Kai R, Manfred ?? and myself from Primelife 12:11:17 ... had some discussions about a standard proposed by ITU-T ... 12:11:20 ... going into a final state ... 12:11:25 ... X.IDMRequirements ... 12:11:29 ... came out of FG IdM ... 12:11:36 ... data flow model, definitional work ... 12:11:41 ... heavy ISO discussion about that ... 12:11:47 ... but ITU-T not too happy about these comments .... 12:11:58 ... argument is that reducing IDM to basically one model of identity flow ... 12:12:06 ... talking about having the IDP talk to the RP directly ... 12:12:11 ... isn't very privacy friendly ... 12:12:18 ... and there are systems out there that take different approaches ... 12:12:31 ... getting some political momentum toward the end of the Kyoto meeting ... 12:12:38 ... relatively harsh liaison statement to ITU-T ... 12:13:03 ... but ITU-T said they couldn't take it into account, since there had been a liaison before ... 12:13:05 marco: what'll happen enxt? 12:13:07 s/enxt/next/ 12:13:18 jans: There will be some more comments; not sure whether they'll be taken into account 12:13:34 .. talked to German rep to ITU-T, not clear whether they'll get it done in time for end of year ... 12:13:42 ... within ISO, there's ongoing work on Identity framework and privacy architecture ... 12:13:44 +??P12 12:13:47 ... this is out there ... 12:14:00 ... ?? 12:14:20 zakim, ??P12 is christina 12:14:20 +christina; got it 12:14:56 jans: Think a liaison statement should have gone out to PLING giving an overview that WG5 is working on, so useful to look at 12:15:07 ... if I think there's anything that's in scope here, I'll keep you updated ... 12:15:14 rigo: Have you sent that liaison statement? 12:15:23 ... I actually think we still have to write the request letter ... 12:15:40 jan: We actually didn't pass anything in this direction 12:15:54 ... probably a good idea to request liaison with formal statement, briefly describing pling ... 12:16:03 ... mistakenly thought it was already established ... 12:16:09 rigo: on my plate 12:16:43 jan: Please do statement before September, that's the next meeting where it could be approved. 12:16:58 marco: Anything else on the first point.

I fear they might also need some specific authorization ... 12:20:52 topic: TPAC 12:20:56 marco: 24/25 October 12:20:59 ... updates on that? 12:21:14 rigo: what we have to do now (and on the next meeting) ... 12:21:24 ... is start thinking about how many people will come, have to get the room and all that .. 12:21:36 ... set up agenda so we can attract other people ... 12:21:49 ... and actually, also set up and encourage people to attend ... 12:21:54 ... location is very nice ... 12:22:01 ... all kinds of good reasons to go there ... 12:22:09 ... would love to get a really interesting agenda together ... 12:22:21 ... talking about issues we're facing in research projects, and how they relate to existing standards ... 12:22:36 ... talk about what Ashok mentioned; WS-Policy enables negotiation, but how do you combine that with sticky policies ... 12:23:03 ... how can we group the industry to generate sufficient intereest ... 12:23:05 ... these kinds of discussions ... 12:23:07 ... what are the challenges we should focus on ... 12:23:15 ... for the moment we can discuss use cases or interesting cases ... 12:23:23 ... have a bunch, but don't get around to putting them into the wiki ... 12:23:42 marco: anything else we should be aware of? 12:23:59 topic: IEEE Policy 2008? 12:24:08 marco: Was anybody here at that meeting? 12:24:40 umh 12:24:46 s/umh/silence/ 12:25:14 topic: extension? 12:25:22 rigo: If we're still on course, extension would be granted 12:25:36 ... had a short charter, so it's expiring on 30 June at this point ... 12:25:57 ... think it makes sense to continue given PrimeLife and PICOS, and interest in WS-POlicy ... 12:26:06 ... would like to have commitments from chair candidates ... 12:26:13 ... Ashok, is Oracle still interested? 12:26:20 s/interested/supporting/ 12:26:30 ashok: I'm still interested in working with you guys 12:26:34 rigo: That's what I mean. 12:26:53 marco: Does anybody else have something new?

12:30:16 janS: it's some people from Germany that have a specific interest in OpenID because they think it's a good protocol ... 12:30:24 ... interest in being involved, pushing it into the market ... 12:30:30 ... join forces to facilitate that approach ... 12:30:35 ... promotion, use cases, ... 12:31:41 marco: impact on policies in the long term; currently, very blurry 12:32:22 jans: some people think OpenID might be interesting for credentials, but it currently seems to have flaws that make it unsuitable for secure credential exchange 12:32:32 ... suspect that MS could include OpenID with their metasystem ... 12:33:03 ... have heard that there are some implementations for Shibboleth, Liberty 2.0 tries to include both ... 12:33:17 jans: talked to caspar about anonymous credential standardization 12:33:29 ... don't think there should be expectations that anything might happen too soon ... 12:33:36 ... ms and ibm might need to sort out somep oints ... 12:33:46 ... there could be interest in fast-tracking a common standard somewhere ... 12:34:14 marco: expect assertions to carry more and more information ... 12:34:24 ... infocard; also, more and more assertions in liberty ... 12:34:33 ... will impact back-en policies ... 12:34:36 ... ws-policy ... 12:34:53 ... use cases where change of credentials occurs within complex interactions ... 12:35:00 ... in context with access control policies, and so on ... 12:35:05 ... could be interesting discussion ... 12:35:16 ... anything else?
