Hi Benno,
That's a pretty thorough overview of the current position. One minor point is
that the URIs you give from my system serve version 9 - not the current
version. Replace the '9' by 'current' to get the latest version e.g.
<http://vocab.ndg.nerc.ac.uk/list/P071/9>
http://vocab.ndg.nerc.ac.uk/list/P071/<http://vocab.ndg.nerc.ac.uk/list/P071/current>current
.
Cheers, Roy.

Subject: Re: [CF-metadata] Web reference to a standard name?
We have tried to get standard URIs for CF concepts, but the effort bogged down.
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
have ever been published, including names that have been aliased
http://vocab.ndg.nerc.ac.uk/list/P071/9 contains the Standard Names that are
currently valid (i.e. those that have not been deprecated through aliasing)
http://vocab.ndg.nerc.ac.uk/list/P072/9 contains the Standard Names that have
been deprecated through aliasing
The mapping between deprecates and their replacement aliases my be obtained
through the following API call
http://vocab.ndg.nerc.ac.uk/axis2/services/vocab/getMap?subjectList=http://vocab.ndg.nerc.ac.uk/list/P072/current&predicate=255&objectList=http://vocab.ndg.nerc.ac.uk/list/P071/current&inference=false
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.
