A Vision for Global Research Data Infrastructures GRDI2020 aims to define a framework of technological, organizational, & policy recommendations to guide the development of an ecosystem of Global Research Data Infrastructures. The project activities are aimed at mobilizing user communities, international initiatives, leading experts and policy makers worldwide in the GRDI2020 plan.GRDI2020 is submitted at a crucial time since large data infrastructures have been developed that require integration onto a new expanded Global Data Infrastructure.
