  We are in the process of building complex highly autonomous systems that have
build-in beliefs, perceive their environment and exchange information. These
systems construct their respective world view and based on it they plan their
future manoeuvres, i.e., they choose their actions in order to establish their
goals based on their prediction of the possible futures. Usually these systems
face an overwhelming flood of information provided by a variety of sources
where by far not everything is relevant. The goal of our work is to develop a
formal approach to determine what is relevant for a safety critical autonomous
system at its current mission, i.e., what information suffices to build an
appropriate world view to accomplish its mission goals.
