Abstract: Several techniques for using RDF to model change over time in a domain are reviewed and a new approach with a lower triple count than previous approaches is described. It is argued that the application programmer requires tool support so that she does not have to deal with the details of the modeling approach used. It is suggested that the quad is an appropriate programming abstraction that is independent of the modeling technique used and a quad based API for processing temporal RDF graphs is described. A technique for representing and implementing quad based queries within the current SPARQL syntax is also described. An implementation of this API is described along with a prototype of a real world application that has been constructed using it.
