Observatories of the Seas Ontology (OSO)

Observatories of the Seas Ontology (OSO) is a semantic framework designed to describe marine observatories, research infrastructures, regional facilities, sites, platforms, organisations, cruises, and related observing activities. It supports FAIR data management, semantic interoperability, and integration of information related to marine observing systems, with a particular focus on EMSO ERIC. This release (v1.1.0) is a major ontology refactoring with strengthened semantic interoperability, extensive enrichment of the marine observatory knowledge graph, broader reuse of community standards and external identifiers, enhanced geospatial modelling, and improved FAIR compliance.
