Beatles Music Ontology

This project presents an ontology (IRI: http://example.org/beatles/) designed to represent and explore metadata related to The Beatles’ music.

The ontology models key musical concepts such as tracks, albums, performers, production roles, and instruments. The ontology was created using Protégé, where the core classes and properties (T-Box) were defined and saved in OWL (.owl) format.

The A-Box was populated using Python, primarily with the help of the rdflib and SPARQLWrapper libraries then saved as an owl file. The primary objective was to build an ontology capable of combining information from multiple external sources and making it easily queryable. To achieve this, data was collected from the WASABI SPARQL endpoint and enriched using the MusicBrainz and AcousticBrainz API.

This enabled the integration of the following types of data:

• Track and Album data (title, tracklist, duration)
• Track contributions (writers, composers, lyricists, translators)
• Performance data (musicians, instruments, vocal roles)
• Production details (engineers, producers, technical roles)
• Studio and location information (recording, mixing, editing)
• Acoustic and tonal metadata (BPM, key, tuning frequency, danceability)
