Hi David, the Free Edition only includes a single inference engine, for SPARQL Rules [1]. The default inference engine of Maestro is SwiftOWLIM, which is a rule-based OWL engine. If you want to get similar results as the OWLIM engine, you need to select a SPARQL Rule base containing the OWL RL rules. I recently blogged about this [2]. In your workspace, you will find a file owlrl-all.rdf, which you need to import into your model (drag and drop it into the Imports view). Then run inferences as usual. Note that in 3.4 this will be much easier and has been significantly improved and cleaned up. Note that depending on the OWLIM settings, the SPARQL Rules engine (TopSPIN) may return different results. If you have specific needs not covered by OWL RL, please let us know.
