<scribe> Scribe: Dan
trackbot, start meeting
<trackbot> Date: 28 April 2011
Noah: Any regrets for next week considering the AC meeting?
<ht> HT regrets for 18 May
Ashok: I can scribe next week.
Noah: move to approve.
Resolution: Minutes from last call approved.
Noah: are you at the Privacy workshop, Ashok?
Ashok: yes. It's just started. Let's discuss next week.
Noah: Any priorities?
... AC meeting in Bilbao. Who will be there?
DKA: yes I will be there. I will be chairing a panel on mobile stuff.
Noah: 5+ weeks until f2f.
<jar_> issue 57
Noah: What are themes and priorities? Major topics they'd like to discuss at f2f? And/or commitments for writing?
<noah> Jar, are you suggesting issue-57 for F2F?
<noah> Hi Tim.
Ashok: I would like the client side state work talked about. I will write up something about client side storage.
JAR: I'm working hard to get a document ready [on issue 57] and we should be able to discuss at f2f.
Noah: How about the copyright and deep linking stuff?
DKA: I'd like to "go to last call" on some of these.
Noah: on copyright and deep linking - we had a broader discussion. Then we agreed to work on terminology. But what is success here? Should that just be the terminology? Or is that just a first puzzle piece?
JAR: latest draft has gone beyond terminology.
<noah> Feb F2F http://www.w3.org/2001/tag/2011/02/08-agenda
Noah: Let's try to use email and
teleconferences to focus that over the next two weeks.
... HTML / XML? We could ask Norm to join us?
<ht> +1 to revisiting XML/HTML
<noah> ACTION: Noah to ask Norm about HTML/XML at June F2F [recorded in http://www.w3.org/2011/04/28-tagmem-minutes.html#action01]
<trackbot> Created ACTION-548 - Ask Norm about HTML/XML at June F2F [on Noah Mendelsohn - due 2011-05-05].
<trackbot> ACTION-546 -- Noah Mendelsohn to ask Jim Gettys about joining us for lunch at June F2F Due 2011-05-15 -- due 2011-05-17 -- OPEN
Noah: I have action-546 which was
to get in touch with jim gettys.
... roughly: the issue is about the way people are building network devices and software to use the lower layer of the TCP/IP stack. TCP depends on flow control.
... in a network with a bunch of links - one of the hops might be slower which can cause things to back up. The way TCP handles this is that it depends on packets starting to drop.
... TCP notices this and slows down. Problem that Jim has identified is that people are building network devices and browsers that are buffering too much or generating too much traffic and that can cause failure.
... he can give the details. Relevance to the tag is questionable. Decision is to invite Jim to lunch on Monday the 6th.
... Jim did feel that some of this is attributable to a misuse of http by user agents. [this could be architectural]
<trackbot> ACTION-546 -- Noah Mendelsohn to ask Jim Gettys about joining us for lunch at June F2F Due 2011-05-15 -- due 2011-05-17 -- OPEN
Noah: Jonathan - anything on metadata other than issue-57?
JAR: Larry and I will get together at end of May to work on it.
Noah: persistence of references?
JAR: I'd like to make a decision on that a little later. Nothing new right now.
Noah: Registries - we'll have to
... Security and webapp things.
DKA: Webapps APIs minimization. Also interaction models if I can engage with the webapps working group members.
Noah: Also security and privacy - privacy we should visit next week post [workshop]. Security also very important. Any comments?
JAR: I don't remember how we left John Kemp's draft but we should do something with it.
<Ashok> +1 to JAR suggestion
<jar_> wish I had time.
<noah> <noah> PROPOSAL: close ACTION-417, and have John publish what he's got, slightly cleaned up, as a note with no formal status, but at a stable URI. Noah will help.
<noah> <noah> Larry will help too, and would like this done in time for IETF in Prague.
<trackbot> ACTION-515 -- Larry Masinter to (as trackbot proxy for John) who will publish http://www.w3.org/2001/tag/2011/02/security-web.html, slightly cleaned up, with help from Noah and Larry -- due 2011-04-12 -- OPEN
<trackbot> ACTION-516 -- Noah Mendelsohn to talk with Thomas Roessler about organizing W3C architecture work on security -- due 2011-04-26 -- OPEN
DKA: Should we talk about #!?
<Yves> part of client-side state indeed
Noah: Yes as part of client side state.
Noah: History goes back 2008. TAG
met with HTML working group in Mandelieu. Concern that the
HTML5 spec was a user agent specification, not a language
... TAG agreed that it would be fine if HTML group continued with the authoring view - [a "view" into the full spec for document authors]
... "HTML5 Edition for Web Authors"
<noah> HTML5 Edition for Web Authors
<trackbot> ACTION-379 -- Noah Mendelsohn to check whether HTML language reference has been published -- due 2011-04-26 -- PENDINGREVIEW
Noah: we agreed it would be fine
if it was taken forward on Rec track.
... reporting back on action-379. I am satisfied that it is happening.
... this will be carried forward as a rec track document. I would like to close action-379 and move on.
<noah> closing ACTION-379
+1 to that it's a big deal and +1 to closing the action
Noah: Good news.
<trackbot> ISSUE-60 -- Web Application State Management -- open
<JeniT> I have
<jar_> I have mostly
<JeniT> Looked good to me
Noah: I'm pleased.
I read it but not at a detailed level.
Noah: [I think we should change the title.]
Ashok: Yes. We have a different message now.
<jar_> liked "you have a control you can move out of the page."
Noah: You have a reference to Jenni's blog. Is that an appropriate long-term reference.
[I think it's appropriate considering the source]
<JeniT> You're welcome to copy relevant text
Ashok: I can take her arguments and summarise them.
<Yves> ok if it's an informative ref (which it is)
DKA: Could mirror it in TAG space...
Noah: We could keep it as a blog reference or paraphrase it in the document.
<jar_> this one, right? http://www.jenitennison.com/blog/node/154
<JeniT> yes, that one
Tim: I think it's good for the TAG to keep stuff in W3C space for persistence.
<jar_> email it to www-archive
<ht> So we change that sentence to a standard reference, and the reference at the end uses a TAG URI and says it's a copy of Jeni's blog, with a URI for that too.
Noah: We haven't often reference in a TAG finding things like this...
<noah> DKA: Jeni could repost on TAG blog
<noah> NM: Sounds good to me
DKA: Another option: Jenni re-publishes her entry on the TAG blog.
<Zakim> ht, you wanted to say yes
<JeniT> I'm absolutely fine with that, whatever makes it easiest to use
Henry: want to agree with Tim - either put a copy in tag space or do what Dan said.
<Yves> TAG blog entry seems appealing
Jeni: I'm happy doing anything that's useful. Putting it into the TAG blog seems most appropriate. Copying parts of it into the document itself might be better, if appropriate.
<noah> I have no problem linking >both< the original Jeni blog, to give credit where it's due, and a W3C blog copy, advertised as stable.
Ashok: level of detail between the two are different. I'd rather link to a stable document.
Noah: Last thing - section on
... 3 bullets [reads doc]
Noah: First bullet - any
... second bullet - any comments? this is effectively saying "google maps is broken"...
[some discussion on what google maps does]
<timbl> Noah: Google maps does the right thing with forward and back
Jeni: I think it is a bit strong. I think it's going to be up to the developer to determine what's appropriate for their application. I think it would be strong if it said must but Ok to say "should".
<Zakim> timbl, you wanted to ask whether there is a good reason for that behavior that they don't change the URI at every move
<Zakim> noah, you wanted to answer Tim
Tim: Google maps and open street map have this behavior that they change your history but don't give you a snapshot in the address bar. There are reasons and the TAG document should discuss them. Possibly it's distracting? Possibly it's because of leftover issues with [older] browsers?
<noah> TBL: Why are they not doing it now that they can?
<noah> NM: Good question.
Tim: Why now, when google maps code is updated regularly, does it not [use the API] to change what's in the URL bar?
Noah: It would leave them in a position where they need 2 user interfaces...?
