Deliverables and resources

According to the open science policy of the HMC project, we happily share our work.

Documents

Glossary  

• A glossary prototype for experimental data, called “Devices, Detectors and Components Library” or in short “DDC” was a mandatory deliverable of the HELPMI project:

• It can be accessed on GitHub

  • Ideally, use the .md file (which was added after publication at zenodo)

Ontology

• Initially unrelated, a different project at HZDR led to the development of an ontology for simulations in LPA. This can serve as a step towards and unified ontology for LPA data, regardless the realm (simulations or experiments). Work is to be invested to make proper definitions and to append it where possible to existing ontologies.

  • Open it visualized

  • Go to its repository

Example files

Dataset files

To make concrete, instructive examples for the community, we generated example hdf5 files in a minimal NeXus standard (no application definition). These can be viewed online thanks to myhdf5.hdfgroup.org.

• Example data from POLARIS at HI Jena: https://github.com/NeXus-for-HELPMI/POLARIS_ExpData_Example/blob/main/ShotContainer.hdf5

• Same example data from POLARIS at HI Jena, with added openPMD layer: https://github.com/NeXus-for-HELPMI/POLARIS_ExpData_Example/blob/main/ShotContainer_openpmd.h5

• Example data from PHELIX at GSI, few shots from different days: https://github.com/NeXus-for-HELPMI/PSDB_ExpData_Example//blob/main/psdb_container_nexus.h5

• Same example data from PHELIX at GSI, with added DDC metadata entries: hhttps://github.com/NeXus-for-HELPMI/PSDB_ExpData_Example/blob/main/psdb_container_nexus_minimal_ddc.h5

• Example data from PHELIX at GSI, without added DDC metadata entries: https://github.com/NeXus-for-HELPMI/PSDB_ExpData_Example/blob/main/psdb_container_nexus_minimal.h5

• Same example data from PHELIX at GSI, with added openPMD layer: https://github.com/NeXus-for-HELPMI/PSDB_ExpData_Example/blob/main/psdb_container_openpmd.h5
