  https://github.com/nexusformat/definitions/pull/1325
  OpenPMD uses defined list of dimensions and a vector for their actual

  • SB: mice to build custom units, but is it following any standard

  • CP: not really human readability and missing things like ANGLE

  • MK: other unit categories are also missing

  • NXaperture vs. NXslit

    • MK: NXslit is for simple 2-blades slits, but NXaperture is for more complex geometries (to be used with NXoff_geometry as SHAPE)

    • PJ: whenever we want to deprecate or undeprecate something, it shall be extremely well explained why we do so

    • MK: undeprecate NXaperture and make the documentation clear, so it can be properly used.

  • After voting for this and merging 1271, we can do the relase