Tim: But they do that already -
<JeniT> I suspect it's because the URIs are too complicated to generally expose to people
Noah: we have a recommendation for one way and google does it another way - we should understand why they do it that way.
Ashok: I can ask Raman [ who could talk to us about it ]?
<noah> I think the question Tim asks is: "Now that more and more browsers support the new history API, why does Google Maps still not update the address bar on those browsers?"
Noah: back to the "best
practices" - third bullet.
... it has advantages / disadvantages for #! ...
<JeniT> Ashok does say "So far, this works only for Googlebots and no one seems to like it."
Noah: should it make more explicit recommendation?
Ashok: We can tinker with the wording...
<JeniT> I don't think it's ok
DKA: I think we should recommend against it... or at least come down slightly in that side.
<noah> I guess what I'm saying is: using the # leads you to messes like #! and kludges like the Google query stuff. It also seems to violate specifications.
Jeni: I think we need to strongly encourage people away from using # and #!. But not too strong.
<JeniT> I said that in the short/medium term it's impractical for people not to use #/#!
<noah> I heard Jeni say that, in the short term, # may be the only practical option for some, and we should acknowledge that
<noah> When something has real architectural problems, I prefer that the TAG goes beyond just saying: well, there are pros and cons.
<Yves> presenting pros and cons and let people decide based on their needs is better than say "no"
Ashok: It's a matter of style. What I've tended to do is to say "if you use x, these are the benefits and these are the difficulties." I am a bit reluctant to stand up and say "&^£*&^@£ don't you do this." We should sumamrize the arguments on both sides and stop there.
<Zakim> noah, you wanted to talk about style
Ashok: Jonathan what you typed could be a reasonable thing to add.
Noah: People look to us for architectural guidance. When we think something is going to undermine the architectural integrity of the Web then we should say that. And I think this is one of those cases.
Noah: I think it's appropriate for the TAG to be a little more than dispassionate. The Web is a system that connects people. If people violate the specs then it gets fragile.
<JeniT> +1 *or* we change the normative specs :)
Noah: if we agree that the world
would be better then it's appropriate.
... Thank you, Ashok. Very significant progress.
<jar_> ashok, I think it's going well
<trackbot> ACTION-481 -- Ashok Malhotra to update client-side state document with help from Raman -- due 2011-04-12 -- OPEN
<noah> ACTION-481 Due 2011-05-10
<trackbot> ACTION-481 Update client-side state document with help from Raman due date now 2011-05-10
[discussion on where to put it - tag/doc]
Noah: I would encourage you to move it to /doc earlier rather than later. Then every time you want to discuss it spin off a dated copy in /doc
Tim: We talked about the
high-level goals. Could we pick some things against which we're
prepared to be measured. One of them was reviewing HTML5.
... We talked about metatdata in general.
Noah: We need to report to
... we could do it at the f2f.
Tim: We could talk off-line [between chairs].
<timbl> HTML5 review
<timbl> ARCh of web apps
Tim: I could take html5 review and arch of webapps [to Jeff].
<timbl> Core mechanisms of the web
Noah: I called it "core
mechanisms of the Web." e.g. Mime, IRIs, etc...
... Architecture of webapps is new, html5 is new, but the Web runs on other things like http-bis, tcp/ip - we should also be spending time on that.
<ht> I think persistence falls in this category as well
<timbl> External dependencies of web arch - IRIs, TCP, HTTP bis? DNS
<timbl> We have to pick 2 or more things -- we can also work outside them
Jeni: I have edited the
introduction to try to reflect previous discussion. I would
really appreciate any feedback on scope in introduction.
... things I've done - expanded section on hosting of data in the web. and made revisions to section on caching / copying.
... structure of the document as a whole. Is that what the group wants the document to contain?
