MarkTechPost reports NVIDIA released Auto Ontology under Apache 2.0: a semantic layer that sits between agents and warehouses (Databricks/Postgres/Snowflake/DuckDB), generates a starting ontology from metadata, and exposes read-only MCP tools so agents query certified definitions rather than raw schemas. NVIDIA says internal tests cut ontology build time about 90%; primary NVIDIA developer page was not re-opened in this run.
