Web Service = E + F + I

This paper presents the E, F, I approach for the development of a contextual definition of a Web service. E, F, and I stand for environment, feature, and interaction, respectively. By default, a Web service resides in an environment E where it acts and reacts. In this environment E, the Web service exposes its features F to peers or other components for awareness and visibility purposes. Finally, the Web service gets engaged with peers in common activities by coordinating their interactions I. The contextual definition of a Web service is established using the components that make up each dimension of the E, F, I approach
