Abstract
In this document we
present a Rapid Realization of Communication Services System (RRCommSSys).
RRCommSSys will be created using model driven software development techniques
in an easy to use graphical modeling framework, which will eventually allow us
to deploy a communications application employing the features already present
in the Skype and Smack API's. In particular we aim to provide audio
conversations including conference calling, real time texting and video
streaming within the education domain.
We present the
architecture, models and testing documentation of our system which includes a
User Communication Interface, a Synthesis Engine and a Network Communications
Broker. Using a Domain Specific Language (G-CML) we allow the user to create
their own communication schema instances by simply dragging and dropping
communication objects into a canvas. The system transforms this into executable
Java Function calls which delegate the details of the specific case to the
appropriate communications platform API.
