A comprehensive repository of biomedical ontologies.

BioPortal is a web-based repository providing access to biomedical ontologies. It enables users to browse, search, and visualize a vast collection of ontologies in various formats, including OWL, OBO, and others. BioPortal's architecture supports ontology submission, versioning, and collaborative curation. It offers a RESTful API for programmatic access to ontology metadata and concepts. Use cases include semantic annotation of biological data, knowledge discovery, and the development of ontology-based applications. The platform supports both human and machine access, facilitating interoperability and knowledge sharing within the biomedical research community. BioPortal serves as a crucial resource for standardizing biomedical terminology and promoting data integration.
