Hi all!
Is there any way to access to a public virtuoso SPARQL end point
(e.g. http://dbpedia.org/sparql or http://demo.openlinksw.com) via
JDBC ? (same as when accessing to it locally)
Something like:
Class.forName("virtuoso.jdbc3.Driver");
con = DriverManager.getConnection("jdbc:virtuoso://DBpedia.org/UID=dba/
PWD=dba");
Do you really want SQL acces? Or you want to use SPARQL from Java?
For the latter case, what you are looking for is the Sesame API for
RDF. More specifically, take a look at AliBaba which provides an API
atop SPARQL HTTP.
Aldo,
Yes, but SPASQL over HTTP is much much faster if JDBC is the entry point.
We'll soon open up a SQL channel since WebID based Data Source Names
(ODBC, JDBC etc..) are all possible re. Virtuoso.
We just enable Virtuoso to accept WebID authenticated connections,
solely, via SQL port :-)
Of course, the AliBaba option is fine if JDBC rather than SPASQL (SPARQL
via JDBC based SQL connection) is the goal.

Many thanks!
