The GeRDI project focuses on the development of a sustainable Generic Research Data Infrastructure. Its goal is to enable scientists to search, use and re-use external research data. In the current pilot phase, the software development is driven by research questions. These questions originate from participating communities in various research disciplines – marine sciences, but also digital humanities, bioinformatics, and others. An exemplary research question is “How marine fisheries impact on global food security up to 2050”.
