  1. CHRONOPOLIS AND METAARCHIVE: PRESERVATION COOPERATION: Paper - iPres 2010 - Vienna

    Minor, David; Phillips, Mark; Schultz, Matt
    This paper will examine ongoing work between two major preservation systems, the Chronopolis Digital Preservation Program, [6] and the MetaArchive Cooperative. [13] In the past year, these two systems have begun work on bridging their technical underpinnings to create a more robust, reliable, longlived preservation community for their users. The main emphasis of this work is moving data between a LOCKSS-based system (MetaArchive) and an iRODSbased one (Chronopolis). This work also involves several other emerging preservation micro-service tools and practices, and the expertise of the University of North Texas (UNT) Digital Library [21] in deploying them. The final result of this work is intended to be of three-fold benefit: 1) directly improving the services offered...

  2. PRESERVATION PLANNING: A COMPARISON BETWEEN TWO IMPLEMENTATIONS.: Paper - iPres 2010 - Vienna

    McKinney, Peter
    This paper examines preservation planning as it is implemented within the National Library’s preservation repository (Rosetta) and compares it directly to the PLATO tool created as part of the PLANETS project. Preservation planning is both a business precondition and the systematic framework defining any preservation action. At the National Library of New Zealand Te Puna Mātauranga o Aotearoa, preservation planning is embedded within the Rosetta system. For the Library, the challenge can be stated simply: preserve New Zealand’s digital documentary heritage. With no limitations or control over the format of the content that is collected and preserved, The National Library of New Zealand Te Puna Mātauranga o Aotearoa (NLNZ) has ‘issues’ to resolve before...

  3. PAPER TEMPLATE FOR IPRES 2010: QUALITY INSURANCE THROUGH BUSINESS PROCESS MANAGEMENT IN A FRENCH ARCHIVE: Paper - iPres 2010 - Vienna

    MASSOL, Marion; ROUCHON, Olivier
    This paper outlines the recent initiative run at CINES, a national IT datacentre for French academic researchers, to formalize the business processes of its department dedicated to the long-term preservation of digital objects, which is at present one of the very few operational long-term preservation platforms in France for the public sector and Higher Education and Research in particular. One of the strategic goals of this organization is the evaluation and assessment of service quality. The processes formalization activity – coupled with an external audit and an ITIL approach – highlighted the department good practices, gaps and weaknesses. The processes global map and most of the twenty detailed process maps have been put together...

  4. DIGITAL PRESERVATION FOR ENTERPRISE CONTENT: A GAP-ANALYSIS BETWEEN ECM AND OAIS: Paper - iPres 2010 - Vienna

    Korb, Joachim; Strodl, Stephan
    Today, more and more information is being produced in a digital form. In addition to this so-called born-digital content, material that was produced to exist in an analogue form is now being digitised both for preservation and for easier access. This digital information comes in an ever greater variety of formats, many of which are relatively short-lived. Newer versions of the same software are often unable to render files produced with older versions of that software, let alone files produced with similar software from other vendors. Soft- and hardware environments change constantly and after only a few years can older...

  5. BECOMING A CERTIFIED TRUSTWORTHY DIGITAL REPOSITORY: THE PORTICO EXPERIENCE: Paper - iPres 2010 - Vienna

    Kirchhoff, Amy; Morrissey, Sheila; Fenton, Eileen; Orphan, Stephanie
    The scholarly community’s dependence on electronic resources is rapidly increasing and those electronic resources are increasingly preserved in digital repositories or other preservation services. Whether locally hosted at libraries, collaboratively hosted between institutions, or externally hosted by a third party, one method for these digital repositories to take to assure themselves and their communities of their soundness is to be audited and certified by impartial organizations. Such independent organizations with staff experienced in executing audits and certifications can represent the interests of the academic community. Such staff will have the time and skills required to perform a thorough review of the methodologies and policies of each digital repository. Over the course of 2009, the Center...

  6. PRESERVATION OF DIGITISED BOOKS IN A LIBRARY CONTEXT: Paper - iPres 2010 - Vienna

    Zierau, Eld; Jensen, Claus
    The focus of this paper is on which digital objects to preserve when preserving digital library materials derived from original paper materials. It will investigate preservation strategies for digital objects from digitised paper material that must both be preserved and simultaneously retain a short route to dissemination. The investigation is based on a study of digitisation done a decade ago and digitisation done today. In the last decade mass digitisation has become more commonly used since technological evolution has made it cheaper and quicker. The paper explores whether there are parts of digital material digitised a decade ago worth preserving,...

