EURIO

The EURIO (EUropean Research Information Ontology) Knowledge Graph publishes CORDIS data about research projects funded by the European Union's framework programmes for research and innovation - FP7, Horizon 2020, and Horizon Europe - as linked data. It covers projects together with their grants, payments, and monetary amounts; the organizations that participate in them and the roles those organizations play; and project outputs including deliverables, publications, journal papers, and proceedings papers, alongside SKOS reference data for countries, funding schemes, programmes, and topics. When queried on 2026-08-06 the graph held 26,429,912 triples, including 80,208 projects, 72,534 organizations, and 696,156 results. Entities are minted in the http://data.europa.eu/s66# namespace. The graph is published by the Publications Office of the European Union both as a full dump and as per-entity named graph subsets, each available in RDF/XML, Turtle, N-Quads, N-Triples, and JSON-LD, and is queryable through a public Virtuoso SPARQL endpoint on the CORDIS Datalab. Its schema, the EURIO ontology, is aligned with EU ontologies such as DINGO and FRAPO and with widely used vocabularies including schema.org and the W3C Organization Ontology.
