Hi Ben and Jon,

In the last 2 weeks I have worked on the WCS 2.0 extension for CF-netCDF3.0. The first part of the specification introduces a new (and refined) version of the CF-netCDF3 data model mapping to ISO 19123.

Ben, in my opinion that part could be an excerpt of the OGC CF-netCDF specification.


The second part of the document, defines the CF-netCDF3 data model mapping to the GML-Coverage profile used for the WCS 2.0.


Presently, I am working on the WCS 2.0 service model extension.

Hi Jon,

It's a bit out of date now, but Stefano developed a UML diagram for CF in an ESIN article which maps the Unidata Common Data Model to the ISO 19123 Coverage specification:

S. Nativi, J. Caron, B. Domenico, L. Bigagli, "Unidata's Common Data Model Mapping to the ISO 19123 Data Model", Earth Sci Inform DOI 10.1007/s12145-008-0011-6, Springer-Verlag 2008.

 It's available online in pdf at:

<http://www.springerlink.com/content/t5g828928v82n6ju/fulltext.pdf>http://www.springerlink.com/content/t5g828928v82n6ju/fulltext.pdf

and html

I know Stefano has worked on that diagram in the intervening years, so I'll send him a copy of this note to see if he recommends a more recent version of the diagram.

Ah, I found it soon after I'd sent the email!  The one I'm thinking of
is in Nativi et al 2008 (DOI 10.1007/s12145-008-0011-6).  I think there
may be other ways of expressing the CF data model though (and I think
there are some small mistakes in the Nativi et al rendering).  Has
anyone produced any alternative representations?

Subject: [CF-metadata] UML for CF data model?

Hi all,

Has anyone produced a UML diagram describing the CF data model (as
distinct from the NetCDF data model)?  I seem to remember seeing one
somewhere, but I can't remember where...

Thanks,
Jon
