Collecting, processing, and distributing information has always been a core function of government. This core function has evolved from the earliest ancient governments using clay tablets to today's smart cities relying on integrated data exchanges (IDE). A smart city “uses information and information technology to make better decisions to improve the quality of life” (Nam and Pardo, 2011). The IDE framework builds upon the data platform literature (O'Reilly, Jan. 2011) by incorporating governance systems to manage a smart city's activities. This conceptual paper takes existing research, synthesizes it, and creates a new framework to identify how cities can select the appropriate governance rules to facilitate the political, financial, and operational sustainability of their IDEs, and derivatively, their smart city efforts.
