This document discusses open data, open innovation, and how the cloud can enable them. It provides examples of governments and organizations that have successfully used open data and the cloud to create valuable applications and services at low cost. Releasing data in an open format through the cloud allows developers to build innovative apps, provides new services to citizens, and can stimulate economic growth through data reuse and new businesses. Studies show the economic benefits of open data initiatives often significantly outweigh the costs of making the data publicly available.
