OpenDataVote introduces itself with the line, "Vote to encourage your government to publish open data", and gives the following descriptive information:
In 2011, the OpenDataPhilly project team launched a public awareness campaign similar to OpenDataVote in order to encourage the City of Philadelphia to release more data sets that could potentially serve the nonprofit community. The effort was quite successful - it attracted more attention to the community-driven open data effort in Philadelphia and many of the nominated data sets have been released in the years since then.
A lot has changed since 2011. The City of Philadelphia now has a Chief Data Officer, open data is now part of the City’s policy, and there is an active staff supporting the initiative. Open Data Philly has grown from about 100 data sets to almost 350, and open data is being used in many locations across the region.
