Subject: Proposed netCDF attribute convention for dataset discovery

Hi all,

We've been working on drafting a document for a netCDF attribute
convention to help facilitate dataset discovery. The attributes parallel
the "digital library metadata" defined in the THREDDS catalog
specification
(http://www.unidata.ucar.edu/projects/THREDDS/tech/catalog/InvCatalogSpec.htm
l). 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:

ention.html

We would appreciate your thoughts and comments.

Thanks,

Ethan

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.

I added all of this to the "Things to Think About" section
Thanks,
Ethan
