Only MatLab/Octave seems to be provided there, but since the
SOFA format is based on netCDF (a file format for storing array-
like data, including array shapes, dimension names, units and 
other metadata).

Existing libraries for netCDF will probably do the job, but a
'convenience layer' knowing the exact SOFA formats would probably
simplify things.

Numerical Python already has a netCDF module, so probably some
day I will add support for this in pyjacktools.



A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
