Control-driven coordination based assembling of components

The coordination paradigm has been used extensively as a mechanism for software composition and integration. Consequently, a number of associated models and languages have been proposed which address issues of CBSE from the coordination point of view. In this paper we use the control-driven approach to coordination and we present a framework within which it is possible to assemble components written in contemporary programming environments. In particular, we show how the coordination model IWIM, advocating a black-box approach to component development, can be realized in ActiveX. We map the fundamental building blocks of the IWIM model to ActiveX controls and we then show by means of an example the applicability of our approach, presenting also the results in a visual way, thus taking advantage of the features offered by the ActiveX environment.
