Enterprise data catalogs: what IAM and governance teams need now

TL;DR: Enterprise data catalogs are becoming the control point for discovery, ownership, lineage and trust across fragmented data estates, according to Collibra. In the AI era, they matter less as inventories and more as governance infrastructure that determines whether teams can use data confidently and compliantly.

Questions worth separating out

Q: How should organisations govern data reuse in AI and analytics programmes?

A: They should require a governed catalog entry before reuse, with ownership, lineage, classification, and policy context visible in one place.

Q: Why do fragmented metadata stores create governance risk?

A: Fragmented metadata stores leave business meaning, lineage, and ownership disconnected, so people cannot reliably tell what a dataset is, who is responsible for it, or whether it is approved for use.

Q: What signals show that a data catalog is working as a control?

A: Look for faster certification decisions, fewer manual clarification requests, clearer dataset ownership, and better traceability from source to use.

Practitioner guidance

• Map catalog ownership to business accountability Assign a named owner and steward to each high-value dataset so review, exception handling, and definition changes have a clear decision path.
• Link lineage to certification decisions Do not certify datasets for analytics or AI use until lineage, source system, and transformation history are visible in the catalog.
• Use classifications to gate reuse Apply sensitivity and purpose classifications so teams can see whether a dataset is approved for training, retrieval, reporting, or broader sharing.
