<p class='irc'>&lt;<cite>trackbot</cite>&gt; Created ACTION-58
- Write introduction [on Silvia Pfeiffer - due 2009-04-15].</p>
<p class='phone'><cite>raphael:</cite> discussion on order of
the first three sections</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; Silvia: i need to
revisit the framework, side conditions</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; ... re: issue with
transcoding</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; ... this should go
first</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; ... and then talk
about the use cases and scenarios and ultimately, the
dimensions</p>
<p class='phone'><cite>jackjansen:</cite> if requirements move
up, we need something that gets people in the right frame of
mind</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; Jack: put the
requirements first might break the flow of the reading</p>
<p class='phone'><cite>Silvia:</cite> most sections are still
independent blocks<br />
... we need lead-over text<br />
... introduction will set the stage, requirements set the
framework</p>
<p class='phone'><cite>Jack:</cite> maybe move use cases into
appendix</p>
<p class='phone'><cite>raphael:</cite> use cases are core to
the understanding or our challenges and provide motivation for
the dimensions<br />
... might be interesting to move the "requirements" up - might
be renamed to "side conditions"</p>
<p class='phone'><cite>Jack:</cite> agrees to move up "side
conditions"<br />
... requirements are really section 5</p>
<p class='phone'><cite>raphael:</cite> new order is 1, 2, 4, 3,
5<br />
... rename 4 -&gt; side conditions<br />
... rename 5 -&gt; requirements</p>
<p class='phone'><cite>nessy:</cite> agree</p>
<p class='phone'><cite>Jack:</cite> agree</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; +1</p>
<p class='irc'>&lt;<cite>erik</cite>&gt; what about typical UC
per axis (temporal/spatial/track/named) to get the reader
acquainted with the problems (and special cases to
appendix)?</p><a name="action03" id="action03"></a>
<p class='irc'>&lt;<cite>scribe</cite>&gt;
<strong>ACTION:</strong> silvia to make these changes and other
changes to sections 1-5 [recorded in <a href=
"http://www.w3.org/2009/04/08-mediafrag-minutes.html#action03">http://www.w3.org/2009/04/08-mediafrag-minutes.html#action03</a>]</p>
<p class='irc'>&lt;<cite>trackbot</cite>&gt; Created ACTION-59
- Make these changes and other changes to sections 1-5 [on
Silvia Pfeiffer - due 2009-04-15].</p>
<p class='phone'>raphael will make structural changes to WD
directly after the teleconf</p>
<p class='phone'><cite>scribe:</cite> silvia can then work on
it when she has time</p>
<p class='phone'><cite>erik:</cite> there are a lot of use
cases and it may be interesting to move some to appendix</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; Erik: i wonder if
the individual use cases should be ordered differently,
following the various dimensions: time, space, track, name</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; Silvia: I think it
is better to group them as they are, by functionality</p>
<p class='phone'><cite>erik:</cite> they make for fast reading
and need to be part of the reading flow</p>
<p class='phone'><cite>raphael:</cite> what about moving the
out-of-scope cases into a separate section</p>
<p class='phone'><cite>jack:</cite> I like it that the use
cases are ordered by usage<br />
... problem is that there are so many and they slow down
reading speed<br />
... 17 different use cases may be too much detail</p>
<p class='phone'><cite>raphael:</cite> original charter had 2
documents - a use cases &amp; requirements ... and a technology
document<br />
... we now have all in one document<br />
... we can later split documents again if it is too much to
read<br />
... can discuss at F2F<br />
... should leave it for now<br />
... so we have the current status together in a single
document</p>
<p class='phone'><cite>jack:</cite> ok leave it as is</p>
<p class='phone'><cite>nessy:</cite> agree</p>
<p class='phone'><cite>raphael:</cite> section 5<br />
... replace the numbers with req-xx<br />
... and move the table to an appendix</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; Raphael: replace
the 1,2,3 in the fitness table by human readable labels: fit,
partial, etc.</p>
<p class='phone'><cite>jack:</cite> instead of having the table
5.5, it makes more sense to list the types of capabilities
containers have</p>
<p class='phone'>nessy to add a note to the table &amp; running
text that we ask people for input to the table to complete
it</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; Silvia: add also an
editorial note in the main text to warn the commnity we need
their input to complete this table</p>
<p class='phone'><cite>nessy:</cite> I will add these
changes</p>
