An approach to a reference model for a sentient smart city

The interest about Smart City concept has in creased in recent years. In fact, Smart Cities is ex pected to improve cityzens life experience by driv ing the next digital revolution, moving from the personal area (mobile computing, smart home) to the urban area (collective computing and collective intelligence). But the development of Smart Cities is not being as fast as expected. Several problems need to be undertaken in order to achieve the ob jectives of the paradigm. This paper presents an approach to address one of these problems: to or chestrate the platform that is required for gathering information about city, store it in a model and ena ble it for exploitation. The heterogeneity of the po tential data sources available and the complexity of the information nature and structure, make it a non trivial task that have to be solved before commer cial solutions appear and provide specific and non interoperable solutions.
