So I was watching the MSU/Michigan game via ESPN's GameCast (not all games will have GameCast enabled), which is a pretty sexy interface if you don't have TV. Got me thinking about the data driving it. There's a lot of data ESPN must be typing into the backend in real-time. What format are they storing and transferring that data in? Naturally made me think of XML, and the possibility of an open interchange format for describing Football games.
