<p class='irc'><<cite>raphael</cite>> Raphael:
|
|
summarizing the long thread and discussion about
|
|
extensibility</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> ... and summarizing
|
|
the position of philip</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> Jack: the only
|
|
thing we should say is: if we partially understand a media
|
|
fragment, should we accept or ignore ?</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> ... this is one
|
|
line in the spec</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> ... we should
|
|
accept what is acceptable</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> ... and in
|
|
particular if a media fragment URI can have things we don't
|
|
understand</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> ... and personally
|
|
I don't care about the grammar</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> Yves: we should be
|
|
very caution with extension</p>
|
|
|
|
<p class='phone'><cite>Yves:</cite> we should be careful with
|
|
extensions</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> ... e.g. the ref
|
|
redefines an existing dimension</p>
|
|
|
|
<p class='phone'><cite>Jack:</cite> explains we could use an
|
|
attribute to control strict or loose parsing</p>
|
|
|
|
<p class='phone'><cite>All:</cite> think this is ugly</p>
|
|
|
|
<p class='irc'><<cite>Yves</cite>> :)</p>
|
|
|
|
<p class='phone'><cite>Jack:</cite> suggestion: we mandate the
|
|
chair to decide something</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> Jack: I have no
|
|
strong feeling either way</p>
|
|
|
|
<p class='phone'><cite>Jack:</cite> I do think (and so does
|
|
Davy) that if we recognize the attribute name then the value
|
|
must adhere to our syntax</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> #t=banana ... means
|
|
parsing stops</p>
|
|
|
|
<p class='irc'><<cite>davy</cite>> #t=10&t=20 ...
|
|
means parsing stops?</p>
|
|
|
|
<p class='irc'><<cite>Yves</cite>> well if you always
|
|
ignore what you don't understand #t=banana&xywh=10,10,20,20
|
|
should be xywh=10,10,20,20</p>
|
|
|
|
<p class='irc'><<cite>davy</cite>> I disagree</p>
|
|
|
|
<p class='phone'>That woulnd mean that t=1o&xywh=1,2,3,4
|
|
would parse</p>
|
|
|
|
<p class='irc'><<cite>Yves</cite>> this is what is
|
|
consistent with 'ignoring what you don't understand'</p>
|
|
|
|
<p class='irc'><<cite>Yves</cite>> we have t=npt:120,
|
|
what happens if we have t=<mytimeunit>:120 ?</p>
|
|
|
|
<p class='irc'><<cite>Yves</cite>> we can have
|
|
extensionaxis = extensionname = extensionvalue</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> Jack: we should not
|
|
try to encode in a grammar what we will not understand</p>
|
|
|
|
<p class='irc'><<cite>Yves</cite>> but jack, encoding
|
|
extension points is a good thing to do</p>
|
|
|
|
<p class='phone'><cite>Yves:</cite> either we do nothing about
|
|
extension or do it correct, with extensionaxis in the
|
|
grammar<br />
|
|
... we could check what existing implementations do</p>
|
|
|
|
<p class='phone'><cite>Raphael:</cite> they are waiting for us
|
|
to specify correct behaviour<br />
|
|
... time to adjourn</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> Jack: I suggest the
|
|
chairs put a deadline and take a decision on this issue</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> Raphael: I agree, I
|
|
will have a discussion with Erik</p>
