Kristian,
Ah, okay -- I didn't realize you wanted specifically THREDDS metadata. To
enable search across multiple THREDDS catalogs (as well as other OGC and
community services) , we've be avoiding the direct use of THREDDS metadata
in favor of the ncISO metadata, which we then harvest using GI-CAT or
GeoPortal Server. An application can query GI-CAT or Geoportal Server
using OpenSearch or CSW, and then process the DAP data URLS matching the
query constraints.
Is this similar to what you are trying to do?
Thanks,
Rich
