Hi all,

below are our minutes again, with links to the issue numbers to make 
tracking easier. Please look at the proposals to drop issues / merge 
issues / create new issues, and discuss in separate, issue-specific 
threads until next meeting.

Note also that we have some use cases / requirements we did not discuss 
on the call yesterday, also one more since then (6113). Please also look 
at these and discuss via mail. It would be good if we could come so far 
until next week to have a vote "should be taken into account 'yes' / 'no'.

*6084* <http://www.w3.org/Bugs/Public/show_bug.cgi?id=6084> Use case 
"multimedia adaptation"

*6085* <http://www.w3.org/Bugs/Public/show_bug.cgi?id=6085> Use case

"Allowing for a simple API, abstraction in the ontology, and a clear 
mediation inbetween"

Veronique had sent information on IPTC, and we will not keep this

<VeroniqueM> I could also participate in editing, but I have very
few experience with this...

tobias: I can edit later

daniel: we will be a team

felix: every editor will edit each deliverable

<hmiao> i would like to join editing, though i've little experience.


[20] http://www.w3.org/2008/01/media-annotations-wg.html

<spark3> Hui and tobias are volunteers for editing team as of today

Open issues

<raphael> There is an open questionnaire regarding the formats in
scope and out of scope, could we keep it open one more week ?

<hmiao> anyone mension the youtube like video yet ?

<hmiao> it'll be an important format for our application

daniel: propose that we go through the issues until next
teleconference via mail, and try to wrap them up during that call,
and work on the editors draft just after that

<VeroniqueM> would it make sense to link the use cases with
requirements lists more specifically?

<spark3> Raphael, yes, we will open for all of open issue until next

<scribe> ACTION: Felix to extend "formats ... scope" for one more
week [recorded in

<trackbot> Created ACTION-5 - Extend \"formats ... scope\" for one
more week [on Felix Sasaki - due 2008-09-30].

<VeroniqueM> this might hep us getting a list of requirements?

<VeroniqueM> maybe we can make a short list of the use cases, just
by their names?

Use case "Services by using an unified media annotation", issue 6064

<VeroniqueM> yes

<wbailer> yes

<davy> yes

<erik> yes

Use case "Video on IPTV", issue 6065 - should that be merged into 
another use

<VeroniqueM> yes

<spark3> yes

<davy> yes

<wbailer> yes, merge with services

<erik> yes

<tobiasbuerger> yes

Requirement "Covering variations across locales", issue 6066

<spark3> it's requirements, yes

<wbailer> yes, it's maybe related to adaptation use case?

<VeroniqueM> or to interoperability?

Use case "Audiovisual archive as a Cultural Heritage institution", issue 

<spark3> yes

<wbailer> yes, as mentioned on the list it might be broad and could
be more concrete

<wbailer> agree

veronique: well, it was more a general view than a specific usecase,
but can be splitted into searching and interoperability

<spark3> agree

<davy> yes

<tobiasbuerger> yes

<erik> yes

<VeroniqueM> yes

Use case "Metadata to help promoting safe environments", issue 6068

<VeroniqueM> can be related to personalisation, to some extent?

Felix: should it be a separate use case? Or

<wbailer> agree to relate it to other uc

Felix: be related to something else

<tobiasbuerger> we could also merge it with the services use case...

<erik> agree to relate it

Use case "Multi media and semantic web technologies", issue 6069

<tobiasbuerger> This is too broad I guess and not meant as a use
case. Yes - please drop it

drop this since it is too broad?

<davy> agree

<VeroniqueM> agreed

<wbailer> agree

<spark3> agree

<erik> agree

<raphael> agree

Use case "Photo", issue 6077 - should we take this into account?

<raphael> Does the charter talk only about videos ?

<VeroniqueM> has this not be covered by the XG?

<spark3> isn't it related to Multimedia Annotation XG ?

