One of the most interesting and sort of revolutionary parts of open data going forward with our colleagues in the U.S. and the U.K. is around new technologies that allow for the anonymization of data. I can say without hesitation that there's no personal data of any kind in any of the data sets that have been made available. Right now, when we're going out to individual departments to look for data, there can't be any personal data of any kind, not even a blip. But in the future, as we try to expand the amount of data being made available by a single department, we hope to be able to work with them to anonymize it so that it can still be made available.
