In terms of privacy, I think it's important to note that privacy is not just about releasing individual data, releasing the name of somebody and their medical status. Aggregate data actually can also release personal information. It's important that statisticians and so forth are very careful about the aggregate data, that you can't learn information about individuals from aggregate data. There are well-known cases of this where you can infer information about a public figure's medical records from the release of aggregate data. I think that's incredibly important in terms of privacy and what we release.
In terms of IP, I think there are very good open licences out there. Just as we have open licences for software, there are open licences for data that retain the IP on the information and let it be used for the public good. I think those licences are evolving still, but there is a good trend in those licences that lets you release your data while still maintaining ownership over that data. That's also an important point.
