The term “interspheral interface” was coined for the terminology of the “Digital Era Framework”. The “Digital Era Framework” serves as a frame of reference for the description of changes resulting from digital change, digitization and digital transformation. The framework enables a coherent depiction of the structures which characterize complex systems in a digital world. For this purpose, four spheres of information manifestation are distinguished: The infosphere, which consists of the analog infosphere and the digital infosphere, the cognisphere and the entisphere. If a system extends over several of these spheres, this constellation is referred to as the “interspheral system”.
