About OpenMetadata
OpenMetadata is an open source platform for cataloging data and managing its meaning, quality and lineage. It brings metadata, business definitions and records of decisions into one graph.
What it does
OpenMetadata captures tables, columns, dashboards, pipelines, models and their owners. Glossary terms and metric definitions give the data shared business meaning, and lineage shows how assets connect. The platform also keeps a record of corrections and approvals, so people and tools can see why a definition looks the way it does.
Key features
- Catalog for tables, dashboards, pipelines and ML models
- Lineage and ownership across the data estate
- Glossary terms and shared metric definitions
- Schema first design with over 700 open specifications
- Connectors to more than 130 data sources
Who it's for
Data governance teams, data engineers and platform teams that need one place to document and trust their data. It suits organizations that want an open source base and an active community.
Pricing and good to know
The project is open source under the Apache 2.0 licence and can be self-hosted. A managed service is offered through Collate, and the site lists a free start option for it. Self-hosting means running the platform's services and keeping them upgraded. Metadata quality depends on how well teams keep their descriptions and owners up to date.
