Relationships

Relationships HTTP endpoints — paginated list with type filter (ERD / GRAPH / ALL) plus per-type detail endpoints.

RelationshipController exposes three endpoints. The same payloads are surfaced on the source and target dataset's detail pages — when a dataset participates in any relationships, those are listed under the dataset's relationships cluster. For the cardinality model (ONE_TO_EXACTLY_ONE / ONE_TO_ZERO_OR_ONE / ONE_TO_ONE_OR_MORE / ONE_TO_ZERO_ONE_OR_MORE), the per-adapter ingestion coverage, and the ERD vs graph relationship distinction, see the Relationships page.
