Digital Object Formats


All documents to be shared must conform to widely known structural schema. Information protocol and representation standards are also criti-cal. Many such standards are used to facilitate interchange between oth-erwise autonomous individuals and agencies.232 However, having too many standards can present more difficulties than having too few. For in-stance, the National Alliance for Health Information Technology identifies more than 450 mandatory and voluntary standards, more than 200 organi-zations with standards working groups, and more than 900 standards publications!

    Levy 1998, Heroic Measures: Reflections on the Possibility and Purpose of Digital Preservation, comments: “Within the archival community, whose focus... has been on paper, microform, and [so on], the predominant answer to [“preserving what?”] has shifted over time.... [I]n the early nineteenth century, archivists took their mission to be the preservation of the information contained in documents rather than the original documents themselves.... It was only... in the twentieth century, that advances in preservation theory and practice... made... possible... preserving... original materials. The pendulum thus swung from... preserving the information content of documents to... preserving the artifacts themselves.” Beedham 2005, Assessment of UKDA and TNA Compliance with OAIS and METS Standards, p. 89, presents a U.K. viewpoint.Google Scholar

    Gracy 2004, The Preservation of Moving Images, also comments, “If the lack of standards for video preservation makes conservation-minded information professionals uneasy, the state of digital preservation is likely to incite a full-fledged panic attack. No longer are we merely coping with the chemical instability of the recording media; the obsolescence of the recording formats takes precedent [sic] as the new preservation challenge. And in the last twenty years, we have seen a staggering array of digital formats—with more being developed on what seems like a weekly basis.”Google Scholar

    Williams 2002, Preserving TV and Broadcast Archives, communicates that the BBC holds about 1.7 million items of film and videotape, about 800,000 radio recordings, four million items of sheet music, three million photographs, and 22.5 million newspaper clippings. See also Wright 2004, Digital preservation of audio, video and film. Wright communicated that the BBC collection occupies about 100 kilometers of shelves. Its video media formats include 2,” 1,” 3/4″ = UMatic, BetaSP, DigiBeta, D3, DVCPRO, DVCAM tapes. Its audio media formats include 78, 33, 45 rpm discs, 1/4″ tape, CD, and minidisks in various encoding formats, Moving films occur on 35 and 16 mm tape, some black-and-white and some color, with several kinds of sound tracks (optical, magnetic; on the same carrier as the images or separate) on several kinds of film stock.Google Scholar
