MOD (Metadata for Ontology Description and Publication Ontology)

MOD (Metadata for Ontology Description and Publication Ontology) is a metadata schema designed to describe semantic artefacts, such as ontologies, vocabularies, and terminologies, in a standardized and FAIR-compliant way. Developed in the RDA Vocabulary Service Interest Group (VSIG) then within the FAIR-IMPACT EOSC project, MOD is based on DCAT2 and builds on existing metadata standards like DC, Schema.org, ADMS, etc. to provide a structured framework for capturing essential information about these artefacts, including their provenance, licensing, versioning, and usage. The schema facilitates interoperability between ontology repositories and enables better discovery, reuse, and integration of semantic resources in various domains. It is the baseline for MOD-API a Web service API specification for operations on semantic artefact catalogues. MOD is openly available on GitHub, where it is maintained and extended based on community input.
