Re: NSDL metadata for THREDDS datasets

The danger in choosing something simpler "to get started" is that once
chosen it is very difficult to get rid of.


This appears only to address educational documents or modules, not
datasets.  Perhaps that is all you need, but you also wrote:

# In particular, we plan to start with the types of data found on many
# THREDDS servers:
#   -- gridded data output from weather forecast models,
#   -- GOES satellite imagery, NEXRAD level 3 images, and
#   -- point source weather observations and balloon soundings from weather 
#      stations
#   -- climate data

I recommend you consider whether a subset of FGDC CSDGM or ISO 19115
would meet your needs for dataset description.  Only some of the fields
therein are required.  See <>.

Note also that specifications like the OGC Web Map Service have explicit
support for linking to FGDC or ISO metadata, and that the Office of
Management and Budget's e-government "Geospatial One-Stop" initiative
will be using FGDC metadata.
