Harmonization concepts for experimental research data: NOMAD and NeXus

In order to achieve interoperability for data of different origin, a FAIR research-data platform for solid-state physics is created within FAIRmat, which we term NOMAD. It features flexible, but structured data modeling, allows custom data ingestion, while providing efficient search capabilities and online visualization of datasets. Several standard data formats are supported by NOMAD including the NeXus format [1].

In this tutorial, I will introduce NeXus as a community-driven data modeling standard for experiments. I will present the NeXus Ontology and discuss several examples of how a specific experimental community can extend it to cover their special needs. Finally, the integration of NeXus data from experiments into NOMAD will be introduced.