<p class='phone'><cite>raphael:</cite> section 6<br />
... improved heaps</p>
<p class='phone'><cite>erik:</cite> if we should move stuff to
appendix, we can live with that<br />
... table in 6.3 still needs heaps of input</p>
<p class='phone'><cite>raphael:</cite> MPEG-7 has track
references</p>
<p class='phone'><cite>nessy:</cite> HTML5 should be removed,
since it will do whatever we define<br />
... replace "temporal URI" with "temporal URI/Ogg" to include
the track addressing, to<br />
... "Annodex" would be correct, too, but "temporal URI" is the
best known spec out of this</p>
<p class='phone'><cite>raphael:</cite> should section 6 be
moved down in the document, so we can get specifications
first?</p>
<p class='phone'><cite>erik:</cite> I can live with that</p>
<p class='phone'><cite>raphael:</cite> I will move this section
down and do all structural changes on document directly after
the meeting before anyone else will edit again</p>
<p class='phone'><cite>jack:</cite> editorial suggestion - 6.2
is formatted completely different from 6.1<br />
... formatting of 6.1 is great - could we apply it to 6.2 ?</p>
<p class='phone'><cite>erik:</cite> will make
changes</p><a name="action04" id="action04"></a>
<p class='irc'>&lt;<cite>scribe</cite>&gt;
<strong>ACTION:</strong> erik to apply changes to section 6
[recorded in <a href=
"http://www.w3.org/2009/04/08-mediafrag-minutes.html#action04">http://www.w3.org/2009/04/08-mediafrag-minutes.html#action04</a>]</p>
<p class='irc'>&lt;<cite>trackbot</cite>&gt; Created ACTION-60
- Apply changes to section 6 [on Erik Mannens - due
2009-04-15].</p>
<p class='phone'><cite>raphael:</cite> section 7<br />
... in section 7.3 we stop talking about fragments, but talk
about sections or segments<br />
... 7.3 needs an introductory note</p>
<p class='phone'><cite>jack:</cite> I will create an
introductory note and explain that it can be either a fragment
or a query<br />
... we need some standard terminology</p>
<p class='phone'><cite>raphael:</cite> do we call it dimensions
or axis</p>
<p class='phone'>general consensus on "dimension</p>
<p class='phone'><cite>jack:</cite> do we prefer "temporal"
over "time" - "spatial" over "space" - "named" over
"name"?<br />
... track will stay track</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; +1</p>
<p class='phone'><cite>jack:</cite> all others become
"temporal", "spatial", "named"</p>
<p class='phone'><cite>nessy:</cite> +1</p>
<p class='phone'><cite>jack:</cite> I tend to use "clipping"
for temporal and "cropping" for spatial<br />
... is that a good idea or should we just use one?</p>
<p class='phone'><cite>nessy:</cite> "clipping" has a different
implication for audio ... maybe "cutting"?</p>
<p class='phone'><cite>jack:</cite> but we use "audio clip"</p>
<p class='phone'><cite>nessy:</cite> ok, fair enough</p>
<p class='phone'><cite>jack:</cite> 7.4 might need more
structure ... but how<br />
... is still very incomplete<br />
... need to continue collecting semantic issues</p>
<p class='irc'>&lt;<cite>raphael</cite>&gt; Semantic issue:
<a href=
"http://www.w3.org/2008/WebVideo/Fragments/tracker/issues/3">http://www.w3.org/2008/WebVideo/Fragments/tracker/issues/3</a></p>
<p class='phone'><cite>jack:</cite> restructure when we have a
more complete collection</p>
<p class='phone'><cite>nessy:</cite> suggestion to add a note
to the section explaining the need to contribute more semantic
issues</p>
<p class='phone'><cite>jack:</cite> ok, will do</p>
<p class='phone'><cite>raphael:</cite> section 8<br />
... Yves pointed out that 4-way contained errors</p>
<p class='phone'><cite>Yves:</cite> did not understand from
temporal URI where the resolution of time-bytes happens</p>
<p class='phone'><cite>nessy:</cite> I will go back and read
that section again and make sure the 4-way is correctly
specified</p><a name="action05" id="action05"></a>
<p class='irc'>&lt;<cite>scribe</cite>&gt;

<p class='irc'>&lt;<cite>trackbot</cite>&gt; Created ACTION-61
- And conrad to review 4-way handshake specification [on Silvia
Pfeiffer - due 2009-04-15].</p>
<p class='irc'>&lt;<cite>Yves</cite>&gt; and I note that there
is still a discussion on the ML ;)</p>
<p class='phone'><cite>raphael:</cite> should reply be 204 in
initial handshake for 4-way handshake</p>
<p class='phone'><cite>Yves:</cite> if you're sending content,
then no</p>
<p class='phone'><cite>jack:</cite> that is missing in the
specification</p>
<p class='phone'><cite>nessy:</cite> header is being sent in
first handshake</p>
<p class='phone'><cite>jack:</cite> in 2-way handshake this may
be missing, too - but it's more complicated</p>
<p class='phone'><cite>raphael:</cite> silvia &amp; conrad -
please make changes in wiki ... I will then sync the wiki with
the WD myself</p>
<p class='phone'><cite>nessy:</cite> ok</p>
