Hey Atanas, Thank you so much for your response. Basically we are looking to implement an application that automatedly generates OWL-DL Ontologies that have axioms, individuals and also make use a tableau reasoner, as well as store them in a repository. That being said I understand that SwiftOWLIM is one of the fastest reasoners out there, however; as you know it is not a full OWL-DL tableau reasoner and cannot deduce things such as disjointness. That being said we are looking for an OWL API (OO Style would be nice) that is complete in the sense that it will allow for the CRD of "complete" OWL-DL KBs. I think "The OWL API at http://owlapi.sourceforge.net/"; is just what the doctor ordered, has anyone here used the API is it any good (easy to use, somewhat complete, well documented, supported)?
