When traveling and visiting new places, tourists are mobile as they wander around and follow tours through cities and landscapes. Location-based mobile systems today typically provide and deliver the the same information to all users which however does not necessarily meet the individual user's needs. In the presented approach, we aim to address the limitations of mobile devices, the unreliability of the network, and the different user's interest for the selection and the delivery of multimedia information to mobile devices. For this, a modular platform for mobile location-aware applications and a software framework for the generation of personalized multimedia content are integrated. Our sample application shows how the approach can provide a generic application support that allows the generation of mobile location-based personalized multimedia content in the domain of travel and tourism.
