How to know what restrictions have been applied to a class

[Neha]

Hello,

Can we figure out what restrictions apply to a class or if any restrictions have been applied to a class with owlready2?

Hi,

Restriction are considered as superclass in OWL, so they are listed in Class.is_a and Class.equivalent_to.

Then, you can use isinstance to test whether a given superclass is a class (isinstance(superclass, EntityClass)), a Restriction (isinstance(superclass, Restriction)), or more generally a construct (isinstance(superclass, Construct)), etc.
