[NeXus-committee] DECTRIS example file

["V. Armando Solé"]

Hi Mark,

 From the info provided, it seems the linked data are at the root level 
of the (missing) linked files. Are those "external storage" datasets or 
datasets readable on their own? In the later case, I think it would be 
convenient to place them in one entry with the same name as the one in 
the master file:

master:

entry_1 (or whatever name)
      external_link "data_000001"
                  target file "th02c_ps02_1_data_000001.h5"
                  target_path "/entry_1/data"
      external_link "data_000002"
                  target file "th02c_ps02_1_data_000002.h5"
                  target_path "/entry_1/data"

linked th02c_ps02_1_data_000001.h5
entry_1 (same name as in the master)
      /data

linked th02c_ps02_1_data_000002.h5
entry_1 (same name as in the master)
      /data

The advantage would be that handling the linked or the master file would 
be equivalent while at the same time the linked files would be "NeXus" 
compliant too.

Of course I am assuming the master file is also generated by the 
detector. If not it would be too cumbersome to make sure both entry 
names are synchronized.

If that can potentially slow down things then forget about it.
