Both educational and industrial institutions have a growing need to test experiments in highly complex, expensive structures. On the other hand, high-speed networking opens up the possibility of accessing remote sites and performing experiments with a high level of quality of service. The main goal of the LABNET (“ LABoratories on the NETwork” ) Project [1] was the realization of an Integrated Learning System that allows students and instructors, located in geographically dispersed areas, to access technological resources, such as sophisticated laboratory equipment, measurement devices and, in general, complex test systems, through a scalable networking infrastructure and a number of supporting multimedia technologies. The paper introduces a new perspective in the definition of a suitable interface to the instrumentation and proposes a web-service based instrument interface, as an evolution of the LABNET remote measurement framework.
