Towards a Reference Model for Implementing the Fractal Specifications for Java and the .NET Platform

So far, several implementations of the Fractal specifications have been proposed. These implementations propose frameworks for programming with Fractal in a target language (Java, C, Smalltalk, C++). The general principles of implementing the specifications are common to all these frameworks. However, as far as we know, no concrete piece of software or no common set of internal interfaces have ever been shared between them. In this paper, we report on a reference model which has been set up to support several implementations on the Fractal Specifications. This model has been derived to build a Java personality called AOKell, and FractNet, a personality for the languages of the .NET framework. The originality of this model is to be based on the concepts of Aspect-Oriented Programming (AOP) [1]. Section 2 presents the general architecture of the reference architecture. Section 3 reports on the two personalities, AOKell and FractNet. Section 4 shows some performance measurements. Section 5 concludes this paper.
