The OGSA Data Architecture working group will hold a face to face meeting at the National e-Science Centre in Edinburgh the afternoon of August 28 and all day August 29 and August 30. The meeting will be a working meeting focused entirely on driving interface descriptions into the architecture specification and then working the scenario descriptions to be consistent with, and taking advantage of, these interface descriptions. I expect the meeting to be a mixture of group and breakout sessions. A detailed agenda to be agreed to on an upcoming working group call. If there is interest, we may be able to arrange a phone bridge for the group sessions. If you plan to come to the face to face, or are interested in a phone bridge, please let Dave Berry (daveb@nesc.ac.uk) and I (luniew@us.ibm.com) know so that we make suitable plans. Thanks. Allen Luniewski co-chair, OGSA Data Architecture Working Group
