Map to BBC PO and MO

[moustaki]

Just wondering whether we could map the resulting schema to PO and MO. A couple of mappings that come to mind:

BBC PO (http://www.bbc.co.uk/ontologies/programmes):

schema:TVEpisode owl:equivalentClass po:Episode ; rdfs:subClassOf po:Programme .
schema:TVSeason owl:equivalentClass po:Series ; rdfs:subClassOf po:Programme .
schema:TVSeries owl:equivalentClass po:Brand ; rdfs:subClassOf po:Programme .
schema:episodes shouldn't be using a list as a range - I suggest using po:episode there.
schema:episodeNumber owl:equivalentProperty po:position .
schema:seasonNumber owl:equivalentProperty po:position .
schema:seasons owl:equivalentProperty po:series .

MO (http://musicontology.com):
schema:AudioObject owl:equivalentClass mo:AudioFile.
schema:MusicAlbum owl:equivalentClass mo:Record.
schema:MusicRecording owl:equivalentClass mo:Track. (not sure about this one - the schema.org definition is ambiguous to say the least!)
schema:Event owl:equivalentClass event:Event .
schema:Festival owl:equivalentClass mo:Festival .
schema:MusicEvent owl:equivalentClass mo:Performance .

Another note - I am unsure how Duration is supposed to be used, as it seems to map straight to a datatype.

Yves, these are great. Don't worry too much about precision—schema.org is quite fuzzy, and intentionally so I believe, so our mappings can be fuzzy too. Do you consider these complete or can you come up with more?

Just a few comments and additions to the MO mapping:

1. re schema:MusicRecording - I guess, it really depends here on what is represented on the related, whether it is a mo:Signal (expression level) or mo:Track (manifestation level); I would exclude the item level for now, since one can relate the concrete encoding via the 'encoding' relation (which is of the schema:MediaObject)
2. re. schema:MusicAlbum - I would tend to suggest mo:Release instead since a mo:Release can contain several mo:Record instances, e.g., a music album that consists of two CDs; however, the problem there is that schema:MusicRecording instances can be related to schema:MusicAlbum which would then be equivalent to mo:Record instances - to sum up the do not really deal with releases that consists of multiple "records"
3. schema:MusicGroup owl:equivalentClass mo:MusicGroup
4. schema:MusicPlaylist owl:subClassOf pbo:Playlist (pbo: http://purl.org/ontology/pbo/core#)

i think we can even map more properties to MO, but this requires a bit more time for investigation.
