Developing a robust migration workflow for preserving and curating hand-held media
Many memory institutions hold large collections of hand-held media, which can comprise hundreds of terabytes of data spread over many thousands of data-carriers. Many of these carriers are at risk of significant physical degradation over time, depending on their composition. Unfortunately, handling them manually is enormously time consuming and so...Dappert, Angela ; Jackson, Andrew ; Kimura, Akiko

An analysis of contemporary JPEG2000 codecs for image format migration
This paper presents results of an analysis of different implementations of the JPEG2000 standard, specifically part 1: JP2, an image format that is currently popular within the digital preservation community. In particular we are interested in the effect different JPEG2000 codecs (encoders and decoders) have on image quality in response...Palmer, William ; May, Peter ; Cliff, Peter

Quality assured image file format migration in large digital object repositories
This article gives an overview on how different components developed by the SCAPE project are intended to be used in composite file format migration workflows; it will explain how the SCAPE platform can be employed to make sure that the workflows can be used to migrate very large image collections...Schlarb, Sven ; Cliff, Peter ; May, Peter ; Palmer, William ; Hahn, Matthias …

CRISP: Crowdsourcing Representation Information to Support Preservation
In this paper, we describe a new collaborative approach to the collection of representation information to ensure long term access to digital content. Representation information is essential for successful rendering of digital content in the future. Manual collection and maintenance of RI has so far proven to be highly resource...Pennock, Maureen ; Jackson, Andrew N. ; Wheatley, Paul

People mashing: Agile digital preservation and the AQuA Project
Manual quality assurance (QA) of digitised content is typically fallible and can result in collections that are marred by a variety of quality and access issues. Poor storage conditions, technology obsolescence and other unforeseen problems can also leave digital objects in an unusable state. Detecting, identifying and ultimately fixing these...Wheatley, Paul ; Middleton, Bo ; Double, Jodie ; Jackson, Andrew ; McGuinness, Rebecca

Using Automated Dependency Analysis to generate representation information
To preserve access to digital content, we must preserve the representation information that captures the intended interpretation of the data. In particular, we must be able to capture performance dependency requirements, i.e. to identify the other resources that are required in order for the intended interpretation to be constructed successfully....Jackson, Andrew

Deal with conflict, capture the relationship: the case of digital object properties
Properties of digital objects play a central role in digital preservation. All key preservation services are linked via a common understanding of the properties which describe the digital objects in a repository's care. Unfortunately, different services deal with properties on sometimes different levels of description. While, for example, a preservation...Dappert, Angela

A METS based information package for long term accessibility of web archives
The British Library’s web archive comprises several terabyte of harvested websites. Like other content streams this data should be ingested into the library’s central preservation repository. The repository requires a standardized Submission- and Archival Information Package. Harvested Websites are stored in Archival Information Packages (AIP). Each AIP is described by...Enders, Markus

LIFE3: A predictive costing tool for digital collections
Predicting the costs of long-term digital preservation is a crucial yet complex task for even the largest repositories and institutions. For smaller projects and individual researchers faced with preservation requirements, the problem is even more overwhelming, as they lack the accumulated experience of the former. Yet being able to estimate...Hole, Brian ; Lin, Li ; McCann, Patrick ; Wheatley, Paul

Capturing and replaying streaming media in a web archive – a British Library case study
A prerequisite for digital preservation is to be able to capture and retain the content which is considered worth preserving. This has been a significant challenge or web archiving, especially for websites with embedded streaming media content, which cannot be copied via a simple HTTP request to a URL. This...Hockx-Yu, Helen ; Crawford, Lewis ; Coram, Roger ; Johnson, Stephen
