About OpenMetadata

OpenMetadata is the #1 open-source context layer for humans, AI assistants, and agents. It unifies technical context, business semantics, and organizational memory into a single Semantic Context Graph, enabling AI agents and people to reason from the same trusted foundation. Built by the founders of Apache Hadoop, Atlas, and Uber Databook, OpenMetadata provides a unified metadata platform with a central metadata repository, in-depth column-level lineage, and seamless team collaboration. It is schema-first and API-first, with 700+ open specifications in JSON Schema and RDF/JSON-LD, and integrates with over 130 data connectors. Features include data discovery, data observability, data governance, quality, collaboration, lineage, AI readiness via an MCP server, AI SDK, and Context Center. The architecture is streamlined with only four system components, making it easy to deploy, operate, and scale.
