GFD.107
by Philipp Wieder 01 Jun '07

01 Jun '07

Dear All, as you all know, the WS-Agreement specification is now a GFD, namely GFD.107 (see http://www.ogf.org/documents/GFD.107.pdf) This is definitley a reason to celebrate in Seattle, but also a reason to clean up GridForge a bit (yes, yes, it is a Secretary's job ...). Could the person who owns the the latest MS Word document corresponding to the GFD.107 please send it to me in case there are any editorial changes compared to V50 of the draft (https://forge.gridforum.org/sf/go/doc6091?nav=1) Thanks a lot, Philipp.

Negotiation seems to have the most interest for future work. - A doc. has been started on interop. spec. by Omer. Link can be found in the minutes from OGF. - Actions by various as an outcome of OGF have been sent out by Philipp to the mailing list. - Asit has again expressed interest in micro-spec(s) introducing some common KPI for typical (web) service usage. - We should try harder to get more participation in the calls by publicizing the calls with their agenda more prominently (perhaps including updates to project gridforge page).

[Fwd: [ogsa-wg] Proposed agenda for SLT discussion]
by Jim Pruyne 30 Apr '07

30 Apr '07

I see from this note that OSGA is considering SLA's and agreements. I'll be unable to attend this session as I will be travelling. Is anyone from GRAAP able and interested in attending? --- Jim -------- Original Message -------- Subject: [ogsa-wg] Proposed agenda for SLT discussion Date: Fri, 27 Apr 2007 07:15:16 -0400 From: Andrew Grimshaw <grimshaw(a)virginia.edu> To: 'ogsa-wg' <ogsa-wg(a)ogf.org> Service Level Terms – Monday 4:00-5:30 At the last OGSA F2F we discussed the need to address QoS/SLA’s in OGSA. The first step is to define what is meant, to determine use cases, and therefore requirements. It was noted that just defining terms is difficult and very domain specific and that solving the general problem, for all classes of service, is an open question. We therefore decided to begin with a short session focused on two specific OGSA services: ByteIO and BES. In this session we will introduce the problem, discuss the roles of WS-Agreement and JSDL, and define prototype (strawman) definitions of SLT’s for both services. Proposed Agenda: Agenda bashing Present problem Present examples for ByteIO and BES Discuss role of WS-Agreement and JSDL Next steps and action items -- ogsa-wg mailing list ogsa-wg(a)ogf.org http://www.ogf.org/mailman/listinfo/ogsa-wg

Hi: My name is Toshiyuki Nakata. One of the members of the GRAAP WG. I am hoping (if the GRAAP group mambers agree) that we can try to to describe how WS-Agreement can contribute to OGSA BES etc. So.. If you could give me a 10 minute slot in the session, I can try to point out how WS-Agreement TOGETHER WITH JSDL can can contribute to this area. ANd try to　answer any more problems we have.... Unfortunately, my English bandwidth is somehow limited, so I would need to ask some people to be patient... (Ane help/patience is greatly appreciated..) Best Regards Toshi #Jim. Wolfgang et al,　please comment as necessary.. > Service Level Terms - Monday 4:00-5:30 > > > > At the last OGSA F2F we discussed the need to address QoS/SLA's in OGSA.
