Preservation Health Check: Monitoring Threats to Digital Repository Content Metadata

Metadata describes a digital item, providing (if known) such information as creator, publisher, contents, size, relationship to other resources, and more. Metadata may also contain "preservation" components that help us to maintain the integrity of digital files over time.

  • Content Description: The Open Planets Foundation (OPF) has suggested the need for digital preservation repositories to perform periodic “health checks” as a routine part of their preservation activities. In the same way that doctors monitor basic health properties of their patients to spot indications of infirmity, repositories should monitor a set of properties associated with “preservation health” to provide an early warning of potential threats to the ongoing security of the archived digital objects in their care. The Preservation Health Check (PHC) project, undertaken as a joint effort by OPF and OCLC Research, aims to evaluate the usefulness of the preservation metadata created and maintained by operational repositories for assessing basic preservation properties. The PHC project seeks to develop an implementable logic to support preservation health checks of this kind, and to test this logic against the store of preservation metadata maintained by an operational preservation repository. The Bibliothèque Nationale de France has agreed to share their preservation metadata in support of this project. The authors aim is to advance the use of preservation metadata as an evidence base for conducting preservation health checks according to a standardized, widely-applicable protocol. Doing so opens up possibilities for internal or third-party threat assessment services that can be used for internal repository planning and auditing/certification. Accordingly, this paper provides background on the problem addressed by the PHC project, the authors' approach for operationalizing the concept of a preservation health check, some preliminary findings, and next steps. The report is important for anyone involved with defining, implementing and promoting the use of preservation metadata and for those trying to get a handle on how preservation metadata works with threat models.
