  1. CAPTURING AND REPLAYING STREAMING MEDIA IN A WEB ARCHIVE – A BRITISH LIBRARY CASE STUDY: Paper - iPres 2010 - Vienna

    Hockx-Yu, Helen; Johnson, Stephen; Crawford, Lewis; Coram, Roger
    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 for web archiving, especially for websites with embedded streaming media content, which cannot be copied via a simple HTTP request to a URL. This paper describes the approach taken by the British Library in capturing and replaying streaming media in a web archive. A working system is now in place which will lead to the development of more generic tools and workflows, contributing to addressing a common challenge for the web archiving community. The British Library recently archived a large scale public arts project website, http://www.oneandother.co.uk,...

  2. PROPOSING A FRAMEWORK AND A VISUAL TOOL FOR ANALYSING GAPS IN DIGITAL PRESERVATION PRACTICE – A CASE STUDY AMONG SCIENTIFIC LIBRARIES IN EUROPE: Paper - iPres 2010 - Vienna

    Gomm, Moritz; Hemmje, Matthias; Brocks, Holger; Schrimpf, Sabine; Werkmann, Björn
    In this paper we present a case study and selected results from a research on digital preservation amongst digital libraries in Europe. We propose a framework for gap analysis in digital preservation encompassing the diffusion of preservation practices and the life-cycle of data. We also present a Gap Analysis Tool that we developed to support visual analysis of gaps in the implementation of digital preservation amongst communities. We discuss selected results from the application of the tool in the community of libraries in Europe.

  3. RESHAPING THE REPOSITORY: THE CHALLENGE OF EMAIL ARCHIVING: Paper - iPres 2010 - Vienna

    Goethals, Andrea; Gogel, Wendy
    Because of the historical value of email in the late 20th and 21st centuries, Harvard University Libraries began planning for an email archiving project in early 2007. A working group comprised of University archivists, curators, records managers, librarians and technologists studied the problem and recommended the undertaking of a pilot email archiving project at the University Library. This two-year pilot would implement a system for ingest, processing, preservation, and eventual end user delivery of email, in anticipation of it becoming an ongoing central service at the University after the pilot. This paper describes some of the unexpected challenges encountered during the pilot project and how they were addressed by design decisions. Key challenges...

  4. MOPSEUS – A DIGITAL REPOSITORY SYSTEM WITH SEMANTICALLY ENHANCED PRESERVATION SERVICES: Paper - iPres 2010 - Vienna

    Gavrilis, Dimitris; Angelis, Stavros; Papatheodorou, Christos
    Repository platforms offer significant tools aiding institutions to preserve the wealth of their information resources. This paper presents the data model as well as the architectural features of Mopseus, a digital library service, built on top of Fedora-commons middleware, designed to facilitate institutions to develop and preserve their own repositories. The main advantage of Mopseus is that it minimizes the customization and programming effort that Fedora-commons involves. Moreover it provides an added value service which semantically annotates the internal structure of a Digital Object. The paper focuses on the preservation functionalities of Mopseus and presents a mechanism for automated generation...

  5. A DATA-FIRST PRESERVATION STRATEGY: DATA MANAGEMENT IN SPAR: Paper - iPres 2010 - Vienna

    Fauduet, Louise; Peyrard, Sébastien
    The Bibliothèque nationale de France has developed its trusted digital repository, SPAR (Scalable Preservation and Archiving Repository), as a data-first system. This implies having fully described collections, through use of metadata standards in the information packages, such as METS, PREMIS, MIX or textMD, in a way that will make sense given the diversity of our documents. The need for full documentation also applies to the system itself. On the one hand, SPAR is self-describing in order to ensure its durability. On the other hand, all the information that is ingested into the system contributes to determine its settings and its behavior. The Data Management module is at the heart of these information flows. We...

