Researchers often cannot fully exploit the enormous potential of research data to address diverse scientific questions because data from different sources cannot be linked or hypotheses arise only at a later stage. To ensure efficient use of health data and expand research capacities, researchers must publish data according to established standards and share them with external partners. The FAIR-principles provide the basis for appropriate processing and documentation of data, ensuring they are Findable, Accessible, Interoperable, and Reusable.
