Digitised and born-digital Audio-Visual (AV) content
presents new challenges for preservation and Quality Assurance
(QA) to ensure that cultural heritage is accessible for the long
term. Digital archives have developed strategies for avoiding,
mitigating and recovering from digital AV loss using IT-based
systems, involving QA tools before ingesting files into the archive
and utilising file-based replication to repair files that may be
damaged while in the archive. However, while existing strategies
are effective for addressing issues related to media degradation,
issues such as format obsolescence and failures in processes and
people pose significant risk to the long-term value of digital
AV content. We present a Business Process Risk management
framework (BPRisk) designed to support preservation experts
in managing risks to long-term digital media preservation. This
framework combines workflow and risk specification within a
single risk management process designed to support continual
improvement of workflows. A semantic model has been developed
that allows the framework to incorporate expert knowledge from
both preservation and security experts in order to intelligently
aid workflow designers in creating and optimising workflows.
The framework also provides workflow simulation functionality,
allowing users to a) understand the key vulnerabilities in the
workflows, b) target investments to address those vulnerabilities,
and c) minimise the economic consequences of risks. The application of the BPRisk framework is demonstrated on a use case
with the Austrian Broadcasting Corporation (ORF), discussing
simulation results and an evaluation against the outcomes of
executing the planned workflow
