Abstract

Along with the increase in users' demands for service functions, single services or simple functions cannot satisfy users' requirements any more. Therefore, we need service composition to provide customized services or compound functions to meet users' needs. However, existing methods cannot describe customized services or guarantee the safety of service composition, so we propose a novel framework for service description and operations in this paper. Our framework is composed of a new format for service description and a set of service operations. The former is used to describe the structure of customized services and to be the foundation of service operations, while the latter is used to represents the dependency relationships between services and to verify the safety of service composition. Compared to the existing service description languages, our method can be used to describe customized services and to be the basis for achieving the automation of service composition. An example is given to demonstrate that our approach can provide better service description and safe service composition.
