DAVID D2.2: Analysis of loss modes in preservation systems

This is a report on the way in which loss and damage to digital AV content occurs for different content types, AV data carriers and preservation systems.Three different loss modes have been identified, and each has been analysed in terms of existing solutions and longterm effects. This report also includes an in-depth treatment of format compatibility (interoperability issues), format resilience to carrier degradation and format resilience to corruption

DAVID: D3.5 - Recommendations and techniques for content in a "born robust" form

This deliverable describes the demand, the concept and suggests solutions for born robust audio-visual files. A list of tools fostering file robustness is presented as well as the current state of born robust attributes in the standardisation process media formats

DAVID D3.3 - Final IT-based tools and strategies for avoiding, mitigating and recovering from digital AV loss & final conceptual risk management framework and tools for digital AV preservation

This is the final report from the DAVID project on IT-based tools, strategies and risk management for digital Audio-visual (AV) preservation.Digitised and born-digital AV content presents new challenges for preservation and long-term quality assurance. Archives have rapidly developed strategies for avoiding, mitigating and recovering from digital AV loss using IT-based systems. The problems affecting digital AV content and the strategies against AV loss adopted by INA and ORF are discussed in this report.A risk-based framework based on the essential properties of AV assets and documented preservation metadata is required to determine how best to minimise the risk of digital damage. This report presents a conceptual risk management framework responding to the requirements of archive risk management, and presents a set of tools developed by the DAVID partners. This report also contains a specific use case of a real-life MXF repair process at ORF, showing how risk modelling and simulation can be used in practice
