problemns on example query at http://eurostat.linked-statistics.org#usage

[AxelPolleres]

1. the example SPARQL query at http://eurostat.linked-statistics.org/#usage doesn't have corrext SPARQL syntax, i.e.
   a) xsd: prefix is missing
   b) "xsd:decimal(?ghgtotal)_1000/(xsd:decimal(?population)) AS ?percapita"
   should be in parentheses, i.e.
   "(xsd:decimal(?ghgtotal)_1000/(xsd:decimal(?population)) AS ?percapita)"
2. the file referenced in the FROM clause of that query, i.e.
   http://semantic.eea.europa.eu/home/roug/eurostatdictionaries.rdf
   seems to be empty, at least I get an empty RDF when I retrieve it.
3. the following prefix URI in that query doesn't seem to be dereberencable
   PREFIX g: http://eurostat.linked-statistics.org/ontologies/geographic.rdf#
