[Pellet-users] APIs OWL

[Alan Ruttenberg]

I wanted to offer a clarification of my comment about incompleteness of the
JENA SPARQL implementation. There are two senses of "incomplete" - one wrt.
the implementation of SPARQL - JENA is complete, AFAIK, in this sense. It
isn't missing any SPARQL features.

The other sense is that of completeness with respect to returning OWL-DL
entailments in query results. This goes beyond the SPARQL specification, but
is of interest to those of use who use owl. In this sense, JENA will answer,
on its own, fewer entailed results than Pellet will.

Regards,
Alan
