Our data to be freed?
Rich sent me a link to this BBC story about evidence that the UK government's attitude towards data is changing. They have, “decided to make access to a database of UK laws completely free for the public to access and re-use.”
Let's hope that this is a harbinger of a more general change in attitude. The debate around Ordnance Survey mapping will continue for a long time, though there have been reports that OS are interested in opening up some way. The primary business of the Survey is to collect spatial data and produce maps. I have much less sympathy with government agencies which collect data in the line of fulfilling their statutory and tax-funded duty, yet still make obtaining access to that data difficult and time consuming (and therefore, indirectly, expensive) for academic researchers and impossible for the general public.
At the lauch event for the Intitution of Civil Engineers' report "Learning to live with rivers" report, commissioned by the government after the Autumn 2000 floods, I asked a representative of the Department for Environment, Food and Rural Affairs (Defra) (Defra) for a response to paragraph 11.11.1 of that report:
The Commission recommends that publicly collected primary and processed data (topographical, meteorological, hydrological and hydraulic) should be made publicly available, as is the case in the United States. This would result in improved flood risk assessment and management.
The gist of his response, as I remember it, was that without charging for data there was no way of knowing its value. This was some sort of official line, and he expressed a less hard-line view in private later. It occurs to me only now that this response is to some degree a red herring anyway: much of this data are available "free" to some, such as researchers on Defra or Environment Agency approved projects, and not at all to others. That point aside, the argument is redolent of accountant-driven policy. All one can establish by charging for data is its commercial value, and even that only crudely.
Blocking access to data (data, remember, which must be collected anyway), whether by charging for it or simply not making it available, destroys much of its value.
May the changes continue.
