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). About the presentation: This presentation was delivered during a webinar for the Koninklijk Nederlands Meteorologisch Instituut (KNMI)/Royal Netherlands Meterological Institute. Part I of the presentation provides more detailed information about the technical infrastructure to support FAIR data.
