Existing systems have demonstrated the structured document representation's usability and usefulness. The representation's continued importance is insured by its inclusion in the ISO SGML Draft International Standard (8879). Recent research has developed user interfaces for manipulating structured documents that incorporate a grammatical definition of their component's interrelationships. As this user interface design shifts from research to development, it is appropriate to more closely examine the strengths and weaknesses of the representation. Two aspects will be investigated. The first is how the activities of cooperating authors can be aided in an environment supporting such a representation. Such authors may be interacting with separate computers that are only loosely-coupled--perhaps over an intermittent, low-bandwidth link. An important part of this portion of the project will be the development of mechanisms that permit repartitioning of the already structured document. The second aspect is the degree to which the specification of a line- oriented drawing can be isolated from the context in which the drawing is displayed. A strength of the structured document is the degree of such isolation with textual material. This portion of the research is directed to developing a model of line drawings that permits a similar isolation from the display context.

现有的系统已经证明了结构化文档 代表性的可用性和有用性。 代表性的 将其纳入ISO SGML草案，确保了其持续的重要性 国际标准（8879）。 最近的研究开发了用户 用于操纵结构化文档的接口， 语法定义其组件的相互关系。 作为 这种用户界面设计从研究转向开发， 适当的，以更密切地审查的长处和弱点， 表示. 将研究两个方面。 第一个问题是， 合作作者可以在支持这样的环境中得到帮助， 表示. 这些作者可能与单独的 松散耦合的计算机--也许是间歇性的， 低带宽链路。 这个项目的一个重要部分是 将是发展机制，允许重新划分的 已经结构化的文件。 第二个方面是一条线的规格- 定向绘图可以从绘图的上下文中分离出来， 显示。 结构化文档的强度是 这种与文本材料的隔离。 这部分研究是 致力于开发一种线条画模型， 与显示上下文隔离。
