The Avalon project is an effort to create, design, develop and maintain
a common framework and set of components for applications written
using the Java language. This framework is not a standalone product,
but allows existing and yet to be created applications to fit
into a common platform and to share code, design and human resources.

As many people point out, software engineering is a very uncommon procedure
in software development and even more uncommon in auto-organized open
source projects. The main goal of this project is to design a way for
different projects to share resources avoiding as much as possible efforts
duplication.

The Avalon Team are proud to announce a new whitepaper that covers how
to develop with Avalon. It covers the Framework, and touches on the
LogKit and Excalibur. You can find

The framework is not a product or an API set or a set of interfaces: it is
a collection of code design patterns, rules, guidelines and suggestions on how to
write software that "plugs" into the framework. The framework does not
impose restrictions on the application that uses it, but rather precious guidelines to
help the developers reuse as much work they can from other solutions.
