Identifying Barriers to File Rendering in Bit-level Preservation Repositories: A Preliminary Approach

This paper seeks to advance digital preservation theory and practice by presenting an evidence-based model for identifying barriers to digital content rendering within a bit-level preservation repository. It details the results of an experiment at the University of Illinois at Urbana-Champaign library, where the authors procured a random sample of files from their institution’s digital preservation repository and tested their ability to open said files using software specified in local policies. This sampling regime furnished a preliminary portrait of local file rendering challenges, and thus preservation risk, grounded not in nominal preferences for one format’s characteristics over another, but in empirical evidence of what types of files present genuine barriers to staff and patron access. This research produced meaningful diagnostic data to inform file format policymaking for the repository.

Service-oriented models for audiovisual content storage

What are the important topics to understand if involved with storage services to hold digital audiovisual content? This report takes a look at how content is created and moves into and out of storage; the storage service value networks and architectures found now and expected in the future; what sort of data transfer is expected to and from an audiovisual archive; what transfer protocols to use; and a summary of security and interface issues

PREMIS Requirement Statement Project Report

This is the report of the PRESTA Project, the objective of which was to develop a requirements specification for preservation metadata based on the PREMIS (PREservation Metadata: Implementation Strategies) final report, the Data Dictionary for Preservation Metadata

BlogForever: D3.1 Preservation Strategy Report

This report describes preservation planning approaches and strategies recommended by the BlogForever project as a core component of a weblog repository design. More specifically, we start by discussing why we would want to preserve weblogs in the first place and what it is exactly that we are trying to preserve. We further present a review of past and present work and highlight why current practices in web archiving do not address the needs of weblog preservation adequately. We make three distinctive contributions in this volume: a) we propose transferable practical workflows for applying a combination of established metadata and repository standards in developing a weblog repository, b) we provide an automated approach to identifying significant properties of weblog content that uses the notion of communities and how this affects previous strategies, c) we propose a sustainability plan that draws upon community knowledge through innovative repository design

The Long and Short of IT: The International Development Research Centre as a Case Study for a Long-term Digital Preservation Strategy

This thesis is a contribution to the study of the challenges facing archivists and record managers working on the long-term management and preservation of digital records. This thesis discusses the International Development Research Centre (IDRC), a Canadian government Crown agency, as a case study. In 2004 IDRC's Resarch Information Management Service (RIMS) Division was given the responsibility for developing a digital preservation program for the centre's final reports and related documentation. To facilitate this work, it hired a student intern to research recommendations for a digital preservation strategy. My research as the centre's intern led to the following recommendations for IDRC: Choose file formats that are ubiquitous, non-proprietary (when possible), viable, and lossless; Implement a strategy of conversion and migration of file formats and media as they become obsolete; Capture metadata to support the preservation of and access to digital objects; and Comply with the Open Archival Information System (OAIS) reference model. Much academic study by archivists on digital preservation focuses on the concepts relating to digital records and records management. This thesis offers a practical institutional example of one effort to develop an actual archival program.Master of Arts in Archival Studie
