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. It is our contention that metadata is crucial for access and substantial context is crucial for understanding over time. We therefore 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 framework will include cost considerations from several angles including the degree to which elements may be automated. Beyond the obvious issues of saving and systematically migrating primary video objects in digital form, we observe three kinds of contextual digital video preservation challenges and propose addressing each of them in this project.
The first challenge is related to the question of what metadata and surrogates to preserve;
The second challenge is related to the question of what levels of granularity to preserve and especially how the metadata and accompanying contextual information should be associated and/or replicated;
The third challenge is related to what user interactions, system states, and pertinent world states should be preserved.
We will demonstrate and evaluate 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.
