The development of information systems (IS) in the field of electrical engineering represents a significant challenge: virtual reality has to be explicit and remain true to the functional and behavioral perception of real industrial objects. The digitization of processes, names and functions is, in any case, not all that simple. One needs to study reality to understand the underlying cognitive representations. This paper presents two points that we feel are important: the denomination of computer objects in relation to their real-world correspondence and the functional representation within the IS.
