Open data is data that can be freely used, re-used and redistributed by anyone - subject only, at most, to the requirement to attribute and sharealike.
Readers have already seen examples of the sorts of data that are or may become open - and they will see more examples below. However, it will be useful to quickly outline what sorts of data are, or could be, open – and, equally importantly, what won’t be open.
The key point is that when opening up data, the focus is on non-personal data, that is, data which does not contain information about specific individuals.
Similarly, for some kinds of government data, national security restrictions may apply.
