The following post is from Jonathan Gray, Community Coordinator at the Open Knowledge Foundation.

This weekend developers all over the world will get together for a series of events as part of Random Hacks of Kindness, which aim to use “practical open technology to make the world a better place“. We imagine that many of the things that people will work on will build on open datasets from public bodies.

As Random Hacks of Kindness finishes on the evening of the 5th June, we thought we’d remind people that the Open Data Challenge also finishes on midnight on the 5th June (i.e. between 5th and 6th June). There are €20k worth of prizes for apps, ideas, datasets and visualisations. Any #RHoK developers based in Europe are eligible to enter!

  • If you’re not a developer, or don’t have time to build anything – you might nevertheless be interested in submitting an idea to the competition.

Also if you’re looking for open data to use as part of RHoK, you might be interested in having a look on, and on CKAN. If you get or clean up any datasets and want to share them – please do consider adding them on CKAN so others can find and build on your efforts!
