Figure 2 also shows cardinality constraints. These are not part of the unconstrained class model. Later we will define constrained class models (Definition 4). However,
The cardinality constraints in Fig. 2 impose restrictions on object models. For example, a ticket corresponds to precisely one concert
Instead, we assume a given set VOM of valid object models satisfying all requirements (including cardinality constraints.
Relþ VOM satisfies all (cardinality) constraints including the following general requirements: for any ðr, mapk1, mapk2þ Rel there exist c1, c2, mapa1,
Moreover, all cardinality constraints are satisfied if OM VOM. Definition 4 abstracts from the concrete realization of object
Note that events may have varying cardinalities, e g.,, one event may create five objects of the same class.
The cardinality describes the cardinal number of node sets which are being matched to each other. A sample of a node matching with both 1: 1 and M:
