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.

现有系统已经证明了结构化文档表示的可用性和实用性。 该表示法被纳入 ISO SGML 国际标准草案 (8879)，从而保证了它的持续重要性。 最近的研究开发了用于操作结构化文档的用户界面，其中包含其组件相互关系的语法定义。 随着用户界面设计从研究转向开发，更仔细地检查表示的优点和缺点是适当的。 将调查两个方面。 第一个是如何在支持这种表示的环境中帮助合作作者的活动。 这些作者可能正在与仅松散耦合的单独计算机进行交互——可能通过间歇性的低带宽链接。 该项目这一部分的一个重要部分将是开发允许对已经结构化的文档进行重新分区的机制。 第二个方面是面向线的绘图的规范可以与显示绘图的上下文隔离的程度。 结构化文档的优势在于与文本材料的隔离程度。 这部分研究旨在开发一种线条图模型，该模型允许与显示环境进行类似的隔离。
