TL;DR: Business context, lineage, ownership and compliance can stay aligned across an open lakehouse through bi-directional metadata synchronization between Collibra and Google Cloud Knowledge Catalog, so data teams can trust what they are using for AI and operational decisions, according to Collibra. The practical issue is not catalog coverage alone, but whether governance and technical reality stay synchronized as data estates change.
NHIMG editorial — what this means for NHI practitioners
Questions worth separating out
A: They should treat synchronization between governance and platform metadata as a control requirement.
Q: Why does bi-directional metadata sync matter in open lakehouse environments?
A: Open lakehouses move quickly across distributed storage and analytics layers, so one-way governance leaves stale records behind.
Q: What breaks when data governance lacks business context?
A: Teams lose the ability to judge whether data is authoritative, who is accountable for it and what level of trust is justified.
Practitioner guidance
- Map metadata ownership to governance responsibilities Document which team owns lineage, definitions, quality and policy for each high-value dataset, then verify that those attributes are present in both the governance layer and the cloud catalog.
- Validate bidirectional sync before expanding AI use Test that changes in the governance system appear in the cloud fabric and that technical discovery changes return to the system of record.
- Tie access decisions to business context Require lineage, quality and ownership signals before approving sensitive analytics access or downstream AI consumption.
What's in the full announcement
Collibra's full article covers the operational detail this post intentionally leaves for the source:
- The exact bi-directional integration flow between Collibra and Google Cloud Knowledge Catalog for governed metadata exchange.
- How Dataplex receives outbound governance context and returns inbound discovery signals to the system of record.
- What joint customers can observe in the public preview of the integration inside Google Cloud workflows.
- The live demonstration details presented at Google Cloud Next 2026, including the workflow context shown at the booth.

Bi-directional metadata sync is becoming a control boundary, not a convenience feature. When governance data flows in both directions, the organisation is no longer relying on periodic manual reconciliation to maintain trust. That changes the operating model for data, AI and identity teams because the control record can remain closer to the technical estate. The implication is that metadata drift should be treated as governance failure, not housekeeping.
A few things that frame the scale:
- The average organisation believes more than 1 in 5 of their non-human identities are insufficiently secured, according to The 2024 ESG Report: Managing Non-Human Identities.
- Enterprises that have experienced a compromised NHI averaged 2.7 separate incidents in the past 12 months, according to Oasis Security & ESG.
A question worth separating out:
Q: How do security and data teams know whether governance controls are actually working?
A: They should test whether metadata changes, ownership updates and discovery signals are reflected consistently across both the governance platform and the cloud environment. If current state cannot be reconstructed from both sources, the control is not functioning as intended.
