First, N3 is a RDF notation, so when you use N3, you actually use RDF.


> Is the above possible using RDF *only*? 

No, you need RDF and an inference Engine and the Engine will take some
syntax, the syntax may be OWL or DAML/OIL.  or a new engine with new
syntax you create (heavy work).


You didn't talk much about the framework you used, rdfdb and squish and
so, 
I really want to point you to 
http://www.hpl.hp.com/semweb/jena.htm

and the corresponding web server
http://www.hpl.hp.com/semweb/joseki.htm

These have all you want, especially the web interface of joseki is fine.

try out the Jena 2 preview 4 release because the Jena 2.0 release will
be in a month.

For inference engine there is an example how to use it at my wiki:
http://jena.gnowsis.com/wiki/pmwiki/Main/InferenceWithFileGraphDirty

this is a bit ugly and does not run, but unzip this:
http://jena.gnowsis.com/wiki/uploads/Main/InferenceWithFileGraphDirty.zi
p
anyway and have a look at the code.


You will probably end up using Jena because there is no other framework
that does as much as jena.

have a look at rdfgateway though, and also forth:
