Re: Read all the subclasses of a class in case of multi-inheritance
Thank you all for your answers.
I reduced my code again and again and it seems OK now with a very small ontology. I think that there is something weird when I save the Protégé ontology. Sometimes it seems that the changes are not saved. So I'll look into Protégé rather than into Owlready.
Thanks again for your help and for this really nice library !
