From Digital to Ubiquitous Cities: Defining a Common Architecture for Urban Development

Digital cities have been evolved from web applications and knowledge bases to smart urban environments. This evolution has mainly been based on broadband metro-networks and complex information systems, and it suggests the form of the future city that is called wireless/smart/digital or ubiquitous city. Although common practices are being developed all over the world, different priorities are defined and different architectures are followed. In this paper we summarize on the applied architectures of multiple city case studies, we use the experiences of the digital city of Trikala, Greece, and we conclude to a common Enterprise Architecture for digital city cases. This common architecture identifies the blue prints for urban information based development. Moreover, this paper presents a common architecture for service delivery in urban spaces.
