Dear all,
First of all I would like to thank you for maintaining this list.
I have a question regarding the necessity of using OWL query languages
when dealing with OWL DL ontologies.
SPARQL is a query language for RDF and it has been stated that OWL query
languages are needed so that queries take into account the semantics of
OWL. However, OWL semantics could be materialized by means of a
reasoner. So, couldn't we achieve the same with SPARQL in a Jena
environment for example?
Yes - you can but not for all of OWL-DL. For full OWL-DL, you use an external
reasoner (and that can be done and use the Jena API).
Jena inference documentation:

If I am wrong I would be extremely grateful if somebody could explain
this problem in depth using examples if possible.
Thank you in advance.
