This report on preservation strategies covers three different but related areas. It begins with business models and value-chains and concerns how a preservation strategy can be funded. This section includes four case studies: the Institut National l’Audiovisuel (INA), the BBC, ORF and Beeld en Geluid. It then goes into the more technical area of preservation management and compares different strategies (using long-lived media, migration, Multivalent) as well as discussing modelling the costs of preservation and access, specifically storage. It concludes with an overview of existing preservation metadata models with the focus on technical metadata. This last section includes a detailed description of the technical structure of data in audio WAV files, covers the essentials of digital video as well as the structure of QuickTime (MOV), MXF and MPEG-2 files. It then moves on to discuss how this technical information may be structured within various preservation metadata schemas.
This report covers a lot of ground in 100 pages. Its clearly stated conclusions and recommendations at the end of each section are particularly useful for management level decision making. The specific file format migration workflow models can be interesting to smaller archives even though they are based on real use cases in large, broadcast archives. The section describing the technical structure of audio and video files provides a good introduction for av archivists not completely familiar with av collections in the digital domain.
