All,
To get the Jena RDF/XML-ABBREV syntax, I run some queries through Jena.
I need to set define sql:describe-mode "SPO" and also the default graph URI,
and for the SPARQL endpoint, this is trivially done by setting
DB.DBA.SYS_SPARQL_HOST, and that works great.
But how do I set it when using JDBC?
I have tried to pass defines from the code, e.g.:
sparql = QueryFactory.create(
"define sql:describe-mode \"SPO\"\n" +
"define input:default-graph-uri " + defaultGraph
+ " \n" +
req.getParameterValues("query")[0]);
but that seems to cause Jena to croak and say the query is invalid.
Then, the question is of course whether using JDBC gives me much? I could just
use the endpoint and then parse and reserialise the result, but that seems
wasteful.
Kind regards
Kjetil Kjernsmo
