The NSDL Central System

国家科学、数学、工程和技术教育数字图书馆(NSDL)计划的目标是转变科学、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该提供传统的图书馆服务，还应该鼓励新的学习、合作和传播资源的方法。该项目正在建立一个为期一年的数字图书馆核心整合部分的原型，提供技术基础设施、标准和准则、不同馆藏和服务的整合以及设施管理的组织框架。PI和团队参与的协作为该项目贡献了几项技术和专业知识。Dienst架构在包括网络计算机科学技术参考图书馆(NCSTRL)在内的一些分布式数字图书馆应用中被证明是有效的，它构成了该项目的技术基础，并提供了一个多层次参与的框架，包括开放档案倡议协议(基于Dienst协议)所规定的参与。项目工作人员在诸如都柏林核心和沃里克框架等元数据倡议和研究中发挥的持续领导作用，正在促进NSDL元数据标准的制定和纳入。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的专业知识。最后，项目团队对数字图书馆研究社区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.
