Hi Charlie,

I'm interested in how you are using the CFChecker code. Are you using the code form the CF SVN [1] or the packaging I maintain based on the same codebase [2], or is this independent code? Have you applied any patches to the version you use in ncdismember? It would be good to keep any improvements to the code in the main line.

Thanks,
Stephen.

Subject: [CF-metadata] Update on ncdismember (+CFchecker) for hierarchical files
Hello CFers,
A few months ago I introduced ncdismember, a script that uses the netCDF Operators (NCO) to dismember hierarchical netCDF-compliant files into netCDF3-compliant (flat-) files, then calls CFChecker on those. It is a simple (one-line) procedure that checks CF-compliance of all groups in hierarchical netCDF4/HDF5 files.
The recent releases of NCO 4.4.0 and netCDF 4.3.1-rc7 bring significant new features to ncdismember...
1. Works on all groups in netCDF4/HDF5 files. Not only leaf groups.
2. Works on HDF4 files. No prior conversion to netCDF necessary.
3. Automatically translates input to netCDF3-supported types (e.g.,
   nc_string->nc_char, nc_ubyte->nc_short).
4. Is faster: Uses CFChecker batch mode and avoids temporary output.
Example input (*.nc, *.hdf, *.h5, *.he5) and output (*.txt):

Feedback welcome on relevant NCO SourceForge forum https://sourceforge.net/p/nco/discussion
Enjoy,
Charlie
