Hi, Yes, it is a simple sparql query, but quite heavy in performance. The public store is limited (I think result set size=1000 and max of 200 seconds). I always keep some ready images here: http://downloads.dbpedia.org/ see the tar.gzs, but haven't had the time to load 3.4 in our local mirror store. I can probably produce the numbers for 3.3 quite easily, as we have the data set loaded into a virtuoso here locally. If you want to do it yourself, you can use the query below and modify it a little bit. Regards, Sebastian, AKSW Select ?template ?property count(?property) as ?count From <http://dbpedia.org> { ?s <http://dbpedia.org/property/wikiPageUsesTemplate> ?template . ?s ?property ?o.
