Hi Dimitris, I am afraid that you did not completely see my point. It is not simply a redirection problem. For example, if I want to make a SPARQL query -- what is the birth date of the architect who designed the Brooklyn Bridge?
PREFIX dbo: <http://dbpedia.org/ontology/> SELECT ?person, ?date WHERE { :Brooklyn_Bridge dbo:architect ?person . ?person dbo:birthDate ?date . } It should be able to return the correct answer. However, there is no result. The problem is caused by the redirection. I am curious that even the Wikipedia article doesn't use the redirection. Why does the corresponding DBpedia article use it?
