Bernhard,

Looks like a bug in Virtuoso. I guess a Turtle-ism crept into the N-
Triples serializer. As a workaround, you could try sending DBpedia RDF/ XML output through something like triplr.org to obtain valid N- Triples.

Best,
Richard

Hi,

I am retrieving data from dbpedia in N-TRIPLES format since my client
supports only this serialization format. However I wonder if the
output provided by dbpedia is invalid: for instance, when I issue the
query

DESCRIBE <http://dbpedia.org/resource/Vienna>

with header "Accept: text/plain" [1] the result contains the following
line:

<http://dbpedia.org/resource/Vienna> <http://dbpedia.org/property/ areaLandKm
        395.51 .

However according to [2] literals in N-triples must be encapsulated in
quotation marks.

[1] curl -H "Accept: text/plain" http://dbpedia.org/sparql? query=describe+dbpedia%3AVienna%0D%0A
[2] <http://www.w3.org/TR/rdf-testcases/#ntriples>

Is this a bug/problem in dbpedia or am I getting something wrong?

Thanks, and best regards
Bernhard
