[NeXus-committee] Feb NeXus Telco

[Wout De Nolf]

Hi Folks,

I would like to put NXxas on the agenda again if time permits:

MR: https://github.com/nexusformat/definitions/pull/1613
Current HTML rendering: 
https://nxxas-hdf5-nexus-7ba1891a1aaa2d29580131298dc337bab2b3e5de32b6ef.gitlab-pages.esrf.fr/classes/applications/NXxas_new.html

XAS comes in different flavors: transmission, partial fluorescence, 
total fluorescence, total electron yield etc.

Each of these modes define essentially what the "intensity" field 
represents. In addition each mode can have metadata associated to it 
which is specific for that mode. Although some modes might share some 
metadata, not sure yet.

In a previous NIAC the suggestion was to use the "choices" mechanism for 
this use case:

https://github.com/nexusformat/definitions/pull/1352#issuecomment-3422349124

I would like to get the opinion of the NIAC whether this is the right 
way to go.

As you can see in the HTML rendering we re-used FAIRmat's NXtransmission 
but there seems to be a conceptual problem since it is an application 
definition, not a base class:

Anyway, food for discussion.

Cheers,
Wout
