The supplied reports describe NVIDIA’s open-source Auto Ontology as a semantic catalog and business-ontology system for natural-language SQL generation over structured data. It ingests database metadata to draft terms, column mappings, relationships and reusable SQL attributes, which users can revise and certify before query agents use them to retrieve context, generate and check SQL, and execute queries. The project exposes Web, authenticated REST API, CLI and MCP interfaces. The reports caution that generated definitions require business-owner approval, final SQL is still model-generated, and successful execution does not guarantee a correct business answer. They also note validation, retry and fallback paths, meaning returned SQL should not automatically be treated as a successfully executed or authoritative result.
