Hi Sergio,
I've been pulled away to work on another project so I haven't been able to actively look at the specifications you guys have been writing. Anyway, I've got some free time now so I was able to look at what you guys have done with the schema. nice to have you back . So my first question is, how you guys are planning to address the requirements (http://forge.ogf.org/sf/wiki/do/viewPage/projects.glue-wg/wiki/GridAustralia... <http://forge.ogf.org/sf/wiki/do/viewPage/projects.glue-wg/wiki/GridAustraliaRequirements>) we've given you in May 2007? I've looked at our requirements and only four of them (stories 1, 2, 3, and 6 in the link above) have been addressed by GLUE 2.0 spec (draft). All of these four requirements have already been addressed by GLUE 1.3. So from what I see, there hasn't really been anything new added to GLUE 2.0 in terms of the requirements we've asked you to add in the new schema.
Isn't the GLUE 2.0 spec already going for public comments after the next OGF? How are you planning to satisfy our requirements? GridAustralia will be very happy to contribute some of its resources just so the current draft can modified to satisfy our schema. I don't think our proposed schema is only GridAustralia specific so what we add into the specification shouldn't be an issue with anyone on this list. I can assure you that we'll consider all of your requirements. We are almost finishing the revision and consolidation of main entities. The computing entities to which your use cases apply have not yet been reviewed for consolidation. We plan to invest most of the time in January/February on them in order to review vs. use cases. OGF 22 is at
Hi Gerson, Gerson Galang ha scritto: the end of February therefore we have enough time, though we cannot relax too much. I hope you'll be able to actively participate in the Jan/Feb telecons. Please, let me know about your time constraints for planning. Cheers, Sergio
I also just want to comment on story 6 of our requirements. We know that you've satisfied that requirement by adding the ModuleName attribute to the ApplicationEnvironment entity but some Grids (e.g. TeraGrid) don't use modules and JP Navarro has suggested a more generic approach (and a better way of representing this type of information) and that's by using HandleType and HandleKey attributes. See below..
<ApplicationEnvironment> <ID>123</ID> <Name>apache-ant</Name> <Version>1.6.5</Version> <HandleType>softenv</HandleType> <!-- this can have a value of modules as well --> <HandleKey>+apache-ant-1.6.5</HandleKey> <!-- when modules is the value of type, the key will be apache-ant/1.6.5 --> </ApplicationEnvironment>
We're happy that you've got ModuleName in there but since this is a schema that will be used by a number of grid middleware/apps around the world, we just want to do it properly and avoid tying this version of the spec to a particular environment loading package implementation like "modules".
It may be that you might not want to implement stories 9, 10, and 11 because you might think that it's just too hard to implement or you just think that there won't be any users/applications going to query for that information. If so, it would be good to get some feedback on the issues with our requirements.
Story 13 is not related to software application so we want to know how you are planning to address that in GLUE 2.0?
We also would like to hear your comments about the things we've listed under the "Glue 1.3 issues/comments" section of the GridAustraliaRequirements. I know those are not only applicable to GLUE 1.3 because I don't see the current draft of GLUE 2.0 addressing those issues yet.
Look forward to hearing from you.
Regards, Gerson

Dear all,
at the following page you can find the minutes of yesterday call: http://forge.ogf.org/sf/wiki/do/viewPage/projects.glue-wg/wiki/PhoneMeeting2... <http://forge.ogf.org/sf/wiki/do/viewPage/projects.glue-wg/wiki/PhoneMeeting20071130>
the new GLUE Spec draft (no.18) is available here: http://forge.ogf.org/sf/docman/do/viewDocument/projects.glue-wg/docman.root.... <http://forge.ogf.org/sf/docman/do/viewDocument/projects.glue-wg/docman.root.drafts/doc14639/18>
the new XML Schema rendering, XML example and updated mapping rules can be reached from this page: http://forge.ogf.org/sf/wiki/do/viewPage/projects.glue-wg/wiki/GLUE2XMLSchem...
during the next week I will be in USA (West Coast) because I'm attending a conference ( http://www.mandevcon.com/) where I will be presenting the work that we (INFN) are doing in the framework of OMII-Europe to implement GLUE 2.0 based on WBEM technologies.
For next calls, I talked to Balazs and seems that the first intersection is in the week 17-21/12. I would propose 18 and 20 Dec as the last calls for this year: http://forge.ogf.org/sf/wiki/do/viewPage/projects.glue-wg/wiki/PhoneMeetings <http://forge.ogf.org/sf/wiki/do/viewPage/projects.glue-wg/wiki/PhoneMeetings>
Please let me know if you can make it.
Meanwhile, we can make progress on the mailing lists. I will send specific e-mails to ask for feedback contributions on open tasks: http://forge.ogf.org/sf/tracker/do/listArtifacts/projects.glue-wg/tracker.gl...
Cheers, Sergio
