Hello, I need to readout an existing ontology from a file. But I have a problem to readout the details of the restrictions of a class:

import owlready2 as or2
ontology = or2.get_ontology("file://sargon owl xml.owl").load()

for cla in ontology.classes():
      for restriction in cla.is_a:
            print(restriction)

The print gives an output like:
"sargon owl xml.hasFunction.some(sargon owl xml.StartStopFunction)"

But I don't know how to decompose this knowlegde into its seperate pieces (.property, .type , .cardinality and .value).

Calling e.g restriction.type resolves in "AttributeError: 'type' property is not defined".

Does someone know how I can access these informations?

Thank you in advance,
Lux
