Relation Types
Every edge in the Ontology Studio graph, and every option in its Relationship Type filter, is backed by a relation type definition. Collate ships a set of system-defined types (Related To, Part Of, Broader, Synonym, and others) and lets admins add their own to model relationships specific to their domain. Manage them at Settings > Governance > Glossary Term Relations. The page is admin-only.
