Property restrictions in
OWL
-
Restriction may be by:
-
- value constraints (ie, further restrictions on the range)
-
-
all
values must be from a class (like the price
example)
-
some
value must be from a class
- cardinality constraints (ie, how many times the property is
used on an instance?)
-
- minimum cardinality
- maximum cardinality
- exact cardinality
