In this episode, co-hosts Emma McGrattan and Ole Olesen-Bagneux sit down with Samuel Bitrus, Data Quality and Governance Manager at Lufthansa Group, to explore the evolving role of data catalogs in large, complex enterprises.

Drawing from his work across governance, metadata, and trust, Samuel explains why data catalogs are no longer just inventories of data assets. They are becoming critical context layers that help both humans and AI systems understand what data means, where it comes from, who owns it, and whether it can be trusted.

Together, they explore:

• What a data catalog really is, beyond simple asset discovery

• Why trust, context, and accountability matter as much as findability

• How AI is changing the role of catalogs for both human and non-human users

• Why large enterprises often end up with multiple catalogs, and why that is not necessarily a failure

• The idea of a “catalog of catalogs” as a pragmatic way to connect fragmented metadata ecosystems

🎧 Tune in for a conversation on metadata, governance, enterprise complexity, and why the future of data catalogs may be less about one perfect system and more about making many systems work together.
