This project is investigating the use of HyTime for the purpose of supporting content-based or semantic navigation in a networked information environment. HyTime is a standard (ISO/IEC 10744:1992) for representing the structure of hypertext and multi-media documents. HyTime extends Standard Generalized Markup Language (SGML) with semantic extensions at the meta level. HyTime semantic links are roughly analogous to relationships that might appear in the schema of a conventional database. The investigation consists of four steps: (1) definition of HyTime links on real-world data, (2) assessment of the utility of HyTime links for content-based navigation, (3) construction of a simple prototype demonstration of HyTime on real-world data, and (4) initial consideration of the feasibility of integrating HyTime information with database data. The goal for this work is to provide semantic or content-based navigation for users of the National Information Infrastructure or similar networked-environment and to consider the potential for semantic links between the world of documents with the wmrld of database objects.

该项目正在研究在网络信息环境中使用HyTime来支持基于内容或语义的导航。HyTime是表示超文本和多媒体文档结构的标准（ISO/IEC 10744:1992）。HyTime通过元级别的语义扩展扩展了标准通用标记语言（SGML）。HyTime语义链接大致类似于传统数据库模式中可能出现的关系。研究包括四个步骤：(1)在真实数据上定义HyTime链接；(2)评估HyTime链接在基于内容的导航中的效用；(3)在真实数据上构建HyTime的简单原型演示；(4)初步考虑将HyTime信息与数据库数据集成的可行性。这项工作的目标是为国家信息基础设施或类似网络环境的用户提供语义或基于内容的导航，并考虑文档世界与数据库对象世界之间的语义链接的潜力。
