An “interspheral interface” is that part of an interspheral system through which an exchange takes place between the parts of the system that lie in different spheres.

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”.
