How the W3C geo vocabulary is used

July 27th, 2006

longitude and latitudewgs84_pos is a very basic RDF vocabulary developed by the W3C to provide the Semantic Web community with a namespace for representing latitude, longitude and other information about spatially-located things. Geo is currently the 10th highest ranked vocabulary according to Swoogle’s special ontology ranking algorithm. Last month the W3C created a Geospatial Incubator Group, to begin addressing issues of location and geographical properties of resources, starting with a study of geo. Dan Brickley asked if we could use Swoogle to collect some data on how the geo vocabulary is being used. See this note for our attempt to answer his questions.
