[edit] Proposal Revision 1.14
As suggested in the mailing list: related to following all versions and mo:Release instances of an abstract musical work (mo:MusicalWork, abstract song or album) and as a continuum of proposal revision 13 (also discussed in the mailing list). With the extensions described below it is probably better to map services like discogs to MO and to enable queries like "Show me all versions that are produced to that (abstract) song." - the result will be all different recordings and re-recordings of a song. Or "Show me all releases of that song." - the result will a list of mo:Release instances of maybe different mo:Medium types, released in different countries at different times. The following graphic should illustrate the changes:
More extensions are:
- mo:Playlist (drawn in several papers, but not implement yet), which should also handle things like song sequences - so when shuffle mode is enable it do not destroy that specific sequence while mixing the playlist
- mo:Mood as a hook for a mood ontology/taxonomy
[edit] Recording Session concept
[edit] Description
To keep track of a specific mo:RecordingSession event of e.g. a specific mo:MusicGroup, which is in general related to an abstract album (mo:MusicalWork). The property mo:recording (currently event:sub_event) could bind all related single mo:Recording instances of this mo:RecordingSession event. mo:produced_signal_group is the product of that mo:RecordingSession event with all produced mo:Signal instances of the mo:Recording instances.

As a result of a mo:RecordingSession instance the mo:SignalGroup concept knows all produces mo:Signal instances (mo:signal) of it. It can also have a short cut to the related abstract album (mo:MusicalWork instance; currently with frbr:subject) to skip the workflow part of the mo:RecordingSession.

[edit] Release event concept
[edit] Description
The mo:ReleaseEvent concept takes a mo:SignalGroup instance (mo:released_signal; as a product of a mo:RecordingSession event or as a separate composition of single mo:Signal instances of several mo:SignalGroup instances from different mo:RecordingSession events) and produces on or more mo:Release instance(s) (each of a specific mo:Medium, which are releated to its mo:ReleaseEvent instance over mo:release_event) that is/are released in a specific country at a specific time. The specific mo:ReleaseEvent instance should be related to a mo:Label (mo:label).

[edit] Release concept
[edit] Description
A mo:Release instance is a the result of a mo:ReleaseEvent instance. So it contains on or more mo:Record instance(s) (mo:record) of a specific medium. This package should be related with properties like cover-art, libretto etc. (not implemented yet). As a mo:Release is an official release it has also a catalogue number (mo:catalogue_number).

[edit] Track concept
[edit] Description
An extension to the mo:Track concept to handle both related mo:Signal instances - the mo:Signal instance of the copy (mo:track_signal, currently mo:encodes) and the original mo:Signal instance (mo:originated_signal, currently mo:publication_of and its inverse property mo:published_as), which is related to the specific mo:Recording instance. Of course, these properties exist in a certain kind, but maybe it is easier to access them in this way (see this part of the email discussion).
=> Note: It is already possible to model these relations somehow with the Music Ontology (see descriptions and hints). Hence, there might no need to introduce these new properties.
:signal1 mo:published_as :track1 . :track1 mo:available_as <test.mp3> . <test.mp3> mo:encodes :signal2 . :signal2 is the deteriorated signal, and :signal1 is the original one.

[edit] Counter property
[edit] Description
To keep track of the overall size of the instances of mo:Record and mo:Release. For a mo:Record instance the counter is a track counter (currently mo:track_count) and for a mo:Release instance the counter is a record counter (currently mo:record_count). Maybe the specific counters can also be derived from this property.
