GRDI2020 aims at outlining the main priorities in the field of Global Research Data Infrastructures in a GRDI Roadmap, anchored on sound technical recommendations produced by two GRDI2020 Working Groups. Its outreach series of international events and thematic working meetings will increase the ability of the research community, industry, and academia to influence the development of a competitive global ICT infrastructure beyond i2010. The project will also build a qualified, trans-European Research Data Infrastructure community whose members will be inspired by common use cases and will share experiences, plan, innovate, and reach out together, with strong commitment to tackle the main relevant technical challenges.
