Dan: We may need a W3C focus ... maybe a get together 18:16:39 q? 18:17:24 Noah: Difference between expectations and contents which 18:17:27 action-507? 18:17:27 ACTION-507 -- Daniel Appelquist to with Noah to suggest next steps for TAG on privacy -- due 2011-01-03 -- OPEN 18:17:27 http://www.w3.org/2001/tag/group/track/actions/507 18:17:35 Tim mentioned something about detecting someone's TCP/IP stack by observing the timing of their packets 18:17:47 ... we have action 507 which is to suggest next steps about privacy 18:18:09 NM: re ACTION-507, next steps for TAG, what should we do? 18:18:09 Dan: Minimization is important .... but it is a micro issue 18:18:19 Tim said something about whether trying to solve the problem at the application layer by cutting off identifying information doesn't address the problem 18:18:31 ... buiding block but does not solve user privacy 18:18:32 DanA: one bit of my answer on 507 is the minimization stuff, but that's a pretty narrow slice of the privacy pie 18:18:42 "the whole fingerprinting issue" I think this is key 18:19:10 ... fingerprinting issue is important ... should be in context of new initiative in W3C about privacy 18:19:28 s/be/be discussed/ 18:19:29 q+ to discuss whether TAG could summarize a W3C view of "what is Privacy" and "why is it hard?" to start with 18:21:00 q+ to mention p3p 18:21:06 q- 18:21:12 Tim said what I was going to say 18:21:23 ack next 18:21:24 Larry, you wanted to discuss whether TAG could summarize a W3C view of "what is Privacy" and "why is it hard?" to start with 18:22:21 Larry: Workshop focused on solutions ... there may be a initiave but could we summarize "what is Privacy" and "why is it hard?" 18:22:37 ... this may be something the TAG should do 18:22:43 sometimes when there's a hard problem, just framing the problem can be valuable 18:22:56 -TimBL 18:23:09 Dan: Valuable to write up what we think the issues are 18:23:22 perhaps we could have an opinion about which things are in scope for W3C and which aren't? 18:23:38 we're not going to attack packet timing, are we? 18:23:49 we definitely need to check with tlr 18:24:05 q? 18:24:05 Also check with Phillipe 18:24:48 q? 18:24:56 Noah: We should try and define the issues related to privacy 18:25:07 +TimBL 18:25:11 Action items: http://lists.w3.org/Archives/Public/www-tag/2010Dec/att-0061/ActionItems_Workshop.pdf 18:25:11 Sorry, couldn't find user - items 18:26:01 IETF Actions 18:26:01 • Create privacy directorate 18:26:01 • Investigate possible research work in privacy (IRTF) 18:26:01 • Explore what the IETF can learn from Tor (and vice 18:26:01 versa) 18:26:02 • Support for continuing “Privacy Considerations” work 18:26:04 – Apply it to some IETF protocols 18:26:06 – Covers HTTP/non-HTTP-based Protocols 18:26:09 • Fingerprinting Considerations for IETF protocols (TCP, 18:26:10 HTTP, SIP, etc.) 18:26:15 Noah: If you go to Slide 3 you will see IETF actions ... slide 4 is W3C actions 18:26:16 W3C Actions 18:26:16 • Formation of W3C Privacy Interest Group 18:26:16 • Fingerprinting of W3C protocols 18:26:18 – How to help 18:26:20 • API Minimalization 18:26:22 • Referrer header & privacy 18:26:24 • Privacy Considerations for Non-Browser-based 18:26:26 Protocols 18:26:26 DKA has joined #tagmem 18:26:28 • Usability: 18:26:30 – Whitepapers &BCPs (?) 18:26:32 – Usability Considerations in W3C specifications 18:28:13 Dan : There was heavy IETF participation ... they wanted privacy considerations and privacy review for each spec 18:28:30 Following on Larry's thought, if you require a "privacy considerations" section, then it needs to be at least somewhat clear what's in scope under the term "privacy" 18:28:57 ... similar to security review 18:29:15 Dan: Debate abt do not track mechanism ... this is important 18:30:30 Yves: Problem with jurisdictions 18:31:40 q? 18:31:48 Dan: Our privacy lawyer said that the EU would be looking closely at the Do Not Track and would probably follow the US lead 18:32:02 ... the Canadian person said the same thing 18:32:55 q+ 18:33:14 http://donottrack.us/ 18:34:08 Dan: The Berkeley folks recommend a Do No Track header and this had some traction 18:35:36 Noah discusses use of Google Analytics on his blog 18:37:06 donottrack.us seems sort of short on analysis and detail. would be nice to know more 18:37:47 Larry: Why don't we discuss the action items? 18:38:15 Noah: First is to start a Privacy IG 18:38:43 AM: There is currently a policy languages IG 18:39:07 AM: Ends next month.