<VeroniqueM> Image annotation I mean


[22] http://www.w3.org/2008/01/media-annotations-wg.html

<raphael> No, the role of the XG was not to promote a particular
schema or ontology for describing media

<wbailer> yes, but somehow it'orthogonal: media types vs application
like searc etc

"This Group is chartered to provide a simple ontology to support
cross-community data integration of information related to media
objects on the Web, as well as an API to access the information."

(from the charter)

<raphael> ... but rather to investigate how SW technologies help to
build bridges between exixting formats and standards

daniel: our homepage talks about video, audio and images

<spark3> Video/Audio/Images

<raphael> ... so my conclusion is, there is still a lot to do to
make the DC for photos, or videos

<tobiasbuerger> +1, Raphael. Agree.

<erik> +1

Use case "music", issue 6078 - should we take this into account?

daniel: not sure

<raphael> Same conclusion, the pseudo-formalization of the ID3 tags
using the Music Ontology is interesting and might be a good start up

raphael: "same conclusion" means: valid use case?

<VeroniqueM> not sure either, lots of very specific issues would
then be taken into account

<VeroniqueM> ok to Raphael

<wbailer> but music ontology is quite specific, we should stay on a
more generic level

<raphael> Yes, valid use case, I think ... in the sense that your
title property would be likely to be used for a title of a movie or
a song

<raphael> ... and a link to the ID3 title is a good thing, etc.

<raphael> agree for the music ontology, I'm talking about reusing
some elements ... and link to some others

Felix: sounds like a valid use case but on a very general level

<wbailer> providing means for linking seems to be a good idea

Use case "News", issue 6079

<erik> yes

<tobiasbuerger> yes

<raphael> I see the outcome of this group as a core schema, with a
lot of open windows to standards, with explicit semantics

<VeroniqueM> that's a very complex and very interesting use case!
Vote for yes

<raphael> News: not in the state that it is described in the XG
document .. but yes in the general sense

<wbailer> yes, i see the same thing as for music: avoid getting too

<spark3> yes

Use case "Tagging", 6080

<VeroniqueM> in what sense?

<spark3> tagging for what ?

<VeroniqueM> as values for a schema?

<VeroniqueM> or instead of it?

<tobiasbuerger> what it was about: "The tagging use case which
tackles the problem of interoperability and portability of tagging
systems and personal tags."

<raphael> Goal of the XG was to allow reusing a personomy between
various platforms

<raphael> ... example: you use the same flickr tags on delicious

<wbailer> merge it with interop?

<raphael> ... you own your tags, defined in SKOS, and you can search

<VeroniqueM> in that case, makes sense

<VeroniqueM> if you define them

<raphael> ... each tags has a global URI and is formally defined

Felix: maybe we will not be able to solve that interoperabiltiy
problem, only on a very high level of the ontology, and leave the
rest to other fora

Use case "semantic media analysis", 6081

Felix: too general - close that?

<raphael> agree

<spark3> agree

<davy> agree

<tobiasbuerger> I guess we should take some aspects into accout...

<wbailer> agree, analysis is done for search, adaptation ,...

<tobiasbuerger> ...like links between modalities

<VeroniqueM> like semiotic relations between speech and image in a

tobias: how text can support the analsys of media. This use case is
about references between text and parts of the image

felix: do you think the relations should be typed and part of the

tobias: yes

felix: let's discuss this via mail

Use case "algorithm representation", 6082

<wbailer> drop

<tobiasbuerger> drop

felix: out of scope - drop it?

<VeroniqueM> yes

<davy> yes

<raphael> agree to drop it

<erik> yes

wrap up

Daniel: please check


daniel: and make discussion on the list

<raphael> is next week telecon changing hour ?

yes, see schedule at

<raphael> ok, it has been approved ?

<spark3> 21 UTC

<raphael> ok, thanks, I can make it :-)


tobias: can I participate in TPAC f2f via phone?

Felix: yes, we have a bridge for both days
