AOKell is a Java implementation of the Fractal component model which uses Aspect-Oriented Programming. The goal of AOKell is to provide some high level mechanisms for implementing the control semantics of a Fractal component.

The two main contributions of AOKell are to provide:

* an aspect-oriented solution for gluing the control part of a Fractal component with its content, * a component-based solution for implementing the control part of a Fractal component.

AOKell is then a framework where the notions of a component, an interface, and a binding are used both to implement the business part of an application and its control semantics. The novelty is thus to provide a component-based engineering of control.This control part is then glued to the content using either AspectJ aspects or Spoon processors.
