Hi Thomas,

I was looking at the query results page at:
http://vocabularies.unesco.org/sparql?default-graph-uri=&query=PREFIX+skos%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2004%2F02%2Fskos%2Fcore%23%3E+%0D%0APREFIX+isothes%3A+%3Chttp%3A%2F%2Fpurl.org%2Fiso25964%2Fskos-thes%23%3E%0D%0APREFIX+rdfs%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23%3E%0D%0APREFIX+dbo%3A+%3Chttp%3A%2F%2Fdbpedia.org%2Fontology%2F%3E%0D%0ASELECT+%3Fpays+%3FisoCode+%3Fconcept+%3FnomDbpedia%0D%0AWHERE+%7B%0D%0A%09SERVICE+%3Chttp%3A%2F%2Ffr.dbpedia.org%2Fsparql%3E+%7B%0D%0A++++%09%3Fpays+a+dbo%3ACountry+.%0D%0A++++%09%3Fpays+dbo%3AisoCodeRegion+%3FisoCode+.%0D%0A++++%09%3Fpays+rdfs%3Alabel+%3FnomDbpedia+.%0D%0A++++%09FILTER%28langMatches%28lang%28%3FnomDbpedia%29%2C+%27en%27%29%29%0D%0A++++%7D%0D%0A++++%3Fcollection+isothes%3AsuperGroup+%3Chttp%3A%2F%2Fvocabularies.unesco.org%2Fthesaurus%2Fdomain7%3E+.%0D%0A++++%3Fcollection+skos%3Amember+%3Fconcept+.%0D%0A++%09%3Fconcept+skos%3AprefLabel+%3FlabelThesaurus+.%0D%0A++++FILTER%28langMatches%28lang%28%3FlabelThesaurus%29%2C+%27en%27%29%29%0D%0A++++FILTER%28+UCASE%28STR%28%3FlabelThesaurus%29%29+%3D+UCASE%28STR%28%3FnomDbpedia%29%29+%29%0D%0A%7D+&format=application%2Fsparql-results%2Bxml&stylesheet=%2Fsparql-form%2Fxsl%2Fxml-to-html.xsl

Issue:

Links in the query results page aren't live i.e., I can't follow-my-nose
