模型转换是模型驱动开发的核心操作，它通常被实现成一种特殊的程序。模型转换可以实现不同模型、模型和代码，以及模型和各种结构化文档之间的转换。随着模型驱动方法的发展，模型转换正在被运用到越来越复杂的问题上，从而导致越来越庞大的规模和越来越复杂的程序结构。为了更好地控制转换开发过程中的复杂性，需要一种图形化的建模语言，支持对转换程序的分析和设计。提出一种针对模型转换程序的可视化建模语言VisTML（the visual transformation modeling language）。它包含7种不同的视图，每个视图都包含一组建模概念。这些概念覆盖了整个转换程序开发过程中（从需求到部署运行）的所有主要阶段，支持开发人员在不同的抽象层次基于不同视角刻画模型转换。用VisTML对转换程序进行建模，有助于控制其复杂性，并促进开发人员的相互沟通与分工合作。最后介绍了VisT M L的支持工具T M odeler ，并且通过3个案例论证VisT M L的可行性与有效性。

Model transformations ,the core operations within model‐driven development ,are usually realized as special kinds of programs .They can be used to achieve diverse conversions among models , codes ,and even structural documents .With the rapid progress in model‐driven methodology ,model transformations are being applied to more and more complicated problems in industrial projects .As a result ,they become large in scale and have complex structures .To handle the development complexity of large transformation ,a graphical modeling language that can serve as a user‐friendly notation for analyzing and designing transformations is required . This paper proposes VisTML (the visual transformation modeling language) ,a visual modeling language for model transformation programs . VisTML is comprised by seven diagrams , including goal diagram , transformation declaration diagram ,model type diagram ,rule diagram ,composite transformation diagram ,testing diagram ,and configuration diagram ,each of which includes a set of concepts derived from concrete transformation technologies .VisT M L is able to cover all the major phases w hen a transformation is being developed . It supports developers to describe a transformation from various viewpoints at different abstraction level .Modeling a transformation using VisTML can help developers control the complexity and facilitate their communication .Then ,the tool support of VisTML named TModeler is also presented . At last ,three case studies are presented to demonstrate the feasibility and the effectiveness of VisTML .
