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?


Best regards,
Lushan Han
