This factsheet provides an overview of the FAIRsharing database registry. FAIRsharing is a curated, informative and educational resource on data and metadata standards, inter-related to databases and data policies. It guides consumers to discover, select and use these resources with confidence, producers to make their resource more discoverable, more widely adopted and cited, and powers third party tools by providing trustworthy content to promote standards and databases. We recommend that you explore all of the FAIRsharing Educational series, created by the FAIRsharing Team and Community Champions. ---------------- This work was supported by the RDA FAIRsharing WG.
