The UK government has launched a competition to encourage programmers to tap into the gigabytes of government information by building mashup applications.
A £20,000 prize fund to develop the best ideas to the next level is up for grabs.
"A crack team of data ferrets working for the task force have returned from their first forays into the bowels of government. Data available includes neighbourhood statistics (NeSS) data and healthcare services and information from the NHS," says the competition website.
Examples of mashups already using public data include a crime mapping application that enables users to see what crimes have happened in their local area, FixMyStreet, which enables the public to report problems in their street, and RateMyPrison.
The Power of Information Taskforce is running the competition on the government's behalf.
