Preserving Video Objects and Context: A Demonstration Project

知识价值数字保存是世纪初的重大挑战之一。世界各地的国家图书馆和档案馆都在努力保护数字资产。世界各地的供资机构认识到保护的必要性，并正在为各种研究和开发项目提供资金。随着数字图书馆和数字化计划在过去十年中的发展，越来越多的研究人员，信息专业人员和政策制定者已经解决了创建，维护和保存数字对象的问题。尽管迄今为止大多数保存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的一种更常见的表达媒介，并提出了独特的保存挑战。该项目建立在早期关于数字视频文件及其替代品的工作（http：//www.example.com）的基础上，寻求保留视频作品背景并突出其本质的方法，从而使后代更容易理解和使用。www.open-video.org长期提供情境化访问，使数字对象随着时间的推移而变得可理解，这对长期保存至关重要。该项目将重点开发一个数字视频背景的保存框架，该框架可供档案管理员用于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其应用于两个重要的数字视频收藏来演示该框架：从1983年到2000年，美国宇航局播放了一系列完整的教育录像，并在年度会议上提交了一整套由ACM SIGCHI评审的录像。现在的将提供使用测试集的框架和可演示的示例，以便在未来几年内为视频档案决策提供信息。更广泛的影响这项工作将对各种利益攸关方产生若干重要成果。首先，它将在理论和实践两个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创造，并提出如何进一步利用技术，使其更有效率和效力。其次，这项工作将定义数字视频，一个越来越重要的媒体，迄今为止很少受到关注的保存参数。第三，这项工作将有很高的回报，集中注意力在两个重要的和实质性的视频内容集合。这些集合已经被数百万学生和教师（NASA）以模拟或广播形式使用，并被数千名人机交互学生和教师以模拟或数字本地形式使用。特别是美国宇航局的视频是为了鼓励妇女和少数民族参与科学和更广泛和更有效的可用性将加强这一使命。第四，该项目将汇集不同的实践社区，从多个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作用不仅将产生一个更强大的保存框架，而且还将使这些不同群体更好地理解数字保存问题。最后，该项目将产生重大影响，因为它是根据新的创新筹资模式的要求调整的。

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.
