Nowadays, who controls the data, controls the world or at least the IT world. Usually Data are managed through a middleware, but in this project, we propose a new data paradigm without any data manager. We want to endow the data with autonomous behaviors and thus create a new entity, so-called Self-managed data. We plan to develop a distributed and autonomous environment, that we call SKYDATA, where the data are regulated by themselves. This change of paradigm represents a huge and truly innovative challenge! This goal must be built on the foundation of a strong theoretical study and knowledge on autonomic computing, since Self-managed data will now have to obtain and compute the services they need in autonomy. We also plan to actually develop a SKYDATA framework prototype and a green-IT use case that focuses data energy coonsumption. SKYDATA will be compliant with GDPR through the targeted datas and some internal process.
