Someone at your link, in the comments (edit: just realised that it's you), claims the Crown Copyright means re-use is reliant on a revocable licence. Is that true? How can that be compatible with Creative Commons as they suggest here:<p><a href="http://data.gov.uk/terms-conditions/" rel="nofollow">http://data.gov.uk/terms-conditions/</a><p>I'm a bit more worried by "you must ensure that you do not distort, mutilate, modify or take other derogatory action in relation to the information".<p>I don't even want them to restrict <i>distortions</i>, <i>mutilations</i> or <i>derogatory actions</i> (whatever the hell that might mean in relation to the location of public loos, or government spending figures). However, "ensure you do not ... <i>modify</i> ... the information" seems to defeat the whole purpose of the project.
