Nope. I don't think use cases should come from within the working group if they are not endorsed by any external project. That said, all group members (also those "only" on the mailing list) are more than welcome to submit use cases, even if they are simple. DCIfed is in the stage of trying to find focus.

IIRC, the following points are floating around for a while now:

- the original "DGSI" use case (federation of traditional, community-focused Grid environments)
- the "EGI" use case with OCCI + OVF + CDMI (maybe something else here?) + Federated Security
- the "Gary" use case (see other mails)

While DGSI is the most advanced (specs have been written in the project and most problems have been cleared out), it also is the one with the least impact, addressing a very specific problem closely related to research infrastructures. The EGI use case, in turn, is the one moving forward fastest and being very close to what has been done in the last months by Thijs and Andy within OCCI anyway. Alas, I am not aware how much interest comes from Steven and David to really push this forward in DCIfed (they have published an "EGI" document on this already, see https://www.egi.eu/indico/getFile.py/access?resId=0&materialId=1&confId=415). Regarding the "Gary" use case, we can just discuss this on the list.

With respect to Craig's proposal to compile use cases, I fully agree. I'd therefore propose that we collect the "DCIfed internal" use cases (i.e. the ones that have been submitted to the group already or will be submitted in the future), and align them with the ones mentioned by Craig. Taking up Vivek's document management workflow is surely a good idea; we'd still need someone to endorse it in the group, though.

I'd rather use this for reference purposes in any upcoming document.

Agreed. I will schedule a session for the upcoming OGF in Salt Lake City in mid of July. It's co-located with TeraGrid this year, so there should be enough reason to come.

Best,
Alexander

This group also appears in the NIST Cloud Standards Roadmap -- the first complete draft should be available this June.  I can't promise this material would get into the Roadmap, but we need to make the strongest possible, defensible recommendations wrt existing and emerging standards for cloud computing.

If DCIFed wants to compile another set of use cases, I would recommend taking some time to at least review and comment on the other sets that have been compiled.  I agree with the use case requirements that Gary mentions in his earlier email.  I would add, though, that Vivek Kundra has said that _document management_, i.e., document workflow, is the single largest use case for the US gov.  (This is probably true for all governments!) It also seems to me that secure access through mobile devices, i.e., smartphones, is also high on the list.

I remember Alan pointing me to some NIST standards wiki pages with a table of use cases and cloud desiderata -- would be a good starting point to show what the DCIfed integration is supposed to address, if we assume OCCI/OVF/CDMI to be this integration.
