Freie Universität Berlin has released DBpedia Mobile. Based on the current GPS position of a mobile device, DBpedia Mobile renders a map containing information about nearby locations from the DBpedia dataset (currently around 300,000 locations). DBpedia Mobile uses the Marbles Linked Data Browser to render Fresnel-based views for selected resources, as well as its SPARQL capabilities to build the map view. Starting from the map, users can explore background information about locations and can navigate into DBpedia and other interlinked datasets such as GeoNames, Revyu, EuroStat and Flickr.
More information about DBpedia Mobile is found on the project website.
