FAIRsharing is an informative and educational resource on interlinked standards, repositories and policies, three key elements of the FAIR ecosystem. FAIRsharing promotes the existence and value of these resources to aid data sharing and consequently strengthen scholarly communication. FAIRsharing aims to foster a culture change within the research community such that use of databases and standards for FAIRer data is pervasive and seamless. This is achieved by guiding consumers to discover, select and use these resources with confidence. FAIRsharing is adopted by funders, publishers and communities across all disciplines.
