BioPortal Get Hierarchy

Get children, parents, or ancestors of a specific concept in a BioPortal ontology. Enables hierarchical browsing of ontology term relationships (is-a hierarchy). Use to explore narrower terms (children), broader terms (parents), or full ancestry path (ancestors). Example: get children of DOID:9351 (diabetes mellitus) to find type 1, type 2, gestational diabetes; get ancestors of HP:0001250 (Seizure) to see the full path to root.
