Live Music Archive Linked Data
This server provides access to Linked Data that describes the audio held in the Internet Archive’s Live Music Archive (also sometimes known as "etree"). The metadata from etree has been converted to RDF and is exposed through a SPARQL endpoint along with browsable pages.
The dataset contains information describing over 100,000 performances by 4,000 artists including 1,600,000 individual tracks, each of which may be available in a number of formats.

- VoID metadata describing the dataset: http://etree.linkedmusic.org/etree
The dataset makes use of a number of vocabularies including:
- The Music Ontology: http://purl.org/ontology/mo/
- The Similarity Ontology: http://purl.org/ontology/similarity/
- The Event Ontology http://purl.org/NET/c4dm/event.owl
Artists are linked to entries in MusicBrainz, while locations of performances are linked to entries in Geonames and last.fm using a number of methods. Any such alignments are represented explicitly as similarities.
A SPARQL endpoint for the data is available at http://etree.linkedmusic.org/sparql. Some sample queries are shown below. Note that as this is currently an experimental service, query timeouts are limited.
- All artists in the collection.
- Artists in the collection with mappings to MusicBrainz.
- Artists and the locations of recorded performances.
- Artists with a count of their performances in the collection. There's a lot of Grateful Dead in there!
The Live Music Archive metadata is being made available under the CC0 1.0 Universal — “Creative Commons public domain waiver” license. Note that this only applies to the metadata supplied here. Links are given to audio materials for which other conditions may apply.
The figured below show some sample overview visualisations produced using Cytoscape. The first shows relationships between artists (pink) and the geographical locations (green) in which they have been recorded. The second shows relationships between artists (pink) and mapped last.fm venues (green) in which they have been recorded.
