The development of the 4.0 revolution and the deployment of new technologies at the service of the information society and citizens in general, are gradually beginning to be accentuated within our reality, reaching the point of becoming a key part of the administrations' own exercise. However, for these to be effective, they must follow purposes set by governments. The first broad category of purpose is the improvement of public service, which itself includes technical and legal issues. It is by confronting these issues that open government and digital administration takes on a practical dimension and gives rise to much reflection. From a public law perspective, these processes should include administrative reforms that can be applied to the different branches of public power, developed through different legal instruments adapted to the proposed objectives.
