Welcome to the National Center for Biomedical Ontology’s BioPortal. BioPortal is a Web-based application for accessing and sharing biomedical ontologies.
BioPortal allows users to browse, upload, download, search, comment on, and create mappings for ontologies.
Users can browse and explore individual ontologies by navigating either a tree structure or an animated graphical view. Users can also view mappings and ontology metadata, and download ontologies.
Additionally, users who are signed in may also submit a new ontology to the library. All submissions to the library are reviewed.
