New use case "Digital imaging lifecycle"





ruben: jpeg in process of defining metadata for digital image
... specific type of search/retrieval uc

felix: keep use case and discuss in future call

<fsasaki> or via mail

New use case "life log"



<cgi-irc> maybe it can be an interesting use case for checking how
the interoperability across media can be achieved

<fsasaki> veronique = cgi-irc

<pchampin> +1 veronique

veronique: consider in second stage of ontology dvelopment

XMP review

<fsasaki> [28]http://www.w3.org/2008/WebVideo/Annotations/wiki/XMP

[28] http://www.w3.org/2008/WebVideo/Annotations/wiki/XMP


[29] http://www.w3.org/2008/WebVideo/Annotations/wiki/XMP#Dublin_Core_schema

thierry: dublin core: everything could be adopted

felix: some fields (eg data) quite general, might conflict with
fields from other standards

werner: +1, I think for most dc fields we need to specify how we use

ruben: granularity of fields (eg name, more structured eg in mpeg-7)

david: string is general, everything else might cause eg
internationalisation problems

<dsinger> it may be solved, but it can be a tarpit

goal is to keep simple

veronique: pointing to vocbulary (eg artist names)

<pchampin> wouldn't that be interesting, nevertheless, to allow the
URI of another resource (possibly defined elswhere), insread of a
plain string?

felix: need to decide whether internationalistation of names is an
issue or we just map to simple strings

<dsinger> it's intriguing to think that anything can be a value or a

<dsinger> but what happens if I say "my name is" "URI to jpeg image"

<dsinger> ?

<pchampin> I was rather suggesting "the creator is (string|URI)"

david: uri issues brings us back to foaf

<pchampin> I'm not suggesting that we should embed the descrition of
that URI...

<dsinger> friend of a friend?


[30] http://www.foaf-project.org/

<dsinger> you mean? <[31]http://xmlns.com/foaf/0.1/>

[31] http://xmlns.com/foaf/0.1/%3E

<frank> A string is not less ambigious than a URI (I could write
name = sjdhfqflf

<pchampin> I would say a string is *much more* ambiguous

joakim: foaf is used in imdb

<pchampin> But we can not assume every person to have a URI with
appropriate FOAF properties

<dsinger> in terms of presentation, it's very clear; a URI
("gopher:" ?) is much less obviously presentable

<js> foaf is used by linked movie database

felix: string may be meaningful or not, additional uri (need to
ensure that uri points to suitable resource)

<rtous> also a problem with "address" field

XMP Basic schema


[32] http://www.w3.org/2008/WebVideo/Annotations/wiki/XMP#XMP_Basic_schema

felix: going through elements

XMP Rights Management schema



dave: even simple copyright can become complex (eg composition of
... simple copyright cannot be ignored

felix: does that require to include properties into ontology

dave: simple copyright, global to media

<frank> I thought we had decided in the last f2f meeting that we
simply go for one slot

joakim: dynamic temporal metadata support (for real time apps)

<dsinger> I am tempted to say that ALL metadata is temporal, but the
first version only allows you to ask "right now" what is...?

<dsinger> which covers a radio station where it varies by song...

XMP Media Management schema



veronique: 3 levels: content - realisation -instance
... still to be decided whether 3 or 1 level

<dsinger> yes, use cases are essential: we'll never decide what we
want if we don't know what we want it to be useful for

<rtous> Functional Requirements for Bibliographic Records (FRBR) :

[35] http://en.wikipedia.org/wiki/FRBR

ruben: different levels could simplify things (e.g. content
description such as title vs tech metadata like encoding)

+1 ruben

<cgi-irc> we can also check out how many models go for 3 levels and
how many go for 1

<cgi-irc> VRA has also 3 levels

<js> mpeg-7 has two

<pchampin> I'm still not sure there should be a *constant* level of

<cgi-irc> two is good enough

<dsinger> what are the 3 levels? (sorry...)

content - realisation -instance

<dsinger> thx

<pchampin> what about the photo of a painting?

felix: volunteers for looking at how standards handle this issue?

<pchampin> or a movie making of?

<rtous> I can do that

<scribe> ACTION: ruben to survey how other standards handle the
issue of levels of description [recorded in

<trackbot> Sorry, couldn't find user - ruben

<scribe> ACTION: rtous to survey how other standards handle the
issue of levels of description [recorded in

<dsinger> well, basically "content: beethoiven's 5th; realisation:
berlin phil, 1962; instance: cassette tape from DG 1964"???

<tobiasbuerger> who do these three levels relate to the levels
defined in FRBR (work-expression-manifestion-item)? content:==work,
expression==realisation, manifestation==instance; item is not

<js> you can also look at the music ontology who has adopted the

<tobiasbuerger> yes, the music ontology adapted FRBR I guess

XMP Basic Job Ticket schema



XMP Paged-text schema



<tobiasbuerger> I guess we do not need it in our current use cases

<tobiasbuerger> (I meant the basic job ticket information)

XMP Dynamic Media schema



joakim: many detailed technical aspects included

<fsasaki> xmpDM:logComment User’s log comments.

veronique: does this refer to tagging?

felix: little information in xmp spec

veronique: slot for tags needed - could this field by used?

all to look at xmp reviews, discussion continues next week

Draft for Use cases and requirements document

veronique: more ideas/comments about general structure should be
sent to list

<fsasaki> ACTION: Felix to write a mail about the general structure
of the use cases / req document [recorded in

<trackbot> Created ACTION-37 - Write a mail about the general
structure of the use cases / req document [on Felix Sasaki - due

API/Ontology draft proposal

all to review and comment

felix: formal definition of ontology, complexity of api, etc

<dsinger> thx, bye!

<tobiasbuerger> bye

<rtous> bye

<js> bye

<frank> bye
