What do you mean by the phrase: "that links two classes using a
predicate"? The only predicate I see that you have linking classes is
the subClassOf between AdventitousRoot and owl:Thing, and the
subClassOf between AdventitousRoot and the restriction.

The RDF that you've shown in your example will go into Jena just fine.
Indeed, you mentioned that it went in, and you even showed the
internal blank node identifier that Jena generated for the Restriction
class. So what is failing for you?
