RDF Ontology for getMap requests?

We expose an RDF ontology to the sematic web. Some of our ontology terms correspond to polygons in a WMS service that we host.

For instance, to get the polygon for OWL named individual http://biodiversity.org.au/voc/afd/Term#region.ibra.BRT, you would

  • use the wms server at http://biodiversity.org.au/geoserver/wms
  • use layer topp:ibra61_reg_shape
  • use an xml filter


Is there a standard way to say this in RDF? Or will I have to make my own little vocabulary to do it? I have aked google about ontologies for geo data, but it has not been terribly helpful so far.
