This page is for discussing mapping of Next Generation Schema and Advanced Relationships to RDF.

NGS at a glance

The following objects exist in the Next Generation Schema. Here we make a clear distinction between core entities which have a unique MBID, entities which share an MBID with some core entity and perhaps other entities, and objects which are not associated with an MBID directly.

core entities that have mbids:

entities that share/borrow mbids:

just objects:

MO Mappings

mappings to the Music Ontology can be collected here. jump in and have your say :-)

proposed mappings to mo - kurtjx
type NGS RDF
core entities

with mbids

'artist' 'mo:MusicArtist'
'release' 'mo:Release'
'release_group' 'mo:SignalGroup'
'recording' 'mo:Signal'
'label' 'mo:Label'
'work' 'mo:MusicalWork'
entities

with a URI

(potentially)

'url' 'foaf:Document'
'track' 'mo:Track' or 'mo:Signal'
'medium' 'mo:Record'
objects

(no URI?)

'tracklist' absorbed into mo:SignalGroup
'artist_credit' collapse into foaf:maker relations

some notes:

  • a medium is part of a release but does not have its own mbid - what should be the URI for a medium? perhaps some hash on the end of the release URI?
  • in NGS a track simply redirects to a recording and associates a recording to a release - do we use mo:Track or mo:Signal for a track
  • tracklist and artist_credit objects are described (completely?) by properties attached to various concepts (e.g. mo:SignalGroup and mo:Signal) and require no URIs for themselves
  • what property associates a mo:SignalGroup (release_group) to a mo:Release (release)???


proposal 1 (dataincubator)

These are the mapping I have worked on as part of my http://musicbrainz.dataincubator.org// conversion

proposed mappings to mo - kurtjx
type NGS RDF
core entities

with mbids

'artist' 'mo:MusicArtist' (type=1' => mo:SoloMusicArtist, type=2 => mo:MusicGroup)
'release' 'mo:Release' and 'mo:ReleaseEvent' (1:1 mapping)
'release_group' 'mo:SignalGroup'
'recording' 'mo:Signal'
'label' 'mo:Label'
'work' 'mo:MusicalWork'
entities

with a URI

(potentially)

'url' untyped, I parse wikipedia links to create owl:sameAs to dbpedia, and discogs links for owl:sameAs to discogs.dataincubator.org
'track' 'mo:Track'
'medium' 'mo:Medium' (and mo:CD, mo:SACD etc depending on format column)
objects

(no URI?)

'tracklist' absorbed into mo:SignalGroup
'artist_alias' 'http://ontologi.es/persona#Persona'
'artist_credit' collapse into foaf:maker relations. Also want to point to a sequence of artists, similar to http://purl.org/ontology/bibo/authorList

Advanced Relationship mappings

Mapping Advanced Relationships to RDF could be done using the MuSim ontology.

A link_type becomes and sim:AssociationMethod and each link becomes a sim:Association...
