Experiments should be able to describe their data with complex metadata, made of nested fields, lists and typed values such as numbers and dates, and then trust that metadata and search any part of it quickly. This is the motivation behind DaFab's metadata work. DaFab, an EU Earth-observation project built on Rucio, extended the Rucio server to meet this requirement. Each DID carries its...

Role-based access control provides a scalable and centralized approach to authorization in distributed data-management systems by shifting the focus from individual accounts to user responsibilities. In Rucio, it extends existing permission mechanisms with scope-level controls, applies the least-privilege paradigm, and provides a generic foundation for authorizing any type of operation.
