Core Integration Services for a Federated NSDL

该试点项目正在为SMET教育国家数字图书馆建立一个技术基础设施，方便用户发现和访问各种数字材料的集合，并为数字图书馆奠定坚实的社会基础，为其成员提供表达其愿景的声音，公平的治理结构和社区领导的机会。项目活动借鉴了地球科学界迄今在构想地球系统教育数字图书馆（DLESE）并为其奠定组织和管理基础方面的经验。还正在开发一套工具和服务，以支持成员集合并帮助它们实现互操作性。该项目这方面的主要合作伙伴包括圣地亚哥超级计算机中心和加州大学-圣巴巴拉的亚历山大数字图书馆项目。示例包括用于交叉集合搜索的协议;用于持久存储、身份验证和相关需求的中央服务;以及帮助材料分类和发现、最终用户支持和使用监控的工具。认识到这一努力对更大的科学，数学，工程和技术教育企业的重要性，NSF地球科学理事会为该项目提供了大量的共同资金。

This pilot project is building both a technical infrastructure that facilitates user discovery of and access to collections of diverse digital material for a national digital library for SMET Education, and a strong social foundation for the digital library that provides for its members a voice for their vision, an equitable governance structure, and opportunities for community leadership. Project activities build on the geoscience community's experiences to date in conceptualizing and laying the organizational and managerial foundation for a Digital Library for Earth System Education (DLESE). A suite of tools and services is also being developed to support member collections and help them achieve interoperability. Key partners in this aspect of the project include the San Diego Supercomputer Center and the Alexandria Digital Library project at the University of California - Santa Barbara. Examples include protocols for cross-collection searching; central services for persistent storage, authentication, and related needs; and tools that aid in materials classification and discovery, end-user support, and usage monitoring. Recognizing the importance of this effort to the larger science, mathematics, engineering, and technology education enterprise, the NSF Geosciences Directorate is providing significant co-funding for this project.
