This year’s International Open Data Day is happening on December 3rd. Citizens in cities around the world will be gathering to write applications, liberate data, create visualizations and publish analyses using open public data to show support for and encourage the adoption of open data policies by the world’s local, regional and national governments.
If you’re a software developer, designer, or visionary, check out an event near you. Here’s a short list of U.S. events:
Open data continues to gain traction around the world, with new open data catalogs launching in Europe, North America, and Africa in 2011, and more data than ever made available from organizations like the World Bank.
This weekend, hack something to make the world a better place.
