search_ontologies — Search 120 published ontologies by keyword, domain, licence, or whether their class hierarchy was verified against the published source file.
check_licence — The operative licence terms for one ontology: whether you may redistribute it, whether attribution is required and with exactly what notice, and whether share-alike propagates to anything you derive from it.
list_verified — Every id whose class hierarchy was extracted from the ontology's own published file.
recommend_ontologies — Describe what you are modelling in prose and get suggested ontologies — often a combination — with a reason for each.
