These RDF graphs represent the concepts used in the OpenStreetMap dataset.
The RDF datasets contained in this folder have been extracted by 
the OpenStreetMap Wiki Crawler 
(http://github.com/ucd-spatial/OsmWikiCrawler).
The semantic network is represented as a SKOS vocabulary 
(see http://www.w3.org/2004/02/skos), validated using the service
http://demo.semantic-web.at:8080/SkosServices
