There's a lot of really great linked data stuff going on in classical studies. The Pelagios project (http://pelagios-project.blogspot.com/) is one of the best examples because the bar for participation is set very low. The RDF model is very simple, linking objects (works of literature, sculpture, papyri, coins, whatever) represented at URIs to URIs for places defined in the Pleiades Gazetteer of Ancient Places ( http://pleiades.stoa.org/), enabling aggregation of content based on geography.
