Hello,

I would like to write my own ontology.
For some properties I would like to restrict their range to URIs or
BlankNodes but to forbid literals.
For example:
myprop a rdf:Property ;
            rdfs:range ***URIs or BlankNodes*** .

I have difficulties to understand some semantics of RDFS and OWL.
I don't see a way to do what I want with pure RDFS.
I have read about owl:Thing but I don't understand what it is supposed to
mean.
Is owl:Thing the range I am looking for ?
Is it possible to do what I need after all ?

Thanks for your help.

Jeremy
