Ontology Term List (Ontobee)

ontobee/list-terms

Lists the terms of one OBO Foundry ontology from Ontobee (He Group, University of Michigan): for each term its IRI, label, parent term IRI and label, alternative terms (synonyms) and definition. `ontology` is one of 9 ontologies (for example SO, RO, BFO, TRANS). A term with several parents appears on several rows. At most the first 500 rows are returned, in Ontobee's order, with `totalRows` and `truncated` saying how many exist. Each ontology carries its own licence. Ontobee data, reshaped to JSON and served by Eden Engine; not an official Ontobee product.
