Hello Dominic and all,
MMI maintains an SKOS-based representation of the CF standard names at the
MMI Ontology Registry and Repository (ORR):
http://mmisw.org/ont/cf/parameter
In your browser, this URL will open the ontology in the ORR Portal. You can
click the Versions button to see a history of the versions we have at the
ORR. You can use content negotiation or an extension to request a
particular format, eg:
http://mmisw.org/ont/cf/parameter.rdf
http://mmisw.org/ont/cf/parameter.n3
You can find more details about the SKOS representation, mappings, Web
resolution of terms, and SPARQL queries involving the CF ontology at:
http://marinemetadata.org/orrcf . We would appreciate much any feedback to
improve this service and the documentation.
Best regards,
Carlos
