The rapid diffusion of service-oriented systems is becoming a reality in today's software engineering. In particular, an aspect that is gathering the interest of researchers and practitioners is the possibility to create compositions of dynamically bound services. This paper describes WS Binder, a framework for enabling dynamic binding of service compositions according to some functional and non-functional preferences and/or constraints. The framework is also able to support run-time recovery
