    This research paper presents a cost engine system that estimates the whole life cycle cost of long-term digital preservation (LTDP) activities using cloud-based technologies. A qualitative research methodology has been employed and the activity based costing (ABC) technique has been used to develop the cost model. The unified modelling language (UML) notation and the object oriented paradigm (OOP) are utilised to design the architecture of the software system. In addition, the service oriented architecture (SOA) style has been used to deploy the function of the cost engine as a web service in order to ensure its accessibility over the web. The cost engine is a module that is part of a larger digital preservation system and has been validated qualitatively through experts’ opinion. Its benefits are realised in the accurate and detailed estimation of cost for companies wishing to employ LTDP activities

    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 future preservation costs is vital to answering a range of important questions for each. The LIFE (Life Cycle Information for E-Literature) project, which has just completed its third phase, helps institutions and researchers address these concerns, reducing the financial and preservation risks, and allowing decision makers to assess a range of options in order to achieve effective preservation while operating within financial restraints. The project is a collaboration between University College London (UCL), The British Library and the Humanities Advanced Technology and Information Institute (HATII) at the University of Glasgow. Funding has been supplied in the UK by the Joint Information Systems Committee (JISC) and the Research Information Network (RIN)

    Understanding and communicating the cost and value of digital curation activities has now been recognised by a number of projects and initiatives as a very important factor in ensuring the longterm survival of digital assets. A number of projects have developed costing models for digital preservation but there remains a major problem with information assets (digital or otherwise) in that their value is difficult to express in terms that are readily understood by all the stakeholders, especially those who might fund their preservation. This paper introduces a range of issues concerning information value and business models for sustained funding of digital preservation, with particular reference to the espida Project recently completed at the University of Glasgow. This project has developed a model of information value that builds on the Balanced Scorecard approach to business performance developed by Kaplan and Norton. This model casts information curation as an investment where current and ongoing expenditure is incurred in order to produce future returns, benefiting a range of stakeholders. In this formulation, value is seen as multifaceted and, from the point of view of the individual or organisation funding the curation, explicitly related to the funder’s strategic goals. It also recognises that benefits may only accrue over the long term and that there is a risk that information that is preserved may fail to deliver any return. Examples discussed in the paper concern the establishment of an institutional repository and the establishment of an e-thesis service for an educational institution. It concludes that a deconstruction of benefits of this kind can be more quickly and fully understood even by stakeholders not necessarily expert in the curation field. This facilitates the production of a well-constructed case that clearly articulates information value and the benefit that accrues from its curation, which in turn allows senior management or other funders to make funding decisions based on understandable information: the basic premise of good practice in management. This is a commonly understood idea and one that the espida methodology helps fulfil

    Planning strategically, designing architecturally : a framework for digital library services

    Get PDF
    In an era of unprecedented technological innovation and evolving user expectations and information seeking behaviour, we are arguably now an online society, with digital services increasingly common and increasingly preferred. As a trusted information provider, libraries are in an advantageous position to respond, but this requires integrated strategic and enterprise architecture planning, for information technology (IT) has evolved from a support role to a strategic role, providing the core management systems, communication networks, and delivery channels of the modern library. Further, IT components do not function in isolation from one another, but are interdependent elements of distributed and multidimensional systems encompassing people, processes, and technologies, which must consider social, economic, legal, organisational, and ergonomic requirements and relationships, as well as being logically sound from a technical perspective. Strategic planning provides direction, while enterprise architecture strategically aligns and holistically integrates business and information system architectures. While challenging, such integrated planning should be regarded as an opportunity for the library to evolve as an enterprise in the digital age, or at minimum, to simply keep pace with societal change and alternative service providers. Without strategy, a library risks being directed by outside forces with independent motivations and inadequate understanding of its broader societal role. Without enterprise architecture, it risks technological disparity, redundancy, and obsolescence. Adopting an interdisciplinary approach, this conceptual paper provides an integrated framework for strategic and architectural planning of digital library services. The concept of the library as an enterprise is also introduced

