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. -- Scott On Oct 15, 7:56 am, Derek S <[EMAIL PROTECTED]> wrote: > Folks, > > I'm just starting with TBC.
