The Information Medium

The paper offers the foundations of the theory of information media. Information media are dynamical systems with additional macro-structure of information-carrying states and information preserving transformations. The paper also defines the notion of information media network, as a system of information media connected by information transformations. It is demonstrated that many standard examples of information containing and processing systems are captured by the general notion of information medium. The paper uses the theory (and informal discussion) of information media to motivate a structural approach to the information in media. The idea is that the notion of information transformation should be regarded as more primitive than the notion of informational state. Thus in information systems, especially in the context of information technology, information is secondary, information transformation is primary.
