Dear All,
Martin Schultz was proposing an extension to the Standard Name table to provide a means of easily identifying the Standard Names associated with a given atmospheric contaminant. What follows provides an alternative way to address his use case. Go to the URL
http://vocab.nerc.ac.uk/sparql/ and copy the SPARQL query at the end of this message into the box, choose your output format and press 'Get Results'. If you don't want 'carbon monoxide' simply replace 'Carbon monoxide' by another valid EEA contaminant name.
For the techies on the list, this is done by a federated SPARQL query involving SPARQL endpoints on vocabulary servers at BODC and the EEA. This is based on string matching, but could be made more robust by implementing an EEA/Standard Names mapping in NVS should this be requested by the CF community.
Cheers, Roy.
