LinkedBrainz/NGS to RDF mappings
This page is for defining the mapping of Next Generation Schema and Advanced Relationships to RDF. Much of the old content has been moved to the talk page.
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:
Mappings
The current mapping decisions for mapping NGS to RDF are summarized here. The mappings make use of the Music Ontology and other ontologies. Previous mapping proposals have been moved to the discussion page.
Core
| type | NGS | RDF |
|---|---|---|
| core entities
with mbids | ||
| 'artist' | 'mo:MusicArtist' (type=1 => 'mo:SoloMusicArtist', type=2 => 'mo:MusicGroup') | |
| 'release' | 'mo:Release' | |
| 'release_group' | 'mo:SignalGroup' | |
| 'recording' | 'mo:Signal' | |
| 'label' | 'mo:Label' | |
| 'work' | 'mo:MusicalWork' | |
| entities
with a URI (potentially) | ||
| 'url' | 'foaf:Document' or 'owl:sameAs' links to DBpedia etc. | |
| 'track' | 'mo:Track' as a blank node | |
| 'medium' | 'mo:Medium' and various 'mfo' concepts | |
| objects
(no URI?) | ||
| 'tracklist' | both a 'mo:Medium' (or mfo subclass) and 'mo:Record'? | |
| 'artist_credit' | collapse into foaf:maker relations |
Advanced Relationships
Currently, only the some of the most basic Advanced Relationships are modeled.
