This version: 1. Addresses typographical errors noted in Public Comment feedback from Clive & Krasimira 2. Adds an "Information Service" section per Hiro I also took a look at the opening and closing sections to see if I saw an inconsistency in objective for the document (this was a comment received at OGF 21). I saw none. Mario - the Data Access section has a number of uses of MUST and MAY. These are normative and probably should be changed. Please look at them and see if we can do something as simple as lower casing these without losing value. Dave has the write lock per our last teleconference.

I would just lower the case - can do this if I get the token for a couple of mins ... or Dave if he has time when he's passing throug, Mario +-----------------------------------------------------------------------+ |Mario Antonioletti:EPCC,JCMB,The King's Buildings,Edinburgh EH9 3JZ. | |Tel:0131 650 5141|mario at epcc.ed.ac.uk|http://www.epcc.ed.ac.uk/~mario/ | +-----------------------------------------------------------------------+ From daveb at nesc.ac.uk Fri Nov 9 11:39:44 2007 From: daveb at nesc.ac.uk (Dave Berry) Date: Fri, 9 Nov 2007 17:39:44 -0000 Subject: [OGSA-D-WG] Final public comments addressed Message-ID: <2AC085FCF3E737448BE6E2D11A2709F68F3DD1@crosby.nesc.ed.ac.uk> I've just uploaded a new working draft of the OGSA Data Architecture that addresses the public comments from Jens Jensen. I've also added some more text to the Scope section, to properly set expectations. I believe this means we have addressed all the public comments. Hurrah! We have to update the reference given for the Scenarios document and consider how to reference v1.6 of the OGSA Glossary. I'll ask the OGF editor for advice on these points. Other than that, I think we're done. (Oh, and we have to reply to the artefacts in the public comments tracker, but that's straightforward).

DDS is a very interesting on the fundamental publish/subscribe pattern. It has gone in a different direction, real time, compared to where the Info-D WG in OGF has gone. The current Data Architecture document does not really address publish/subscribe. We know that this is an important area but it was simply out of scope for V1 of the document. I would like to believe that it will be discussed in V2 and your participation in that would be very welcome!
