The complexity and size of photoemission data is rapidly increasing as new technological breakthroughs have enabled multidimensional parallel acquisition. However, most of the community is currently using heterogeneous data formats and workflows. We propose a new data format based on NeXus, a hierarchically organized hdf5 structure. This multidimensional photoemission spectroscopy format is designed to allow high-performance automated access, enabling experimental databases for high-throughput material search. Our approach involves reaching out to the community using a website with extensive documentation of our proposed standard. As a demonstrator of the potential of our approach we present a workflow and data pipeline integrated into the NOMAD research data management solution, which provides powerful analysis and search functionalities.
