Location-based systems are often aiming at the separation of the concept of location to a particular system, or, alternatively, treat location as yet another issue that should be fit into a larger prescribed application framework. This may lead to increasingly complex system architectures, when application logic uses location only as a facility. As a solution that gathers the best sides of both approaches, we propose an approach where object-oriented middleware is used for handling location-based issues in applications that run in mobile devices. In this paper, we will introduce distribution of software and hardware components, as well as sketch the internal architecture of the middleware in terms of the most relevant interfaces. Towards the end of the paper, a sample application is also introduced.
