[Rdfapi-php-interest] Named concepts

Hi everybody, I'm using RAP api in order to access RDF resources and I've
also took a look at powl project. I'm using the POWLStore model (an extended
dbModel) and I've used some methods like listTopClasses (powl function) in
order to view my ontology classes, but I feel like something is missing. I'm
using the classical w3c wine ontology but I'm not able to list all the
concepts, like the method getNamedConcepts() in Jena api. Is there a similar
function in RAP/powl?

Thanks a lot.
