The NSDL Central System

国家科学、数学、工程和技术教育数字图书馆（NSDL）计划的目标是改变科学、数学、工程和技术教育和知识共享。由此产生的国家数字图书馆不仅应提供传统的图书馆服务，还应鼓励新的学习、合作和资源传播方法。这个项目是建立一个为期一年的数字图书馆核心集成组件的原型，它提供了技术基础设施、标准和指南，整合了不同的馆藏和服务，以及管理设施的组织框架。PI和团队参与的合作为项目贡献了多种技术和专业知识。Dienst体系结构在包括网络计算机科学技术参考图书馆（NCSTRL）在内的许多分布式数字图书馆应用中已被证明是有效的，它构成了该项目的技术基础，并为多个层次的参与提供了框架，包括那些由开放档案倡议协议（基于Dienst协议）定义的参与。项目人员在元数据倡议和研究中持续发挥领导作用，如都柏林核心和沃里克框架，正在促进NSDL元数据标准的发展和整合。康奈尔大学图书馆在开发、完善和管理康奈尔大学图书馆门户方面的经验提供了许可、组织和管理数字资源方面的专业知识。最后，项目团队在数字图书馆研究社区中的高水平参与正在加速关键技术的转移。

The objective of the National Science, Mathematics, Engineering, and Technology Education Digital Library (NSDL) Program is to transform science, mathematics, engineering, and technology education and knowledge sharing. The resulting national digital library should not only provide traditional library services, but also encourage new methods of learning, collaboration, and dissemination of resources. This project is building a one-year prototype of the core integrating component of the digital library, that provides a technical infrastructure, standards and guidelines, integration of diverse collections and services, and an organizational framework for the management of the facility. Collaborations on which the PI and team are involved are contributing several technologies and expertise to the project. The Dienst architecture, which has proven effective in a number of distributed digital library applications including the Networked Computer Science Technical Reference Library (NCSTRL), forms the technical foundation for the project, and provides a framework for multiple levels of participation including those defined by the agreements of the Open Archives initiative (which are based on the Dienst protocol). The ongoing leadership role of project staff in metadata initiatives and research, such as the Dublin Core and Warwick Framework, is facilitating the development and incorporation of NSDL metadata standards. The experience of the University Library in developing, refining, and managing the Cornell University Library Gateway provides expertise in licensing, organizing, and managing digital resources. Finally, the project team's high-level of participation in the digital library research community is accelerating crucial technology transfer.
