An interoperable Open Specifications Framework for Smart City urban platforms

Global acceptance and demand for urban digitization to solve current and future ecological and socio-economic challenges is increasing. Technically, the Smart City concept integrates different vertical domains and uses an Open Standardized Urban Platform (OSUP) as a horizontal integration layer. In this sense, urban platforms play an important role in the digitisation process with the objective of creating more environmentally friendly cities. They face several questions like which ICT architecture to rely on, ensure interoperability, avoid vendor lock in... However, usage of open standards is still a gap regarding interoperability, which is a key concept in urban data platforms. Hence, the present paper describes an Open Specifications Framework, based on global open standards as enabler of urban platform developments under the interoperability and openness concepts. This framework is defined in the scope of the mySMARTLife project (GA #731297) and its deployment is carried out in three cities: Nantes, Hamburg and Helsinki.
