Abstract
The paper proposes an approach to light-weight formal specification for interfaces, connectors, contracts and integration of component systems based on UML 2.0 superstructure. Both of static and dynamic contracts are provided with formal models. Dynamic contract can be verified through finding a legal environment in an optimistical way for the integrated components, whose contracts are depicted with interface protocol state machines. The consistency for component refinement is also studied. These formal models form the foundation for model checking, compositional reasoning, and real-time architecture development of component-based safety critical systems.
