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
