As for standard names, MMI established a set of URIs at
http://marinemetadata.org/cf
but has not been keeping up to date. I have written a XSL transform at
http://iridl.ldeo.columbia.edu/ontologies/xslt/.cfsn2rdf.xsl
that can be applied to
http://cf-pcmdi.llnl.gov/documents/cf-standard-names/standard-name-table/16/cf-standard-name-table.xml
to generate an up-to-date version, e.g.
xsltproc
http://iridl.ldeo.columbia.edu/ontologies/xslt/.cfsn2rdf.xsl
http://cf-pcmdi.llnl.gov/documents/cf-standard-names/standard-name-table/16/cf-standard-name-table.xml
On the other hand, Roy has created opaque URIs for standard names at
http://vocab.ndg.nerc.ac.uk/list/P07/9 contains all the Standard Names that

he changes them with each version, so it is both more definitive and harder
to use. It is also pure SKOS, so one needs to add structure to actually
connect it with a CF-described dataset. I plan to write out a map between
the two, so that I can use his relationships between CF standard_names, but
I do not have it yet.
Additional information and ontologies describing the CF structure both as
attributes and conceptually are available at
http://iridl.ldeo.columbia.edu/ontologies/, including the connections
between the standard_name ontologies and the CF structure.
