Abstract: Long-term retention and access to audiovisual (AV) assets as part of a preservation strategy inevitably involve some form of compromise in order to achieve acceptable levels of cost, throughput, quality, and many other parameters. Examples include quality control and throughput in media transfer chains; data safety and accessibility in digital storage systems; and service levels for ingest and access for archive functions delivered as services. We present new software tools and frameworks developed in the PrestoPRIME project that allow these compromises to be quantitatively assessed, planned, and managed for file-based AV assets. Our focus is how to give an archive an assurance that when they design and operate a preservation strategy as a set of services, it will function as expected and will cope with the inevitable and often unpredictable variations that happen in operation. This includes being able to do cost projections, sensitivity analysis, simulation of “disaster scenarios,” and to govern preservation services using service-level agreements and policies.

bio
M. J. Addis leads a portfolio of applied research projects at the IT Innovation Centre on media archiving and digital preservation, risk management, and smart systems. Current work includes cost models, uncertainty management, and service-oriented approaches to distributed media systems. Addis has ten years of experience in working with broadcasters, post houses and film archives to develop strategies, tools, and systems for audiovisual restoration, preservation, and archiving. Through AVATAR-m in the UK and PrestoPRIME in Europe, Addis has investigated long-term data retention and access for AV when using ICT systems and has developed related strategies for risk management, migration, and archiving as a service. Recently, this has resulted in the IT Innovation Centre, forming the Arkivum Ltd., which provides data archiving as a service, with Addis as chief technology officer.
M. Jacyno
bio
Mariusz Jacyno received a PhD. from the University of Southampton in 2011 where he investigated the problem of engineering autonomic IT systems. Before joining the IT Innovation Centre as a research engineer, he worked on a number of projects in which he was involved in modeling of distributed and complex IT systems using agent-based techniques. His current work involves using the agent- and event-based simulation models to model large-scale archive systems, media format migration workflows and internet communities in order to identify risks and costs inherent in these systems. His main interests are in the area of complex systems modeling and distributed AI.
M. Hall-May
bio
Martin Hall-May holds a PhD. in computer science. He is currently a senior research engineer at the University of Southampton IT Innovation Centre, where he is involved in research and integration activities in the EC FP7 PrestoPRIME and SERSCIS projects. These and other projects in which he has been involved focus on the modeling of risk, especially as applied to the dependability of service oriented architectures. However, the application of these techniques is not limited to the preservation of AV content. Hall-May's research aims to show the application of similar techniques to the management of information flows in critical infrastructures, such as air traffic management, as well as in the long-term preservation of engineering data. Before joining IT Innovation, he researched large-scale system safety and the implications of deploying autonomous vehicles in safety-critical applications.
M. McArdle
bio
Mark McArdle is a research engineer at the IT Innovation Centre. McArdle has interests in the multimedia sector as well as archive and digital preservation. His current development projects include MServe, a scalable multimedia digital content platform, that has applications in preservation and media post-production. McArdle currently leads the development and maintains the direction of MServe across multiple U.K. and European projects. Other interests include 3D digital rendering and scalable web services.
S. C. Phillips
bio
Stephen C. Phillips is a project manager and senior research engineer at IT Innovation. Through national and European projects Phillips has spent more than seven years working in the area of service oriented architectures with a special focus on management systems and service-level agreements. His current work with major broadcasters and archives in the PrestoPRIME project is complimented by his experience of designing service management systems for companies in the aerospace, automotive and pharmaceutical industries. Phillips has a background in chemistry and mathematics and a PhD. in computational chemistry.
