The Strategic Research, Innovation and Deployment Agenda (SRIDA) will define the vision, overall goals, main technical and non-technical priorities, investment areas and a research, innovation and deployment roadmap for data-intensive science and infrastructures. While the core focus will be on the challenges of HEP and RA, the project will validate proposed technical and strategic solutions with other data-intensive science cases to ensure that other disciplines with similar challenges can benefit from the project results.
