Distributed Digital Preservation

Creating a framework to build effective, reliable, and auditable digital preservation environments with large geographic spreads.

Distributed Digital Preservation (DDP) uses highly distributed methodologies, infrastructures, and organizational apparatuses in order to achieve the reliable persistence of digital content. Worldwide, numerous digital preservation initiatives are already engaging these practices. Existing DDP approaches, as well as those that have yet to come into being, lack common vocabulary and conceptual frameworks for building effective, reliable, and auditable preservation environments. Agreed-upon terminology and theoretical models would:

  • Help initiatives to describe and compare their infrastructures and operations.
  • Increase understanding and awareness of the DDP process both by practitioners and by organizations seeking preservation solutions.
  • Provide auditors (including self-auditors) with a crucial foundation for assessing the reliability of a variety of distributed approaches.

The preservation field today relies upon the Reference Model for an Open Archival Information System (OAIS) to provide theoretical and abstract models and vocabulary for digital preservation. Educopia's DDP research expands on the OAIS framework to define the methodology and structure of the actions undertaken in organizationally and/or technically distributed preservation repositories. The Framework does not intend to redefine existing standards. Instead it merely seeks to elaborate with additional models and vocabulary.
