What problem does it solve? Looking up standardized biomedical ontology terms, definitions, and hierarchical relationships across 250+ ontologies (GO, DOID, HP, ChEBI, CL, UBERON, and more) normally requires manual API calls and knowledge of OLS4 endpoints. This Skill provides ready-to-run scripts that search, resolve, and navigate ontology terms with built-in rate limiting and clean JSON output. ## Core Features & Use Cases - Term Search & Autocomplete: Search across all ontologies or filter by a specific one, with exact-match entity resolution, defining-ontology filtering, pagination, and autocomplete suggestions for partial names. - Term Details & Hierarchy Navigation: Retrieve definitions, synonyms, and annotations by OBO ID or IRI, and traverse parents, children, ancestors, descendants, plus hierarchical (part-of, develops-from) relations and full graphs. - Ontology Metadata & Statistics: List available ontologies, fetch ontology details, inspect properties and individuals, and check OLS index statistics. - Use Case: A user asks "What is the parent of myocardial infarction?" The Skill searches the Disease Ontology for the exact term, resolves its OBO ID (DOID:5844), and fetches its parent terms in two scripted steps. ## Quick Start Ask the assistant to find the definition and parent terms of a biomedical concept like "apoptosis" or "diabetes" using the EMBL-EBI Ontology Lookup Service.
