description: Music Metadata Ontology for Linked Open Data (MeLOD) is an ontology for describing musicological metadata, particularly focused on musical work and source catalogues. It serves as data model for a new RDF-based version of the Metadata Editor and Repository for MEI Data ([MerMEId](https://mermeid.edirom.de/about.html)), modernizing the old editor which was based on MEI 4.0.1. The modernization of this editor is funded by the German Research Foundation (DFG) through the project [MerMEIding to the future – Ein Community-basiertes Nachhaltigkeitsvorhaben für qualitativ hochwertige Metadaten in der digitalen Musikwissenschaft (project no. 528785591)](https://gepris.dfg.de/gepris/projekt/528785591). The ontology is derived from the MerMEId data model and extends its capabilities through semantic web technologies. The concepts are based on the [MEI (Music Encoding Initiative)](https://music-encoding.org/guidelines/v5/content/index.html) guidelines and are mostly linked to the corresponding MEI elements. It implements the FRBR (Functional Requirements for Bibliographic Records) conceptual model, organizing musical information into Work, Expression, Manifestation, and Item levels. MeLOD integrates established ontologies including [Schema.org](https://schema.org/), [LRMoo](https://cidoc-crm.org/lrmoo), [CIDOC-CRM](https://cidoc-crm.org/html/cidoc_crm_v7.1.3.html) and [DoReMus](https://data.doremus.org/ontology/) to provide a rich semantic framework for music metadata. It maintains compatibility with the [MEI (Music Encoding Initiative)](https://music-encoding.org/guidelines/v5/content/index.html) XML Schema Version 5.1, ensuring interoperability with existing MEI-based systems. The ontology supports detailed description of musical works, including their expressions, performances, physical sources, and bibliographic information. It accommodates complex musical concepts such as instrumentation, incipits, keys, and meters, while also capturing contextual information about people…
