What Egeria is

Egeria is an open-source project for making metadata and context interoperable across people, tools and platforms used in AI and data science. Its open metadata schema has more than 600 types for describing an enterprise’s digital business. Specialist servers can capture, analyze, search and manage metadata, as well as extract, store and synchronize information across technologies. Egeria also supports metadata exchange, linking and federation between different repositories.

Its catalog of capabilities includes integrated cataloguing, lineage management, metadata discovery, metadata security and synchronized access control. Discovery functions cover schema extraction, resource profiling, and data class, grain, semantic and classification discovery. Connectors span integration, repositories, runtime and security, with a REST client connector also listed. Documented content packs cover PostgreSQL, Microsoft SQL Server, Oracle Database, Db2 for LUW, DuckDB, Unity Catalog, Apache Atlas and Apache Kafka. Interfaces include Egeria Explorer, Lineage Explorer, Data Mesh, The Catalog, Egeria Operations and Egeria Audit. The frameworks are designed for custom types, variations and systems. Egeria can run in a Docker container, standalone or as part of Kubernetes deployments. The community edition is free to use and includes functions for an Egeria developer.
