A.: Seamless Engineering of Location-Aware Services

Abstract. In this paper we present a novel approach to design and implement applications that provide location-aware services. We show how a clear separation of design concerns (e.g. applicative, context-specific, etc) helps to improve modularity. We stress that by using dependency mechanism among outstanding components we can get rid of explicit rule-based approach thus simplifying evolution and maintenance. We first discuss some related work in this field. Next, we introduce a simple exemplary scenario and present the big picture of our architectural approach. Then we detail the process of service definition and activation. A discussion on communication and composition mechanisms is next presented and we end presenting some concluding remarks and further work.
