The Guardian Datastore is an excellent resource, where editors source and collate data (often as Google docs spreadsheets), which readers can then use to create their own mashups and visualizations. Amongst other things, they currently have the latest data on MP’s expenses, world booze consumption and two centuries of bio diversity data from Wicken Fen in Cambridgeshire.
Guardian editor-in-chief Alan Rusbriger explains why data and the Guardian Datastore matters.
Also, the Guardian Datastore is running a competition for:
1) The best user experience for understanding meaning in data, and
2) The best tool for web developers to build other things with data.
It’s worth pointing out that the Guardian Datastore is relatively new, and there are some issues, however, I think it’s a great step in the right direction, and another example of why the Guardian leads the way with it’s transition to digital. (Open, hackable platforms, two way media, Clay Shirky, etc.)
