About the presentation: A presentation about the development of the 4TU.ResearchData community delivered during the final day oft the Research Data Netherlands (RDNL) Essentials for Data Support (E4DS) course. About the speaker: Dr Connie Clare, 4TU.ResearchData, Netherlands. Connie Clare is the community manager of the 4TU.ResearchData community. 4TU.ResearchData is an international data repository for science, engineering and design disciplines. Built around the technical infrastructure, the online community comprises researchers, research data supporters (data stewards, data managers, research software engineers, IT and communications specialists) and technical experts (repository back office staff). The goal of the community is to provide an inclusive space for members to connect and exchange knowledge about best practices for the creation and reuse of FAIR data within diverse scientific domains. This includes the development and provision of discipline-specific guidance, training and resources to support researchers in making their data Findable, Accessible, Interoperable and Reusable (The FAIR Principles).
