The instance model is made up of objects and links that are based on the class model. Each object is an instance of a Class, Data Type, Interface or Signal defined in the class model and the links between objects that appear on Object Diagrams are instances of composite Aggregations defined in the class model between the corresponding Classes, Data Types, Interfaces and Signals.
