ACTION-407?

<trackbot> ACTION-407 -- Henry S. Thompson to propose an update to DanC's prose from http://lists.w3.org/Archives/Public/public-html/2010Feb/0878.html to explicitly reference or encorporate the HTML history, similarly to the way 2854 does -- due 2010-04-13 -- OPEN

<trackbot> http://www.w3.org/2001/tag/group/track/actions/407

<noah> http://lists.w3.org/Archives/Member/tag/2010Apr/0027.html

HT: there was a lot of agreement at our F2F, and I sent an email making a proposal

<DanC> http://www.w3.org/mid/f5bochmffrb.fsf@calexico.inf.ed.ac.uk

(see above)

<ht> http://lists.w3.org/Archives/Member/tag/2010Apr/0027.html

<noah> Discussing http://lists.w3.org/Archives/Member/tag/2010Apr/0027.html

HT: It differs from previous text in 3 ways
... I added a short para to the introduction, referring to the previous RFC
... and notes that this specification updates RFC2854
... have adopted Tim's wording as it seemed closest to consensus
... added the 'licenses' language

<DanC> (I wonder whether introducing "the HTML family" is the shortest path to the target. I don't mind it much, but I wonder what others in the HTML WG think)

<jar> Larry objected to "licenses"

HT: replaced the published specification paragraph from the original with new text

JAR: representing Larry's view that a MIME type doesn't license anything

TVR: I am happy with this text

<noah> Larry's concern was expressed here: http://www.w3.org/2001/tag/2010/04/01-minutes.html#item02

JAR: I spent some time to think of alternative text, but couldn't find anything better

NM: I understand the concern, but am happy with the text

DC: Larry wanted to take up the bigger issue

<DanC> .. and we have

NM: I am not hearing anyone objecting to this text
... I propose that this text (http://lists.w3.org/Archives/Member/tag/2010Apr/0027.html) should be sent to the HTML WG on behalf of the TAG

HT: In response to the relevant HTML bug, referenced in the email

<DanC> noah's msg http://www.w3.org/mid/OFEFE75A7B.92080902-ON852576FA.0060BD12-852576FA.0060DC6B@lotus.com

<DanC> cites http://www.w3.org/html/wg/tracker/issues/4 and http://www.w3.org/html/wg/tracker/actions/172

NM: how should this relate to HTML issue-4, issue-84 and action-172?

<DanC> the relevant issue seems http://www.w3.org/html/wg/tracker/issues/53 mediatypereg Need to update media type registrations

<noah> . RESOLUTION: the TAG will propose to the HTML WG the revisions suggested in http://www.w3.org/2001/tag/2010/04/01-minutes.html#item02 as a resolution to your ISSUE-53 (note that we, perhaps mistakenly, had previously suggested this would relate to HTML ISSUE 4)

<noah> RESOLUTION: the TAG will propose to the HTML WG the revisions suggested in http://lists.w3.org/Archives/Member/tag/2010Apr/0027.html is a resolution to your ISSUE-53 (note that we, perhaps mistakenly, had previously suggested this would relate to HTML ISSUE 4)

<DanC> close enough. +1

<noah> RESOLUTION: the TAG will propose to the HTML WG the revisions suggested in http://lists.w3.org/Archives/Member/tag/2010Apr/0027.html as a resolution to your ISSUE-53 (note that we, perhaps mistakenly, had previously suggested this would relate to HTML ISSUE 4)

NM: any objections?

HT: will take the action

<DanC> (close 407 now)

<DanC> (oh well)


. ACTION ht to fulfill the resolution to propose text from email related to ACTION-407

<DanC> (ah. do this under 407. even better.)

<DanC> action-407 due next week

<trackbot> ACTION-407 Propose an update to DanC's prose from http://lists.w3.org/Archives/Public/public-html/2010Feb/0878.html to explicitly reference or encorporate the HTML history, similarly to the way 2854 does due date now next week

ACTION-407 ht to propose related text from http://lists.w3.org/Archives/Member/tag/2010Apr/0027.html to HTML WG

resource/representation terminology

ACTION-389?

