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 <http://www.fgdc.gov/metadata/contstan.html>. 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.
