PUNCH4NFDI is the consortium of particle, astro-, astroparticle, hadron and nuclear physics of the German National Research Data Infrastructure (NFDI). As such, our aim is to provide and develop infrastructure and services to scientists in the PUNCH sciences in Germany to enable data handling according to the FAIR principles – Findable, Accessible, Interoperable and Reusable, and make them available also to the whole NFDI. To achieve this, we study carefully how the different PUNCH communities currently have organised their procedures for handling data. There is already a long history of solutions for working with data. The goal is to recognise where established processes work well and where there are gaps which need improved data infrastructures.
