Context management solutions aim to implement tasks related to dealing with context clearly separating them from those related to a system's features. An important issue in managing context is how to structure and represent it. We chose to represent context as a set of contextual elements and thus we are interested in defining a structure for those elements and their relation to context management dynamics. Generic context models are of interest since they can be reused by different applications and ease context sharing between systems. In this paper, we propose a generic context model that explicitly separates generic context concepts from specific concepts of an application domain. It is a top-down approach that can be reused as a base model on different context-sensitive systems.
