Thanks Dimitris - well done to the whole team. In case it helps anyone, I have brought up a sameAs store for the sameAs relations in this dataset alone: http://sameas.org/store/wikidata_dbpedia/ In passing, it is interesting to note that the example URI, http://wikidata.dbpedia.org/resource/Q586 , has 110 sameAs URIs in this dataset alone. What price now the old view that everybody would use the same URIs for Things?!
