First Approximation to DHD Design and Implementation

Abstract

This work presents a proposal on design and implementation of web sites e-learning with
properties of service reconfiguration in execution time, offering a new adaptation and
personalisation mechanism with context-aware characteristics.
We describe an integration model to incorporate “the coordination context-aware contracts”
into an e-learning framework. The implementation has been solved using design patterns
which allow superimposition of rules through contracts, by means of the interaction between
the objects that implement services (i.e messages edition on a Forum) and the objects that
require them.
