Try: <http://dbpedia.org/page/Orange_%28fruit%29> 1/ "(" and ")" aren't allowed in URIs, nor in prefixed names. Browsers kindly encode them into %28 and %29 For example: go to http://dbpedia.org/page/Orange_(fruit) with Firefox and then cut and paste the contents of the URL bar into a text editor. You get %28-%29 (in FF 3.6 at least) 2/ This is an encoding, not an escape sequence - the URIs really do have "%-2-8" and "%-2-9" in them. 3/ SPARQL does not allow % in a prefixed name so you'll have to use WHERE {<http://dbpedia.org/page/Orange_%28fruit%29> ?p ?o . } or BASE <http://dbpedia.org/page/> SELECT ?p ?o WHERE { <Orange_%28fruit%29> ?p ?o . } The fact that <http://dbpedia.org/page/Orange_(fruit)> works is more luck than anything else :-) Andy On 24/06/2010 12:08, Buikstra, A.P.F. wrote: > Hi, > > My question is straightforward, but I didn't find it through Google.
