摘要：

我们描述了（NSDL）国家科学，数学，工程和技术教育数字图书馆的体系结构的核心组成部分。随着时间的推移，NSDL将包括异构用户、内容和服务。为了适应这一点，一个技术和组织基础设施的设计已经制定了一个频谱的互操作性的概念为基础。本文描述了互操作性基础设施的第一阶段，包括元数据存储库、搜索和发现服务、权限管理服务和用户界面门户设施。

英文摘要：

We describe the core components of the architecture for the (NSDL) National Science, Mathematics, Engineering, and Technology Education Digital Library. Over time the NSDL will include heterogeneous users, content, and services. To accommodate this, a design for a technical and organization infrastructure has been formulated based on the notion of a spectrum of interoperability. This paper describes the first phase of the interoperability infrastructure including the metadata repository, search and discovery services, rights management services, and user interface portal facilities.
