    Yves: wonder if the same thing can be obtained with firebug

    close action-186

    <trackbot> ACTION-186 Send his list of test cases to the mailing
    list for understanding how browsers handle %-encodded and
    html-encoded URL closed

    action-187?

    <trackbot> ACTION-187 -- Philip Jšgenstedt to start a new thread
    about extensibility of the Media Fragments in order to get consensus
    by next week -- due 2010-09-29 -- OPEN

    <trackbot>
    [20]http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/187

      [20] http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/187

    raphael: people agreed with proposal (2) of Philip

    yves: would like to know the opinion of Jack

    raphael: first decide which proposal, afterwards decide how it is
    written in the spec

    yves: just against the fact that saying that all key-value pairs are
    media fragments

    raphael: on condition is that you need to have keys that we
    understand
    ... if this is not the case, it's not a media fragment

    yves: not in favour, but also not against this

    close action-187

    <trackbot> ACTION-187 Start a new thread about extensibility of the
    Media Fragments in order to get consensus by next week closed

    raphael: philip would like to distinguish between validity and
    parsing

    yves: if we have grammar explaining what should be there, and a
    parsing algorithm, that's fine

    <raphael> Is this grammar could be
    [21]http://lists.w3.org/Archives/Public/public-media-fragment/2010Au
    g/0005.html

      [21] 
http://lists.w3.org/Archives/Public/public-media-fragment/2010Aug/0005.html

    yves: this is not a grammar
    ... it's a general approach to parse key-value pairs

    raphael: the grammar we currently have, will be kept of course

    <Yves> I propose, keep the current grammar and add the extension
    point, _and_ define a parsing algorithm for those who need it

    <Yves> mediasegment = namesegment / axissegment

    <Yves> axissegment = ( timesegment / spacesegment / tracksegment )

    <Yves> *( "&" ( timesegment / spacesegment / tracksegment )

    <Yves> ;

    <Yves> => add extensionsegment there

    yves: a mediasegment can't be only an extensionsegment

    <raphael> Yves propose that: mediasegment = namesegment /
    axissegment / extensionsegment + prose to state that a media segment
    cannot be only an extension segment

    yves: we have to state that extensions should remain compatible with
    the current spec
    ... e.g., bounding box (through xywh) as fallback for an arbitrary
    shape (through ref)

    <Yves> extensionsegment = extensionname '=' extensionvalue

    <raphael> extensionsegment = extensionprefix '=' extensionparam

    <Yves> issue is with extensions that conflict with already defined
    axis, like 'ref' being impacting the spatial dimension defined by
    'xywh'

    raphael: top-level production rules of the grammar should be in de
    document as well, not only in the appendix
    ... in section 4.3.5 or 4.1

    <scribe> ACTION: troncy to put the top-level production rules back
    into the document (in section 4.3.5 or 4.1) [recorded in
    [22]http://www.w3.org/2010/09/29-mediafrag-minutes.html#action02]

    <trackbot> Created ACTION-189 - Put the top-level production rules
    back into the document (in section 4.3.5 or 4.1) [on RaphaŽl Troncy
    - due 2010-10-06].

    raphael: still missing is a paragraph how things should be parsed
    ... I will ask Philip regarding this issue

    close action-187

    <trackbot> ACTION-187 Start a new thread about extensibility of the
    Media Fragments in order to get consensus by next week closed

    action-173?

    <trackbot> ACTION-173 -- Yves Lafon to produce the code that will
    check the grammar of both the URI syntax and the Headers syntax --
    due 2010-06-22 -- OPEN

    <trackbot>

    yves: not done yet for the header syntax

PUBLIC COMMENTS

    <raphael> ACTION-184?

    <trackbot> ACTION-184 -- Yves Lafon to email Chris the reply on when
    to send the range header -- due 2010-09-15 -- OPEN

    <trackbot>

    close action-184

    <trackbot> ACTION-184 Email Chris the reply on when to send the
    range header closed

    raphael: should we use the bug tracker for LC comments?

    yves: a manual approach should be feasible (e.g., manually building
    an HTML table)

    raphael: suggest to start with manual approach, when a lot of
    comments are coming, we might consider using the bug tracker

    <raphael> ACTION-167?

    <trackbot> ACTION-167 -- Erik Mannens to find licence free movies
    for the automatic test suite ... starting with Elephant Dreams and
    the creative commons -- due 2010-06-02 -- OPEN
