JISC/NPO studies on the preservation of electronic materials: A framework of data types and formats, and issues affecting the long term preservation of digital material
CA Proposes a framework for preserving digital objects and discusses steps in the preservation process. Addresses a series of four questions: Why preserve? How much? How? And Where? Proposes a "Preservation Complexity Scorecard" to help identify the complexity of preservation needs and the appropriate preservation approach for a given object. "Although a great deal has been discussed and written about digital material preservation, there would appear to be no overall structure which brings together the findings of the numerous contributors to the debate, and allows them to be compared. This Report attempts to provide such a structure, whereby it should be possible to identify the essential elements of the preservation debate and to determine objectively the criticality of the other unresolved issues. This Report attempts to identify the most critical issues and employ them in order to determine their affect [sic] on preservation practice." (p. 5)
Conclusions
RQ "The study concludes that the overall management task in long term preservation is to moderate the pressure to preserve (Step 1) with the constraints dictated by a cost-effective archive (Step 3). This continuing process of moderation is documented through the Scorecard." (p. 6) "The Study overall recommends that a work programme should be started to: (a) Establish a Scorecard approach (to measure preservation complexity), (b) Establish an inventory of archive items (with complexity ratings) and (c) Establish a Technology Watch (to monitor shifts in technology), in order to be able to manage technological change. And in support of this, (a) establish a programme of work to explore the interaction of stakeholders and a four level contextual mode in the preservation process." (p. 6) A four level contextual approach, with data dictionary entry definitions, should be built in order to provide an information structure that will permit the successful retrieval and interpretation of an object in 50 years time. A study should be established to explore the principle of encapsulating documentsusing the four levels of context, stored in a format, possibly encrypted, that can be transferred across technologies and over time. <warrant> (p. 31) A more detailed study should be made of the inter-relationships of the ten stakeholders, and how they can be made to support the long term preservation of digital material. This will be linked to the economics of archive management (the cost model), changes in legislation (Legal Deposit, etc.), the risks of relying on links between National Libraries to maintain collections (threats of wholesale destruction of collections), and loss through viruses (technological turbulence). (p. 36) A technology management trail (within the Scorecard -- see Step 2 of the Framework) should be established before the more complex digital material is stored. This is to ensure that, for an item of digital material, the full extent of the internal interrelationships are understood, and the implications for long term preservation in a variety of successive environments are documented.

SOW
DC "The study is part of a wider programme of studies, funded by the Joint Information Systems Committee ("JISC"). The programme was initiated as a consequence of a two day workshop at Warwick University, in late November 1995. The workshop addressed the Long Term Preservation of Electronic Materials. The attendees represented an important cross-section of academic, librarian, curatorial, managerial and technological interests. 18 potential action points emerged, and these were seen as a basis for initiating further activity. After consultation, JISC agreed to fund a programme of studies." (p. 7) "The programme of studies is guided by the Digital Archive Working Group, which reports to the Management Committee of the National Preservation Office. The programme is administered by the British Library Research and Innovation Centre." (p. 2)
