Hi, I'm connecting to Virtuoso via virtjdbc4.jar (OpenLink Virtuoso(TM) Driver for JDBC(TM) Version 4.x [Build 3.57]) from RapidMiner 5.2.001.
I can access graphs using embedded SPARQL and that works ok if I hand-code the SQL but the integrated functions in RapidMiner have problems, they see DB/DBA/WS schema tables but only a subset of them and not any views that I create. I'm not at all sure that this is a Virtuoso problem but I am curious about why some tables are visible and not others. Is there anything that these tables have in common that would make them more accessible to a naive use of jdbc?
