# Auto Ontology

NVIDIA released Auto Ontology, an open library that builds a context layer from enterprise metadata and tells AI agents where data lives, what a metric means, whether to use it, how to use it, where it came from, and what is similar. It generates enterprise ontologies from metadata, connects existing ontologies and semantic models, and reconciles conflicting definitions across systems. It then exposes that context to any agent harness through MCP, CLI, and API, returning provenance with every answer. The library is distributed under Apache License 2.0 and is not currently accepting external contributions.
