We report on our experiences in an e-government project for supporting the automatic generation of E-forms for services provided by local governments. The approach requires the integration of both the model-based user interface design (MBUID) and software product line engineering approaches. During the domain engineering activity the commonality and variability of product services is modeled using feature diagrams and the corresponding UI models are defined. To support the automation of e-forms the implemented feature models are on their turn used to generate E-forms automatically to enhance productivity, increase quality and reduce cost of development. We have developed three different approaches for e-form generation in increasing complexity: (1) offline model transformation without interaction (2) model transformation with initial interaction (3) model-transformation with run-time interaction. We discuss the lessons learned and propose a systematic approach for defining model transformations that is based on an interactive paradigm.

用于在电子政务项目上下文中生成电子表格的基于模型的用户界面设计

我们报告了我们在支持为地方政府提供的服务自动生成电子表格的电子政务项目中的经验。该方法需要集成基于模型的用户界面设计 (MBUID) 和软件产品线工程方法。在领域工程活动期间，产品服务的共性和可变性使用特征图进行建模，并定义相应的 UI 模型。为了支持电子表格的自动化，实施的特征模型轮流用于自动生成电子表格，以提高生产力、提高质量并降低开发成本。我们开发了三种不同的电子表格生成方法，其复杂性不断增加：(1) 没有交互的离线模型转换 (2) 具有初始交互的模型转换 (3) 具有运行时交互的模型转换。我们讨论了吸取的经验教训，并提出了一种定义基于交互范式的模型转换的系统方法。
