Todo list

From Music Ontology Wiki

This is the list of things to do for the development of the Music Ontology.

Please add items if needed.

Contents 1 Music Ontology 2 Activity 3 Membership 4 Done 4.1 Others

Music Ontology

• mo:Mood as hook for a mood ontology/taxonomy => see ao:mood as super property (also ao:genre as super property of mo:genre => done)
• associating mo:Record, mo:Track (mo:MusicalManifestation) to its carrier medium (mo:Medium (mo:MusicalItem)) => possible solutions:
  • The Media Format Ontology for describing media types as sub classes of mo:Medium (that means on the "item level")
  • Media Types as SKOS scheme for describing media types as sub classes of dcterms:MediaTypes (or sub classes of dcterms:MediaTypes) on the "manifestation level" by using the property mo:media_type
• broaden the domain of mo:tempo to sim:Association and/or mo:genre to describe associations and/or genres (cf. ex:tempo in the UMIRL example)
• add an inverse property for mo:membership (or change its domain and range); see also the original mo:Membership proposal
• align mo:membership (or its inverse property) and mo:group to event:agent (sub property relation)
• mo:producer should be shifted to the expression level, since a producer is more included into the production process, e.g., recordings, of a musical work, or?

Activity

• Create a mo:activity property and a mo:Activity class (subclass of event:Event) to model activity timeframes, e.g.

ex:The_Specials

mo:activity [
  a mo:Activity ;
  ev:time [
    tl:start "1977" ;
    tl:end "1984" ;
  ]
]

Membership

• Create a mo:artist property to link a mo:Membership to its artist(s) - in addition to the current mo:group property, e.g.

ex:the_beatles

mo:membership [
  a mo:Membership ;
  mo:artist ex:georges_harrison .
]

Done

• Add mo:origin for an artist
• Add activity_start and end for an artist
• Move mo:label to mo:Release instead of mo:ReleaseEvent (? - see related discussion)
• Add mo:Signal (and mo:Track?) to the domain of mo:bpm, mo:key, mo:tempo (?)
• Just a very minor thing: DAT label is wrong. It is Digital Audio Tape (and not Data Audio Tape).
• mo:lyrics => should be something to associate a mo:MusicalWork with mo:Lyrics, or?
• mo:headliner as subPropertyOf mo:performer (see also MO Proposal 2.1 )
• change domain mo:instrument / mo:label to include mo:MusicArtist
• add mo:duration_ms - domain mo:Signal, mo:Track; range xsd:int, xsd:float
• add mo:Label to domain of mo:musicbrainz_guid as labels have MBIDs
• bring back mo:duration - domain mo:Signal, mo:Track; range xsd:duration or empty?
• Change mo:genre domain to include mo:Track, mo:Record, mo:Release, mo:MusicalItem (?); remove probably isSubPropertyOf event:factor relation
• Add 78 medium (requested by Chris Cannam)
• Look at added properties in moplus
• mo:similar_to domain/range expansion - add mo:MusicArtist/Group/SoloArtist at least and mo:MusicalManifestation as per the group mailing list thread
• mo:encoded_as (or something inverse of mo:encodes)
• Links to RDF specification from HTML specification
• mo:iswc on mo:MusicalWork
• mo:Transcription (new event)
• Sort out ShepardLevel1Issues mentioned on #musicontology (more comments: ZaziLevel1Comments and mailing list thread)
• Implement changes suggested by Antoine Zimmermann here
• Implement group membership model proposed by Simon Reinhardt here
• Implement identification properties proposed by Simon Reinhardt here
• Number of discs
• Modeling of lyrics that are core part of musical works
• mo:text (used in Jamendo)
• release events
• mo:meter
• Clean up double typing
• Sort out level 1, publish diagrams, reduce useless parts of the main spec website
• mo:genre applied to foaf:Agent
• Inverse labels instead of inverse properties
• More functional properties (in the workflow, there are a lot...)
• Podcast as musical manifestation
• Linking artist to usual instrument
• mo/foaf:InfoService + mo/foaf:info_service (FOAF wiki) => Info Service Ontology
• MO Listening Ontology:
  • ListenEvent (to replace the ScrobbleEvent in the last-fm ontology) => currently ListenEvent is removed from MO => co:ScrobbleEvent as general purpose scrobbling event for counting an activity (see concrete example)
  • implement mo:Playlist as drawn in several papers (should also include things like song sequences etc. or the model of a smart playlist) => pbo:Playlist as general media playlist (bibo:Document, frbr:Endeavour based), example
  • mo:play_count, mo:skip_count to keep track of the listening behaviour of tracks => pbo:PlayBackCounter and pbo:SkipCounter, example

Others

• Link the event ontology to ABC
• Update audio feature ontology (holding some speech-related things)
  • It should cover Vamp features, at least
  • af:time_signature (perhaps in MO?)
