Fractal is a modular and extensible component model that can be used with various programming languages to design, implement, deploy and reconfigure various systems and applications, from operating systems to middleware platforms and to graphical user interfaces. The goal of Fractal is to reduce the development, deployment and maintenance costs of software systems in general, and of OW2 projects in particular. The Fractal model already uses some well known design patterns, such as separation of interface and implementation and, more generally, separation of concerns, in order to achieve this goal. There is also ongoing research work to get even closer to this goal. Fractal is hosted and developed by the OW2 consortium. It is distributed under the LGPL open-source license. ==Sub Projects== The Fractal Project is made of four sub projects: * The Component Model sub project deals with the definition of the Fractal component model specification. The main characteristics of this model are recursivity (components can be nested in composite components - hence the "Fractal" name) and reflexivity (components have full introspection and intercession capabilities). The Fractal model is also language independent, and fully modular and extensible. * The Implementations sub project deals with the implementation of Fractal component platforms, which allow the creation, configuration and reconfiguration of Fractal components. Julia, the reference implementation, is developed in this sub project. * The Component Libraries sub project deals with the implementation of reusable, ready to use Fractal components, such as protocol or Swing components. * The Tools sub project deals with the implementation of Fractal based applications dedicated to Fractal, such as tools to define and manage component configurations . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fractal component model」の詳細全文を読む スポンサード リンク
