Common Data Form Language (CDL)
SOFA conventions can be implemented without any programming by using CDL as suggested for netCDF. CDL files allow for a platform-independent interpretation of specifications and can be compiled to a binary netCDF file using the ncgen tool from the netCDF package:
ncgen -b -o mySOFAfile.sofa -k3 mySOFAconvention.cdl
The binaries of the nc-tools are available at the Unidata.
HDF5View
SOFA files can be loaded and edited in the HDFView - a viewer for HDF5 files. Note that SOFA files are based on netCDF-4, which is based on HDF5.
