[Tracker] Ontology addition for media files

[Lionel Landwerlin <lionel g landwerlin linux intel com>]

Hi all,

I have this use case where a multimedia application would like to
restart an already played stream at the last played position.
I'm also interested in having the play count and the last played
date/time.
At the moment there is no such property to store that kind of
information on media files.

To test my use case in the application I quickly added the following
properties in the tracker ontology (but I know it's not the right
place) :

tracker:lastPlayPosition a rdf:Property ;
        nrl:maxCardinality 1 ;
        rdfs:domain nfo:Media ;
        rdfs:range xsd:integer .

tracker:lastPlayDate a rdf:Property ;
        nrl:maxCardinality 1 ;
        rdfs:domain nfo:Media ;
        rdfs:range xsd:dateTime .

tracker:playCount a rdf:Property ;
        nrl:maxCardinality 1 ;
        rdfs:domain nfo:Media ;
        rdfs:range xsd:integer .

Now that this seems to work, I would like to see that added in Tracker
upstream.

So where should these properties go ?

nfo ? nmm ?

Thanks for your insights.
