Enhancing Data Management in Nuclear Physics through a F.A.I.R.- Compliant Metadata Schema

Within the field of experimental nuclear physics, steps are underway to further advance good Research Data Management practices. At the heart of this is the goal of generating well-described F.A.I.R.-level experimental data and ensuring compliance with these principles. Here, we describe the landscape of Research Data Management in the nuclear physics domain, with a focus on supporting future actions with a F.A.I.R.-compliant metadata schema prototype for the community. In this work, we present a prototype metadata schema and platform (NPPilot), developed to support F.A.I.R.-compliant metadata generation and management workflows in experimental nuclear physics. The schema’s nodal, multi-layered structure supports metadata enrichment across domains, and a user-friendly generator facilitates schema customisation and export in various formats. We detail the development process, key features, and potential applications. We also describe how NPPilot will serve as the foundation for further developments through the NAPMIX project, which aims to expand its scope to a broader range of research domains. An outlook is given toward broader expansion of the schema to cross-domain physics fields.
