Topics to be Considered

A subset will be chosen on the first day of the meeting.

Walk through

  • Rules for multi file NeXus files
• Class specifications:
  • NXformula?
  • NXdata: Assigning axes to data once more again
  • Prepare contributed definitions for ratification
• Work on software:
  • validation tools (nxvalidate or NXvalidate): state (cf #169/defs, #251/defs, #300/defs, #363/code), further development, WWW service, use of NeXpy/Python-API for validation
  • New NAPI release?