  7. BUILDING BLOCKS FOR THE NEW KB E-DEPOT: Paper - iPres 2010 - Vienna

    van Wijngaarden, Hilde; Rog, Judith; Marijnen, Peter
    The National Library of the Netherlands (KB) will renew its digital archiving environment. The current system, the e-Depot with DIAS by IBM as its technical core, has been operational since 2003 and needs to be updated. More importantly, a new system is required because KB has published a new strategic plan with ambitious goals. They require development of an infrastructure that can process, store, preserve and retrieve millions of digital objects, now and for the long term. The digital collections will include e-journals, e-books, websites and digitized master images and will grow from 20 TB currently to 720 TB in...

  8. SEVEN STEPS FOR RELIABLE EMULATION STRATEGIES SOLVED PROBLEMS AND OPEN ISSUES: Paper - iPres 2010 - Vienna

    von Suchodoletz, Dirk; van der Hoeven, Jeffrey; Rechert, Klaus; Schr¨oder, Jasper
    After four years of research within the PLANETS project and two years of KEEP the jigsaw puzzle of emulation becomes a more complete picture. Emulation strategies are now seen as a viable complement to migration. A conceptual and theoretical groundwork has already been laid out, e.g. proper definition and selection of suitable emulators. However, integration into preservation frameworks and additional software archiving remain open research questions. This paper discusses several aspects of reliable integration and proposes development steps for a more complete emulation-based strategies in long-term preservation.

  9. ARCHIVEMATICA: USING MICRO-SERVICES AND OPEN-SOURCE SOFTWARE TO DELIVER A COMPREHENSIVE DIGITAL CURATION SOLUTION: Paper - iPres 2010 - Vienna

    Van Garderen, Peter
    Digital curation micro-services offer a light-weight alternative to preservation systems that are developed on digital repository and framework technology stacks. These are often too complex for small and medium-sized memory institutions to deploy and maintain. The Archivematica project has implemented a micro-services approach to develop an integrated suite of free and open-source tools that allows users to process digital objects from ingest to access while applying format specific preservation policies. Inspired by a call to action in a recent UNESCO Memory of the World report, the goal of the Archivematica project is to reduce the cost and technical complexity of deploying a comprehensive, interoperable digital curation solution that is compliant with standards and best...

  10. CONNECTING PRESERVATION PLANNING AND PLATO WITH DIGITAL REPOSITORY INTERFACES: Paper - iPres 2010 - Vienna

    Hitchcock, Steve; Rauber, Andreas; Kulovits, Hannes; Tarrant, David; Carr, Les
    An accepted digital preservation workflow is emerging in which file formats are identified and those believed to be at risk are migrated to what are perceived to be less risky formats. This raises important questions about what to convert and when, if at all. In other words, how to connect file identification and migration. This area has become known as preservation planning, and seeks to take account of a wide variety of factors that might impact preservation decisions. Broadly there are two approaches to preservation planning. One provided in some digital preservation systems is to simplify and reduce both the number of file formats stored and therefore limit the number of preservation...

  11. THE IMPORTANCE OF TRUST IN DISTRIBUTED DIGITAL PRESERVATION: A CASE STUDY FROM THE METAARCHIVE COOPERATIVE: Paper - iPres 2010 - Vienna

    Schultz, Matt; Gore, Emily B.
    Distributed digital preservation is a maturing and appealing solution to the pressing problem of ensuring the survivability of digital content. Like all other digital preservation efforts, distributed digital preservation solutions must communicate trust to their Designated Communities as they continue to mature. The following paper discusses the importance of establishing this trust, retraces the development of TRAC as a reliable tool for evaluating trustworthy repositories, and details the process of the MetaArchive Cooperative’s application of TRAC to its distributed digital preservation solution. This process revealed that the current metrics for gauging trust in digital preservation could be readily applied to distributed solutions with great effect. However, because these metrics often presume a more centralized approach...

  12. UROBE: A PROTOTYPE FOR WIKI PRESERVATION: Paper - iPres 2010 - Vienna

    Popitsch, Niko; Mosser, Robert; Philipp, Wolfgang
    More and more information that is considered for digital long-term preservation is generated by Web 2.0 applications like wikis, blogs or social networking tools. However, there is little support for the preservation of these data today. Currently they are preserved like regular Web sites without taking the flexible, lightweight and mostly graphbased data models of the underlying Web 2.0 applications into consideration. By this, valuable information about the relations within these data and about links to other data is lost. Furthermore, information about the internal structure of the data, e.g., expressed by wiki markup languages is not preserved entirely. We argue that this currently neglected information is of high value in a long-term...

  13. Policy-Driven Repository Interoperability: Enabling Integration Patterns for iRODS and Fedora: Paper - iPres 2010 - Vienna

    Pcolar, David; Marciano, Richard; Hou, Chien-Yi; Chassanoff, Alexandra; Davis, Daniel W.; Zhu, Bing
    Given the growing need for cross-repository integration to enable a trusted, scalable, open and distributed content infrastructure, this paper introduces the Policy- Driven Repository Interoperability (PoDRI) project investigating interoperability mechanisms between repositories at the policy level. Simply moving digital content from one repository to another may not capture the essential management policies needed to ensure its integrity and authenticity. Platform-independent, policyaware object models, including policy expressions, and a distributed architecture for policy-driven management are fundamental building blocks of a sustainable access and preservation infrastructure. This project integrates iRODS and Fedora to demonstrate such an infrastructure. Using iRODS and its rules engine, combined with Fedora’s rich semantic object model for digital objects, provides the basis for implementing...