    Preservation for Institutional Repositories: practical and invisible

    No full text
    With good prospects for growth in institutional repository (IR) contents, in the UK, due to the proposed RCUK policy on mandating deposit of papers on funded work, and internationally due to the Berlin 3 recommendation, it is timely to investigate preservation solutions for IRs. The paper takes a broad view of preservation issues for IRs - based on practice, experience and visions for the future - from the perspective of Preserv, a JISC-funded project. It considers preservation in the context of IRs. Based on the OAIS preservation model, an architecture is proposed to support distributed preservation services for IRs. Work performed so far involves adapting the IR user deposit interface in a pilot version of EPrints software for building IRs, and determining accurate file format information using Pronom software. The paper looks ahead briefly at the role of preservation service providers, working for the IR, within this architecture. The strategy is to take practical steps that are, as far as possible, invisible to all but those concerned with the preservation process for IRs

    Technical alignment

    Get PDF
    This essay discusses the importance of the areas of infrastructure and testing to help digital preservation services demonstrate reliability, transparency, and accountability. It encourages practitioners to build a strong culture in which transparency and collaborations between technical frameworks are valued highly. It also argues for devising and applying agreed-upon metrics that will enable the systematic analysis of preservation infrastructure. The essay begins by defining technical infrastructure and testing in the digital preservation context, provides case studies that exemplify both progress and challenges for technical alignment in both areas, and concludes with suggestions for achieving greater degrees of technical alignment going forward

    D3.2 Cost Concept Model and Gateway Specification

    Get PDF
    This document introduces a Framework supporting the implementation of a cost concept model against which current and future cost models for curating digital assets can be benchmarked. The value built into this cost concept model leverages the comprehensive engagement by the 4C project with various user communities and builds upon our understanding of the requirements, drivers, obstacles and objectives that various stakeholder groups have relating to digital curation. Ultimately, this concept model should provide a critical input to the development and refinement of cost models as well as helping to ensure that the curation and preservation solutions and services that will inevitably arise from the commercial sector as ‘supply’ respond to a much better understood ‘demand’ for cost-effective and relevant tools. To meet acknowledged gaps in current provision, a nested model of curation which addresses both costs and benefits is provided. The goal of this task was not to create a single, functionally implementable cost modelling application; but rather to design a model based on common concepts and to develop a generic gateway specification that can be used by future model developers, service and solution providers, and by researchers in follow-up research and development projects.<p></p> The Framework includes:<p></p> • A Cost Concept Model—which defines the core concepts that should be included in curation costs models;<p></p> • An Implementation Guide—for the cost concept model that provides guidance and proposes questions that should be considered when developing new cost models and refining existing cost models;<p></p> • A Gateway Specification Template—which provides standard metadata for each of the core cost concepts and is intended for use by future model developers, model users, and service and solution providers to promote interoperability;<p></p> • A Nested Model for Digital Curation—that visualises the core concepts, demonstrates how they interact and places them into context visually by linking them to A Cost and Benefit Model for Curation.<p></p> This Framework provides guidance for data collection and associated calculations in an operational context but will also provide a critical foundation for more strategic thinking around curation such as the Economic Sustainability Reference Model (ESRM).<p></p> Where appropriate, definitions of terms are provided, recommendations are made, and examples from existing models are used to illustrate the principles of the framework

    Planning and managing the cost of compromise for AV retention and access

    No full text
    Long-term retention and access to audiovisual (AV) assets as part of a preservation strategy inevitably involve some form of compromise in order to achieve acceptable levels of cost, throughput, quality, and many other parameters. Examples include quality control and throughput in media transfer chains; data safety and accessibility in digital storage systems; and service levels for ingest and access for archive functions delivered as services. We present new software tools and frameworks developed in the PrestoPRIME project that allow these compromises to be quantitatively assessed, planned, and managed for file-based AV assets. Our focus is how to give an archive an assurance that when they design and operate a preservation strategy as a set of services, it will function as expected and will cope with the inevitable and often unpredictable variations that happen in operation. This includes being able to do cost projections, sensitivity analysis, simulation of “disaster scenarios,” and to govern preservation services using service-level agreements and policies
