The Observatories of the Seas Ontology (OSO) is a FAIR knowledge graph designed to describe marine observatories and support interoperability across marine data infrastructures. OSO structures key elements such as infrastructures, sites, platforms, organisations, and associated activities, enabling machine-actionable data integration and advanced exploration through semantic technologies. Developed in alignment with EMSO ERIC activities, OSO contributes to improving data discoverability, interoperability, and reuse in the context of Open Science. The ontology is publicly available, documented, and already applied to several observatories, demonstrating its ability to represent real-world infrastructures.
It provides a semantic framework for describing subsea and deep-sea observatories, with a particular focus on those operated within the EMSO-ERIC
