What do I enter rather than 25 for max if is unlimited? Forgot to ask.

Is typically * or n but not sure which OWLReady2 accepts.

I am not sure but this adaption of your example might help:
https://nbviewer.jupyter.org/github/cknoll/demo-material/blob/main/expertise_system/cardinality_restriction_demo.ipynb


Main difference: Instead of just creating the restriction object by `has_Equipments.max(25, Equipment) ` it is now added to the list `EquipmentContainer.is_a` via `EquipmentContainer.is_a.append(has_Equipments.max(25, Equipment))`.

Actually, I set the max-value to 1 to simplify the test whether the reasoner detects an violation to this restriction. This works as expected.

The restriction also shows up in the XML-Code.

Note that I simplified the example by considering only one of the original four restrictions...


Best regards,
Carsten
