I think what Helen Darbishire has done--and I heartily recommend her report--is point out that ten years ago the transparency community and the open data community were two very different bodies, but increasingly they're coming to work together. You can see this in the U.S. and the U.K.
One of the parts of freedom of information that people don't talk about much is the proactive aspect. When people discuss freedom of information and access to information they often talk about people making requests and responses. But proactive dissemination is contained in every act I know of, and it is as important. And it's hoped that technology can alleviate some of the problems around freedom of information.
Freedom of information can be seen as quite costly to bureaucracies in terms of time. It can be seen as quite complex, in the sense that the information isn't always easily understandable to everybody once it's put out there. And it's hoped that use of open data and information technology can both cut down costs and also make the information much simpler so that more and more people can understand it. So the hope is that open data can mean that FOI leaps ahead and becomes easier to use and much less costly and, as was pointed out earlier, you can do much more with the information once it's out there and it's combined with applications.
