hello dbpedia developers, the main dbpedia frontend has recently (between september[1] and december) started having issues with articles with umlauts or other non-ascii characters in it.
requests like fetching data about Austria (Österreich) like
curl -H 'accept: text/turtle' -v http://dbpedia.org/resource/%C3%96sterreich
leading to
curl http://dbpedia.org/data/%C3%96sterreich.ttl
(which look encoded correctly as per [2], given that http can't
transport IRIs) give the following output lines modulo boilerplate:
<http://dbpedia.org/resource/%C3%96sterreich> owl:sameAs
<http://dbpedia.org/resource/%C3%96sterreich> .
<http://dbpedia.org/resource/%C3%96sterreich> owl:sameAs dbr:Österreich .
the first output line is tautological, but so what; the second is
important information as per [3], but following one's nose stops there
for lack of a way to dereference dbr:Österreich that was not already
tried.
this is especially impractical in foreign language wikipedias (german
dbpedia has been having issues on its own[1]), and areas where funny
characters can occur in titles like movies (eg. [4], [5]).
i failed to find the source of the dbpedia component that is acutually
serving the linked data; my suggestion is that it should serve the iri's
statements on the canonical (as per [2]) address. the two currently
shipped lines should probably stay to allow identification independent
of whether the application tried to fetch it as an IRI or a URI.
thanks for your work and your consideration
