To make the cities smart and sustainable, there is an urgent need for developing a stable information architecture which is interoperable, functional, extensible, palpable and transferable. Data infrastructure as part of this architecture covers the services for supporting dynamic data collected by various sensors in addition to a virtual district model, which models the physical district’s objects and can be enriched with semantic information. Open Geospatial Consortium (OGC) standards such as CityGML and Sensor Web Enablement (SWE) play an important role in the establishment of this model. In this paper a detailed description of this information architecture is given from the information viewpoint according to the standard ISO 10746 “Information technology – Open Distributed Processing- Reference model”.     «
