Web services have the potential to serve as a key enabling technology for environments facilitating collaborative scenarios. This paper analyzes a same room/same time collaborative scenario, a program committee (PC) meeting. The focus is on design and implementation of a service-oriented approach for PC meetings. The proposed solution includes various Web services for the actual support of the work, Web applications combining those services, and presence-aware technology, in this case RFID (Radio Frequency Identification) tags. The contribution of this paper is to show how a presence-aware infrastructure comprising Web services and RFID technology can be built and how they provide support for the envisaged scenario.
