Offener Haushalt [offenerhaushalt.de] (German for 'open household budget') is another demonstration of the large potential behind the emerging Open Data phenomenon. Based on data that was harvested by the extensive 'screen scraping' of the website of the Bundesfinanzministerium (the German equivalent to the U.S. Department of the Treasury, but I simply had to include this word), Offener Haushalt attempts to open up socially relevant data to allow open and shared analysis, interpretation and discussion. Unfortunately, like most other European governments today, the German 'Bundesfinanzministerium' does not make open, machine-readable datasets available for download yet.

While still in an early 'beta', the online platform allows for the exploration (as 'specific categories', as 'groups' or as 'functions'), and commenting of the acquired data in a treemap structure, while each detail view is stored under individual and shareable URLs. The original sources are clearly mentioned, while the data can be downloaded in JSon, RDF or XML formats. In the meantime, the developers are calling anyone with valuable German data to come forward.

Actually, "Haushalt" is German for "budget".

thanks for the friendly mention of offenerhaushalt.de - I just have to spam a bit: the site's visualization is really basic now and we're looking for infovis people to help us improve the display and to incorporate federal income as well as spending.

So if anyone's looking for an evening project, we'd be more than happy to team up!

Nice! It can only be decades now until the german government release the data themselves. (I don't have much hope though, petitioning Google Street View seems to be way more important than transparency)

Well done! Democracy needs fresh tools like that!
