aDORe：一个模块化的、基于标准的数字对象存储库
aDORe: a modular, standards-based Digital Object Repository
摘要：
本文介绍了aDORe存储库的架构，设计和实施的ingcapacity，存储和访问大量的数字对象在洛斯阿拉莫斯国家实验室的研究图书馆。aDORe架构是高度模块化和基于标准的。该体系结构采用MPEG-21数字项目声明语言作为基于XML的格式，将由多个数据流组成的数字对象表示为开放式档案信息系统档案信息包（OAIS AIP），通过摄取过程，将这些OAIS AIP存储在多个自治的档案库中。存储库索引跟踪所有自治存储库的创建和位置，而标识符索引则记录给定数字对象或OAIS AIP驻留在哪个自治存储库中。完整环境的前端，OAI-PMH联邦，用于请求OAIS传播信息包（OAIS DIP）。这些OAIS DIP可以是存储的OAIS AIP本身或其转换。该前端允许OAI-PMH收集器从aDORe循环地和有选择地收集OAIS DIP的批次，并因此使用收集的对象创建多个并行服务。另一个前端，OpenURL解析器，被引入用于请求OAIS结果集。OAIS结果集是单个数字对象或其组成数据流的传播。这两个前端都利用MPEG-21数字项目处理引擎将服务应用于OAIS AIP、数字对象或在传播请求中指定的组成数据流。
英文摘要：
This paper describes the aDORe repository architecture, designed and implemented for ingesting, storing, and accessing a vast collection of Digital Objects at the Research Library of the Los Alamos National Laboratory. The aDORe architecture is highly modular and standards-based. In the architecture, the MPEG-21 Digital Item Declaration Language is used as the XML-based format to represent Digital Objects that can consist of multiple datastreams as Open Archival Information System Archival Information Packages (OAIS AIPs).Through an ingestion process, these OAIS AIPs are stored in a multitude of autonomous repositories. A Repository Index keeps track of the creation and location of all the autonomous repositories, whereas an Identifier Locator registers in which autonomous repository a given Digital Object or OAIS AIP resides. A front-end to the complete environment, the OAI-PMH Federator, is introduced for requesting OAIS Dissemination Information Packages (OAIS DIPs). These OAIS DIPs can be the stored OAIS AIPs themselves, or transformations thereof. This front-end allows OAI-PMH harvesters to recurrently and selectively collect batches of OAIS DIPs from aDORe, and hence to create multiple, parallel services using the collected objects. Another front-end, the OpenURL Resolver, is introduced for requesting OAIS Result Sets. An OAIS Result Set is a dissemination of an individual Digital Object or of its constituent datastreams. Both front-ends make use of an MPEG-21 Digital Item Processing Engine to apply services to OAIS AIPs, Digital Objects, or constituent datastreams that were specified in a dissemination request.
