Abstract: Metadata is crucial for ensuring the FAIR principles (Findability, Accessibility, Interoperability, and Reusability)in scientific research, particularly in matter sciences, where diverse experiments and models generate vastheterogeneous data. To address these challenges, multiple metadata initiatives have emerged, enhancingdata management and collaboration.This talk presents two key initiatives: HELPMI (Helmholtz MetadataCollaboration Initiative for Plasma and Laser-Plasma Physics) and NAPMIX (Nuclear, Astro and ParticleMetadata Integration Experiments).HELPMI started the development of a domain-specific metadata frameworkfor laser-plasma physics, aligning with the Helmholtz Metadata Collaboration (HMC) and FAIR principles, andbuilding upon existing standards like NeXuS and openPMD. It focuses on easy-to-use metadata schemas forexperiments at user facilities, and interoperability to facilitate data reuse, sharing, and validation.NAPMIX, partof the OSCARS project, facilitates metadata integration across nuclear, astroparticle, and particle physics,enhancing standardization and interoperability. It aims to support cross-domain collaboration through acommon metadata framework while also providing a platform for end-user metadata generation. Thedevelopment is carried out in collaboration with international European infrastructures.This presentationhighlights the synergies between HELPMI and NAPMIX, comparing their metadata structuring, governance, andimplementation approaches. By addressing shared challenges in plasma and nuclear/particle physics, theseinitiatives contribute to a broader, interoperable metadata ecosystem. We will also explore future directions,such as cross-disciplinary metadata integration and connections with emerging researchinfrastructures. Overall, this talk underscores the importance of metadata standardization in fostering open,reproducible science.
