Figure 5.3 presents our constraint metamodel. The main
new concepts and attributes added to our feature metamodel
are the following:
- GroupConstraint . It allows us to create constraints
including group features;
- Constraint . It allows us to create constraints including
solitary or grouped features;
- fineMin and fineMax attributes. They allow us to relate
the cardinality property to constraints;
- OCLExpression . It represents the structural dependency
property of constraints;
- Metaconcept . It represents metaconcepts related to
constraints.
