Well, we're kind of in-between versions right now: we are completely 
redoing activerdf for 0.3, but that won't be ready for some time now.  

In the current version (0.2) blank nodes are not too difficult to hack, 
depending on your RDF store, but we did not find the time to do it yet (it 
was not important).  Such a hack is not a correct way to do it (doing it 
correctly is actually quite hard), but would work with some RDF stores.  So 
which RDF store are you using?  

Higher level support for OWL is not planned in the near future, but what 
exactly would you be looking for? It might be easy to add as an extension 
(by you or somebody else).
