Property Restrictions
(Sub)classes can be created by restricting a property’s behaviour
on that class
Restriction may be by:
value constraints (i.e., further restrictions on the range)
all
values must be from a class
at least one
value must be from a class
cardinality constraints
(i.e., how many times the property can be used on an instance?)
minimum cardinality
maximum cardinality
exact cardinality
