An Archival Digital Libraries Repository

越来越多的人类知识正以文件、数据库和网页的形式以电子方式存储。不幸的是，随着技术和组织的发展，大多数数据存储并不是为在很长时间内保存信息而设计的。此外，信息往往以不协调和不整合的方式存储。这可能会导致智力记录的重要组成部分丢失。该项目的目标是设计和实现一个现代化的、可扩展的数字图书馆存储库(DLR)。DLR为其客户提供管理知识产权、保护信息、支付特许权使用费、会计和从其他来源输入信息的各种服务。DLR采用可扩展的分布式体系结构(从数十到数千GB，以及数十到数百个站点)；允许自治组织协作建立共享存储库；并将文档保存数百年或更长时间。目前涉及的研究主题包括：在分布式和不断变化的环境中识别数字对象；复制用于存档的数字对象；元数据的管理；分布式索引机制；以及稳健和可扩展的认识计划。这项研究将深入了解可用于存储库的选项，以及它们相关的性能、成本、功能和可用性。这一结果可能会影响未来图书馆和组织存储和组织数字信息的方式，导致不同类型的信息得到更好的结构、根据知识产权法进行管理并可供后代使用的存储库。Http://www-db.stanford.edu/archivalrep/

More and more human knowledge is being stored electronically, in the form of files, databases and Web pages. Unfortunately, most data stores are not designed for preserving information over very long periods of time, as technologies and organizations evolve. Furthermore, the information is often stored in an un-coordinated and un-integrated fashion. This can lead to the loss of important components of the intellectual record. The goal of this project is to design and implement a modern, scalable digital library repository (DLR). The DLR offers its clients a variety of services for managing intellectual property, for safeguarding information, for payment of royalties, for accounting, and for importing information from other sources. The DLR employs a scalable and distributed architecture (ranging from tens to thousands of gigabytes, and tens to hundreds of sites); allows autonomous organizations to collaborate in setting up a shared repository; and preserves documents for hundreds of years or more. Research topics currently addressed include the identification of digital objects in a distributed and changing environment; the replication of digital objects for archiving; the management of metadata; distributed indexing mechanisms; and robust and scalable awareness schemes. This research will yield insights into the options available for repositories, and their associated performance, cost, functionality, and usability. The results may impact the ways libraries and organizations store and organize digital information in the future, leading to repositories where information of different types is better structured, managed in accordance to intellectual property laws, and available for future generations. http://www-db.stanford.edu/archivalrep/
