The aim of our work is to propose a hybrid model allowing the representation of shared contexts. The originality of our approach is to propose a model of the environment where the agents evolve. We consider the environment as an active support of communication, which searches interested agents for each deposited message. We consider this environment as a shared context of work, which means that each transmitted message is available for all agents and each agent specifies the messages it is interested in, by writing a rule in its environment, thus allowing their reception. We present in this article the model of the proposed environment. We describe the characteristics of the agents and an adapted communication protocol. This model will be illustrated by an application coming from the field of public transport.
