Figure 4. Model composition process in Alloy. 4.1 Defining Input Figure 5 presents a simple meta-model for class diagrams in Figure 1, defined in Alloy. It defines an Element, which has two sets of properties — those that are associated with it using composite associations and using shared associations. An Element can specialize at most one other element. In this meta- model, multiple specializations are not allowed. In addition, the meta-model defines two generic elements — LeftElement and RightElenent, which are used as a base for all elements of the first and the second input model, respectively. Both LeftElement and RightElement extend the generic Element type.
