[netCDF #LGB-565434]: NetCDF OGC compliance question

Hello,

The first link from opengeospatial.org is not referring to the netCDF software 
itself, but rather the CF metadata conventions which use netCDF as an 
underlying data mode/storage format.  So to ask if netCDF, in and of itself, is 
OGC compliant is a little misleading.  NetCDF data files which adhere to the 
CF-netCDF metadata convention appear to be OGC compliant.   There is nothing 
about a netCDF file, however, which enforces OGC compliance.  It depends on the 
provenance of the file.

The current draft of the CF conventions refer specifically to netCDF3, I 
believe; perhaps the netCDF4 files being referenced adhere to the metadata 
conventions, but use the netCDF4 storage format?  I can't say for certain, 
unfortunately.

I hope this helps,

-Ward
