<p class='phone'><cite>doug:</cite> make sure to look at right
version<br />
... previous comment still holds for the current version<br />
... don't think that browser vendors will implement all the 32
interfaces in the spec</p>
<p class='irc'><<cite>tmichel</cite>> LC comment from
Doug</p>
<p class='irc'><<cite>tmichel</cite>> <a href=

<p class='phone'><cite>doug:</cite> approach is very java-like,
very verbose, strongly typed<br />
... same solution as proposed at last tpac an even before group
started: only 1 or 2 methods only for getting metadata<br />
... generic methods instead of typed interfaces</p>
<p class='irc'><<cite>tmichel</cite>> should have only
one ot two methods allowing to get the metadata generecly</p>
<p class='phone'><cite>doug:</cite> there is generic
getProperty, but different interfaces for return types</p>
<p class='irc'><<cite>tmichel</cite>> doug: what is the
goal of all these interfaces ?</p>
<p class='irc'><<cite>tmichel</cite>> Doug: I was
confused, with earlier draft. But now it seems fine.</p>
<p class='phone'><cite>doug:</cite> specific return types are
not necessary<br />
... to get data in a generic way will not work with strongly
typed return types<br />
... it's more java and not usual for javascript developers used
to json structures<br />
... could be name value pairs<br />
... should not be described as interfaces<br />
... generic json style object should be the goal<br />
... dicussion on filtering results at last tpac<br />
... eg getting all titles, filter for subtitles, episode titles
etc<br />
... or filter for certain format<br />
... not sure how to do that with a generic array<br />
... document states its for both client and server side
use<br />
... not clear how it could be used on a server</p>
<p class='phone'><cite>joakim:</cite> api exposed as web
service, to be called from client</p>
<p class='phone'><cite>doug:</cite> shared ontology is
useful<br />
... not sure if designing for both client and server is good
approach<br />
... focus on client<br />
... metadata for media file can be remote<br />
... important to clarify what is meant by the interfaces<br />
... should clarify that people are not expected to implemented
multiple different interfaces</p>
<p class='phone'><cite>joakim:</cite> there are 3
questions:</p>
<p class='phone'>1. what is meant by interfaces</p>
<p class='phone'>2. less strong typing of return types</p>
<p class='phone'>3. filtering results by subproperties</p>
<p class='phone'><cite>doug:</cite> if you do not talk about
interfaces, the question of whether all need to be implemented
disappears<br />
... if application supports ontology, it should be possible to
retrieve all the values<br />
... are there properties that there are more problematic than
others?</p>
<p class='phone'><cite>joakim:</cite> here is an example for
title in 3.5.2.1<br />
... returning a specific subtype of title</p>
<p class='phone'><cite>doug:</cite> json format as return
format would make things easier to understand<br />
... need to look more closely to this</p>
<p class='phone'><cite>joakim:</cite> could you propose an
example?</p>
<p class='phone'><cite>doug:</cite> json looks ok, but maybe
not with a more complex example<br />
... makes more sense to have a json style repsonse format<br />
... plan to talk to Cameron McCormack about whether is the
correct use of webidl for this purpose<br />
... scenario: mp3 with album title, song title, annotations in
id3<br />
... plus annotations in xmp with the 2 titles<br />
... expect to get 4 titles, 2 from id3, 2 from xmp<br />
... expect to be able to filter to just get the xmp<br />
... in addition, get creation date of metadata and author of
metadata<br />
... using same set of properties for meta-metadata seems to be
solution</p>
<p class='phone'>needs to be described in the document</p>
<p class='phone'><cite>doug:</cite> each piece has to contain
where it comes from<br />
... either on the high-level structure or as a nested
structure<br />
... on high-level, it would be useful to all titles and
authors<br />
... but to filter by annotation, and not go down to specific
properties and then filter<br />
... meta-metadata should be part of return data<br />
... rather than overloading getProperty, return values first
and filter results<br />
... append filters to narrow results</p>
<p class='irc'><<cite>joakim</cite>> I was thrown out
from zakim</p>
<p class='phone'><cite>doug:</cite> will draw up a few
scenarios, and put together what I expect the api to return</p>
<p class='phone'><cite>joakim:</cite> people at sony ericsson
were interested in having provenance of metadata</p>
<p class='phone'><cite>doug:</cite> would like to talk to
browser vendors more deeply, not sure if possible in time<br />
... currently not sure that all common use case are covered by
the api<br />
... will draw up scenario and wg to decide whether its covered
by the spec</p>
<p class='phone'><cite>thierry:</cite> set up specific telecon
with api doc editors and doug at a time more convenient for
doug<br />
... possible time tuesday 13:00 utc (15:00 cest)</p>
<p class='phone'><cite>joakim:</cite> anything urgent about LC
status?</p>
<p class='phone'><cite>thierry:</cite> thought about scheduling
2nd LC, in order to manage before tpac<br />
... seems very difficult to achieve<br />
... goal should be to finalise docs a tpac</p>
<p class='irc'><<cite>daniel</cite>> I think we may can
not catch up the proposed schedule. There are still so many
open issues...</p>
<p class='phone'><cite>thierry:</cite> to avoid 3rd LC<br />
... before tpac we should have a good idea what has already
implemented from lc comments<br />
... some commenters want to see editors draft</p>
