DLI-2: Security and Reliability in Component-based Digital Libraries

在数字信息出现之前，对信息完整性的关注是许多机构的职责，其中包括研究图书馆、出版商和法律的当局。数字时代的一个主要挑战，也是创建数字图书馆的关键，是建立确保信息完整性的新机制和管理这些机制的新方法。信息完整性有三个主要特征：1）可靠性，它保证信息在人们需要的时候和地点都能得到。2)安全，既保护信息用户的隐私权，也保护内容创作者的知识产权; 3）保存，确保知识内容的寿命，供后代使用。 如果不能建立这些系统，将不可避免地威胁到所有依赖数字技术获取关键信息资源的机构--政府、企业、教育和国防--的生存能力。康奈尔大学数字图书馆项目将研究和开发数字图书馆体系结构的工作原型，特别关注支持这些完整性问题。该架构将建立在可重用组件的概念上，重点关注网络环境的关键现实和好处，全球分布，分布在多个管理实体之间的内容和服务的联合，以及扩展-新组件和功能可以添加到架构中以适应社区特定的要求或响应新技术。

Before the advent of digital information, attention to information integrity was the charge of a number of institutions - among them research libraries, publishers, and legal authorities. A major challenge in the digital age, and essential to the creation of digital libraries, is the creation of new mechanisms to ensure information integrity and new methods to administer those mechanisms. Information integrity, has three major characteristics:1) reliability, which ensures that information is available where and when people want it.; 2) security, which protects both the privacy rights of users of information and the intellectual property rights of content creators, and 3) preservation, which ensures the longevity of intellectual content for use by future generations. Failure to create these will inevitably threaten the viability of all institutions - government, business, education, and defense - that rely on digital technology for their mission-critical information resources.The Cornell Digital Library Project will investigate and develop working prototypes of a digital library architecture with particular attention to supporting these integrity issues. The architecture will build on the notion of reusable components, which focus on the critical realities and benefits of the networked environment, global distribution, federation of content and services distributed among multiple administrative entities, and extension where- new components and capabilities can be added to the architecture to suit community-specific requirements or in response to new technologies.
