“…-Most emulators do not offer a possibility to copy contents from the emulated environment to the host environment. Phelps and Watry [2005] see this as a major drawback for using emulators for digital preservation. Usually it is necessary to be able to access documents and reuse the contents of those documents in the host environment.…”

Accessible emulation is often the method of choice for maintaining digital objects, specifically complex ones such as applications, business processes, or electronic art. However, validating the emulator's ability to faithfully reproduce the original behavior of digital objects is complicated.This article presents an evaluation framework and a set of tests that allow assessment of the degree to which system emulation preserves original characteristics and thus significant properties of digital artifacts. The original system, hardware, and software properties are described. Identical environment is then recreated via emulation. Automated user input is used to eliminate potential confounders. The properties of a rendered form of the object are then extracted automatically or manually either in a target state, a series of states, or as a continuous stream. The concepts described in this article enable preservation planners to evaluate how emulation affects the behavior of digital objects compared to their behavior in the original environment. We also review how these principles can and should be applied to the evaluation of migration and other preservation strategies as a general principle of evaluating the invocation and faithful rendering of digital objects and systems. The article concludes with design requirements for emulators developed for digital preservation tasks. ACM Reference Format:Guttenbrunner, M. and Rauber, A. 2012.

“…83 Late migration is also the principle underlying the Multivalent browser, which uses an extensible set of media adaptors to provide contemporaneous support for behaviors primarily applicable to document-centric content whose formats are invariant over time. 84 Since 2004 Cornell University has operated a File Format and Media Migration Pilot Service (FFMM) to help maintain the continuing viability of faculty-produced data stored in obsolete, or obsolescing, formats and media. 85 The provisional service was developed locally in reaction to the perception that commercial data conversion and recovery services were prohibitively expensive.…”

Catalogue Entry DescriptionThe goal of digital curation is to ensure the appropriate usability of managed digital assets over time. Format is a fundamental characteristic of a digital asset that governs its ability to be used effectively. Without strong format typing a digital asset is merely an undifferentiated string of bits. The information content encoded into an asset's bits can only be interpreted properly and rendered in human-sensible form if that asset's format is known. While it is possible for bits to be preserved indefinitely without consideration of format, it is only through the careful management of format that the meaning of those bits remains accessible over time. This instalment investigates aspects of format description, validation, and characterisation that may assist with long-term curation and usability of data. Publisher Citation GuidelinesStephen Abrams, (October 2007), "File Formats", DCC Digital Curation Manual, S.Ross, M.Day (eds), Retrieved , from http://www.dcc.ac.uk/resource/curation-manual/chapters/file-formats About the DCCThe JISC-funded Digital Curation Centre (DCC) provides a focus on research into digital curation expertise and best practice for the storage, management and preservation of digital information to enable its use and re-use over time. The project represents a collaboration between the University of Edinburgh, the University of Glasgow through HATII, UKOLN at the University of Bath, and the Council of the Central Laboratory of the Research Councils (CCLRC). The DCC relies heavily on active participation and feedback from all stakeholder communities. For more information, please visit www.dcc.ac.uk. The DCC is not itself a data repository, nor does it attempt to impose policies and practices of one branch of scholarship upon another. Rather, based on insight from a vibrant research programme that addresses wider issues of data curation and long-term preservation, it will develop and offer programmes of outreach and practical services to assist those who face digital curation challenges. It also seeks to complement and contribute towards the efforts of related organisations, rather than duplicate services. DCC -Digital Curation Manual Editors PrefaceThe Digital Curation Centr...
