OpenML Components

To make development easier, OpenML has been subdivided into several subprojects with their own repositories, wikis, and issue trackers: * Website itself and API services: https://github.com/openml/website * Java library for interfacing with the OpenML API: https://github.com/openml/java * R package for interfacing with the OpenML API: https://github.com/openml/r * Python module for interfacing with the OpenML API (stub): https://github.com/openml/python * WEKA plugin: https://github.com/openml/weka * RapidMiner plugin: https://github.com/openml/rapidminer * KNIME plugin: https://github.com/openml/knime

Suggestions for further integrations

• We need more data. Other people made efforts for hosting and selecting ML data already. [[Data-Repositories]] lists them. List must be extended and we need to check how much we already have integrated.

Local installation of OpenML

Developers who are working on new features may need a [[Local Installation]] for testing purposes.
