Are you interested in using open data for good in Europe? The Open Data Challenge is designed to encourage interesting ways of reusing public data for the benefit of European citizens.  The competition encourages anyone from programmers to non-technical idea-makers to help create a useful app using public data.

Do you have a great idea? Here's how you can get involved:

• Ideas – Anyone can suggest an idea for projects which reuse public information to do something interesting or useful.
• Apps – Teams of developers can submit working applications which reuse public information.
• Visualisations – Designers, artists and others can submit interesting or insightful visual representations of public information.
• Datasets - Public bodies can submit newly opened up datasets, or developers can submit derived datasets which they've cleaned up, or linked together

The Open Data Challenge is open between now and June 5. Enter your ideas to win one of several cash prizes!
