I want to ask Lorenz, about the Then part of the rule: THEN -> team FavoriteLeague is FACup
FACup is the resource in my owl (just followed Create Instance tab in Protege and Protege has give it the default URI like other resources in the file). Before we execute the rule, is it must that we should declare it in Java code like we do in Jena class before using it in Rules like OntClass team = model.getOntClass(ns + "Team") Because I am sure the problem lies in the resource FACup (or its URI).
