FAIRmat develops concepts for paving the way to enable FAIR research data in solid-state physics. For selected theoretical data in this field, the NOMAD portal has developed mature concepts and technological solutions for storing data according to the FAIR principles. Extending this approach to experimental data is challenging due to their diversity and missing standards. In this paper we present our comprehensive approach to establish FAIR data in the field of experimental solid-state physics despite its heterogeneity. The concept includes elaboration of standards, community building and methods that facilitate the community’s transition to FAIR standards.
