Towards Repository Preservation Services. Final Report from the JISC Preserv 2 Project

Posted in Cloud Computing/SaaS, Digital Curation & Digital Preservation, Digital Repositories, EPrints, Fedora, Institutional Repositories on October 28th, 2009

Steve Hitchcock, David Tarrant, and Les Carr have self-archived Towards Repository Preservation Services. Final Report from the JISC Preserv 2 Project in the ECS EPrints Repository.

Here's the abstract:

Preserv 2 investigated the preservation of data in digital institutional repositories, focussing in particular on managing storage, data and file formats. Preserv 2 developed the first repository storage controller, which will be a feature of EPrints version 3.2 software (due 2009). Plugin applications that use the controller have been written for Amazon S3 and Sun cloud services among others, as well as for local disk storage. In a breakthrough application Preserv 2 used OAI-ORE to show how data can be moved between two repository softwares with quite distinct data models, from an EPrints repository to a Fedora repository. The largest area of work in Preserv 2 was on file format management and an 'active' preservation approach. This involves identifying file formats, assessing the risks posed by those formats and taking action to obviate the risks where that could be justified. These processes were implemented with reference to a technical registry, PRONOM from The National Archives (TNA), and DROID (digital record object identification service), also produced by TNA. Preserv 2 showed we can invoke a current registry to classify the digital objects and present a hierarchy of risk scores for a repository. Classification was performed using the Preserv2 EPrints preservation toolkit. This 'wraps' DROID in an EPrints repository environment. This toolkit will be another feature available for EPrints v3.2 software. The result of file format identification can indicate a file is at risk of becoming inaccessible or corrupted. Preserv 2 developed a repository interface to present formats by risk category. Providing risk scores through the live PRONOM service was shown to be feasible. Spin-off work is ongoing to develop format risk scores by compiling data from multiple sources in a new linked data registry.

    ETD Self-Archiving Tools: ICE-TheOREM Final Report

    Posted in Digital Repositories, DSpace, Electronic Theses and Dissertations (ETDs), EPrints, Fedora, Institutional Repositories, Self-Archiving on October 12th, 2009

    JISC has released the ICE-TheOREM Final Report.

    Here's an excerpt:

    ICE-TheOREM was a project which made several important contributions to the repository domain, promoting deposit by integrating the repository with authoring workflows and enhancing open access by prototyping new infrastructure to allow fine-grained embargo management within an institution without impacting on existing open access repository infrastructure.

    In the area of scholarly communications workflows, the project produced a complete end-to-end demonstration of eScholarship for word processor users, with tools for authoring, managing and disseminating semantically-rich ETD (Electronic Theses and Dissertations) documents fully integrated with supporting data. This work is focused on theses, as it is well understood that early career researchers are the most likely to lead the charge in new innovations in scholarly publishing and dissemination models.

    The authoring tools are built on the ICE content management system, which allows authors to work within a word processing system (as most authors do) with easy-to-use toolbars to structure and format their documents. The ICE system manages both small data files and links to larger data sets. The result is research publications which are available not just as paper-ready PDF files but as fully interactive semantically aware web documents which can be disseminated via repository software such as ePrints, DSpace and Fedora as complete supported web-native and PDF publications.

        SWORD2 Project Final Report

        Posted in Digital Repositories, DSpace, EPrints, Fedora, Institutional Repositories, Self-Archiving on October 5th, 2009

        JISC has released SWORD2 Project Final Report.

        Here's an excerpt:

        The SWORD vision is about 'lowering the barriers to deposit', primarily for depositing content into repositories, and additionally, for depositing into any system which may wish to receive content from remote sources. The SWORD protocol defines a standard mechanism for depositing into repositories and other systems. The project and protocol were developed because there was previously no standardised way of doing this. A standard deposit interface allows repository services to be built that can offer functionality such as deposit from multiple locations, e.g. disparate repositories, desktop drag'n'drop tools, or from within standard office applications. SWORD can also facilitate deposit to multiple repositories, increasingly important for depositors who wish to deposit to funder, institutional or subject repositories. There are many other possibilities, including migration of content between repositories and transfer to preservation services. In addition to refining the existing SWORD application profile, the SWORD2 project has developed a number of tools and services to demonstrate these possibilities. It has also been pro-active in promoting SWORD and encouraging uptake within other repositories, services and tools, notably with its adoption into the Microsoft Article Authoring Add-in for Word 2007 and with the new Microsoft Zentity repository system .

        The core aims of the project were to update the SWORD Protocol, the SWORD repository code libraries in the DSpace, Fedora, EPrints and Intrallect repositories, and the existing reference demonstrators. A Facebook application and validator have also been developed. Advocacy efforts include an e-learning case study, a briefing paper, a new SWORD website, and a range of additional dissemination activities, including conference papers, presentations, demonstrations and workshops at a number of national and international conferences and meetings.

          Enhanced Ingest to Digital E-Research Repositories: Final Report

          Posted in Digital Repositories, Fedora, Institutional Repositories, Metadata, Self-Archiving on September 29th, 2009

          JISC has released Enhanced Ingest to Digital E-Research Repositories: Final Report.

          Here's an excerpt:

          The project developed a demonstrator that implemented an enhanced deposit and ingest process to a digital repository based on Fedora. The process incorporates the SWORD API for deposit, and accepts deposits that contain multiple files (packaged as a zip file). The workflow performs preservation actions (e.g. capturing PREMIS metadata, format migration), extraction of resource discovery metadata (for text-based formats such as PDF, MS Word, HTML), and capture of publisher self-archiving policies (for post-prints). The resources are ingested into the repository following an atomistic model—individual files and directories correspond to individual digital objects, and relationships between them (i.e. the membership relation between files/directories) are represented as RDF statements. The workflow was constructed from a variety of components developed by other projects.

                JISC Final Report—CTREP, Cambridge TETRA Repositories Enhancement Project

                Posted in Digital Repositories, DSpace, Fedora, Institutional Repositories, Learning Objects on July 23rd, 2009

                JISC has released JISC Final Report—CTREP, Cambridge TETRA Repositories Enhancement Project .

                Here's an excerpt:

                CTREP created a connector between an Institutional VRE and an Institutional Repository. It is designed to be reusable in a number of different institutions where policy on deposit varies by means of a flexible deposit configuration system. In the process of executing the project:

                • the various stakeholders came to understand institutional cultural differences and address them in such a way that recent projects with a strong Repository and research dissemination/visualisation aspect have been more joined up than would previously have been possible
                • we developed an approach to policy expression designed both to avoid creating unnecessary tension within the institution during its development, and also to be authorable by a wide range of individuals
                • we have sought to record and capture lessons learnt (based, in part on case studies) for future institutionalisation projects
                • we developed a number of techniques which allowed apparent barriers to integration to be overcome by technical-architectural tools
                • we open-sourced the integration
                • we modified our approach to metadata/data binding in light of community feedback and developed a spreadsheet-based automated approach with which contributors felt comfortable, but which required a number of technical obstacles to be overcome through the use of creative programming techniques.
