What we're talking about is a new form of copyright that's designed for sharing. It's really designed for the Internet. It's designed for these kinds of data sets. It's called Creative Commons. There's a movement behind it to revitalize copyright to make it easier to understand and easier to share. It's easier to remix and have different kinds of uses that are past the very simple traditional view of copyright that mostly exists today.
