As you can see with this Meta Cartridge example [1] we do lookups and provide a VoiD description of the dynamically generated Linked Data Space. +1 for extending the language to incorporate VoiD so that other can loosely couple their efforts with ours, or simply build their own :-) Links: 1. http://linkeddata.uriburner.com/about/html/http://www.crunchbase.com/company/yahoo - a meshup across Crunchbase, Calais, Zemanta, and DBpedia.
