FAIRsharing is an informative and educational service that increases guidance to consumers of standards, databases, repositories, and data policies, accelerating the discovery, selection, and use of these resources. It also aims to increase the satisfaction of resource producers through increased visibility, reuse, adoption and citation, and their resource. Targeted to researchers and other stakeholders involved in producing, managing, serving, curating, preserving, publishing or regulating data, FAIRsharing supports and enables the implementation of the FAIR principles.