<noah> Tim: on the TAG priorities, it might be worth looking at the agenda for the Feb F2F? That indicates where we're putting energy: http://www.w3.org/2001/tag/2011/02/08-agenda
Jeni: what I've tried to do is to identify terminology that's used in licenses - how legislation talks about what servers on the web do - to be explicit about some of the issues that have been raised to the TAG. And then to be explicit about the aims of the document: provide an explanation of the way that material is published on the web to help inform people writing licenses and legislation
provide definitions of terms related to web publishing and linking that may be useful within licenses and legislation
describe the technical measures that websites can take to back up any restrictions that they place on the use of content they make available on the web
describe the mechanisms by which websites that reuse material can ensure they meet the restrictions on the use of that material, for example through attribution
Jeni: appreciate feedback on scope.
JAR: I think it's great. I like the direction it's going. I'm skeptical the attribution mechanism because it borders on giving legal advice.
I support it as well.
Tim: I support it. There is some question about whether W3C should support a policy. I think this document walks the right side of that line.
Noah: I support the document. The document doesn't say but could say what the consequences will be to the utility of the Web if certain policies were made.
<timbl> ** Definition of "representation" needs to match or not match that given in [webarch].
Noah: I'm not sure we should do
... I feel with deep linking, hosting, proxying, etc... we want to encourage people who are writing legislation to acknowledge that some restrictions that are impractical in order to keep the Web going. We do want to say some things along those lines. Explain the consequences of restrictions.
... The caching is a good example. If you were to pass a law that prohibited caching then you should know the web will slow down in the following ways or become more expensive in the following ways. Another one - a typical use case for the web is that people explore what is there in order to find what is there. [in the case of the nytimes paywall] you don't know until after you've clicked the link that you've used one of your 20 views...
<Zakim> jar, you wanted to ask whether 'shrink wrap' licenses are in scope e.g. legal question is whether american airlines 'do no link here' binding => consequence robots/browser
JAR: This issue goes back to deep linking - a bit different from copyright. How broad should this document be? We talked about shrinkwrap licenses -licenses that say "you should not link here".
Jeni: I kind of had that in the back of mind as something to mention.
<noah> To clarify what I said earlier: I think it's really crucial that those who pass laws understand how important it is that users do not, in general, know where a particular link is going to take them, and that it's fundamental to the Web that it should be OK to >try< to do a GET on any link. The burden must be on the servers hosting the resource to deny access if there is a copyright problem.
JAR: There's a legal question on
whether those contracts are binding. We can't answer that but
there are consequences / chilling effects on innovation.
... that's a theme that could be repeated over and over in the document.
+1 to JAR's comments.
<trackbot> ACTION-481 -- Ashok Malhotra to update client-side state document with help from Raman -- due 2011-05-10 -- OPEN
<trackbot> ACTION-541 -- Jeni Tennison to helped by DKA to produce a first draft of terminology about (deep-)linking etc. -- due 2011-04-26 -- OPEN
<noah> DKA: I'm happy to work on that aspect of the document
<ht> Someone thought they ought to say that they don't want you to link to it. . .
<ht> "they" is too diffuse
<ht> Some of AA undoubtedly _does_ want you to link to their pages
Tim: the push-back you'll get
legally is when there is a site that specifically makes its
money from advertising and the value of the site is only
linking to stolen content.
... would you also defend the site that links to stolen off-shore content?
<Zakim> noah, you wanted to say where I'd draw the line on linking
JAR: we can't answer the legal question but we can talk about the consequences...
Noah: There are lots of parts of the law when you presume the it's neutral unless there's additional context. E.g. naming someone vs. naming someone in the context of [a threat or incitement to violence].
<jar_> "It is the TAG's opinion that" is not the same as "here is what's legal or not"
Noah: illegal because of the way it's used not because of the URI.
Tim: that's an argument you will come across.
<jar_> The following legal position would / would not support the following technical goal ...
Noah - I think that is encompassed in the notion of speech.
<Yves> there are other (and existing) laws for that
<noah> ACTION-541 Due 2011-05-10
<trackbot> ACTION-541 Helped by DKA to produce a first draft of terminology about (deep-)linking etc. due date now 2011-05-10
<jar_> noah: The question is intent. Depends on whether someone knows what they are saying, when they say a URI
Noah: Ok - next call in a week. Can we bump the date on your action, Jeni?
