Open Government has come a long way. The first wave of the open data movement continues to liberate data from closed formats and systems. The next wave is building an open infrastructure for collecting, managing, and publishing data in collaboration with citizens. This session aims to highlight the importance of building open tools and show where this field is moving to in the coming years. The panelists will draw on their rich experience to talk about the opportunities and challenges they've encountered in their work, giving the session a practical focus.
