Common Software Activities in Data Organisation, Management, and Access (DOMA)

This document represents the Data Organisation, Management and Access (“DOMA”) contribution to the HL-LHC Computing Review Stage 2: Common Software Activities. The document describes the four main areas requested in the charge. It is structured so as to the expose the relevant common themes and strategic directions before documenting considerations particular to each project. The first section covers the planning context, our understanding of what Run 4 computing means, major themes and looks at risks and mitigations. Next, the two common software activities Rucio and FTS are discussed, including their critical dependencies GFAL and Davix. The common storage activities are then presented. These sections use the same structure for each common activity: a general description, an overview of the project management and the team, the future plans and the associated risks. The future plan for the network technologies is then presented.
