Here are suggested verbalizations for the object cardinality constraint examples on p. 289, Fig. 22:
(a) The number of instances in the
population of JuryMember is 12.
(b) The number of instances in the
population of Senator is less than or equal to 100.
Here is a suggested, optimized verbalization for the role cardinality constraint example on p. 289, Fig. 22 (c):
At most one Employee is the director.
This role cardainality constraint pattern is the common case, so is worth optimizing. A more complex verbalization pattern is needed for the general case.
