Retrieve parent, child, ancestor, and descendant terms by traversing transitive relations such as part-of and develops-from across supported ontologies like GO, DOID, HP, and UBERON using the EMBL-EBI OLS API.

Yes, you can retrieve hierarchical relationships for disease ontology terms by traversing parent, child, ancestor, and descendant relations through the EMBL-EBI OLS, following transitive relations like part-of and develops-from.

Yes, EMBL-EBI OLS supports term search and autocomplete functionality, allowing you to find ontology entries by keyword and suggest likely completions for partial names, optionally constrained to a specific ontology.

Available biomedical ontologies for term discovery and entity resolution include GO, DOID, HP, CHEBI, UBERON, and CL, enabling structured search and exact matching across these specific domains.

Yes, querying the EBI ontology lookup service enforces EBI rate-limits and terms-of-use compliance, returning structured JSON outputs with ontology catalog information and OLS index statistics for downstream analysis.
