to start revising the EMS section and holds the pen for that section. Send revised version to Andreas when done. - Further discussion of issues scheduled for next week's call. * Glossary review - Jem sent to the list a document with all comments relating to the Glossary including his review of them. http://www-unix.gridforum.org/mail_archive/ogsa-wg/2004/10/msg00008.html - Started going through comments in order. - Andrew to review and respond to comments from Sven Graupner & Andrea Westerinen re names and related terms. - Also check Andrea's comment against V1 (entry 78) - Andrew to look at WSDM work and send them a copy of the naming document - Mike Behren's comments about choreography and orchestration: Discussion about terms - the differences are subtle and not necessarily universally agreed. We included those terms because we used them in the OGSA document before it was restructured; if they're no longer used it's not necessary for us to define them here - We might want to limit use to more generic terms such as workflow. - Mike B will review and make a recommendation. - Greg Astfalk's comments: Agreement on changes for several of these (see Jem's revised doc). - Failure recovery: Replace 'resource' with 'entity' in revised definition - IPC is a low-level term for movement of bits from one process to another; Jem will change the definition to include TCP as an example. - No change required for SOA: it was agreed that we don't need to describe attributes that are enabled by SOA, and several references are provided for more details. - Jem will revise the Web service definition to highlight services and/or applications as opposed to machines. - Olegario's comments: - It's OK (and normal) to use "See..." where needed. Agreed no change needed. - Jem will check style guides for capitalization of explanations of acronyms and add a reference to the guide if possible. - General agreement with Jem's view that these words should only be capitalized if they are proper names, but Jem will verify. - The proposed additional words will not be added at this rev, but will be considered for v2 - Andreas will check consumer/provider, since Olegario made a related comment for the OGSA document. - Review to continue next week. * GGF12 review - Minutes: - Security minutes still somewhat incomplete; Andreas to follow up with frank/takuya - Otherwise minutes seem ok and can be approved. - Andreas has a pending action to go through the minutes and produce a list of actions for followup in the calls. * Teleconference scheduling - Summer time is nearly over. So next week the group must decide whether to let people in Japan sleep one hour more or people in Europe go to bed one hour early. - EMS call scheduled for next week Monday; Ravi to lead. - Next week also planning UC document review for final submission.
