The CF Conventions

  http://www.cgd.ucar.edu/cms/eaton/cf-metadata/CF-1.0.html

are becoming more widely used than any other, so I recommend at least
indexing their "standard_name" attribute 

  http://www.cgd.ucar.edu/cms/eaton/cf-metadata/standard_name.xml

for identifying model parameters or observational data by a canonical
name.  It's more useful than "long_name", for which there is no
maintained standard.

"edu.ucar.unidata.netcdf" seems like an excellent UTI for netCDF data.
I see no problem with using it.  I'll recommend its use for anyone
else who needs a UTI for netCDF data.
