OpenMetadata

The Open Semantic Context Platform for Data and AI

OpenMetadata is the open platform for building trusted data context and business semantics for humans, AI assistants, and agents.

OpenMetadata connects technical metadata, data quality signals, data lineage, column-level lineage, ownership, usage, policies, conversations, glossaries, classifications, metrics, domains, and data products into a unified metadata knowledge graph. With 120+ connectors, open metadata standards, semantic search, APIs, SDKs, and an MCP server, OpenMetadata gives every user and AI system the governed context it needs to discover, understand, trust, and use data.

AI does not need another raw database connector. AI needs context.

OpenMetadata provides that context:

• what data exists
• what it means
• who owns it
• how it is used
• where it came from
• where it flows
• whether it is fresh, tested, and trusted
• which business concepts, glossary terms, classifications, and policies apply
• what downstream assets, dashboards, pipelines, metrics, and ML models depend on it
