Parks stewards need Catalog Explorer to show who last changed trail-closure schemas. Which governance metadata should they rely on?

Owner and history metadata in Catalog Explorer for the trail-closure schemas is the governance metadata parks stewards should rely on to see who last changed those schemas. Unity Catalog records ownership and change history on securable objects so stewards can attribute DDL and stewardship actions without informal side channels.

Table details and column statistics in Catalog Explorer for the trail-closure tables fail by concept because they describe data shape and value distribution, not who last changed the schema, so they cannot attribute ownership or DDL actors. The data lineage graph in Catalog Explorer tracing upstream sources for trail-closure tables shows where data comes from, not who last modified the schema, so it cannot answer change-attribution questions. Share grants and user permissions in Catalog Explorer for trail-closure schemas control access to the data, but they do not record schema ownership or the history of DDL changes, so they cannot show who last changed the schemas.

Exam caveat: Owner and history answer stewardship and change attribution; lineage answers upstream/downstream data dependencies. Both appear in Catalog Explorer but solve different municipal governance questions. Ownership transfer should be intentional when staff rotate off parks data products so history remains interpretable.

Operational check: Open the trail-closure schemas in Catalog Explorer, verify owner fields reflect current parks stewards, review history for the latest DDL actors and timestamps, and confirm the team does not rely on table details and column statistics, the data lineage graph, or share grants and user permissions to determine who last changed a schema.
