Hack de Overheid

Hack de Overheid ('hack the government') is a one day event that brings civil servants together with coders to discuss Open Data issues, as well as build applications during the day.


Most initiatives in the Netherlands, as well as data sources and mash-ups are driven bottom-up. Some departments are actively experimenting with open gov data (Ministry for the Interior, Min for Education). The approach is network driven (connecting and supporting change agents).

Dat zou handig zijn!

A Dutch competition for generating ideas around the reuse of public government data modelled after Show Us a Better Way in the UK. Launched May 2009, running until September 2009. 'Dat zou handig zijn' means 'That would be great to have'. The Ministry for the Interior has made 20.000 Euro available to help realize the best idea(s).

The competition generated 60 ideas. Winners were announced November 26th 2009.
Winning idea was 'where do my taxes go', which won funding to realize the idea. Runners up were two related ideas about garbage removal dates, and places to bring garbage.

This Dutch mash-up is based on PM10 data (particulate matter <10mg) from the Dutch national institute for environment RIVM. It takes the data and builds a smog forecast as well as historic record for each of the RIVM's sensors. Data is stored in Google App Engine.

This Dutch mash-up provides human readable information about schools, found based on ZIP-codes in the Netherlands. Page Detail