  6. A METS BASED INFORMATION PACKAGE FOR LONG TERM ACCESSIBILITY OF WEB ARCHIVES: Paper - iPres 2010 - Vienna

    Enders, Markus
    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 a METS file. Operational metadata for resource discovery as well as archival metadata are normalized and embedded in the METS descriptor using common metadata profiles such as PREMIS and MODS. The British Library’s METS profile for web archiving considers dissemination and preservation use cases ensuring the authenticity of data. The underlying complex content model disaggregates websites into web pages, associated objects and their actual digital manifestations. The...

  7. RELEVANT METADATA TO PRESERVE “ALIEN” AIP: Paper - iPres 2010 - Vienna

    Di Iorio, Angela; Lunghi, Maurizio
    This article describes the development of Archives Ready To Archival Information Packages (AIP) Transmission a PREMIS Based Project (ARTAT). Following the project approach, the starting phase consisted of prototyping a layer conveying preservation metadata, which can be encoded from the existing archival systems, and exchanged with other repositories. This layer called Preservation Metadata Layer (PML) uses PREMIS semantics as the common language to overcome archival systems differences, and to transmit out of its original context, relevant preservation information about content objects comprising an AIP. Since a repository, following the OAIS reference model, usually provides resources with metadata container objects, the experiment performed an analysis on commonly used container formats, in order to enable the traceability of...

  8. MEASURING CONTENT QUALITY IN A PRESERVATION REPOSITORY: HATHITRUST AND LARGE-SCALE BOOK DIGITIZATION: Paper - iPres 2010 - Vienna

    Conway, Paul
    As mechanisms emerge to certify the trustworthiness of digital preservation repositories, no systematic efforts have been devoted to assessing the quality and usefulness of the preserved content itself. With generous support from the Andrew W. Mellon Foundation, the University of Michigan’s School of Information, in close collaboration with the University of Michigan Library and HathiTrust, is developing new methods to measure the visual and textual qualities of books from university libraries digitized by Google, Internet Archive, and others and then deposited for preservation. This paper describes a new approach to measuring quality in largescale digitization; namely, the absence of error relative to the expected uses of the deposited content. The paper specifies the design...

  9. DIGITAL PRESERVATION: THE TWITTER ARCHIVES AND NDIIPP: Paper - iPres 2010 - Vienna

    Campbell, Laura E.; Dulabahn, Beth
    On April 14, 2010, the Library of Congress and Twitter made the joint announcement that the Library would receive a gift of the archive of all public tweets shared through the service since its inception in 2006. The media and community response was tremendous, raising many questions about how the Library would be stewarding and providing access to the collection. There are many issues to consider, from the technical mechanisms of transfer to the Library and the ongoing updates to the archive, to curatorial policies, to planning for a new type of research access to a Library collection. The Twitter...

  10. ESA PLANS – A PATHFINDER FOR LONG TERM DATA PRESERVATION: Paper - iPres 2010 - Vienna

    Beruti, Vincenzo; Giaretta, David; Conway, Esther; Forcada, M.Eugenia; Albani, Mirko
    Digital preservation is difficult. The technical difficulties are the cause of much research. Other types of difficulty are those to do with organisational commitment, funding and context. With the increasing interest on global change monitoring, also the use and exploitation of long time series of Earth Observation (EO) data has been increasing systematically, calling for a need to preserve the EO data without time constrains. On the other hand: · Data archiving and preservation strategies are still mostly limited to the satellite lifetime and few years after. · The data volumes are increasing dramatically. · Archiving and data access technology are evolving rapidly. · EO data archiving strategies, if existing at all, are different for each EO...

  11. BABS2: A NEW PHASE, A NEW PERSPECTIVE IN DIGITAL LONG-TERM PRESERVATION – AN EXPERIENCE REPORT FROM THE BAVARIAN STATE LIBRARY: Paper - iPres 2010 - Vienna

    Beinert, Tobias; Brantl, Markus; Kugler, Anna
    BABS is an acronym for Library Archiving and Access System (Bibliothekarisches Archivierungs- und Bereitstellungssystem), which constitutes the infrastructure for digital long-term preservation at the Bavarian State Library (BSB). During the two-year project BABS2 funded by German Research Association (DFG) BSB focuses together with the Leibniz-Supercomputing Centre (LRZ) on advancing its organizational and technical processes under the aspect of trustworthiness according to the nestor criteria catalogue. Important achievements are e.g. framing an institutional policy for digital preservation including local, regional, national tasks of a large-scale research and archive library, conducting and evaluating a survey concerning the archiving requirements of all BSB...

