Data coming from the public sector create a significant value for the digital economy (data-driven economy), because they constitute a direct element of digital products and services, but also increasingly serve as a resource for training artificial intelligence models. Legal provisions, to varying degrees, allow entrepreneurs to access and exploit these data. Three phases in the evolution of these provisions and another three phases of users’ (entrepreneurs’) information rights should be distinguished: 1) access to public information, 2) re-use of public sector information and data opening, 3) re-use of certain categories of protected data. The last two phases constitute a direct response to entrepreneurs’ demand not only for access to the information itself, but also for the establishment of conditions for its permissible exploitation for economic purposes. In our national context, what remains necessary is an understanding of their importance for the growth of a data-driven economy.
