Joern's other problem here is that the types used by dbpedia include 
things that are not covered by the dbpedia endpoint, i.e. opencyc, skos, 
etc.

Now he has to discover the sparql endpoint for these.

Luckily VOID + rkbexplorer has the solution for him:

Keith points out a more elegant (i.e. no specific webservice) solution, 
but it doesn't work everywhere: http://blogs.talis.com/n2/archives/914

Cheers,
