A metamodeling platform for augmented reality (AR) and virtual reality (VR) has been developed and has been used even if it is still under development. On this platform, a scene type represents a (layer of a) modeling language. Here are four layers representing modeling of an IT infrastructure at different levels of abstraction. Each layer is described with a JSON file and can contain in these cases classes, relationclasses, ports and attributes. The metamodeling platform allows to create models based on implementation of the scene types and allows to use these models with AR and VR.
