 Traditionally when we exchange information we first try to know as much as possible about each other’s systems. We carefully examine each other’s data objects so that we know what they mean, and to exploit fortunate idiosyncrasies. We think we are being smart, and of course we are, but the cost is that we are forever locked into the particular software versions of the applications at each end of the exchange; if we change anything the information exchange may break.
