RDFMapper is a web service that searches an RDF file for resources with geographic locations, and returns a map overlayed with dots representing located resources. Clicking on a dot displays a web page representing the clicked resource. Arbitrary images can be treated as maps, so the service can be used for any kind of image annotation. The parameters to the web service specify what RDF file is to be mapped, what basemap (eg of San Francisco or the world) is to appear in the background, how to extract the relevant data from an RDF resource for mapping, and how to generate the web page describing the resource. Geographic data may be expressed in several ways, including the RDFIG Geo vocabulary, and the combined use of the Dublin Core and RDFGeom2d vocabularies.
