Digital Preservation Lifecycle Management: Building A Demonstration Prototype for the Preservation of Large Scale Multimedia Collections

因此，数字图书馆和数字档案界发现自己面临着独特的保存挑战，这些挑战要求全面的数字保存生命周期管理过程。反过来，这些过程需要不引人注目，对内容生产和传播的影响最小。为了让内容创作者尽可能容易地长期保存他们的内容，保存过程应该整合到内容生产生命周期中。这个项目将展示一种软件技术，它将包括这样一个视频收藏的保存环境，其中包括其他相关的多媒体内容，如音频、文字记录、注释、相关和介绍性网页，以及目前正在FileMakerProTM数据库中捕获的描述性、技术性和权利性元数据。该提议是采用目前在小规模演播室环境中用于制作和网络广播视频内容的现有视频制作工作流程，并将其与数字保存生命周期管理过程相结合，以使数字内容能够存档以供长期保存。《与历史对话》由加州大学伯克利分校制作，由加州大学圣地亚哥分校电视台(UCSD-TV)编辑，并通过UCTV进行广播和网络广播。主要的研发挑战是解决保存过程的开发和自动化，这些过程理解视频集合和相关内容的加入、描述、组织和保存。这些过程的自动化需要将现役生产中使用的工作流系统与保存系统相结合，并跟踪保存过程的执行情况，以完成和恢复错误。该系统将通过以下方式展示一种有效的保存方法：1)确保对具有关键持久重要性的有风险的多媒体收藏提供“最后手段”的保存；2)确保对将随着时间扩大和演变的收藏提供保存，同时管理基础软件技术的演变；以及3)展示了数字保存生命周期管理的标准参考模型，该模型可以集成到活动的生产工作流程中。INTELLECTUAL优点：由NSF和国会图书馆主办的2002年4月研讨会的一份报告指出，迫切需要解决方案来防止有价值的数字信息进一步丢失--这些问题非常紧迫--现在需要采取行动，而不是在未来的某个时候。拟议的数字保存生命周期管理演示通过表明当前的软件系统提供了所需的功能，可以大规模实施，并且可以保存处于风险中的收藏品，从而解决了这一关键问题。演示将展示一种多媒体材料的摄取模型和收藏管理，其中保存的智力资本很容易获得，研究成果、教育材料和新知识可以长期顺利地纳入。该系统集成了数字图书馆、数据网格和永久存档技术，目标是为长期收藏管理和保存提供基本的构建块。BROADER影响：NSF网络基础设施计划、国会图书馆国家数字信息基础设施和保存计划(NDIIPP)和国家档案和记录管理局(NARA)电子文件档案馆都积极关注数据的保存。展示从生产环境中提取材料并将材料导入可扩展保存环境的能力对于使保存可行至关重要。出版、保存、联合和分析的演示将向包括人文学家、社会科学家、科学家、工程师、学生和普通公众在内的广泛社区证明保护概念。将示范项目扩展到生产设施将使其他公共和有风险的数字内容得以保存。保护架构将支持现有数字图书馆和保护环境的联合，使该设施能够扩展到所有社区。它将提供一个可复制的模型，展示一个系统，该系统可以为真正的国家保护骨干提供可伸缩的原型。

Increasingly, intellectual content is 'born digital', as a consequence of which the digital library and digital archival communities find themselves faced with unique preservation challenges, challenges that call for comprehensive digital preservation lifecycle management processes. These processes, in turn, need to be unobtrusive, with minimal impact on content production and dissemination. In order to make it as easy as possible for content creators to preserve their content for the long-term, preservation processes should be integrated into the content production lifecycle. This project will demonstratef a software technology that will comprise such a preservation environment for a video collection that includes other related multi-media content such as audio, transcripts, annotations, related and introductory Web pages, and descriptive, technical, and rights metadata currently being captured in a FileMakerProTM database. The proposal is to take an existing video production workflow that is currently being used for producing and Web-casting video content in a small-scale studio setting, and to integrate it with a digital preservation life-cycle management process that will enable the digital content to be archived for long-term preservation. The collection, 'Conversations with History', is produced at the University of California, Berkeley, edited by University of California, San Diego TV (UCSD-TV), and broadcast and Web-cast through UCTV.The major research and development challenge to address the development and automation of preservation processes that comprehend the accession, description, organization, and preservation of the video collection and associated content. The automation of these processes requires the integration of workflow systems that are used in active production with preservation systems, and the tracking of the execution of the preservation processes for completion and error recovery. The system will demonstrate an effective preservation methodology by 1) ensuring that preservation 'of last resort' is available for at-risk multi-media collections of critical lasting importance; 2) ensuring that preservation is available for collections that will expand and evolve over time, while managing evolution in the underlying software technologies; and 3) demonstrating a standard reference model for digital preservation lifecycle management that can be integrated into active production workflows.INTELLECTUAL MERIT: A report from the April 2002 workshop sponsored by the NSF and the Library of Congress states 'Solutions are urgently needed to prevent further loss of valuable digital information - these problems are urgent - action is needed now, not some time in the future'. The proposed demonstration of digital preservation lifecycle management addresses this critical problem by showing that current software systems provide the required functionality, can be implemented at scale, and can preserve at-risk collections. The demonstration will show an ingestion model and collection management for multi-media material, in which preserved intellectual capital is easily accessible, and research results, educational material, and new knowledge can be incorporated smoothly over the long term. The system integrates digital library, data grid, and persistent archive technologies, with the goal of providing a fundamental building block for long-term collection management and preservation.BROADER IMPACT: The NSF Cyberinfrastructure program, the Library of Congress National Digital Information Infrastructure and Preservation Program (NDIIPP), and the National Archives and Records Administration (NARA) Electronic Records Archive all are actively concerned with the preservation of data. The demonstration of the ability to extract material from a production environment and import thematerial into a scalable preservation environment is essential for making preservation viable. The demonstration of publication, preservation, federation, and analysis will serve as a proof of preservationconcepts to a broad community including humanists, social scientists, scientists, engineers, students, andthe general public. The extension of the demonstration project into a production facility will enable otherpublic and at-risk digital content to be preserved. The preservation architecture will support federation ofexisting digital libraries and preservation environments, enabling the expansion of the facility to allcommunities. It will provide a replicable model that will demonstrate a system that can contribute to ascalable prototype for a truly national preservation backbone.
