Brooks Dobbs Jeff Edelen Giles Hogben Lorrie Cranor Jack Humphrey Rigo Wenning Dave Stampley Lorrie asked about objections to points a-d. a. http://lists.w3.org/Archives/Public/public-p3p-spec/2004Apr/0001.html http://www.w3.org/Bugs/Public/show_bug.cgi?id=652 b. http://lists.w3.org/Archives/Public/public-p3p-spec/2004Apr/0002.html http://www.w3.org/Bugs/Public/show_bug.cgi?id=653 c. http://lists.w3.org/Archives/Public/public-p3p-spec/2004Apr/0003.html http://www.w3.org/Bugs/Public/show_bug.cgi?id=174 d. http://lists.w3.org/Archives/Public/public-p3p-spec/2004Apr/0004.html http://www.w3.org/Bugs/Public/show_bug.cgi?id=654 There was consensus to adopt a-d. Giles asked about primary puroposes. Lorrie said that this was a separate issue. 2. primary purpose specification http://lists.w3.org/Archives/Public/public-p3p-spec/2004Mar/0035.html [Dave please send revised draft] There was no new Draft. 3. P3P Generic attribute for XML applications http://lists.w3.org/Archives/Public/public-p3p-spec/2004Feb/0019.html http://lists.w3.org/Archives/Public/public-p3p-spec/2004Mar/0003.html Rigo explained that the problem was how to use P3P in new protocols and services. Liberty Alliance and Web Services were not the only applications. Liberty Alliance has not done much but Web Services has recently gotten very interested. Joseph and Patrick's draft had a way to link P3P policies to WSDL via HTTP requests and URIs, but doesn't work offline or without HTTP. Also to describe a complicated WSDL interface requires writing a complicated P3P policy. But there are simple things going on at each part of the interface, so we would really like to address one P3P policy for a part of a WSDL interface. This would also solve the XForms problem of having a P3P policy per field. So... Rigo, Patrick, Steve Pemberton, Hugo, and Phillipe had several calls and worked on drafting a P3P attribute proposal which is in the first public P3P 1.1 working draft. Then Massimo raised the issue that the P3P attribute doesn't have a defined semantic meeting and it can have a different meaning in different contexts. Lorrie raised similar concerns. Rigo had extensive discussions with Massimo about this. Rigo thinks the concern has to do a lot with chunks of XML being sent over the wire (as in CC/PP), but this is not what he has in mind. WSDL and XForms are interface description languages. The P3P policy would apply to what happens when you use an interface. So then there was the suggestion to limit the generic attribute to interfaces and not allow it to be used when XML is sent over the wire. Massimo says it is a hint to XML schema developers but not a MUST. So the question is, do we want just a hint or do we want to try to do something stronger, at least for WSDL and XForms. We could leave it to those working groups to import P3P into their own specs. Giles asked why HTML is not an interface. Rigo explains that WSDL and XForms are interface descriptions because they are not the instance data - that is your name, address, etc. that gets encoded in XML. HTML is the instance data. Giles argues that HTML is actually similar. Rigo says the P3P attribute makes sense for some elements and not others, even in HTML. We need to define interface descriptons. This is tricky. ACTION: Rigo will see if another group has already done this. ACTION: Lorrie and Rigo will work together to draft a proposal for what to put in P3P 1.1. The working group will still need to discuss whether this should be a MUST, MAY, or SHOULD. Giles says there is a difference between saying "if you give me data I will do x y z" and "I'm giving you my data and I want you to do x y z." P3P does the former. 4. Who should be listed as authors of p3p 1.1? http://www.w3.org/Bugs/Public/show_bug.cgi?id=570 5. Dataschema in XML Schema Giles proposed to get it done for week of 23 April. Action: Put out a new working draft with the things ready so far. Action: Giles forward email to Massimo and Martin Presler-Marshall. 6. Publication of next working draft Besides from the above, the only other open item I see is the schema stuff that Giles is working on. Am I missing anything else? ACTION Rigo: Next Draft for 16 April Next working Draft by May 7 with the remaining issues. 7. Authors Who should be listed as authors of p3p 1.1? http://www.w3.org/Bugs/Public/show_bug.cgi?id=570 Number of people that have contributed sections. Dave Giles Matthias Brooks Jack Everybody should be in contributors. 8. Next call 14 April 2004 Scribe: Rigo
