The open-source AI context layer — powered by semantic intelligence
A single place for all your data, AI agents, and data practitioners to build and manage high quality, semantically-rich metadata assets that give both people and agents shared context at scale. Built by Collate and the founders of Apache Hadoop, Apache Atlas, and Uber Databook.
Fastest Growing Open Source Metadata Platform
Driven by an active community of thousands globally, OpenMetadata is becoming the standard open context layer for data and AI.
Why OpenMetadata?
Semantic context your AI agents and people can act on
OpenMetadata builds a living knowledge graph of your data — what it means, how it connects, and whether it can be trusted. Context drawn from data assets, documents, and organizational policies flows into a single Semantic Context Graph, giving both people and AI agents the shared understanding they need to work on your data.
API-first and schema-first, by design
OpenMetadata's schema-first architecture — with 700+ open specifications in JSON Schema and RDF/JSON-LD — makes metadata programmable and extensible. Plug into your existing stack, customize your metadata model, and build data and AI workflows that scale with your organization.
Designed for simple setup, operations, and scalability
The streamlined architecture has only four system components, making it easier to deploy, operate, and upgrade compared to other solutions. The simple user experience is designed for technical and non-technical users to collaborate together, while still having robust data practitioner capabilities, all built to meet the scalability and security requirements of enterprises.
Help people and agents find key data assets
Get the right data to the right people and agents to do their work. OpenMetadata delivers a single source of truth for all your data sources, data pipelines, and data products, with rich semantic context attached to every asset.
