Derek; Are there any properties defined defined in your .owl file.
Also have a look at the -Schema.owl file to see what classes and
properties are defined.  If you want to sent the -Mapping and -Schema
files, I might be able to give you some things to try.  If you're
getting absolutely nothing, then there may be a problem with D2RQ
being able to get data from the Oracle database.

Longer term, I'll see what I can do about getting an example Oracle
database online.
