Here is the abstract:
This book is about the principles behind the open government data movement and its development in the United States. The movement is framed as the application of Big Data to civics, where Big Data is not just the size of data but the ability for data to change the way we understand its subject. Topics include principles of open government data, the history of the movement, applications to transparency and civic engagement, a brief legal history, data quality, civic hacking, and paradoxes in transparency.
This book is organized into chapters covering the movement and its history, examples and a typology of open government data applications, a brief legal history of open government data, principles and recommendations for creating open government data, and limitations in the use of data for government transparency. The appendix includes excerpts of open data policy language and model language.
The book includes substantial discussion of legal open government data and legislative information systems.
