Programming task packages: Peach exchange format

Programming education and contests have introduced software to help evaluation by executing submitted taskwork. We present the notion of a task package as a unit for collecting, storing, archiving, and exchanging all information concerning a programming task. We also describe a specific format for such task packages as used in our system Peach, and illustrate it with an example. Our goal is to stimulate the development of an international standard for packaging of programming tasks.
