Examining the documentation in Apache at http://incubator.apache.org/jena/documentation/ I noticed that existing discussion in sourceforge is missing ( http://jena.sourceforge.net/DB/creating-db-models.html)
The apache documentation does discuss connectivity to Database under the SDB http://incubator.apache.org/jena/documentation/sdb/ yet it is not clear to me if both sourceforge and apache are consistent ? thanks, Aviad
