OpenMetadata is a unified metadata platform for data and AI, providing data asset discovery, lineage, governance, and agent context retrieval capabilities.
Key Features
- Unified metadata model — One-stop management of tables, columns, metrics, dashboards, pipelines, and ML models
- Automatic lineage — End-to-end data lineage across databases, BI tools, and orchestration platforms
- Data quality SLA — Built-in data quality testing framework with rules, SLA alerts, and failure tracking
- Data asset discovery — Full-text and column-level search so agents can find the right tables and columns as context
- Collaboration and governance — Glossary, tags, classifications, RBAC, and audit logs
- Agent / LLM integration — Provides APIs and metadata embeddings to feed data catalog context to agents
Use Cases
💡 Provide a unified data asset retrieval layer for RAG agents so LLMs can find the right business tables and column definitions
💡 Track cross-team data lineage to locate the source of data errors in agent decision chains
💡 Govern LLM training data and feature stores for compliance and traceability
💡 Centralize metrics and dashboards so agents reference consistent metric definitions when answering business questions
💡 Use metadata APIs to let AI workflows access structured data context and descriptions
