      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.},
