Hi all,
my name is Andrea Di Menna (user: ninniuz) and I would like to
contribute to the en mappings project.
I am planning to use dbpedia data for a work project and would like to

Thank you very much,

As far as I can see the actors in the starring infobox property are

Ciao Amir,
As far as I understood the transitive option is a Virtuoso extension, that
means it is not defined in SPARQL 1.1 (used by Jena).
That means Jena will fail with a parser exception when trying to parse your
