Activities

Our role was to help GSI/FAIR develop a comprehensive research data management policy that meets the needs of the organization. This involved reviewing the draft policy, identifying gaps and opportunities for improvement, and designing a customized approach that aligns with GSI/FAIR's goals, values, and objectives.

The Research Data Policy of the Helmholtz Center Berlin (HZB) was analyzed for adherence to the FAIRsFAIR Data Policy checklist and key principles within a Proton and Neutron Research Infrastructures Data Policy of the ExPaNDS Project. This enhances the quality, reproducibility, and transparency of research results and facilitate collaboration and data sharing among researchers and cross-facility.

(Meta-)data standards and repositories both play a key role on the road to FAIR. Especially if they are intentionally developed together and widely accepted. For this, visionary policies and a strong orientation towards researchers' needs are crucial. Hub Matter is currently engaged in identifying the status quo (results of a qualitative survey here) and developing further coordination opportunities.

Using the example of the large scale instrument A4 at the MAMI accelerator, we engage in the research field of high energy physics to optimize a typical data set for data publication. To increase FAIRness of the published files, various measures are applied from conversion to machine-readable formats over metadata enrichment to adding a readme file to create scientific context. The improvements are applied to the currently built next generation instrument and serve as a general approach for publishing data of the high energy physics research field.

We developed workflows around the FAIR principles for the Energy Materials In-Situ Laboratory Berlin (EMIL) at BESSY II which provides a unique analytical instrumentation in direct combination with an industrially-relevant deposition tool. The metadata collection was improved by integrating an instrument PID, an electronic laboratory book, and a sample tracking system along with staff training. An automatic (meta)data collection workflow was implemented where produced NeXus files become publicly available through the ICAT repository.

On the currently built ALPS II large-scale experiment at DESY we develop strategies to collect and organize data taking of complex, highly dynamic experimental setups. The application of the HDF5 file format for (meta)data storage in the particle physics research field is investigated to meet the NeXus standard of neutron and x-ray science. In combination with other use cases, we explore advantages and limits of the NeXus Definition Language to cover the research fields of neutron, x-ray and particle physics by a single standard.

Simulations play a crucial role in instrument design, as a digital precursor of a real-world object they contain a comprehensive description of the setup. Unfortunately, this digital representation is often neglected. To preserve the symbiosis of simulated and real-world instrument beyond commissioning we connect the two worlds at the NeXus file level. (Meta)data of the physical Aquarius beamline at BESSY II and its digital realization of the Ray-UI simulation software enrich the instrument section in sense of the FAIR principles and, thus, increases the reusability of experimental and simulation data.