However, in some cases microdata is not URis but just "terms" 19:08:04 Examples: http://dev.w3.org/html5/md/#examples 19:08:24 http://www.w3.org/1999/xhtml/microdata#http://microformats.org/profile/hcard%23: 19:08:24 rdf:type ; 19:08:24 "Princeton" . 19:08:30 First example shows full URI 19:09:09 Second example mints a URI by ... ... 19:10:06 q+ to query the seriousness of this proposal [off the record] 19:10:26 TBL: Seems to be an attempt to use http uris (so far so good) with an effort to put fundamental control with HTML WG, then also the microdata folks, then (...didn't catch the rest...) 19:10:58 TBL: Might make a bit more sense if the 2nd URI were % encoded. 19:11:19 TBL: Seems to let W3C publish schemas for stuff that comes from microdata folks. 19:11:52 TBL: Alternative is to just ask microdata folks to publish schemas directly, or that failing, put some on the side ourselves. 19:12:01 ack ht 19:12:01 ht, you wanted to query the seriousness of this proposal [off the record] 19:12:37 HT: Is this a serious proposal? 19:13:18 ... we need someone who cares about RDF to confirm that this is serious 19:14:21 Larry: This is a problem with namespaces in RDF 19:14:58 The alternative to prefixes is full URIs throughout 19:15:36 Where is HTML5 on entity declaration -- not available to users, right? 19:16:08 Noah: So, this would require prefizes in HTML ... may be a tough battle to fight for this case 19:17:13 ... HTML5 folks would consider this a corner case 19:18:08 I think Larry's point is actually relevant input into HTML Issue-41 (decentralized extensibility) 19:18:25 Larry: Tere is a significant community that does not see metadata as useful 19:18:32 s/Tere/There/ 19:20:31 HT: If HTML5 folks adopt a prefix binding this would simplify this part of their spec also 19:21:06 Noah: Is there serious proposal along these lines for issue 41? 19:21:20 ... I don't think so. 19:22:13 HT: There is a mechanism for prefing but I think it is only for attributes 19:22:20 NM: I thought that the only options currently open for their issue-41 were do nothing, and trigger on well known root elements (a la ) 19:22:21 "We thus require that a prefix always map to the same namespace, and that this mapping be registered." 19:23:24 Tim: We should push back 19:23:33 q? 19:23:45 Noah: Can someone draft a note that we could discuss 19:24:14 Actually, what I said was: can we get sufficiently close to agreement on what the TAG's key messages would be that we could ask someone to draft those points. 19:24:36 TBL: Normally, the person who has ownership of the URI should be the same as the one in a position to publish and maintain the ontology 19:24:39 q+ 19:24:53 Tim: The way that RDF works is that someone who creates a terminology publishes an ontology about it 19:25:08 Wrt the extensibility proposal (http://www.w3.org/html/wg/wiki/ChangeProposals/extensionslikesvg) it _does_ appear that xmlns:xxx=... is allowed 19:26:20 ack next 19:27:25 jar: Any don't think anyone will listen unless there is an alternative ... "we don't like this" will not do much 19:27:45 ... ask why URI has to have that form 19:28:10 ... they may have reasons why they do it that way 19:28:34 zakim, pick a victim 19:28:34 Not knowing who is chairing or who scribed recently, I propose John_Kemp 19:30:14 still trying to understand step 6... I don't understand where 'type' comes from... 19:30:25 If item has an item type and that item type is an absolute URL, let type be that item type. 19:30:34 ahh.... meaning of attribute names is scoped to item types... so what is an item type... 19:31:09 so the question is, what problem is this unpleasant solution attempting to address? and is there a better alternative? 19:32:04 ACTION: Tim to write a note conveying the TAG's concerns re: the microdata -> RDF URI mappings in the HTML5 microdata draft Due: 2011-01-20 19:32:04 Created ACTION-510 - Write a note conveying the TAG's concerns re: the microdata -> RDF URI mappings in the HTML5 microdata draft Due: 2011-01-20 [on Tim Berners-Lee - due 2011-01-13]. 19:32:06 the URI apparently needs to combine the type URI and the attribute name, which might have a : in it 19:32:43 wondering what examples of type URIs are - can the property URI be built with the type URI as a prefix? 19:33:02 -ht 19:33:15 rrsagent, make logs public 19:33:16 timbl, i have entered my notes in case they might be of help to you. 19:33:18 Have to give regrets for next week. 19:33:37 rrsagent, pointer 19:33:37 See http://www.w3.org/2011/01/06-tagmem-irc#T19-33-37 19:33:59 -DKA 19:34:01 -Noah_Mendelsohn 19:34:03 -Yves 19:34:04 I am going to ship new versions of mime-web-info and dated-uri 19:34:04 -Jonathan_Rees 19:34:04 -John_Kemp 19:34:06 -plinss 19:34:13 -TimBL 19:34:16 apologies in advance if i missed your comments, please remind me 19:34:20 -Masinter 19:34:32 -Ashok_Malhotra 19:34:33 TAG_Weekly()1:00PM has ended 19:34:34 Attendees were DKA, Ashok_Malhotra, plinss, Jonathan_Rees, Noah_Mendelsohn, Masinter, John_Kemp, Yves, [IPcaller], ht, TimBL 20:14:04 timbl__ has joined #tagmem 21:31:42 timbl has joined #tagmem 22:00:44 Zakim has left #tagmem 22:09:37 Norm has joined #tagmem 22:16:18 Larry has joined #tagmem 23:38:05 Norm has joined #tagmem
