The OSM Semantic Network
================================================================================
Project home page:
http://wiki.openstreetmap.org/wiki/OSMSemanticNetwork
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
This data is derived from information collected by OpenStreetMap
(http://www.openstreetmap.org) and licensed under the same terms as the OSM
data, currently the Creative Commons Attribution-ShareAlike 2.0 license.
RDF is a standard Semantic Web format: http://www.w3.org/RDF
The files were validated with http://www.w3.org/RDF/Validator
