This project investigates use of an additional layer of structure, called a meta-document, to organize decentralized network-accessible information, such as that found on the World-Wide Web. By developing meta-documents, documents whose components are themselves documents, discovered information can be placed into context and communicated to others. Consequently meta-documents hold promise of being useful in applications where information, created and maintained by others, needs to be transferred; educational applications at all levels have this characteristic. To make meta-documents effective, basic issues in information representation, presentation, personalization, structuring, location, and exploration are explored in this project. In addition, practical study is required of the means for authoring meta-documents and the means for keeping them in synchrony with the rapidly shifting contents of the Web. The resulting concepts have theoretical implications in understanding how to structure and communicate network-based digital information. They also have immediate practical application in producing materials that can be used in teaching and in providing overviews that will help the general public better identify relevant Web-based information on selected topics.http://www.csdl.tamu.edu/walden/

该项目研究使用称为元文档的附加结构层来组织分散的网络可访问信息，例如万维网上的信息。通过开发元文档（其组件本身就是文档的文档），可以将发现的信息放入上下文中并传达给其他人。因此，元文档有望在需要传输由他人创建和维护的信息的应用程序中发挥作用。各级教育应用都具有这一特点。为了使元文档有效，该项目探讨了信息表示、呈现、个性化、结构化、定位和探索方面的基本问题。此外，还需要对元文档的编写方法以及使元文档与快速变化的网络内容保持同步的方法进行实际研究。由此产生的概念对于理解如何构建和通信基于网络的数字信息具有理论意义。它们还可以直接用于制作可用于教学的材料和提供概述，从而帮助公众更好地识别选定主题的相关网络信息。http://www.csdl.tamu.edu/walden/
