The call is growing louder for governments to embrace open data principles. The hope is that greater transparency will engage residents, increase accountability and spur new private uses of data. As a National Neighborhood Indicators Partnership member, Nonprofit Center of Milwaukee has long provided data for community use. The Milwaukee Data Initiative complements the Center's technical assistance work by creating a forum for researchers, data analysts, and developers to advocate for and promote the use of open data. Milwaukee's experience shows how the introduction of open data ideas can bring new energy for community data sharing and use.
