If I might rephrase/expand on Rich's comment:
I think we are trying to add relevant metadata, notably CF and ACDD
http://www.unidata.ucar.edu/software/netcdf-java/formats/DataDiscoveryAttConvention.html
metadata to the dataset (sometimes via ncml).
Keeping the data and the canonical version of the dataset's metadata
together is a goal of CF.
That dataset metadata can be harvested by programs like ncISO (and others)
which can generate ISO 19115 metadata.
That ISO 19115 metadata can be harvested using GI-CAT or GeoPortal Server
(and others).
