Abstract: Until recently, the Internet was dominated by web sites and storefronts. We have now entered the next Internet evolution: e-services. E-services are modular, nimble, electronic services that perform work, achieve tasks, or complete transactions. The first step to turn an existing asset or service into an e-service revolves around accessibility. The virtualisation of the service provides communication channels that support automated conversational capabilities. The format of the service description allows automated discovery, and enables automated negotiation on contractual terms and parameters. The second step towards the realisation of the full potential for the e-service vision focuses instead on composition and interaction orchestration. Beyond business conversations for point interactions, e-services can expose complete interaction processes. A service delivery is no longer a one-to-one (buyer-to-seller) relationship, but it triggers the dynamic creation of business networks. In this document we first give a feeling about the e-service vision. We then propose a service model based on the ideas of functional incompleteness, multi-party orchestration, and dynamic service composition. A prototype based on the proposed model (DySCo).
