<p class='irc'><<cite>trackbot</cite>> Date: 19 August
2009</p>
<p class='irc'><<cite>Yves</cite>> like updating the
fragment in the URI bar when you seek manually in the
video?</p>
<p class='phone'><cite>Raphael:</cite> just Yves, Thierry,
Silvia and Raphael present on the call<br />
... no quorum :-(</p>
<p class='phone'><cite>Silvia:</cite> discussing my today's
blog post</p>
<p class='irc'><<cite>scribe</cite>> scribe: raphael</p>
<p class='phone'>Silvia ... i'm considering making a small
demo</p>
<p class='phone'><cite>scribe:</cite> not implementing the
protocol stuff the group is doing, but rather emulating the
visual effect on client / UA side<br />
... basically, the YouTube use case</p>
<p class='phone'><cite>Yves:</cite> +1, we want to demonstrate
how to bookmark a fragment of a video</p>
<p class='phone'><cite>Silvia:</cite> my implementation will be
based on javascript + perhaps the video element of HTML5</p>
<p class='irc'><<cite>Yves</cite>> about query: <a href=
"http://tools.ietf.org/html/draft-gregorio-uritemplate-03">http://tools.ietf.org/html/draft-gregorio-uritemplate-03</a></p>
<p class='irc'><<cite>Yves</cite>> might be useful</p>
<p class='irc'><<cite>nessy</cite>> <a href=
"http://lists.w3.org/Archives/Public/public-media-fragment/2009Aug/0011.html">
http://lists.w3.org/Archives/Public/public-media-fragment/2009Aug/0011.html</a></p>
<p class='phone'><cite>Silvia:</cite> I suggest we seriously
discuss the use of query vs fragment</p>
<p class='irc'><<cite>Yves</cite>> or link to a manifest
file somewhere</p>
<p class='irc'><<cite>Yves</cite>> or to a URI template
(if applicable)</p>
<p class='phone'><cite>Silvia:</cite> in case of query, how the
new resource can be linked to the original resource?</p>
<p class='phone'><cite>Raphael:</cite> perhaps using the link
header</p>
<p class='phone'><cite>Silvia:</cite> and the problem of the UA
getting the full duration of the parent resource in case of the
fragment, see ISSUE-11<br />
... do we need to define an extra header ?</p>
<p class='phone'>Yves, it is always in the case of a range
request</p>
<p class='phone'><cite>Yves:</cite> so no problem<br />
... for example, the server will serve, this is the bytes for
the range 10s - 20s / the full duration of the resource</p>
<p class='irc'><<cite>nessy</cite>> <a href=
"http://www.w3.org/2008/WebVideo/Fragments/wiki/UA_Server_HTTP_Communication">
http://www.w3.org/2008/WebVideo/Fragments/wiki/UA_Server_HTTP_Communication</a></p>
<p class='phone'><cite>Yves:</cite> correct, this is
incomplete, I will correct this wiki page</p>
<p class='phone'><cite>Raphael:</cite> I will take proper
action for closing the ISSUE-11 if the problem is addressed</p>
<p class='phone'>Great, that closes the ISSUE-11, at least for
the fragment</p>
<p class='phone'>I will email the group about that</p>
<p class='phone'><cite>Silvia:</cite> what we need to fix asap
is: the scheme syntax of media fragment, and the protocol
aspect (communication UA / server)</p>
<p class='phone'><cite>Yves:</cite> the ACTION-49 will be done
by the beginning of September</p>
<p class='phone'><cite>Raphael:</cite> yes, that will make the
work more concrete</p>
<p class='irc'><<cite>Yves</cite>> <a href=
"http://www.mnot.net/drafts/draft-nottingham-http-link-header-07.txt">
http://www.mnot.net/drafts/draft-nottingham-http-link-header-07.txt</a></p>
<p class='phone'><cite>Raphael:</cite> since our examples will
contain the full HTTP request and HTTP response</p>
<p class='phone'><cite>Silvia:</cite> I will write my use case
by the next telecon<br />
... and I will write a paragraph on the use of fragment vs
query ... among the lines of my blog post</p>
<p class='phone'><cite>Raphael:</cite> +1</p>
<p class='phone'>I want also we discuss the relationships
between the spatial dimension of Media Fragments and Image
Sprites, see <a href=
"http://lists.w3.org/Archives/Public/public-media-fragment/2009Jun/0002.html">
http://lists.w3.org/Archives/Public/public-media-fragment/2009Jun/0002.html</a></p>
<p class='phone'><cite>Silvia:</cite> perhaps finish the time
dimension first<br />
... but address that later</p>
<p class='phone'>I will create a new issue regarding this
point</p>
<p class='phone'><cite>Silvia:</cite> TPAC, worth to meet ?</p>
<p class='phone'><cite>Raphael:</cite> perhaps a accessible
media workshop colocated</p>
<p class='phone'><cite>Silvia:</cite> if workshop, mozilla will
fund me and I will be there</p>
<p class='phone'><cite>Raphael:</cite> in this case, I will
make it too and Yves will be there<br />
... might worth to have then a meeting, perhaps using Media
Annotations arrangement</p>
<p class='phone'>ACTION-96?</p>
<p class='irc'><<cite>trackbot</cite>> ACTION-96 -- Yves
Lafon to make change to temporal-optional-comma specification

<p class='phone'>Question: do we need also editUnits, <a href=

http://lists.w3.org/Archives/Public/public-media-fragment/2009Jul/0018.html</a>
?</p>
<p class='phone'><cite>Silvia:</cite> my problem with editUnit,
is that this is container specific<br />
... even worse, this is encoding specific<br />
... I can write a reply about that<br />
... editing the WD directly in the cvs ?<br />
... capture the discussion within the wiki but update the main
document that contains the spec in the cvs</p><a name=
"action01" id="action01"></a>
<p class='irc'><<cite>scribe</cite>>
<strong>ACTION:</strong> Silvia to update the wiki + cvs

<p class='phone'>we need to write a small IETF draft for IANA
consideration</p>
<p class='phone'>we need to make a plan for that</p>
<p class='phone'><cite>Yves:</cite> first, get a good story
from our document, and then the IETF document will just link to
our document</p>
<p class='phone'>close ACTION-89</p>
<p class='irc'><<cite>trackbot</cite>> ACTION-89 Find out
more about fragment identifier registration closed</p>
<p class='phone'>I will open a new ISSUE to remind us that we
need to write a IETF draft for proposing how to register the
fragment scheme for all media types</p>
<p class='phone'><cite>Yves:</cite> this IETF draft should
contain a how-to register the fragment spec for media
fragments<br />
... and we should ask for a template of what does it mean when
we come accross a media fragment</p>
<p class='phone'><cite>Silvia:</cite> this is a different issue
... something to consider</p>
<p class='phone'><cite>Raphael:</cite> I will make another
issue<br />
