Person = model.Type("Person")
Pet = model.Type("Pet")

with model.rule():
    # Add a person named Alice with two pets.
    alice = Person.add(name="Alice")
    alice.pets.extend([
        Pet.add(name="Fluffy", type="cat"),
        Pet.add(name="Spot", type="dog")
    ])

# The 'pets' property of the Person type is multi-valued.
