Hi Hugh, thank you for your fast reply.
http://gfacet.semanticweb.org is working fine with http://dbpedia-live.openlinksw.com/sparql ! Are there any performance differences between http://dbpedia-live.openlinksw.com/sparql and http://dbpedia.org/sparql ? Otherwise, we will just use the live sparql endpoint permanently since the dataset is allways up to date.
