Keywords: conceptual modelling, multi-channel, web services, web operations, context, UML, OCL

Web services are progressively becoming multi-channel and cross-channel. The "same" service should be made available in different delivery environments and devices. A user may invoke a service on one device, suspend it, and complete its execution in another one. In this paper we present MC2 a design framework for Multi/Cross Channel web services adopting a high-level, end user perspective and exploiting the notion of context, to characterize who, where and how an operation can be invoked.
