[Pellet-users] SPARQL pellet query and rdfs:label

[Paolo Bussotti]

Hi everybody,
I'm writing a software which is devised to exchange a URI (of class, 
propertties, individuals..) of the ontology  for their rdfs:label, 
possibly under the request of a xml:lang , in order to provide a 
multilingustic GUI for the knowledge-based system under development.
Apart from the programmatical approach, I would like to make use of 
SPARQL queries, in particular on the Pellet query engine (I'm using 
pellet-1.4RC2). However
I didn't manage to query for rdfs:label or rdfs:comment. Are they 
supported (or going to be) by the Pellet query engine. Or shall I use a 
particular form (which I ignore) must be used for queries about  those 
annotation properties?    
Many, many thanks in advance.
