| Summary: | Rucio, the distributed data management system of the ATLAS experiment
already manages more than 400 Petabytes of physics data on the grid. Rucio
was incrementally improved throughout LHC Run-2 and is currently being
prepared for the HL-LHC era of the experiment. Next to these improvements
the system is currently evolving into a full-scale generic data management system
for application beyond ATLAS, or even beyond high-energy physics. This
contribution focuses on the development roadmap of Rucio for LHC Run-3,
such as event level data management, generic meta-data support and increased
usage of networks and tapes. At the same time Rucio is evolving beyond the
original ATLAS requirements. This includes additional authentication mechanisms,
generic database compatibility, deployment and packaging of the software
stack in containers, and a project paradigm shift to a full-scale open source
project..
