摘　　要：现有的软件复用技术通常是围绕着库来组织利用标准的和通用的可复用资源．例如，面向对象编程环境中的类库和通用构件库．然而，这种以库为中心的复用方式在一定程度上忽略了可复用资源的项目相关信息，而项目相关信息记录了可复用资源的应用语境（ＡｐｐｌｉｃａｔｉｏｎＣｏｎｔｅｘｔ）．应用语境有利于可复用资源的理解和使用．为此，提出了一种围绕着一个项目的文档来组织和利用可复用资源的复用途径，即以项目为中心的文档复用，用以支持在相同应用领域中一族软件的开发．探讨了当前的面向对象方法在支持文档复用方面的一些局限性，提出了一种增强文档的方案．针对文档中可复用资源的浏览和维护。Current software reuse techniques usually utilize a repository to organize standard and generic reusable assets, such as class libraries and generic component repository in objectoriented programming environments. However, this repositorycentered reuse ignores the project related information to some extent, which describes application context of reusable assets. Application context is useful to the understanding and utilization of the assets. In this paper, an alternative objectoriented reuse approach is presented, which utilizes the documentation of a project to organize reusable assets. This socalled projectcentered documentation reuse is very useful to the development of a family of software in the same domain. In the paper, some limitations of current objectoriented methods for supporting documentation reuse are discussed and a new method for enhancing documentation for reuse is provided and analyzed. Then, aiming at browsing and maintaining reusable assets in documentation, the needs for navigation in documents are discussed and enumerated.
