The Ontology Lookup Service is a spin-off of the
PRIDE project, which required a
centralized query interface for ontology and controlled vocabulary
The OLS provides a web service interface to query multiple ontologies
from a single location with a unified output format.The OLS can integrate any ontology available in
the Open Biomedical Ontology (OBO) format.

External collaborators have provided an R package to connect to and query the OLS. It is available
described on the bioconductor
