Compositionality provides the foundation of software modularity, re-usability and separate verification of software components. One of the known difficulties, when separately verifying components, is producing compositional proofs for progress properties of distributed systems. This paper offers a UNITY-based framework to model distributed applications which are built with a component based approach. The framework enables components to be abstractly specified in terms of contracts. Temporal properties are expressed and proven in the UNITY style. Compositional reasoning about components’ properties, including progress, is supported. The semantical model is simple and intuitive.
