Hi Tayfun, Thank you so much!
That way only works if I choose a model without any class-hierarchy inference. Of course. When I'm working with a model with class-hierarchy inference (e.g. OWL_MEM_TRANS_INF ou a reasoner) can I still get the direct Disjointwith classes ?? I tried it getting them using the baseModel but the "as(OntClass.class)" part doesn't work. If there isn't any other way...I'm doomed to load 2x my ontology... it is not good :) Any ideas ?
