w3c sparql test cases(approve sites)

Here are some of my own:

States in Austria

 SELECT * WHERE {
   ?c state ?state .
   ?c country Austria .
 }

Titles, Authors,

This...

 PREFIX dc: <http://purl.org/dc/elements/1.1/>(approve sites)
 SELECT ?book ?title ?authorname
 WHERE {
 ?book dc:creator ?author .
 ?author dc:type <http ://hoppa.com/Painters/> .
      ?author dc:title ?authorname .
      ?book dc:title ?title .
 }

Buildings with defined # of floors:

snorql query

 SELECT *
 WHERE { 
  ?building dbpedia2:building_name ?name .
  ?building dbpedia2:height_stories ?stories .
 }

This produces a surprisingly short list.

This...

 SELECT *
 WHERE { 
   ?building dbpedia2:building_name ?name .
   ?building dbpedia2:height_stories ?stories .
 }

Shows all the named buildings. Or this shows all buildings in NYC, and shows where the missing # floors are. This could be used to QA and update the data in Wikipedia to improve it (as well as dbpedia). snorql query

 SELECT *
 WHERE { 
   ?building dbpedia2:building_name ?name .
   ?building dbpedia2:location ?location .
   OPTIONAL { ?building dbpedia2:height_stories ?stories }

   FILTER regex(?location, "York", "i")

}

Language-specific queries

How to get sparql queries to return results in a specific language
