BioPortal SPARQL is a service to query BioMedical ontologies using the SPARQL standard. Ontologies have been transformed into RDF triples from their original formats (OWL, OBO and UMLS/RRF, ...) and asserted into a triple store.

Notice: This SPARQL endpoint is maintained by NCBO for demo purposes. It serves as playground to explore BioPortal's ontologies in RDF and we do not recommend its use for production applications or heavy batch processing. As an alternative, our virtual appliance is packaged with a SPARQL endpoint that can be used for local deployments.
