Location based services (LBS) and applications have recently emerged as a significant application area. However, location based services and application could also benefit of the dimensions of the contextual data. Multi-User Publishing Environment (MUPE) has a built-in context mediation capability that allows the application developer to concentrate on using contextual data and thus enabling rapid prototyping of location and context aware applications. In this paper MUPE context producers are applied so that the applications can exploit the different available context in a manner suitable to their logic. This paper purposes to demonstrate that context mediation is a powerful tool to speed up the prototyping process and to enable an efficient application development.
