NSDL的信息网络覆盖结构
An Information Network Overlay Architecture for the NSDL
摘要：
我们描述了核心集成团队（CI）的国家科学数字图书馆（NSDL）的一个新的体系结构的底层数据模型和实现。该体系结构是基于信息网络覆盖的概念。这个网络在Fedora存储库中以数字对象图的形式实现，允许表示多个信息实体及其关系。该体系结构提供了一个框架，上下文和资源的重用，我们认为是必不可少的实用程序的NSDL作为教学和学习的工具。
英文摘要：
We describe the underlying data model and implementation of a new architecture for the National Science Digital Library (NSDL) by the Core Integration Team (CI). The architecture is based on the notion of an information network overlay. This network, implemented as a graph of digital objects in a Fedora repository, allows the representation of multiple information entities and their relationships. The architecture provides the framework for contextualization and reuse of resources, which we argue is essential for the utility of the NSDL as a tool for teaching and learning.
