Small Items

Axis attributes on fields

The current documentation describes that the fastest varying dimension is annotated with “axis=1”. In practice the slowest varying dimension is “axis=1”.

Geometry order of operations

When looking at a geometry is the orientation applied before the translation or the other way around.

XESraw

scanning environment variables

• Make sure we have an example of scanning an environment variable in scanraw
• Consider how parametric scans will be represented (within and between entries)

Later

• sequencing entries and measurements
• counting time for each data point
  • Does this belong to some base class?
  • Which one?
• implement a versioning system
  • switch to subversion
  • use SVN tagging system

Proposed Agenda Items

• Discuss NeXus collaborating with imgCIF. see MEDSBIO proposal
• Request institutes from the NeXus community sponsor a full-time technical secretary for next 12-24 months.
• (completed) Institutes that write NeXus files are data providers.. NeXus provides an interface between data providers and data requirers. Discuss if the NIAC constitution should be change to allow data requirers e.g. DANSE to have representation on the NIAC as a stakeholder that requires NeXus.
• (working) SCAN definition similar to TOFRAW definition
• (working) NXcharacterization needs to be formalized
• (working) Finalize archive definition
