S. 2852 would direct federal agencies to publish all data they collect in an open format that can be used by any computer. Under the bill, the Office of Management and Budget would establish an inventory of all federal data sets and would direct the General Services Administration to maintain an online interface for all such data. In addition, S. 2852 would rename the Office of Electronic Government as the Office of the Federal Chief Financial Officer.
Information from selected agencies suggest that most of the provisions of the bill would codify Executive Order 13642 and other executive branch policies that set the framework for agencies to promote openness and interoperability in information management. That executive order requires agencies to standardize data sets and to make them publicly available. A website (www.data.gov) has been established to share this government information with the general public. CBO expects that implementing S. 2852 would have no significant effect on spending because agencies effectively are already working to implement the requirements of the bill.