<trackbot> ACTION-389 -- Dan Connolly to take Dan's proposal on resource/representation and turn it into a change proposal -- due 2010-04-06 -- PENDINGREVIEW

<trackbot> http://www.w3.org/2001/tag/group/track/actions/389

<DanC> I mostly accepted editor's proposal: http://lists.w3.org/Archives/Public/public-html/2010Apr/0367.html

DC: made a proposal, and editor responded with counter-proposal

NM: do they use the term resource to mean "your choice of the two" (ie. resource, and representation)

DC: yes

NM: should we ask for the text to indicate that the term is used to refer to either of those two concepts

TBL: closing this up and getting something said is important

<DanC> [[

<DanC> > > Where that specification speaks of a URI that identifies a resource whose state is communicated via a typed byte sequence called a representation, we simply say that a URL identifies a resource, which is a typed byte sequence; the indirection is not mentioned in this specification.

<DanC> ]]

DC: I suggested the above originally
... He's already committed the change as documented in http://lists.w3.org/Archives/Public/public-html/2010Apr/0367.html

NM: propose to close ACTION-389

<DanC> close action-389

<trackbot> ACTION-389 Take Dan's proposal on resource/representation and turn it into a change proposal closed

Distributed extensibility

ACTION-357?

<trackbot> ACTION-357 -- Henry S. Thompson to elaborate the DPD proposal to address comments from #xmlnames and tag f2f discussion of 2009-12-10, particularly wrt integration with XML specs and wrt motivation -- due 2010-03-31 -- OPEN

<trackbot> http://www.w3.org/2001/tag/group/track/actions/357

HT: action may have been overtaken by work in the WG, and I haven't yet followed-up

<DanC> ACTION-357 due next week

<trackbot> ACTION-357 Elaborate the DPD proposal to address comments from #xmlnames and tag f2f discussion of 2009-12-10, particularly wrt integration with XML specs and wrt motivation due date now next week

<trackbot> http://www.w3.org/2001/tag/group/track/actions/406

<DanC> they're listed under 41 in http://dev.w3.org/html5/status/issue-status.html

NM: now 5 change proposals suggested

DC: any of them close to yours HT?

<ht> I just got cut off

<ht> I see that that proposal references mine, but cannot confirm whether it builds on it in any significant way

<DanC> which one? title?

<ht> Proposal X, I think

<ht> Yes

<ht> http://www.w3.org/html/wg/wiki/ChangeProposals/fixedprefixlikexml

<ht> I have to leave early today, conflict, sorry

NM: Don't see some of the original proposals we inspected (the Microsoft one, Liam's) in that list

<ht> ACTION-407: ht to propose related text from http://lists.w3.org/Archives/Member/tag/2010Apr/0027.html to HTML WG

<trackbot> ACTION-407 Propose an update to DanC's prose from http://lists.w3.org/Archives/Public/public-html/2010Feb/0878.html to explicitly reference or encorporate the HTML history, similarly to the way 2854 does notes added

<ht> trackbot, close ACTION 407

<trackbot> Sorry, ht, I don't understand 'trackbot, close ACTION 407'. Please refer to http://www.w3.org/2005/06/tracker/irc for help

<ht> trackbot, close ACTION-407

NM: I would hope we would look at these proposals - do they build on the previous work or not?

<DanC> under 41 http://dev.w3.org/html5/status/issue-status.html

<DanC> ^ where the 5 proposals are listed

DC: didn't see anything that said "use XML namespaces as much as you can"
... if there was an alternate syntax to XMLNS, that might make sense...

JK: what is the rationale that would counter Hixie's "null" change proposal?

NM: rationale well-known in the community - I presented some of these at TPAC

TBL: could we take some real-world examples and start from there?

<DanC> (FBML is written up in http://intertwingly.net/blog/2007/08/02/HTML5-and-Distributed-Extensibility )

<timbl> The examples -

<timbl> 1) FBML - cut out an example, this is a specific website

<timbl> 2) MathML - this is a community.

<timbl> 3) A vendor -- MSword? WebOS?

DC: Palm WebOS?

<timbl> 4) A set of vendors making a new market - XForms?

<DanC> Palm webOS approach to HTML extensibility: x-mojo-* http://www.w3.org/QA/2009/02/palm_webos_approach_to_html_ex.html

<timbl> x-majo-*

<timbl> x-mojo-* ?

<timbl> X_DASH CONSIDERED HARMFUL

<DanC> yes, tim, that was mnot's reply: http://www.mnot.net/blog/2009/02/18/x-

<timbl> Stop it with the X- Already! ++

so basically, one part of the rationale is to prevent overlap in extensions between the browser vendors and those who process HTML but are not UAs

from Sam Ruby's blog: "FBML isn’t intended to be directly processed by browsers, but that shouldn’t preclude it from being processed by other HTML5 tools, everything from sanitizers to conformance checkers to pretty printers, to search engines."

