Minutes

• NIAC 2024 During the meeting, ensure people that are remote are notified that a vote is coming. Need time for offline people to digest proposals before votes.
  Use plenary vs working sessions, multiple of each per day
• NeXus front page says next meeting is code camp 2023
• Reviewed schema bugfixes in https://github.com/nexusformat/definitions/pull/1370
  • PM: sidestep by setting up a different way of specifying examples (nxdl namespace for example).
  • PJ: this is about how to provide examples of unit types in the nexus schema. Each unit type needs an example to avoid confusionRevisit discussion of general
• NXtransformations
  • AB: NXtransformations that are rotations are full basis transformations: rotation + the vector offsetHJB: non-problem, as transformation type can be omitted, for “general” basis definitions like gravity
  • PM: is there an example with the current NXtransformations are insufficient?
• PM: upcoming EU funding may be available from a broad project that includes photons/neutrons.
  • There are open calls for 1-2 year projects, 1 FTE.
  • We could apply for some funding to update toolage.
  • Call in spring (opens this friday) and sept.
  • AB: remember what the NIAC is: specs, docs/examples/validator. Maybe validator help would be useful?
  • MK: cnxvalidate could use an update? Should we have a reimplementation in python?
  • AB: Touch base with Ray for some NeXpy support?
  • PM: will think and maybe bring a proposal back
  • HB: include h5py if working on NeXpy
  • PM: looking for a library that exposes base class as python types
  • PJ: punx has this (AB to what extent?): https://github.com/prjemian/punx
  • RB: has a nxstixm file validator: https://github.com/RussBerg/nxstxm_validator
  • RB: has code for autogenerating NeXus files