  12. ADDING NEW CONTENT TYPES TO A LARGE-SCALE SHARED DIGITAL REPOSITORY: Paper - iPres 2010 - Vienna

    Beers, Shane; York, Jeremy; Mardesich, Andrew
    HathiTrust is a collaboration of universities working together to establish a repository that archives and shares their digitized collections. Initially, the Submission Information Packages (SIPs) deposited into HathiTrust were extremely uniform, being constituted primarily of books digitized by Google. HathiTrust’s ingest validation processes were correspondingly highly regular, designed to ensure that these SIPs met agreedupon qualities and specifications. As HathiTrust has expanded to include materials digitized from other sources, SIPs have become more varied in their content and specifications, introducing the need to make adjustments to ingest and validation routines. One of the primary sources of new SIPs is the Internet Archive, which has digitized a large number of public domain materials owned by HathiTrust...

  13. BUSINESS MODELS AND COST ESTIMATION: DRYAD REPOSITORY CASE STUDY: Paper - iPres 2010 - Vienna

    Beagrie, Neil; Eakin-Richards, Lorraine; Vision, Todd
    Data attrition compromises the ability of scientists to validate and reuse the data that underlie scientific articles. For this reason, many have called to archive data supporting published articles. However, few successful models for the sustainability of disciplinary data archives exist and many of these rely heavily on ephemeral funding sources. The Dryad project is a consortium of bioscience journals that seeks to establish a data repository to which authors can submit, upon publication, integral data that does not otherwise have a dedicated public archive. This archive is intended to be sustained, in part, through the existing economy of scholarly publishing....

  14. A REFERENCE ARCHITECTURE FOR DIGITAL PRESERVATION: Paper - iPres 2010 - Vienna

    Antunes, Gonçalo; Barateiro, José; Borbinha, José
    Apart from being a technological issue, digital preservation raises several organizational challenges. These challenges are starting to be addressed in the industrial design and e-Science domains, where emerging requirements cannot be addressed directly by OAIS. Thus, new approaches to design and assess digital preservation environments are required. We propose a Reference Architecture as a tool that can capture the essence of those emerging preservation environments and provide ways of developing and deploying preservation-enabled systems in organizations. This paper presents the main concepts from which a Reference Architecture for digital preservation can be built, along with an analysis of the environment surrounding a digital preservation system. We present a concrete Reference Architecture, consisting of a process to...

  15. DEVELOPING INFRASTRUCTURAL SOFTWARE FOR PRESERVATION: REFLECTIONS OF LESSONS LEARNED DEVELOPING THE PLANETS TESTBED: Paper - iPres 2010 - Vienna

    Aitken, Matthew Barr, Brian; Ross, Seamus; Lindley, Andrew; Barr, Matthew
    The Planets Testbed, a key outcome of the EC co-funded Planets project, is a web based application that provides a controlled environment where users can perform experiments on a variety of preservation tools using sample data and a standardised yet configurable experiment methodology. Development of the Testbed required the close participation of many geographically and strategically disparate organisations throughout the four-year duration of the project, and this paper aims to reflect on a number of key lessons that were learned whilst developing software for digital preservation experimentation. In addition to giving an overview of the Testbed and its evolution, this paper describes the iterative development process that was adopted, presents a set of...

  16. DEAL WITH CONFLICT, CAPTURE THE RELATIONSHIP: THE CASE OF DIGITAL OBJECT PROPERTIES: Paper - iPres 2010 - Vienna

    Dappert, Angela
    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 characterization service may extract the fontSize of a string, the preservation planning service may require the preservation of the text’s formatting. Additionally, a value for the same property may be obtained in various ways, sometimes resulting in different observed values. Furthermore, properties are not always equally applicable across different file formats. This report investigates where in these three situations relationships between properties need to...
