                      } ,
                      { 
                        "ans" : {
                            "type" : "uri" ,

                          }
                      } ,
                      { 
                        "ans" : {
                            "type" : "uri" ,
                            "value" : "http://dbpedia.org/resource/Linlithgow_Palace"
