# Information regarding Format
# Format 1.0
# NXtomo entry (one per acquisition)
# |-> beam
# |-> incident energy (optional 0D)
# |-> instrument (NXinstrument)
# |-> detector (NXdetector)
# |-> count_time (optional 1D dataset)
# |-> data (mandatory 3D dataset)
# |-> distance (optional 0D dataset)
# |-> field_of_fiew (optional str)
# |-> image_key (madatory 1D dataset)
# |-> image_key_control (optional 1D dataset)
# |-> x_pixel_size (float)
# |-> y_pixel_size (float)
# |-> sample (NXsample)
# |-> name (optional)
# |-> rotation_angle - mandatory (1D dataset in degree)
# |-> x_translation - optional (1D dataset)
# |-> y_translation - optional (1D dataset)
# |-> z_translation - optional (1D dataset)
#
# Format 1.1:
# * move beam to the NXinstrument
# * Keep compatibility by providing a link to beam at the root level
# * add optional dataset instrument/name
# * sample/name is moved to title
# * sample/sample_name is moved to sample/name
# * add NXsource under instrument:
# |-> instrument (NXinstrument)
# |-> source (optional NXsource)
# |-> name (optional)
# |-> type (optional)
