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). 2012/3/8 Rich Signell <rsignell@xxxxxxxx> > 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.
