Towards coherent metadata schema for the PUNCH4NFDI open science platform

PUNCH4NFDI is an NFDI consortium of particle, astro-, astroparticle, hadron and nuclear physics, which is addressing common challenges of data-intense physics at large research facilities: data volumes, data complexity, data rates, and data irreversibility, as well as the development and promotion of open science vision and required tools to achieve this. One of the core features in the development of a PUNCH4NFDI software infrastructure is a cloud-based platform and an open data portal, aimed at providing access to a wide range of digital research materials within the PUNCH4NFDI community and ensuring that the FAIR (findability, accessibility, interoperability, reusability) principles are applied for the community's data collections. This requires to navigate the landscape of different established metadata schemas and find common ground to access the data and run programs and workflows using data from different data collections. In order to achieve this goal, we have investigated core concepts and definitions in the field and analyzed user stories and use cases of several data platforms within the PUNCH4NFDI community. From these, essential requirements for the used metadata have been defined. ... mehrThe results will be presented in this contribution.
