Rucio is a project that provides services and associated libraries for allowing scientific collaborations to manage large volumes of data spread across facilities at multiple institutions and organisations. Rucio has been developed by the ATLAS experiment.

Rucio offers advanced features, is highly scalable, and modular. It is a data management solution that could cover the needs of different communities in the scientific domain (e.g., HEP, astronomy, biology).

Through the XDC project new features are added like the adoption of a token based approach to authentication & authorisation for data management with Rucio.
