A collection of species-specific developmental stage ontologies. The custom version of this ontology generated for Bgee and information on how to create it are available on GitHub.
Ontology describing homology-related concepts, notably used in our annotations of similarity between anatomical structures.
Bgee uses the cross-species ontology Uberon covering anatomical structures in animals. A custom version is generated for Bgee. Steps explaining how and why this custom version is generated are described on GitHub. We also manually modified mapping to terms from external ontologies.
