aDORe联合体系结构
The aDORe Federation Architecture
摘要：
联合存储库的需求出现在两个不同的场景中。在一个场景中，存储库操作中与可伸缩性相关的问题达到了一个点，超过这个点，持续的服务需要并行化，因此需要存储库基础设施的联合。在另一个场景中，多个分布式存储库管理某些社区或应用程序感兴趣的集合，联合是一种跨这些存储库呈现统一视角的方法。在这两种情况下，高级的3层aDORe联邦体系结构都可以用作联邦存储库的指导方针。本文描述了该体系结构，包括第1层中的联合存储库的核心接口，第2层中的两个共享基础设施组件，以及第3层中对联合的单点访问。本文还说明了aDORe联邦架构的两个大规模部署：洛斯阿拉莫斯国家实验室的aDORe档案库（超过1亿个数字对象）和根特大学图像库联邦（多TB的图像文件）。
英文摘要：
The need to federate repositories emerges in two distinctive scenarios. In one scenario, scalability-related problems in the operation of a repository reach a point beyond which continued service requires parallelization and hence federation of the repository infrastructure. In the other scenario, multiple distributed repositories manage collections of interest to certain communities or applications, and federation is an approach to present a unified perspective across these repositories. The high-level, 3-Tier aDORe federation architecture can be used as a guideline to federate repositories in both cases. This paper describes the architecture, consisting of core interfaces for federated repositories in Tier-1, two shared infrastructure components in Tier-2, and a single-point of access to the federation in Tier-3. The paper also illustrates two large-scale deployments of the aDORe federation architecture: the aDORe Archive repository (over 100,000,000 digital objects) at the Los Alamos National Laboratory and the Ghent University Image Repository federation (multiple terabytes of image files).
