Minutes

New Members

• WdN is new ESRF rep where there is a new data acquistion that writes HDF5/NeXus
• LG is new rep for Eu XFEL, also NeXus compliant
• SB presents FAIRmat infrastructure project that he is working in and producing lots of new draft base classes and application definitions.
• SB asks LG about links between ontology and data files.
• CZ is new rep from ORNL (had some technical issues with microphone volume), primarily workin with Neutron sources.

Issues

• PJ asks if we still need an environment.yml file in the documentation repo
  • noone sees a need for it
• HG NFDI project would want to coordinate with FAIRmat, rather than working in parallel.

Next Release

• PJ aims to have a somewhat annual release of the definitions
• Schedule releae for March 2022

Issues

• PJ suggest dropping support for python <3.7 since 2.6 is at the end of its support period.
  • PC suggests also removing any use of the six module since it shouldn’t be need when there shouldn’t be any Python2 code
  • PC further suggests switching to h5py version3 - PJ thinks it may not be needed (happens automatically)
• PJ asks if we are ready to cut the cord from the Jenkins server? PC thinks yes. PJ waiting for acknowledgement from FA.
• PJ discusses adopting Github workflow
  • Github (branch, not yet main) will autonatically build the docs on every push and will publish it if there is a release tag provided.
  • Will wait for FA before implementing it in main.
• HG asks for details about the yml file that PJ asked her to create for the ontology repo
  • PJ says it is mostly for setting up the appropriate python/conda environment required to run the code.
• PC presents PR#957 for describing a POI.
  • mostly complete, but still an issue with declaring which fields are optional.
• PC has also been working on NXbeam to define the reference plane of the polarisation.

Next meeting to be in the second half of January, 2022. poll
