Research on Component Composition with Formal Semantics

Formal semantics of components are foundations for rigorous analyzing and reasoning about the composition process and its correctness. According to the notion of software contract, components interaction patterns and composition process patterns, formal semantics of components are proposed. With this basis and inspired by typing system and process construction methods of -calculus, a typing framework for the composition are proposed. Additionally, based on the operational semantics, a formal model of component is suggested. Then, transition rules about component composition are introduced based on the -calculus typing rules. At last, the feasibility and validity of the proposed composition method are confirmed by the results of composition experiments on a composition platform FSCC.
