From the Past To the Future: Legacy Data in Small and Medium-Scale "PUNCH" Experiments - a Blueprint for PUNCH and Other Disciplines

The main goal of PATOF is to make the data of a number of participating experiments fully publicly available and FAIR as far as possible. The work is building on first experience gained at the Mainz A4 nucleon structure experiment (1999-2012). Here, the analysis, reorganisation, preparation and subsequent publication of the A4 data and A4 analysis environment according to FAIR principles shall be achieved. The lessons learned at A4 are then to be applied to other experiments at DESY (ALPS II, LUXE) and Mainz (PRIMA, P2), collectively called APPLe experiments. In the process, a general and living cookbook – or at least a first collection of recipes – on how to create metadata for PUNCH experiments and how to make their data FAIR is also aimed for. The cookbook will capture the methodology for making individual experiment-specific metadata schemas FAIR. Another output is the "FAIR metadata factory", i.e. a process to create a naturally evolved metadata schema for different experiments by extending the DataCite schema without discarding the original metadata concepts.
