I do not know enough about GDS to answer, but to do it as you want
would require the GDS to have a hierarchical catalog which it does
not. The alternative is to do as we have done on some sites, build
your own subset catalogs for TDS and then only point at the GDS for
the OPeNDAP service. Take a look at:
http://oceanwatch.pfeg.noaa.gov/thredds/catalog.html
and look at the first few non-satelite datasets. They are actually
being served by a OpeNDAP DRDS server from a database. We created
the sub catalog ourselves and then point to the OpeNAP html page for
that service. It is a little more work but I think it will do want
you want.

Thanks, Roy. Apparently an unencoded ampersand (&) is the problem in
the GDS catalog that is causing the XML parser to fail. However, I
notice that adding /xml or /catalog.xml to any of the GDS datasets
sends me back a complete dataset listing for the entire GDS catalog,
not just for the specific dataset I am interested in (i.e. HYCOM).
In reading the GDS User Guide, this is apparently the expected
behavior. Is there no way to access an XML catalog for a single GDS
dataset and then feed this into TDS?
Cheers,
John
