    [14]http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/224

      [14] http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/224

    First one: Silvia who asked for using the js library for having a
    validator

    <scribe> ACTION: thomas to develop the validator page using his js
    library for media fragments [recorded in
    [15]http://www.w3.org/2011/06/22-mediafrag-minutes.html#action01]

    <trackbot> Created ACTION-228 - Develop the validator page using his
    js library for media fragments [on Thomas Steiner - due 2011-06-29].

    Second one:
    [16]http://lists.w3.org/Archives/Public/public-media-fragment/2011Ma
    y/0037.html

      [16] 
http://lists.w3.org/Archives/Public/public-media-fragment/2011May/0037.html

    scribe: from Chris
    ... except for the loop, all other comments have been adressed

    Chris: I confirm

    Third one: Boris and Fantasai

    The CSS3 spec mentions media fragment:
    [17]http://dev.w3.org/csswg/css3-images/#url

      [17] http://dev.w3.org/csswg/css3-images/#url

    The SVG 1.1 spec: [18]http://www.w3.org/TR/SVG/struct.html#Overview

      [18] http://www.w3.org/TR/SVG/struct.html#Overview

    Silvia: I would like to come back to Chris bugs ... we confirmed a
    number of things, but what has been implemented already?
    ... but Ian's resolution of some HTML5 bugs goes against this
    ... so what has been actually implemented

    Chris: I might have have a version to release this Friday

    <doublec> silvia: what bugs are different to what's discussed in the
    email?

    Yves: at the last TAG meeting, we discuss fragments in general
    ... the SVG fragment itself (viewport) though it is not a XPointer
    ... the fragment as defined in XML
    ... the image that re-uses our media fragment syntax

    <Yves>
    [19]http://www.w3.org/TR/SVG/linking.html#SVGFragmentIdentifiers

      [19] http://www.w3.org/TR/SVG/linking.html#SVGFragmentIdentifiers

    SVGview has a XPointer like syntax

    Yves: the fact we are always using an equal sign, means we don't
    generate XML id, so no conflict possible
    ... not something that can be interpreted in different ways by 2
    different processors

    Raphael: should we discuss with CSS or SVG or Hypertext CG?

    Yves: go for CG
    ... point out the 2 threads, and let us know if there are issues
    ... so a request for review from the CG

    <scribe> ACTION: troncy to bring the CSS/SVG/Media Fragments
    possible issues to the CG group [recorded in
    [20]http://www.w3.org/2011/06/22-mediafrag-minutes.html#action02]

    <trackbot> Created ACTION-229 - Bring the CSS/SVG/Media Fragments
    possible issues to the CG group [on Raphaël Troncy - due
    2011-06-29].

    ACTION-224?

    <trackbot> ACTION-224 -- Raphaël Troncy to send a reply to the 4
    commenters -- due 2011-06-15 -- OPEN

    <trackbot>

    close ACTION-224

3. HTML5 Bugs

    [22]http://www.w3.org/Bugs/Public/show_bug.cgi?id=10723

      [22] http://www.w3.org/Bugs/Public/show_bug.cgi?id=10723

    Should a UA stop playing at the end of a media fragment

    Raphael: stop or actually pause depending on the implementation?

    This bug is WONTFIX stage, and points to
    [23]http://www.w3.org/Bugs/Public/show_bug.cgi?id=12643

      [23] http://www.w3.org/Bugs/Public/show_bug.cgi?id=12643

    Chris: I can re-open the bug once my implementation is here

    Raphael: I'm for re-opening the bug once we have example of
    implementations that contradict Hixie's thought ... e.g. Mozilla and
    Opera

    [24]http://www.w3.org/Bugs/Public/show_bug.cgi?id=12643

      [24] http://www.w3.org/Bugs/Public/show_bug.cgi?id=12643

    Raphael: a new bug

    Silvia: unsure it concerns that much media fragment

    [25]http://www.w3.org/Bugs/Public/show_bug.cgi?id=12426

      [25] http://www.w3.org/Bugs/Public/show_bug.cgi?id=12426

    Raphael: looping over media fragments
    ... for hixie, looping means playing from the start of the media,
    ignoring the fragment

    Silvia: Thomas sent numerous use cases

    <Yves> but with the fragment, the requested media is the fragment

    Raphael: indeed,
    [26]http://lists.w3.org/Archives/Public/public-media-fragment/2011Ju
    n/0038.html

      [26] 
http://lists.w3.org/Archives/Public/public-media-fragment/2011Jun/0038.html

    Chris: we wait for the spec clarification

    Silvia: as soon as there is user interaction, the media fragments
    goes away
    ... I'm not sure loop will be widely implemented anyway ... since
    most of the behavior could be done in js

    <silvia> … I'm in support of deprecating the loop attribute
    altogether :-)

    Raphael: Thomas wants to re-open this bug
    ... Chris and Philip think that loop should be deprecated anyway

    [27]http://www.w3.org/Bugs/Public/show_bug.cgi?id=12425

      [27] http://www.w3.org/Bugs/Public/show_bug.cgi?id=12425

    <Yves> silvia, it might be a possibility yes

    Should the UI (and UX) playing a temporal media fragment be
    standardized?

    <Yves> I agree with Hixie that this is UA specific

    Raphael: I think Hixie is right, this is not really our business

    Silvia: I agree with that too

    Raphael: I will close this bug, we accept this resolution

    [28]http://www.w3.org/Bugs/Public/show_bug.cgi?id=12427

      [28] http://www.w3.org/Bugs/Public/show_bug.cgi?id=12427

    Raphael: Hixie is saying that this depends on the MIME type of the
    resource so not HTML5 business

    Silvia: don't do anything, depends on discussion with CSS/SVG group
    discussions

    Raphael: I did generate diff files

    [29]http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-spe
    c/lc1-lc2-diff.htm

      [29]

4. Splitting out the spec?

    Against splitting: Silvia, Raphael

    For splitting: Yves (rationale = don't put several ways of doing the
    same thing)

    <Yves> yes, as it is bad for interop

    <davy> I'm also against splitting the spec

    Raphael: Philip seems to want that the HTTP part gets out of the
    spec

    <Yves> section 5.2

    <doublec> sorry phone problems

    <doublec> pointer to thread about split?

    Chris:
    [31]http://lists.w3.org/Archives/Public/public-media-fragment/2011Ju
    n/0021.html

      [31] 
http://lists.w3.org/Archives/Public/public-media-fragment/2011Jun/0021.html

    <silvia> how about doing a questionnaire?

    <Yves> +1

    <scribe> ACTION: troncy to open a questionnaire for splitting out or
    not (the section 5.2 of) the spec [recorded in
    [32]http://www.w3.org/2011/06/22-mediafrag-minutes.html#action03]

    <trackbot> Created ACTION-230 - Open a questionnaire for splitting
    out or not (the section 5.2 of) the spec [on Raphaël Troncy - due
    2011-06-29].

5. AOB

    Raphael: I will put the media fragments list in cc for the exchange
    with the hypertext CG
    ... goal is then to answer the questionnaire and vote for
    transitioning next week
