IWR has been keeping an eye on the Free Our Data campaign which the Technology supplement of daily newspaper The Guardian has been running. We've been watching it and supporting it. Now Charles Arthur, editor of the Technology Guardian supplement, has asked IWR and its readers to join the campaign.

"The more people and organisations we have on board, the better our chances of success," he said. The campaign seeks to make data which the public has paid for freely available, which will then stimulate new information resources for information professionals and the public alike to use.

The campaign uses a blog as its central repository and communications point, so its easy for all of us to add more information to the cause. So if you know of examples of government information costing you or your organisation, despite having already paid for it once through your taxes, let the campaign know. "If everyone joins, it would be sort of hard for the government to ignore," Arthur adds.

The campaign, which has been running since 2006 ,has highlighted some interesting disparities in

Whitehall

's information policies. Ordnance Survey (OS), known for its maps has been revealed to charging British citizens repeatedly for geographic information that is already funded by the public purse. It has been revealed that local authorities pay the OS for map information during the planning application process, planning authorities also pay separately for the same map information. During the campaign it has been revealed that a total of eight separate payments arrive at the OS as part of a planning application.

There are bound to be many more cases like this and it would be great if Information World Review and its readers can be part of a campaign to make the information we already own more easily available.
