Saturday 23rd February is Open Data Day 2013! Open Data Day is a gathering of citizens in cities around the world 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.

The events are open to anyone: from curious citizens to journalists, tech-geeks to scientists, designers to data wranglers. Swing by on the day to hack, have a hangout and wrangle with us!

At the Open Knowledge Foundation we’ve been involved in Open Data Days since they started two years ago and this year will be no exception (we are also proud to be able to contribute to making Open Data Day happen by hosting the mailing list and website).

Around the World

There are Open Data Day events taking place all around the world.
We’re especially excited to see several members of the Open Knowledge Foundation network are organizing events – including ones in Vienna, London, Berlin and more – further details below!


We’ll be organizing an Open Data Day event in London. For full details, including information about sign up form and location, please go to our Open Data Day 2013 – London page.

Among other things we’ll be looking at PyBossa & the Crowdcrafting platform for creating citizen science apps, data wrangling some Natural Environment Research Council (NERC) open data, the Open Research Data Handbook, and the Open Data Census (see below).

We’ll end the day with a live link-up to Creative Commons, San Francisco to join with their Open Data Day activities.


Open Knowledge Foundation Germany are organizing a event focusing on a variety of projects, from the collaborative creation of a list of the 10 Hottest Datasets under the guidance of Michael Kreil from OpenDataCities to a Frag den Staat hackathon run by Stefan Wehrmeyer.
