We've been thinking about this some with our vocabulary mappings in the THREDDS catalog spec. I know we've looked at the mapping between GRIB variables and CF standard names. It might be good to think about mappings between standard keywords as well.Hi Ethan, Nice document!I would say that we also add another item in the "Things to Think about": the mapping among the different standard vocabularies: "CF", "GCMD", "ADN", and "SWEET", etc..
And let me suggest too, the need to create unique ids for vocabularies. That way we can mapped them and better discover datasets. Not only using String matching, but by using explicit crosswalks among them. Better if the id is a URI.
I added all of this to the "Things to Think About" section Thanks, Ethan
Luis Begin forwarded message:-----Original Message----- From: Ethan Davis [mailto:address@hidden] Hi all, We've been working on drafting a document for a netCDF attributeconvention to help facilitate dataset discovery. The attributes parallelthe "digital library metadata" defined in the THREDDS catalog specification (http://www.unidata.ucar.edu/projects/THREDDS/tech/catalog/InvCatalogSpec.html). The attributes will be used by THREDDS tools to extract metadata from datasets and export to Dublin Core, DIF, ADN, FGDC, ISO 19115, etc. Here's the link to the document: http://www.unidata.ucar.edu/packages/netcdf-java/formats/DataDiscoveryAttConvention.html We would appreciate your thoughts and comments.
