Re: Proposed netCDF attribute convention for dataset discovery

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..

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.

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

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
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:
