NVIDIA has officially released Auto Ontology, an open-source library distributed under the Apache 2.0 license. This tool is specifically designed to automatically generate a semantic layer derived directly from enterprise metadata, helping artificial intelligence agents interact with database SQL queries with greater accuracy and reliability.
The core function of the library is to ground AI agent SQL queries in certified definitions, significantly reducing errors caused by inconsistent data interpretations across various departments. By establishing this foundational layer, the system ensures that AI models operate on verified business logic.

Regarding accessibility and integration, Auto Ontology serves context seamlessly through multiple channels including the Model Context Protocol (MCP), command-line interface (CLI), and application programming interfaces (APIs), allowing developers and organizations to integrate it flexibly into their existing data infrastructures.
A semantic layer acts as a crucial bridge between complex database architectures and natural language prompts used by AI agents. By open-sourcing Auto Ontology, NVIDIA empowers organizations to enforce data governance and minimize hallucinations when AI systems attempt to query large-scale enterprise data warehouses.
