open-metadata/OpenMetadata

open-metadata/OpenMetadata is an Apache-2.0-licensed, Java + TypeScript-built open-source unified metadata platform that ships connectors for 80+ data sources, a knowledge graph for data lineage, a data-quality engine, and an AI-ready metadata API that lets LLM agents and RAG systems query data context, ownership, schema, and lineage the same way they query a vector store, so data platform teams a

Why it matters

Useful for data platform teams and AI builders who need a single metadata surface that LLM agents can query for schema, ownership, lineage, and data quality, because OpenMetadata ships an Apache-2.0 Java + TypeScript platform with 80+ data-source connectors, a knowledge-graph-backed lineage graph, a data-quality engine, and an AI-ready metadata API, which means a RAG system or coding agent can ans

Who should use it

Data platform teams who need an Apache-2.0 unified metadata platform with 80+ connectors, knowledge-graph-backed lineage, and a data-quality engineAI builders who need an AI-ready metadata API that LLM agents and RAG systems can query for schema, ownership, lineage, and data qualityEnterprises that want a single metadata surface that LLM agents, BI tools, and data engineers can share instead of parallel metadata pipelines

Who should skip it

Skip if the source link, docs, or setup requirements do not match your workflow.

Risk explanation

It connects to 80+ data sources and exposes metadata + lineage + data-quality scores, so audit which connectors are enabled, confirm the credential storage boundary, and lock down which metadata fields are visible to the AI-ready metadata API before pointing LLM agents at it.
