  1. VidArch Preserving Video Objects and Context: A Demonstration Project Helen R. Tibbo School of Information and Library Science University of North Carolina at Chapel Hill tibbo@ils.unc.edu

  2. Funding for this Project This work was supported by a grant from the National Science Foundation #IIS 0455970 DigArch Program IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  3. Sanghee Oh Yaxiao Song VidArch Team • Gary Marchionini • Helen Tibbo • Christopher Lee • Paul Jones Special Thanks to SILS Students: • Dawne Howard • Terrell Russell IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  4. VidArch Partners • National Aeronautics and Space Administration (NASA) • Association of Computing Machinery (ACM) • Open Video (OV) • ibiblio IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  5. Challenges of Video Preservation • Temporal medium with multiple information representation channels; • Multiple visual and audio • Human-readable or machine-readable content • Video object’s meaning is greater than the sum of its parts; • Preservation must attend to the whole as well as the parts. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  6. Preservation & Access • Are integrally intertwined; • Accessibility and use promote longevity (Conway); • “Mechanisms to ensure long-term persistence should operate harmoniously with mechanisms supporting dissemination and use. (Lavoie & Dempsey) IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  7. Goals of Project • Make videos not only accessible, but also understandable in the future; • Develop a preservation framework for digital video context that includes preservation of persistent context; • Develop a workflow model that focuses on the capture of contextual information; • Explore the design and feasibility of a video or multimedia-enhanced finding aid; • Develop decision support tools for the acquisition, ingest, and preservation of context. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  8. Theoretical Foundation • Builds from OAIS Reference Model; • Blends conceptualizing power of archival finding aids with complexity and information-rich nature of video; • Based in the vision that long-term provision of contextualized access • Makes digital objects understandable over time; • Is essential to long-term preservation; • Is dependent on metadata. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  9. Metadata • Several schemes and standards – METS, NLNZ, etc.; • Preservation metadata – PREMIS; • What is needed for long-term access and understandability? • Object-specific annotations; • Collection-level descriptions and integration/ links among objects; • State of the world information. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  10. Context… • Can make materials useful and comprehendible across time and space; • Is a hallmark of a well-written finding aid; • Is often expensive to capture. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  11. Open Video • Housed within SILS; • Collects and makes available digitized video content for a wide audience; • Significantly, Open Video began as a project to provide researchers with access to video to facilitate the study of video problems; • It now finds itself a repository with preservation as well as access needs. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  13. NASA Collection • 2003, partnered with NASA Langley’s Center for Distance Learning; • OV provides digital video file version of four educational programs; • Video comes from NASA and passes through the OV workflow. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  14. NASA Collection on OV IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  15. NASA’s Own Video Site IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  16. ACM Collection • Videos presented at research conference sponsored by the Association of Computing Machinery; • SIGCHI has accepted juried videos since 1983; • 427 videos in OV’s ACM collection; • Videos of widely varying quality with a range of metadata. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  17. VidArch Methodology • Explore Open Video workflow; • Identify sources of context from OV workflow process; • Build framework to articulate sources of context in OAIS model and OV workflow; • Create media-enhanced finding aids that capture context. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  18. Finding Aids • Traditional tools of archivists but have not often been exploited in digital library settings; • FAs provide context for access and understandability over time; • FAs can contain several levels of hierarchy: • the entire collection; • series and subseries; and • listing of individual materials. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  19. EAD Finding Aids • Encoded Archival Description FAs designed to be highly accessible and interoperable; • EAD FAs can take advantage of multiple media, hyperlinks, and interactive behaviors. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  20. Finding Aids & Context • Traditionally, context in finding aids relates to the entities involved in the creation of the records • individuals, • organizations and functions, and • the nature of the records themselves. • FAs involve substantial intellectual work and professional judgment on the part of archivists. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  21. VidArch View of Finding Aids • FAs should be considered not just access devices but also digital objects; • FAs should be ingested into the OAIS and preserved along with the target videos; • Identifying a typology of elements (related actors, events, objects, locations, times), to be documented within video collections; • Finding aids can be enriched with links to media objects. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  22. NASA Collection Finding Aid IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  23. Digital Archiving & OAIS Model • OAIS indicates the importance of contextual information but does not describe how to specify it. • We seek to develop a further articulation of how context can best be preserved within the OAIS framework. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  24. Life Cycle of Digital Videos from NASA in Open Video IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  25. Workflow and Sources of Context • The solid arrows in the figure show current information flows; • Dashed arrows indicate potential for capturing further contextual information; • 1st Stage: Functional provenance within NASA; • 2nd Stage: Video production activities NASA; • 3rd Stage: Distribution of the video. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  26. OAIS, SIPS, & AIPS • An OAIS differs from other types of information systems in that it accepts “responsibility to preserve information and make it available for a Designated Community” over the “long-term.” • This responsibility is only assured for information that has been submitted to the OAIS as an SIP and then ingested in order to become an AIP. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006

  27. Curator’s OAIS Responsibilities • Curators of digital video collections must decide what subset of the total potential documentation (existing or created by the curator) related to the digital videos should be • reflected in the descriptive and access tools of the archive and • submitted to the archive as SIPs in order to be ingested for long-term preservation. IS&T Archiving Conference 2006 Ottawa, Canada, May 26, 2006
