Combining third party software components to customer-individual application systems requires first, standardized specification techniques for describing the technical as well as the business-related aspects of the services provided and required by the corresponding software components and second, automated compatibility tests in order to identify components fulfilling demands specified by component requestors. Adequate techniques for the specification of component services are consolidated in a multilayered specification framework, where formal notations are preferred in order to enable the execution of automated compatibility tests. These tests are a prerequisite for the existence of component markets where third party software components are traded and components that fulfil the specified demands are identified. This paper presents an algorithm for the layer of the specification framework where coordination aspects of a software component are described. On this layer an extension o...
