Intellectual MeritDigital preservation stands as one of the grand challenges of the early 21st Century. National libraries and archives from around the world are grappling with the preservation of digital assets. Funding agencies worldwide recognize the preservation imperative and are funding a wide array of research and development projects. As digital libraries and digitization initiatives have grown over the past decade, an increasing number of researchers, information professionals, and policy makers have addressed the issues around creating, maintaining, and, most recently, preserving digital objects. Although most of the preservation research to date has centered on text and still images, video is becoming a more common medium of expression for science and education and offers unique preservation challenges. This project builds on earlier work with digital video files and their surrogates (http://www.open-video.org), seeking ways in which to preserve a video work's context and highlighting its essence, thus making it more understandable and accessible to future generations. Long-term provision of contextualized access that makes digital objects understandable over time is essential to longterm preservation. This project will focus on developing a preservation framework for digital video context that can be used by archivists to make preservation decisions and guide the development of finding aids.The work will include a demonstration of this framework by applying it to two important digital video collections: the complete series of NASA broadcast educational videos and the complete set of juried ACM SIGCHI videos presented at annual conferences from 1983 to the present. The framework and demonstrable examples using the test collections will be made available to inform video archival decisions in the immediate years ahead. Broader ImpactsThis work will have several important outcomes for a variety of stakeholders. First, it will address the important context aspect of digital preservation on both theoretical and practical fronts. This should improve archival decision making and finding aid creation and suggest ways to leverage technology further to make them more efficient and effective. Second, this work will define preservation parameters for digital video, an increasingly important medium that has to date received little attention. Third, this work will have high payoff by focusing attention on two important and substantial collections of video content. These collections are already used in analog or broadcast forms by millions of students and teachers (NASA) and in analog or digital local forms by thousands of human-computer interaction students and faculty. The NASA videos in particular were created to encourage women and minority participation in science and broader and more effective availability will enhance this mission.. Fourth, this project will bring together diverse communities of practice ranging from academics in multiple disciplines to publishers to educational technologists. The synergies such crossdisciplinary collaborations offer will not only result in a more robust framework for preservation but will also produce better understanding of digital preservation issues across these different communities. Finally, this project will have substantial impact because it is tuned to the requirements of a new and innovative funding model.

知识价值数字保存是 21 世纪初面临的重大挑战之一。世界各地的国家图书馆和档案馆都在努力保护数字资产。世界各地的资助机构认识到保护的必要性，并正在资助各种研究和开发项目。随着过去十年数字图书馆和数字化计划的发展，越来越多的研究人员、信息专业人员和政策制定者开始解决有关创建、维护以及最近保存数字对象的问题。尽管迄今为止大多数保护研究都集中在文本和静态图像上，但视频正在成为科学和教育更常见的表达媒介，并带来了独特的保护挑战。该项目建立在早期数字视频文件及其替代品 (http://www.open-video.org) 的基础上，寻求保留视频作品背景并突出其本质的方法，从而使其更易于理解和使用后代。长期提供情境化访问，使数字对象随着时间的推移变得易于理解，这对于长期保存至关重要。该项目将重点开发数字视频环境的保存框架，档案管理员可以使用该框架来做出保存决策并指导查找辅助工具的开发。该工作将包括通过将该框架应用于两个重要的数字视频收藏来演示该框架：从 1983 年至今，NASA 播放的完整系列教育视频以及在年度会议上展示的全套 ACM SIGCHI 评审视频。使用测试集合的框架和可演示的示例将在未来几年内为视频存档决策提供信息。更广泛的影响这项工作将为各种利益相关者带来一些重要成果。首先，它将在理论和实践方面解决数字保存的重要背景问题。这将改善档案决策和寻找援助的创造，并提出进一步利用技术的方法，使它们更加高效和有效。其次，这项工作将定义数字视频的保存参数，数字视频是一种日益重要的媒体，迄今为止却很少受到关注。第三，通过将注意力集中在两个重要且实质性的视频内容集合上，这项工作将获得很高的回报。这些馆藏已以模拟或广播形式被数百万学生和教师 (NASA) 使用，并以模拟或数字本地形式被数千名人机交互学生和教师使用。 NASA 的视频尤其是为了鼓励妇女和少数族裔参与科学而制作的，更广泛、更有效的可用性将增强这一使命。第四，该项目将汇集不同的实践社区，从多学科的学者到出版商再到教育技术专家。这种跨学科合作所提供的协同效应不仅会产生更强大的保存框架，而且还将更好地理解这些不同社区的数字保存问题。最后，该项目将产生重大影响，因为它适应了新的创新融资模式的要求。
