The repost didn't make it even a second time. I think... ---------- Forwarded message ---------- Subject: Ad-hoc BOF on Streams at GGF15 Date: Fri, 23 Sep 2005 14:16:29 +0100 From: "Dave Berry" <daveb@nesc.ac.uk> To: <saga-rg@ggf.org> Cc: "Allen Luniewski" <luniew@almaden.ibm.com> Dear SAGA RG, We are organising an ad-hoc BOF at GGF15 on the subject of data streams in Grid architectures. Our aim is to bring together people working on various aspects of data streams. Our personal goals are to determine how best to fit streams into the OGSA Data architecture but we also see this session as an opportunity for people to share experiences and meet others working in overlapping areas. We hope that some of you will come along and contribute to the discussion. In particular, we would welcome a speaker from the SAGA RG. Please contact me if you would like to speak. The BOF will be from 6.00-7.30pm on Monday Oct. 3rd. The first half of the session will see presenters addressing some of the questions below. We will keep the second half of the session for discussion. Issues to consider: - What do we mean by a "data stream"? - Grids have to consider attributes such as security, persistence, and quality of service. Do these raise any particular questions for streams? - What are the important use cases? Are there unusual or non-obvious cases that we need to consider? - What is the natural programming model for streams in a distributed environment? - How do we connect one stream to another? - How do streams fit into a service-oriented architecture? - The OGSA Data Architecture currently has sections on Provisioning, Querying, Replication, Caching, etc. Do these apply to streams as well as static data? Are there any particular aspects of streams that affect any of these sections? We look forward to seeing you there.
