Hello Michael, others, With WRL we take an approach different from SWRL. We build on the experience in the Logic Programming and Deductive Database communities (and partially other rules communities) and (syntactically) restrict ourselves to Horn and add nonmonotonic negation, whereas SWRL stays within a First-order framework and simply extends the expressiveness of OWL DL. WRL extends a subset of OWL DL; this subset which falls in the framework of standard Horn rules.
