[Nexus] NXxas structure for multiple datasets

[Fernan Saiz]

Dear Nexus community,

I would like to enquire to any of the XAS users here about the structure 
they employ to build hdf5 files when XAS is used to study chemical 
reactions. For this specific problem, here in ALBA the user needs to 
collect the XAS spectra every few minutes as well as the temperature, 
pressure, and the concentrations of the involved chemical species 
(reactants and products) every several seconds. This data collection 
takes place during long periods of time of up to a few days.

Hence, I would to know if it would be more convenient to lump all these 
measurements in one NXentry, which would contain data and metadata for 
all these physico-chemical properties; or instead, to write different 
NXentries for each one of them (e.g. one NXentry for temperature, 
another one for pressure, and so on).

Sincerely,