TVR: we are spinning our wheels
... XMLNS is ugly, and we could potentially fix it
... don't feel comfortable designing an ad-hoc solution though

NM: designing something ourselves would be a serious effort

TVR: XMLNS is designed, these proposals are better than current proposal
... I wonder what impact we can have on this solution?

NM: what would you like the TAG to do?

TVR: Fix XML Namespaces
... if you have palatable NSs in XHTML, then XHTML and HTML can eventually converge

NM: would you expect XML processors to change?

TVR: don't know

NM: would you take an action to organize this work TVR?

TBL: if you try and change XML, you'll have problems because of the deployed infrastructure

TVR: backward compatibility is important
... believe that we should pursue at least one of the proposals already on the table

<scribe> ACTION: JohnK to read 4 distributed extensibility proposals and summarize them w.r.t. proposals TAG has discussed to date [recorded in http://www.w3.org/2010/04/15-tagmem-minutes.html#action01]

<trackbot> Sorry, couldn't find user - JohnK

<scribe> ACTION: john to read 4 distributed extensibility proposals and summarize them w.r.t. proposals TAG has discussed to date [recorded in http://www.w3.org/2010/04/15-tagmem-minutes.html#action02]

<trackbot> Created ACTION-427 - Read 4 distributed extensibility proposals and summarize them w.r.t. proposals TAG has discussed to date [on John Kemp - due 2010-04-22].

<DanC> (I think http://www.w3.org/html/wg/wiki/ChangeProposals/html:xmlns is the best of those on the table. if we need to pick one urgently by way of saying "something is better than nothing", that one.)

<DanC> ACTION: Raman to sketch a plan to contact stakeholders regarding distributed extensibility [recorded in http://www.w3.org/2010/04/15-tagmem-minutes.html#action03]

<trackbot> Created ACTION-428 - Sketch a plan to contact stakeholders regarding distributed extensibility [on T.V. Raman - due 2010-04-22].

ACTION-427 due: may 1st

ACTION-427: due may 1st

HTML5 co-ordination with HTML WG

NM: sent http://lists.w3.org/Archives/Public/www-tag/2010Apr/0064.html

<noah> http://lists.w3.org/Archives/Public/www-tag/2010Apr/0064.html

Web Application Architecture

NM: we have an opportunity here to seriously move on this work
... prior to next face to face

<DanC> ACTION-416 due +3weeks

<trackbot> ACTION-416 Work on diagrams in "From Server-side to client-side" section of webapps material due date now +3weeks

AM: work into the existing template structure?

TVR: start with separate files and then integrate

NM: see the advantages of both, and suggest we don't worry about it too much now

<DanC> (very unusual? well, maybe... but (a) less and less so, and (b) unusual cases make interesting study)

JAR: I love accumulating use-cases
... can assemble later

<DanC> yes, raman, very interesting study of the BBC iPlayer thingy

<DanC> http://lists.w3.org/Archives/Public/www-tag/2010Apr/att-0072/bbc-iplayer-and-web-arch.html

<DanC> aka http://xml-applications.blogspot.com/2010/04/on-web-applications-web-architecture.html

<noah> Advertised in email at: http://lists.w3.org/Archives/Public/www-tag/2010Apr/0072.html

<DanC> (bonus points for archiving a copy in www-tag, raman)

NM: I feel this piece says "this stuff happens" but I'd like to say more
... we could say, "here's good practice"
... an alternative is to say "let's explain some of the tradeoffs between how this is done and other ways it could be done"

AM: would you have written the application differently?

TVR: I don't understand all of their design constraints so can't really say

<noah> BTW, we aren't going to get to the review, but there are >30 overdue actions in tracker. Yes, we can arbitrarily bump the dates, but I'd much prefer you all fix them to have realistic dates.

<noah> >30 overdue is bad.

<noah> 2 mins to go

TVR: some of the design constraints regarding how they release the content may have affected their solution
... they mint very simple, clean identifiers

<noah> 1 min to go

TVR: where it gets ugly, is when you load the content into the borwser and that's where the complexity comes in
... just knowing the MIME type doesn't help you

NM: we'll have a call next week
... please clean up your action items!

<noah> We are adjourned.

ADJOURN

<timbl> Ramin, do you have an example URI you could drop into IRC plaease?

<noah> Tim, I >think< there are some in his blog entry, linked above
