Personally, when I tried D2RQ I had a some trouble with it and didn't like the mapping it produced. Another tool you can look at which I liked was the DataMaster plug-in in protégé. This works quite well and gives a decent OWL schema

I'm just lazy, and I'm trying to find the most automated way to get some quick but relevant RDF to experiment with Longwell. Thanks for the input.

I created the map by hand with a lot of trial and error, but Longwell loaded the resulting RDF just fine. Also, you may want to use the D2R live server if you want to skip the dumps, and just do SPARQL queries. I'm sure anything you CONSTRUCT into a file will be very importable. Hope it helps, it works like you would think, Thomas On 8/6/07, Ernest Martinez <[EMAIL PROTECTED]> wrote: > I'm trying to use Longwell in order to be able to perform faceted browsing > on data which is stored in a relational database (Oracle).
