Hi All,
Just in case anyone is interested. After further investigation I
discovered that a redirect from /resource/Companion_%28manga%29 to /
data/Companion_(manga).xml is taking place. The URL of the redirect,
which is unencoded returns an empty RDF document. However, a request
for the same encoded URL /data/Companion_%28manga%29.xml returns the
populated RDF. So, it appears to me that there is some issue with the
redirect and URL encoding.
Here is some relevant data from the traces I've done.

Hi,
Long time listener, first time poster.
Was wondering if anyone may have experienced the following behaviour
when attempting to fetch resource pages from dbpedia.org?
If I make a request with the following characteristics the RDF
document is returned as expected.
- URL: http://dbpedia.org/resource/Companion
- Type: GET
- Accept: application/rdf+xml
However when making a request with the following characteristics I
receive an empty RDF document
- URL: http://dbpedia.org/resource/Companion_%28caregiving%29 or
http://dbpedia.org/resource/Companion_(caregiving)
- Type: GET
- Accept:application/rdf+xml
The URL in the second case is referenced as a disambiguate of the
first, and if I view the same URL in a browser I get the redirect
to: http://dbpedia.org/page/Companion_(caregiving)
which contains some data which I would expect should be on the
resource page.
Of note, this just began happening sometime during the past few days,
prior to that I was able to fetch data from pages with round braces in
the URL. Anyone else seeing similar behaviour?
Thanks! Matthew
