I second that thought.

Hi Dom
Actually, I think we really want:
http://cfconventions.org/something
(We own cfconventions.org, so we can point it where we want!)
And I would like in 2011 to have settled on a permanent answer to that
question!
Cheers

Thanks all,
Interesting to see the new MMI ontology work.
I take from this discussion then that there is not currently a CF
'blessed' method to reference a term?
E.g. for air_temperature I can choose from any of these:
http://mmisw.org/ont/cf/parameter/air_temperature
http://vocab.ndg.nerc.ac.uk/term/P071/16/CFSN0023
http://cf-pcmdi.llnl.gov/documents/cf-standard-names/standard-name-ta
ble/16/cf-standard-name-table.html#air_temperature plus:
http://cf-pcmdi.llnl.gov/documents/cf-standard-names/standard-name-ta
ble/16/cf-standard-name-table.xml
Cheers,
Dom

A minor clarification as to how MMI is doing things:

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.
Thanks for the mention. This is our older URL, sorry; we are now
maintaining CF standard names in our ontology repository, using
resolvable URLs. [1]
There was a period when MMI was not keeping up to date with CF
changes, but in the recent past we have been continuously updating
the SKOS ontology for the parameter names at the site Carlos
mentioned [1] (We will forward the misleading /cf URL above, or
fix it to make clear in some other way the current status; thanks
for calling that out.)
As with Roy's handling, we provide URLs both for the current
version at the reference URL, and for individual releases of the
vocabulary.

[1] http://mmisw.org/ont/cf/parameter
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&object
List=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.
