Hi Johannes, The the object in your where clause is an IRI not a literal , and thus should be specified with <..> rather than with double quotes " ..." , so the query should be:
PREFIX dbpprop: <http://dbpedia.org/property/> SELECT ?uri WHERE { ?uri dbpprop:wikipage-da <http://da.wikipedia.org/wiki/NATO> . } which returns subject uri <http://dbpedia.org/resource/NATO> Note you also need to ensure the graph name specified is http://da.dbpedia.org or not specify a default graph name at all such that all available graphs are queried (less optimal) ...
