Tools for modelling and simulating migration-based preservation
This report describes two tools for modelling and simulating the costs and risks of using IT storage systems for the long-term archiving of file-based AV assets. The tools include a model of storage costs, the ingest and access of files, the possibility of data corruption and loss from a range of mechanisms, and the impact of having limited resources with which to fulfill access requests and preservation actions. Applications include archive planning, development of a technology strategy, cost estimation for business planning, operational decision support, staff training and generally promoting awareness of the issues and challenges archives face in digital preservation

BlogForever: D3.1 Preservation Strategy Report
This report describes preservation planning approaches and strategies recommended by the BlogForever project as a core component of a weblog repository design. More specifically, we start by discussing why we would want to preserve weblogs in the first place and what it is exactly that we are trying to preserve. We further present a review of past and present work and highlight why current practices in web archiving do not address the needs of weblog preservation adequately. We make three distinctive contributions in this volume: a) we propose transferable practical workflows for applying a combination of established metadata and repository standards in developing a weblog repository, b) we provide an automated approach to identifying significant properties of weblog content that uses the notion of communities and how this affects previous strategies, c) we propose a sustainability plan that draws upon community knowledge through innovative repository design
Sharing Social Research Data in Ireland: A Practical Tool
Your data is valuable and has an importance outside your own original project. Allowing other researchers to reuse your data maximises the impact of your work, and benefits both the scholarly community and society in general. Sharing your data allows other researchers to use your material in ways you may not have thought of, or may not have been able to do within your research project. It allows other researchers to replicate your findings, to verify your results, test your instruments and compare with other studies. It also allows them to use your work to expand knowledge in important areas. It provides value for money by reducing duplication and advancing knowledge and also has a significant value in education, as it allows both graduate and under-graduate students to develop their skills in qualitative and quantitative research by using high-quality data in their studies, without having to conduct their own surveys.Archiving your data also guarantees its long-term preservation and accessibility. As many research teams are assembled only for individual projects, long-term preservation and access to research data collections can only be guaranteed if they are deposited in an archive which will manage them, ensure access and provide user-support. In addition, the archives will ensure that the datasets do not become obsolescent or corrupted.Finally, increasingly funders require that you make your research data available as a condition of their funding your research, so that other researchers can test your findings, and use your data to extend research in your area. Equally, publishers are also specifying access to research data as a condition for publication
PRONOM-ROAR: Adding Format Profiles to a Repository Registry to Inform Preservation Services
To date many institutional repository (IR) software suppliers have pushed the IR as a digital preservation solution. We argue that the digital preservation of objects in IRs may better be achieved through the use of light-weight, add-on services. We present such a service – PRONOM-ROAR – that generates file format profiles for IRs. This demonstrates the potential of using third- party services to provide preservation expertise to IR managers by making use of existing machine interfaces to IRs
Planets: Integrated Services for Digital Preservation
The Planets Project is developing services and technology to address core challenges in digital preservation. This article introduces the motivation for this work, describes the extensible technical architecture and places the Planets approach into the context of the Open Archival Information System (OAIS) Reference Model. It also provides a scenario demonstrating Planets’ usefulness in solving real-life digital preservation problems and an overview of the project’s progress to date
The LIFE2 final project report
Executive summary: The first phase of LIFE (Lifecycle Information For E-Literature) made a major contribution to
understanding the long-term costs of digital preservation; an essential step in helping
institutions plan for the future. The LIFE work models the digital lifecycle and calculates the
costs of preserving digital information for future years. Organisations can apply this process
in order to understand costs and plan effectively for the preservation of their digital
collections
The second phase of the LIFE Project, LIFE2, has refined the LIFE Model adding three new
exemplar Case Studies to further build upon LIFE1. LIFE2 is an 18-month JISC-funded
project between UCL (University College London) and The British Library (BL), supported
by the LIBER Access and Preservation Divisions. LIFE2 began in March 2007, and
completed in August 2008.
The LIFE approach has been validated by a full independent economic review and has
successfully produced an updated lifecycle costing model (LIFE Model v2) and digital
preservation costing model (GPM v1.1). The LIFE Model has been tested with three further
Case Studies including institutional repositories (SHERPA-LEAP), digital preservation
services (SHERPA DP) and a comparison of analogue and digital collections (British Library
Newspapers). These Case Studies were useful for scenario building and have fed back into
both the LIFE Model and the LIFE Methodology.
The experiences of implementing the Case Studies indicated that enhancements made to the
LIFE Methodology, Model and associated tools have simplified the costing process. Mapping
a specific lifecycle to the LIFE Model isn’t always a straightforward process. The revised and
more detailed Model has reduced ambiguity. The costing templates, which were refined
throughout the process of developing the Case Studies, ensure clear articulation of both
working and cost figures, and facilitate comparative analysis between different lifecycles.
The LIFE work has been successfully disseminated throughout the digital preservation and
HE communities. Early adopters of the work include the Royal Danish Library, State
Archives and the State and University Library, Denmark as well as the LIFE2 Project partners.
Furthermore, interest in the LIFE work has not been limited to these sectors, with interest in
LIFE expressed by local government, records offices, and private industry. LIFE has also
provided input into the LC-JISC Blue Ribbon Task Force on the Economic Sustainability of
Digital Preservation.
Moving forward our ability to cost the digital preservation lifecycle will require further
investment in costing tools and models. Developments in estimative models will be needed to
support planning activities, both at a collection management level and at a later preservation
planning level once a collection has been acquired. In order to support these developments a
greater volume of raw cost data will be required to inform and test new cost models. This
volume of data cannot be supported via the Case Study approach, and the LIFE team would
suggest that a software tool would provide the volume of costing data necessary to provide a
truly accurate predictive model
