Egeria connectors repositories contain the code that allow non-Egeria technologies to connect into Egeria:
- Hadoop Ecosystem connectors houses the connectors for various Hadoop ecosystem components, like Apache Atlas and Apache Ranger.
- IBM Information Server connectors houses the connectors for IBM Information Server components, like Information Governance Catalog, DataStage and Information Analyzer.
- Database connectors
The samples repository contains samples of using Egeria in various ways: Ansible roles, sample data and metadata, documented demonstrations, and so on at https://github.com/odpi/egeria-samples
