OpenDataPhilly is the source for open data in the Philadelphia region. It is a data portal that provides access to more than 300 data sets, applications, and APIs related to the region. Built by Azavea, a Philadelphia-based geospatial software firm, OpenDataPhilly is based on the idea that providing free and easy access to digital information encourages better and more transparent government and a more engaged and knowledgeable citizenry.
OpenDataPhilly differs from most municipal government open data portals. OpenDataPhilly is supported and maintained by a community that includes the City of Philadelphia, Temple University, Azavea, and other organizations. The relaunch underscores a commitment to open source software, as well, as it is built on the Comprehensive Knowledge Archive Network (CKAN).
OpenDataPhilly was primarily a pro bono project by Azavea with additional funding from the William Penn Foundation and the Knight Foundation. It first launched during Philly Tech Week in April 2011, and was relaunched in February 2015.
