RDF Task Force

<scribe> scribe: florian

Tobias: Martin and i have updated the wiki page entry - Veronique and Pierre-Antoine did?nt contribute yet

http://www.w3.org/2008/WebVideo/Annotations/wiki/Ontology_Implementation

Tobias: we could make a webimplementation using e.g., Dublin Core - may not cover everything

Jean-Pierre: why do you want to use DC etc.? Don?t have the MA namespace
... you have to distinguish between classes and the implementation

Tobias: we should define first the concepts and map these to other ontologies

Tobias (explaining Jean-Pierre point): we must first define classes that we need, than look into the implementation

Tobias: let?s go through the mentioned classes in the wiki entry if they are complete
... better if they cover our needs
... first we need a class for resource
... why program?

Jean-Pierre: it?s just an illustration
... for me resource is ok

Joakim: we should name it MediaResource

Tobias is going through the set of core properties and derives classes together with the group

List of needed classes: 1. MediaResource 2. Creator 3. Cotributor 4. Publisher 5. Location 6. Collection 7. MediaFragment 8. Concepts

Tobias: i do not know, if we need to distinguish between 2., 3. and 4.

Jean-Pierre: of course you can merge them, but than you have to define rules etc.

Werner: here we go beyond the attributes we have defined
... the main question is how far we want to go in defining the attributes of these classes

<scribe> scribe: florian

RESOLUTION: we take these classes defined in the 7th MAWG F2F (1. - 8.)

Tobias: we might add subclasses to 1. if we want
... the next step is to define the properties

The group goes through the list and chooses, whether properties are data or object properties

identifier data property?

yes

title data property? - yes

language data property? -yes

locator - dp

contributor - op

creator - op

createDate dp

DP ma:identifier

DP ma:title

DP ma:language

DP ma:locator

OP ma:contributor

OP ma:creator

DP ma:createDate

OP ma:location

DP ma:description

DP ma:keyword

OP ma:genre

OP ma:rating

OP ma:relation

OP ma:collection

DP ma:copyright

DP ma:policy

OP ma:publisher

OP ma:targetAudience

OP ma:fragments

OP ma:namedFragments

DP ma:frameSize

DP ma:compression

DP ma:duration

DP ma:format

DP ma:samplingrate

DP ma:framerate

DP ma:bitrate

DP ma:numTracks

dp == data property, op == object property

Tobias will make a ontology proposal to have a basis to discuss.

<scribe> ACTION: tobiasb to come up with an ontology proposal on the basis of the Task Force Meeting in the 7th MAWG F2F [recorded in http://www.w3.org/2010/04/27-mediaann-minutes.html#action13]
