Abstract
Service-oriented computing is becoming the prominent paradigm for leveraging inter-enterprise information systems to complete higher-order business transactions at the heart of the modus operandi of the virtual enterprise (VE). This paper describes research aimed at supporting the formation and operations of virtual enterprises through the setting-up of service-oriented workspace environments. The paper argues that a role-based authorization approach to service invocation is necessary in order to enhance and guarantee the integrity of the transactions that take place in the business environment of a VE. The core components of the architecture are described supported by a proof of concept demonstrator evaluated in real organizational contexts.
