Ubiquitous Information Systems (ISs) should support mobility of users and reason efficiently on their context to provide relevant and real-time information. ISs should be particularly adaptive and context-aware by managing and responding properly to occurring events. A need of integrating an adaptive and distributed event based system raises to lead to a diversity of proposed approaches and architectures. Unfortunately, the high level link between context and events is not explicitly considered in these systems. In this paper, we propose a metamodel coupling context and event metadata. The metamodel highlights some requirements considered in the definition of an event processing architecture to maximize communication security between distributed components. Context-aware event processing is a natural result of such architecture enabling the integration of context reasoning in event based systems. The proposal is used to implement an assistant prototype for passengers in the public transportation domain.
