Open Music Ontology

The Open Music Ontology (OMO) is a minimal, non-authoritative bridge vocabulary designed to connect open cultural heritage and research metadata with common music-industry identifiers and release categories.
It does not introduce new conceptual models; instead, it reuses and links existing standards from both the public and commercial domains — including DCAT-AP, DCTERMS, EDM, CIDOC CRM, Records in Contexts (RiC), ISRC, ISWC, and DDEX.

Developed within the Open Music Observatory, OMO provides a lightweight semantic layer for integrating sound-recording, work, and release information across library, rights-management, and research datasets.
It supports interoperability in initiatives such as the Slovak Comprehensive Music Database (SKCMDb) and Open Music Europe data spaces.

This record contains the ontology’s Turtle (.ttl) source file and related documentation.
Version 0.1.0 is a proof of concept, released for community review and feedback.
