Sophie - a Conceptual Model for a Semantic Choreography Framework

Choreography models the external visible behavior of services as a set of message exchanges that realize Message Exchange Patterns (MEP). A number of language exist that try to tackle the problem. However they constitute incomplete solutions, either because they lack of support of semantics, have a tight relation to the underlying communication framework, or mix structural, behavioral and operational aspects resulting in confusing specifications. This position paper defines a conceptual model for SOPHIE, a choreography engine for Semantic Web Services following a Semantic Service-Oriented Architecture. The conceptual model of SOPHIE is especially suitable for supporting the fine grained interaction among services with different structural, behavioral or operational models. A case study in the Telecommunication sector is presented.
