+This project is less about "data" than the others, and more about "open". Letten is a place at the Limmat river right behind the ZHdK building (where MakeOpenData is hosted) in Zürich, where lots of people like to swim.

-The project idea is described here:
+Daily temperature measurements taken at this exact location are readily available on the Web, but they are published in a hard to parse PDF document oriented towards  "scientific"  readers. This projects shows what is necessary to make use of the same data to answer the simple question "Should I go swimming today". Different visualizations are shown as a proof of concept. Finally a mashup connects the temperature to an LED to get a basic, physical "ambient notification".

 ===== Data =====
+First, the PDF data is parsed by HwPdfToPachube.exe, a rather complex C# program given the simple task of extracting the current temperature. IT took me 4 hours to write it. The data is then published to Pachube, a sensor platform based on open data formats. There might of course be other such platforms that could be used.

-Once the data is available in an open format it's quite easy to display it in  away that suits the consumer rather than the publisher of the data. While the original PDF contains a lot more information, the current temperature is what's most interesting if you're about to decide if you should go for a swim. There is no way for the government to cater to such needs as they might be very special or of concern to a small minority only. Data in an open format empowers such groups to take action themselves and use the data they paid for with tax money in a way that serves them well.
