<p class='irc'><<cite>raphael</cite>> Werner suggests we
don't use the term "Mask"</p>
<p class='irc'><<cite>davy</cite>> continuous view?</p>
<p class='irc'><<cite>erik</cite>> "continous part"?</p>
<p class='irc'><<cite>raphael</cite>> Replace "mask" by a
"single segment"</p>
<p class='phone'>jackjansen, just add a statement that we don't
want holes</p>
<p class='irc'><<cite>raphael</cite>> Jack: we don't want
holes</p>
<p class='phone'><cite>raphael:</cite> section 3.1 figure
explains context, but the last row "example image track"
illustrates that we can take a blob of an image, but the text
doesn't consider this</p>
<p class='phone'>raphael, case, eg. spatial regions of
images</p>
<p class='phone'>phillip suggested we specify that we also
support spatial ranges</p>
<p class='phone'><cite>jack:</cite> what is the difference
(from our point of view) between text and image track?</p>
<p class='phone'>i think the overlapping content is the main
thing</p>
<p class='phone'>so for temporal addressing there can be
multiple text elements which match a temporal region</p>
<p class='phone'><cite>jack:</cite> for this draft perhaps we
should only specify audio+video</p>
<p class='phone'>and chasing dependencies of previous text
elements (ie. working out which are active now) can be more
difficult than eg. video keyframes</p>
<p class='phone'><cite>raphael:</cite> we should publish,
including these minor changes</p>
<p class='phone'><cite>jack:</cite> editorial note by silvia is
a question to the reader<br />
... editorial note by dave singer, needs to be addressed (sec
3.12)?</p>
<p class='phone'>"The fallback plan needs to be clarified. We
must be able to handle the way the # is already used, e.g. in
YouTube, without breaking what is already working."</p>
<p class='phone'><cite>raphael:</cite> the wg. has discussed
that we need to be backwards-compatible with existing
implementations as much as possible</p>
<p class='phone'>eg. youtube syntax, and we are still
discussing what the behaviour should be</p>
<p class='phone'>so is the vague phrasing of compatibility with
"widely implemented solutions" enough?</p>
<p class='phone'><cite>raphael:</cite> we have already
discussed that eg. the youtube way could be a different syntax
we specify, with explicity hms</p>
<p class='phone'><cite>jack:</cite> ok then we should add a
sentence about that, and a note to suggest that parsers
recognize foreign syntax and stay away from it<br />
... so if we draft a paragraph and send it to dave, see what he
thinks</p>
<p class='phone'><cite>raphael:</cite> ok, but also that is not
blocking the publication of documents</p>

<p class='phone'><cite>raphael:</cite> no progress on 117 and
112, pending comments by silvia</p>
<p class='irc'><<cite>raphael</cite>> Raphael: suggest to
postpone decision on publishing this doc to next week</p>
<p class='phone'><cite>Raphael:</cite> after 117 and 112 are
complete, we can think about publishing the documents, as they
don't currently reflect the progress we have made</p>

<p class='phone'>all actions on test cases are pending</p>
<p class='phone'>jackjansen, please notify the mailing list
when spec changes are made</p>

commit emails etc. etc.</p>
<p class='irc'><<cite>nessy</cite>> conrad: yes, but we
won't have access to the cvs management box, I don't hink</p>
<p class='irc'><<cite>nessy</cite>> Yves would know if
that was possible</p>
<p class='irc'><<cite>jackjansen</cite>> I second
silvia's proposal</p>
<p class='phone'>usually there is a separate mailing list for
cvs-commits, and a post-hook added to cvs to mail commit
details to that list</p>

like that</p><a name="action01" id="action01"></a>
