Digital Preservation Services : State of the Art Analysis
Research report funded by the DC-NET project.An overview of the state of the art in service provision for digital preservation and curation. Its focus is on the areas where bridging the gaps is needed between e-Infrastructures and efficient and forward-looking digital preservation services. Based on a desktop study and a rapid analysis of some 190 currently available tools and services for digital preservation, the deliverable provides a high-level view on the range of instruments currently on offer to support various functions within a preservation system.European Commission, FP7peer-reviewe
Digital Preservation, Archival Science and Methodological Foundations for Digital Libraries
Digital libraries, whether commercial, public or personal, lie at the heart of the information society. Yet, research into their long‐term viability and the meaningful accessibility of their contents remains in its infancy. In general, as we have pointed out elsewhere, ‘after more
than twenty years of research in digital curation and preservation the actual theories, methods and technologies that can either foster or ensure digital longevity remain
startlingly limited.’ Research led by DigitalPreservationEurope (DPE) and the Digital
Preservation Cluster of DELOS has allowed us to refine the key research challenges – theoretical, methodological and technological – that need attention by researchers in digital libraries during the coming five to ten years, if we are to ensure that the materials held in our emerging digital libraries are to remain sustainable, authentic, accessible and understandable over time. Building on this work and taking the theoretical framework of archival science as bedrock, this paper investigates digital preservation and its foundational role if digital libraries are to have long‐term viability at the centre of the
global information society.

Critique of Architectures for Long-Term Digital Preservation
Evolving technology and fading human memory threaten the long-term intelligibility of many kinds of documents. Furthermore, some records are susceptible to improper alterations that make them untrustworthy. Trusted Digital Repositories (TDRs) and Trustworthy Digital Objects (TDOs) seem to be the only broadly applicable digital preservation methodologies proposed. We argue that the TDR approach has shortfalls as a method for long-term digital preservation of sensitive information. Comparison of TDR and TDO methodologies suggests differentiating near-term preservation measures from what is needed for the long term.
TDO methodology addresses these needs, providing for making digital documents durably intelligible. It uses EDP standards for a few file formats and XML structures for text documents. For other information formats, intelligibility is assured by using a virtual computer. To protect sensitive information—content whose inappropriate alteration might mislead its readers, the integrity and authenticity of each TDO is made testable by embedded public-key cryptographic message digests and signatures. Key authenticity is protected recursively in a social hierarchy. The proper focus for long-term preservation technology is signed packages that each combine a record collection with its metadata and that also bind context—Trustworthy Digital Objects.
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

Building information modeling – A game changer for interoperability and a chance for digital preservation of architectural data?
Digital data associated with the architectural design-andconstruction
process is an essential resource alongside -and even
past- the lifecycle of the construction object it describes. Despite
this, digital architectural data remains to be largely neglected in
digital preservation research – and vice versa, digital preservation
is so far neglected in the design-and-construction process. In the
last 5 years, Building Information Modeling (BIM) has seen a
growing adoption in the architecture and construction domains,
marking a large step towards much needed interoperability. The
open standard IFC (Industry Foundation Classes) is one way in
which data is exchanged in BIM processes. This paper presents a
first digital preservation based look at BIM processes,
highlighting the history and adoption of the methods as well as
the open file format standard IFC (Industry Foundation Classes)
as one way to store and preserve BIM data
Taste and the algorithm
Today, a consistent part of our everyday interaction with art and aesthetic artefacts occurs through digital media, and our preferences and choices are systematically tracked and analyzed by algorithms in ways that are far from transparent. Our consumption is constantly documented, and then, we are fed back through tailored information. We are therefore witnessing the emergence of a complex interrelation between our aesthetic choices, their digital elaboration, and also the production of content and the dynamics of creative processes. All are involved in a process of mutual influences, and are partially determined by the invisible guiding hand of algorithms.
With regard to this topic, this paper will introduce some key issues concerning the role of algorithms in aesthetic domains, such as taste detection and formation, cultural consumption and production, and showing how aesthetics can contribute to the ongoing debate about the impact of today’s “algorithmic culture”
