With four steps you can generate such a representation based on PoolParty data:  Continue reading

Transforming music data into a PoolParty project

Goal

For the Nolde project it was requested to build a knowledge graph, containing detailed information about the austrian music scene: artists, bands and their music releases.

LinkedBrainz data is modeled using the Music Ontology. Continue reading
