Open Data in Los Angeles Office of the Controller.

Position:Cover story

The current controller for the City of Los Angeles, California, was elected in 2013 with the goal of reimagining local government through transparency, technology, and transformation. He immediately started working toward opening the books on the city's finances by creating an open data portal, ControlPanel LA, which provides information on the city's expenses, revenues, budget, and more.

When the open data platform was launched, in December 2013, the mayor issued an executive directive promoting transparency and accountability for the City of Los Angeles, making raw data publicly available in easy-to-find and accessible formats.
