Hi, first of all thank you for the valuable input to the GSA-RG. I will submit my comments with respect to the document asap. Concerning the GSA use case document and the integration of the Catalana use case, I hope to finalise the document within one week from now, which will give us a more consolidated view and will help to finalise our document. Best regards, Philipp. Mathias Dalheimer wrote:
Hi!
(For the people on the OGSA-RSS-Bof mailing list: We had a short discussion on how to start the work on the service description...)

Let me give it a thought on a simple usecase. Hope to come up with at least a very simple one.
Great! You'll find my current comments of the GSA-Usecase document attached. Basically, I extracted the section on how the various schedulers do their work (their internal workflow). Unfortunately, the use cases do not state for all use cases which data is needed, but I think this can be approximated by looking at their internal workflows. I also included a use case for calana currently submitted to the GSA, but not included in their documents so far.
I would like to invite anyone to edit the document directly and send it back to me - I volunteer to synchronize the changes. In addition, I hope to identify some common properties we need to consider. This should be the basis of our interface design (for which Donal made a proposal, I would be happy to reuse it...)
Mathias, are you ever trying to map the usecases that you are looking at onto the OGSA-EMS Architecture? Would it work out?
This is a very interesting question. At the moment, I am rather optimistic that this can be done. The GSA also identified some common functionality in their GSA Requirement document (which is currently under development, but contains some points we might need to consider). It's here: https://forge.gridforum.org/docman2/ViewCategory.php?group_id=133&category_id=884
Basically, all schedulers follow the procedure of collecting potential resources before actually selecting the right resource. This fits nicely in the scheme defined by OGSA-EMS.
Comments welcome, Mathias
