Hi --
I'm new to RDF and dbpedia. I'm trying to determine if I will be able
to use dbpedia in a project I am involved with.
The question I need a quick answer to is how many Places there are,
organized by language and location, as that has a bearing on whether we
may use dbpedia. It seems li
Thank you very much both of you! You were very helpful!

Hi Aliki,
As Olivier indicates the public DBpedia SPARQL endpoint is only accessible via
HTTP (port 80) so you have to use the jena “sparqlService” method to access it
with something like:
Query query = QueryFactory.create(sq);
QueryExecution qexec =
QueryExecutionFactory
The method I mentionned does not rely on any low-level Virtuoso
connection, nor wrapping it in a local Jena model.
It just connects to any SPARQL WebService (also called a SPARQL
endpoint) and sends the query
as an HTTP parameter. It retrieve the result data as XML, and wraps it
into a ResultSet ob
Thanks for the quick reply. The thing is I cannot connect to the server. If I
manage to connect, I will use the QueryExecutionFactory, I have already
downloaded the libraries. The line which we need to focus on is:
VirtGraph set = new VirtGraph
("jdbc:virtuoso://localhost:/charset=UTF-8/lo
What about:

Jena. So I would like to find a way to connect to the Virtuoso Server without
having to download all the data or install a Virtuoso Server on my pc.
If this is not possible, is there any other way/tool (ap
