Databricks Unity Catalog has moved into business meaning: a Glossary of authoritative concepts/terms/taxonomies (preview, June 2026), Business Semantics (metric views + agent metadata, open-sourced April 2026), Domains, and Open-Semantic-Interchange-ready Metrics. This overlaps CaseTalk's territory. Investigate an interchange path so definitions created and verbalized with the business in CaseTalk can be exported into the Unity Catalog Glossary (which supports glossary import), keeping CaseTalk upstream as the source of agreed meaning while Unity Catalog governs and serves it at runtime. Assess Open Semantic Interchange (OSI) as the transport.
