    abstract = {For many practical learning scenarios, the integrated use of more than one learning tool is educationally beneficial. In these cases, interoperability between learning tools -- getting the pieces to talk -- is a crucial requirement that is often hard to achieve. This paper describes an architecture that aims at the integration of independent learning tools into one collaborative learning scenario. },
