<h3 id="item01">1 admin</h3>
<p class="phone"><cite>erik:</cite> accept minutes<br />
... postpone f2f discussion until next call</p>

<h3 id="item02">2 specification</h3>
<p class="phone"><cite>erik:</cite> first details as pointed out by Thierry</p>
<p class="phone"><cite>Thierry:</cite> don't worry, I will do that.<br />
... boilerplate, uri, etc.<br />
... have also communicated with Philippe</p>
<p class="phone"><cite>erik:</cite> I will send draft email (to chairs), please
comment</p>
<p class="phone"><cite>Thierry:</cite> that email can go out next morning</p>
<p class="phone"><cite>erik:</cite> ok<br />
... that is spec document. How about note?</p>
<p class="phone"><cite>Thierry:</cite> much simpler, already exists, so no
transition needed<br />
... But need to cater for pubrules, there are currently soe broken URIs.</p>
<p class="phone"><cite>erik:</cite> ok, I will take care of it.<br />
... On to the spec. Silvia, can you explain section 5?</p>
<p class="irc"><<cite>davy</cite>> <a
href="http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-spec/#processing">http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-spec/#processing</a></p>
<p class="phone"><cite>silvia:</cite> goes over section naming and content (for
5.1)</p>
<p class="irc"><<cite>Yves</cite>> I would note that error handling might
get in the way of future upgrades/other use of similar syntax</p>
<p class="phone"><cite>silvia:</cite> 5.2 has more substantial changes, is now
in line with section 3</p>
<p class="irc"><<cite>conrad</cite>> yes i have lots of issues but i
won't delay publication with them, they can wait for a future revision</p>
<p class="phone"><cite>silvia:</cite> Finally 5.3 is in sync with 3.5<br />
... 5.3 needs work, but this should delay publication</p>
<p class="phone"><cite>erik:</cite> are the ABNF errors fixed?</p>
<p class="irc"><<cite>silvia</cite>> npttime = ( 1*DIGIT [ "." 1*DIGIT ]
[timeunit] ) /</p>
<p class="irc"><<cite>silvia</cite>> ( 1*DIGIT ":" 2DIGIT ":" 2DIGIT [
"." 1*DIGIT] )</p>
<p class="irc"><<cite>silvia</cite>> "." 1*DIGIT -> RTSP: "."
*DIGIT</p>
<p class="irc"><<cite>Yves</cite>> the change can wait after
publication</p>
<p class="phone"><cite>silvia:</cite> I think it is fixed</p>
<p class="irc"><<cite>Yves</cite>> we need to check other definitions as
well</p>
<p class="irc"><<cite>davy</cite>> FYI: <a
href="http://www.ietf.org/rfc/rfc2326.txt">http://www.ietf.org/rfc/rfc2326.txt</a>,
section 3.6</p>
<p class="irc"><<cite>Yves</cite>> agree with Jack section 5.3 is just
not needed. It's a normal GET on a URI</p>
<p class="irc"><<cite>Yves</cite>> ah jack was talking about 5.1.3</p>
<p class="irc"><<cite>davy</cite>> I agree with Jack too</p>
<p class="phone"><cite>jack:</cite> hates 5.1.3, handling of over-specified
dimensions</p>
<p class="phone"><cite>yves:</cite> agrees.</p>
<p class="phone"><cite>jack:</cite> should we add a note to this section,
saying that we are rethinking this section?</p>
<p class="phone"><cite>yves:</cite> can do.</p>
<p class="phone"><cite>silvia:</cite> ok, will add a note that this is
contentious.</p>
<p class="phone"><cite>erik:</cite> more comments?</p>
<p class="phone"><cite>yves:</cite> some issues with header syntax</p>
<p class="irc"><<cite>tmichel</cite>> Sylvia, let me know when you are
done with the editing. Then We freeze the document.</p>
<p class="phone"><cite>yves:</cite> but: difficult to do without f2f</p>
<p class="phone"><cite>conrad:</cite> Silvia, Davy and me are going to be at
FOMS in NZ in January</p>
<p class="irc"><<cite>conrad</cite>> foms-workshop.org</p>
<p class="phone"><cite>erik:</cite> conrad, comments on state of the
document?</p>
<p class="phone"><cite>conrad:</cite> nothing in particular</p>
<p class="phone"><cite>erik:</cite> should we have a f2f soon?</p>
<p class="phone"><cite>yves:</cite> yes</p>
<p class="phone"><cite>eri:</cite> action points</p>
<p class="irc"><<cite>davy</cite>> action-123?</p>
<p class="irc"><<cite>trackbot</cite>> ACTION-123 -- Yves Lafon to come

<p class="phone"><cite>silvia:</cite> Something like ROE is needed</p>
<p class="irc"><<cite>Yves</cite>> +1 to jack</p>
<p class="phone"><cite>jack:</cite> don't want to discuss merits of ROE right
now, but think it's outside our charter</p>
<p class="phone"><cite>silvia:</cite> agrees. But should point out it exists</p>
<p class="phone"><cite>davy:</cite> agrees.<br />
... Clients could also use Media Annotations work to interface to it</p>
<p class="phone"><cite>erik:</cite> Jack, did you write up on distinction?</p>
<p class="phone"><cite>jack:</cite> uhm...</p>
<p class="phone"><cite>silvia:</cite> I think that was never intended. Just
reaction to my post.</p>
<p class="phone"><cite>erik:</cite> ok, let's close this then</p>

<p class="phone"><cite>silvia:</cite> COnrad suggests handling track an id
completely different from rest.<br />
... I don't agree.</p>

need to discuss.</p>