  14. PRESERVING VISUAL APPEARANCE OF EGOVERNMENT WEB FORMS USING METADATA DRIVEN IMITATION: Paper - iPres 2010 - Vienna

    Nilsson, Jörgen
    This paper summarizes work done in a PhD study on metadata driven imitation for preservation of visual appearance of web forms and/or receipts used in eGovernment services. The research done suggests that metadata, and e.g. a background image, can be used to describe the visual appearance of documents, and that this also facilitates having the data separated from the visual appearance. This separation provides the ability to present the material to the users in different ways, depending on their needs and requirements, while retaining the ability to present the object in its original look. The original look is seen as the most versatile way of presenting the material, giving the most fruitful...

  15. ARCHIVING ARCHAEOLOGY: INTRODUCING THE GUIDES TO GOOD PRACTICE: Paper - iPres 2010 - Vienna

    Mitcham, Jenny; Niven, Kieron; Richards, Julian
    This paper looks at some of the domain specific preservation challenges faced by the Archaeology Data Service and how we work with these in order to maximise the re-use potential of the data that we archive. It looks in particular at one of the mandatory responsibilities of an Open Archival Information System (OAIS) and how we try to ensure that the data that we present to our designated community is ‘independently understandable’. The paper introduces the collaborative ‘Guides to Good Practice’ project which aims to provide data producers with the guidance that they need in order to create data that...

  16. EVALUATION OF BIT PRESERVATION STRATEGIES: Paper - iPres 2010 - Vienna

    Zierau, Eld; Bøgvad Kejser, Ulla; Kulovits, Hannes
    This article describes a methodology which supports evaluation of bit preservation strategies for different digital materials. This includes evaluation of alternative bit preservation solutions. The methodology presented uses the preservation planning tool Plato for evaluations, and a BR-ReMS prototype to calculate measures for how well bit preservation requirements are met. Planning storage of different types of data as part of preservation planning involves classification of the data with regard to requirements on confidentiality, bit safety, availability and costs. Selection of storage parameters is quite complex since e.g. more copies of data means better bit safety, but higher cost and higher...

  17. REPRESENTATION OF DIGITAL MATERIAL PRESERVED IN A LIBRARY CONTEXT: Paper - iPres 2010 - Vienna

    Zierau, Eld
    This article explores preservation of digital material in a library context with a focus on logical object modelling that takes both preservation and dissemination into account. The article describes normalisation of data expressed via a logical object model. This logical object model is designed to support the requirements for joint preservation and dissemination. Additionally the article includes a suggestion for a possible implementation that respects the logical object model. Formulation, of the requirements and possible implementation for a logical object model, is based on observation of current trends, as well as results from a research project on preservation strategies for libraries. The research project has been carried out at the Royal Library of Denmark,...

  18. APPROACHES TO ARCHIVING PROFESSIONAL BLOGS HOSTED IN THE CLOUD: Paper - iPres 2010 - Vienna

    Kelly, Brian; Guy, Marieke
    Early adopters of blogs will have made use of externally-hosted blog platforms, such as Wordpress.com and Blogger.com, due, perhaps, to the lack of a blogging infrastructure within the institution or concerns regarding restrictive terms and conditions covering use of such services. There will be cases in which such blogs are now well-established and contain useful information not only for current readership but also as a resource which may be valuable for future generations. The need to preserve content which is held on such third-party services (“the Cloud’) provides a set of new challenges which are likely to be distinct from the management of content hosted within the institution, for which institutional policies should address...

  19. Transfer and Inventory Services in Support of Preservation at the Library of Congress: Paper - iPres 2010 - Vienna

    Johnston, Leslie
    The digital content lifecycle is generally understood as a set of activities: select, get and/or produce, prepare and/or assemble, describe, manage, and, as appropriate, make available. At the bit level, digital content is viewed as files on a file system. Many crucial activities of the digital content lifecycle are therefore undertaken primarily at the bit level, including transferring, moving, and inventorying files, and verifying that files have not changed over time. The identifiable entities at the bit-level – files and directories -- are widely and easily understood by Library of Congress digital collection data managers and curators. As part of...

  20. LIFE3: A PREDICTIVE COSTING TOOL FOR DIGITAL COLLECTIONS: Paper - iPres 2010 - Vienna

    Hole, Brian; Wheatley, Paul; Lin, Li; McCann, Patrick
    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...
