ACTION: Hiro to send Chris J the names of the people that provided Roadmap sections in the past. * June 8 minutes approved with no changes * July F2F updates ACTION: Hiro will upload updated F2F agenda (mainly updates to the attendees list) * Action item review - EMS team to review data staging scenario (section 5 of https://forge.gridforum.org/sf/go/doc13591?nav=1) ... - Add sequence diagrams to the scenarios ... - Andreas will merge draft scenarios and sequence diagrams ... Above three actions to be re-reviewed on the next EMS call. - Jay will contact Platform (Chris Smith) and Condor ... - Darren/Andreas will take the Modeling position ... Above two actions to be re-reviewed on the next Information Modeling call * CDDLM & EMS - Reviewed Hiro's presenation and XML documents. - Jun pointed out that codebase is used incorrectly. It should be used in the BLAST declaration not in the PosixApplication. - Also it is not clear what the meaning of pre-script is. ACTION: Hiro to talk with Chris Smith and clarify meaning of pre-script ACTION: Jun will correct the CDL XML examples written by Hiro. - What should be the granular unit of components? - It may be better to define 'filesystem' or 'database' as separate components since they may be re-usable in other contexts. For example, they might be usable also by a 3-tier application component. - It was agreed that this kind of refinement is needed. But it is not a showstopper for delivering the top level CDL for the EMS sequence scenarios. - For the EMS scenarios the following CDL documents are needed: - Original CDL from the repository; - CDL modified by JM before submission to Deployment service (portal) - CDL after deployment (can be retrieved by JM to refine the JSDL document) [The deltas should be fairly small.] - Some explanation on what the constructs in the CDL document mean would also be useful since not everyone will have read the CDDLM documents. - Also highlighting what information (if any) is expected to taken from the JSDL document and used in CDL (and vice versa) - In the simplest case it is 'hostname' and path to the installed executable. - Andreas volunteered to review these CDL documents before the EMS call to make sure they provide the expected information. - What is filesystem 'normal' and 'temporary'? - These are JSDL terms defining filesystem persistency. They only address the simplest cases. More information (e.g., performance characteristics) may be added in but such information is not standardized by JSDL---though there may be examples in the spec. - Chris J mentioned that there has been some work on a Data Scenario (for GFS) that looks at how to represent a global filesystem (available locally or as a separate resource). It will eventually be included in the Scenarios document that Dave B mentioned on the last call. * New Gridforge issues - The new WG page is different from the old one. Many links that Jem had added in the past are missing. - Andreas talked to Joel and was told that the new page is autogenerated from the live charter. - Jem will look into the possibility of customizing a part of the front page. In any case a WG wiki is available so a lot of the information should be put there. - There is a problem with the trackers. Artifacts with multiple files attached were not migrated correctly. (Only one file per artifact made it through; the rest came as 8 bytes.) - Andreas has submitted the issue on the gridforge feedback (wiki) page. The gridforge admins (Joel and Andre) are looking into it. Feedback wiki url: https://forge.gridforum.org/sf/wiki/do/viewPage/projects.ggf-info/wiki/Gridf... * Roadmap update - Chris J has had a Roadmap Editor call and has sent the minutes out on the list. - A teleconference with Jem and Hiro and the new team should be arranged. ACTION: Hiro to send Chris J the names of the people that provided Roadmap sections in the past.
