<p class='phone'><cite>Silvia:</cite> no objection</p>
<p class='phone'><cite>Michael:</cite> no objections</p>
<p class='phone'><cite>Silvia:</cite> I agree that currently,
codecs do not allow to address spatial fragment without
transcoding<br />
... so agree, it should happen with a query</p>
<p class='irc'><<cite>silvia</cite>> spatial fragment
retrieval cannot be done with byte ranges right now because
current media formats and codecs don't allow it</p>

<p class='phone'><cite>Michael:</cite> the question is really,
can we really have an automated test suite ?<br />
... if not, then corrib is of little use</p>
<p class='phone'><cite>Raphael:</cite> my proposal would be to
change the action 146 assigned to Jack to a thorough review of
<a href=

http://www.w3.org/2008/WebVideo/Fragments/wiki/TemporalDimension</a><br />

- Report to the group whether such an approach from RDFa test

<p class='irc'><<cite>mhausenblas</cite>> <a href=
"http://ngrep.sourceforge.net/">http://ngrep.sourceforge.net/</a></p>
<p class='irc'><<cite>silvia</cite>> ngrep or tcpdump are
good tools for monitoring connections</p>
<p class='phone'><cite>Silvia:</cite> I think whatever plugin
you have for the browser, testing if the plugins does the real
thing can only be tested with one of these tools</p>
<p class='phone'><cite>Erik:</cite> maybe we can make a summer
project for this</p>
<p class='irc'><<cite>silvia</cite>> what you would
require is a commandline tool that pulls in what is an expected
HTTP exchange sequence from a media fragment request (which
could come from corrib) and check with what actually goes over
the wire</p>
<p class='irc'><<cite>silvia</cite>> those tools can help
with monitoring what actually goes over the wire</p>

<p class='phone'><cite>Raphael:</cite> I think as soon as a
fragment is requested, we cannot have a 200 answer, so MUST be
a 206<br />
... I think if there is a #t= ... then a Range request should
be issued, even if the fragment happens to be the entire
resource</p>
