The webinar discussed the Accessible principle of FAIR data. Two speakers presented on how they make their data accessible: David Fitzgerald discussed how the Australian Longitudinal Study of Women's Health makes its sensitive longitudinal data accessible while protecting participants, and Jingbo Wang discussed how the National Cancer Institute makes its data accessible through online services. The webinar covered the FAIR guidelines for making data and metadata retrievable and accessible even after the data is no longer available, and discussed balancing open access with protecting sensitive data.
