That is actually not quite true. BES states are just listed as a set of possible values under the "BES:" namespace. BUT any other set of states can be published in glue2.

Next job management teleconference wednesday may 20th
by Moreno Marzolla 18 May '09

18 May '09

Dear all, the next PGI teleconference will be held on wednesday may 20th at 16:00 CET (duration: 1 hour). Call-in details as follow: via Skype call +9900827049931906 (free of charge) ordinary phone numbers (local rates) with the 9931906 conference number: Austria 0820 401 15470 Belgium 0703 57 134 France 0826 109 071 Germany +49 (0) 180 500 9527 Switzerland 0848 560 397 Agenda (please feel free to suggest additional items): 1) Resolve issues on the "GES Strawman", according to Andrew's comments:http://forge.ogf.org/sf/go/doc15633?nav=1 2) Additional discussion on "GES realization via existing specifications" (version 2 by Andrew has been uploaded to gridforge: http://forge.ogf.org/sf/go/doc15630?nav=1 ) 3) There is the feeling that reaching a consensus on the implementation of the job management interface is proving to be harder than expected. Should we focus our initial effort on defining (in plain English) a high level description for a job execution service based on an agreed set of requirements, so that we come out with a set of operations, input parameters and output data? Defining a suitable rendering of such interface could be the next step.

One question that WILL be asked at the next OGF when we review the groups working on standards is the progress that has been made... Can the chairs please articulate how the work of PGI has moved on and what has been achieved since Catania?

No Security Call Today

Re: [Pgi-wg] PGI Execution Service - Realization viaexistingspecifications

Hi PGI team, in parallel to our technical discussions, I think it would be a great benefit to get statements on the WIKI as mentioned today in the TelCon about pro/contras: >-http://forge.gridforum.org/sf/wiki/do/viewPage/projects.pgi-wg/wiki/GES?_m es >-sage=1242216401105 @Andrew: Clearly the history of the wiki (that I can't change in respond to "hopefully unintentially removed") points to no edits from your side - I gave you now all the permissions possible in GridForge - so if this problem was maybe related to this it should be gone now. If you like to provide your views - please feel free to add, I really think it's worth adding them to acknowledge different view points that might lead to a wise decision in this context.

Morris, I was asked to prepare a document on how existing specs - with small modifications - could be used to implement the requirements in the GES document.

Morris and All, Concerning the PGI Execution Service : Lot of thanks to Morris for the wiki page at http://forge.gridforum.org/sf/wiki/do/viewPage/projects.pgi-wg/wiki/GES I am NOT especially Pro or Contra : - keeping the existing stacked specifications, - or starting a new stand-alone focused specification. But we need clarification, and I think that this wiki page helps. So I added into this wiki page the 'List of OGSA-BES et al. specifications'. Please verify if this list is complete, relevant and accurate.

Move together as a team step by step
by Morris Riedel 13 May '09

13 May '09

Hi PGI team, I'm looking forward to the upcoming telcon hoping that we can work together as a great team to achieve good results. I remember that my "step by step" approach was (to the best of my knowledge) commonly agreed in the last telcon, therefore I suggest to focus first today purely on the create operation and its side-effects only in a limited manner. To support this process of mutual understanding I provided a factsheet on GridForge addressing both documents related to possible renderings only focusing on this particular operation: http://forge.gridforum.org/sf/docman/do/downloadDocument/projects.pgi-wg/doc man.root.input_documents.execution_service/doc15631 I use it to understand the different views and to check if we have considered everything. Please feel free to comment and Moreno feel free to take it as a discussion outline today for the Telcon today about the different documents.
