Bugs of owlready2 #27

Open AleSteB opened 11 months ago

AleSteB commented 11 months ago

When working with owlready2 some bugs/features arise, which I want to address here, maybe it helps someone, hope it is the right place to post.

With some ontologies, I get a stack overflow error during readin of the respective ontology using owlready2's get_ontology(URL).load()

This often is due to contained obsolete classes and deprecated object properties within the ontology file. My workaround is to manual delete the obsolete classes and object properties within the ontology file with Protégé and then saving the resulting file in rdf/xml as a local copy. Afterwards you can use get_ontology('./local_path_to_ontology/ontology_name.owl').load() to load the 'fixed' ontology.

the Owlready forum would also be a good place to share this
