Beschreibung
HELPMI is a 2-year project with the framework of the Helmholtz Metadata Collaboration, conducted by GSI, HI Jena and HZDR. The aim is to start the development of a F.A.I.R. data standard for experimental data of the entire laser-plasma (LPA) community. Such standard does not yet exist, but it would facilitate management and analysis of usually quite heterogeneous experimental data and logs by rich and machine-actionable metadata,
allowing automated processing of broad and long data sets.
To date, the LPA community is widely using openPMD, an open meta-standard, for simulation data. NeXus is a similarly hierarchical and extensible standard for various experimental methods of the Photon and Neutron science community.
Within HELPMI, we are adopting the NeXus standard for LPA experimental data and simultaneously extend openPMD and its API for custom hierarchies like NeXus. Thereby we can achieve interoperability of the standards,
circumventing the need for another standard. Alongside we started developing a glossary of LPA experimental terms in order to achieve re-usability.
We will present the current status with demonstration datasets in order to showcase the possibilities. Further information can be found at https://laser-plasma-metadata.org/ .
