Posted in Digital Repositories, DSpace, Institutional Repositories, Open Access on March 3rd, 2014

Mini Vamadevan Pillai has self-archived "A DSpace Mobile Theme for San Diego State University."

Here's an excerpt:

This thesis is an attempt to install and customize a DSpace mobile theme for San Diego State University. The work also includes development of additional features like adding navigational bars, adding administrative login capabilities, accessing administrative navigational panel via mobile theme. The mobile theme supports other features like search, advanced search, recent submissions, submissions and workflow. With the widespread use of mobile telephony, providing a mobile theme for SDSU DSpace will reach out to faculty and other interested parties.

      "Have Digital Repositories Come of Age? The Views of Library Directors"

      Posted in Digital Repositories, Institutional Repositories, Open Access on January 20th, 2014

      David Nicholas et al. have published "Have Digital Repositories Come of Age? The Views of Library Directors" in Webology.

      Here's an excerpt:

      This survey of approximately 150 repositories assessed the achievements, impact, and success of digital repositories. Results show that while the size and use of repositories has been relatively modest, almost half of all institutions either have, or are planning, a repository mandate requiring deposit and small gains have been made in raising the profile of the library within the institution. Repositories, then, have made a good deal of progress, but they have not quite come of age.

        "Flexible and Extensible Digital Object and Repository Architecture (FEDORA)"

        Posted in Digital Repositories, Fedora, Institutional Repositories on December 6th, 2013

        Sandra Payette and Carl Lagoze have self-archived "Flexible and Extensible Digital Object and Repository Architecture (FEDORA)."

        Here's an excerpt:

        We describe a digital object and repository architecture for storing and disseminating digital library content. The key features of the architecture are: (1) support for heterogeneous data types; (2) accommodation of new types as they emerge; (3) aggregation of mixed, possibly distributed, data into complex objects; (4) the ability to specify multiple content disseminations of these objects; and (5) the ability to associate rights management schemes with these disseminations. This architecture is being implemented in the context of a broader research project to develop next-generation service modules for a layered digital library architecture.

          "Cultures of Access: Differences in Rhetoric around Open Access Repositories in Africa and the United States and Their Implications for the Open Access Movement"

          Posted in Digital Repositories, Institutional Repositories, Open Access, Self-Archiving on December 5th, 2013

          Natalia T. Bowdoin has self-archived "Cultures of Access: Differences in Rhetoric around Open Access Repositories in Africa and the United States and Their Implications for the Open Access Movement."

          Here's an excerpt:

          For this study I examined the rhetoric used by OA institutional repositories and what this rhetoric may say about different "cultures of OA." I conducted textual analysis of 46 websites of OA repositories in the United States and 14 Sub-Saharan African nations. Analysis of the specific rhetoric used to present the OA repositories reveals differing views on the importance of OA in terms of cultural ideas about information control, access to information, and social capital.

            "Open-Access Repositories Worldwide, 2005-2012: Past Growth, Current Characteristics and Future Possibilities"

            Posted in Digital Repositories, Disciplinary Archives, Institutional Repositories, Open Access on October 23rd, 2013

            Stephen Pinfield et al. have self-archived "Open-Access Repositories Worldwide, 2005-2012: Past Growth, Current Characteristics and Future Possibilities" in White Rose Research Online.

            Here's an excerpt:

            This paper reviews the worldwide growth of open-access (OA) repositories, December 2005 to December 2012, using data collected by the OpenDOAR project. It shows that initial repository development was focused on North America, Western Europe and Australasia, particularly the USA, UK, Germany and Australia. Soon after, Japan increased its repository numbers. Since 2010, other geographical areas and countries have seen repository growth, including East Asia (especially Taiwan), South America (especially Brazil) and Eastern Europe (especially Poland). During the whole period, countries such as France, Italy and Spain have maintained steady growth, whereas countries such as China and Russia have experienced relatively low levels of growth. Globally, repositories are predominantly institutional, multidisciplinary and English-language-based. They typically use open-source OAI-compliant repository software but remain immature in terms of explicit licensing arrangements. Whilst the size of repositories is difficult to assess accurately, the available data indicate that a small number of large repositories and a large number of small repositories make up the repository landscape. These trends and characteristics are analyzed using Innovation Diffusion Theory (IDT) building on previous studies. IDT is shown to provide a useful explanatory framework for understanding repository adoption at various levels: global, national, organizational and individual. Major factors affecting both the initial development of repositories and their take up by users are identified, including IT infrastructure, language, cultural factors, policy initiatives, awareness-raising activity and usage mandates. It is argued that mandates in particular are likely to play a crucial role in determining future repository development.

              "Fedora Commons with Apache Hadoop: A Research Study"

              Posted in Digital Repositories, Institutional Repositories on October 15th, 2013

              Mohamed Mohideen Abdul Rasheed have published "Fedora Commons with Apache Hadoop: A Research Study" in the latest issue of Code4Lib Journal.

              Here's an excerpt:

              The Digital Collections digital repository at the University of Maryland Libraries is growing and in need of a new backend storage system to replace the current filesystem storage. Though not a traditional storage management system, we chose to evaluate Apache Hadoop because of its large and growing community and software ecosystem. Additionally, Hadoop's capabilities for distributed computation could prove useful in providing new kinds of digital object services and maintenance for ever increasing amounts of data. We tested storage of Fedora Commons data in the Hadoop Distributed File System (HDFS) using an early development version of Akubra-HDFS interface created by Frank Asseg. This article examines the findings of our research study, which evaluated Fedora-Hadoop integration in the areas of performance, ease of access, security, disaster recovery, and costs.

                "Who and What Links to the Internet Archive"

                Posted in Digital Curation & Digital Preservation, Digital Repositories on September 19th, 2013

                Yasmin AlNoamany, Ahmed AlSum, Michele C. Weigle, and Michael L. Nelson have self-archived "Who and What Links to the Internet Archive" in arXiv.org.

                Here's an excerpt:

                The Internet Archive's (IA) Wayback Machine is the largest and oldest public web archive and has become a significant repository of our recent history and cultural heritage. Despite its importance, there has been little research about how it is discovered and used. Based on web access logs, we analyze what users are looking for, why they come to IA, where they come from, and how pages link to IA. We find that users request English pages the most, followed by the European languages. Most human users come to web archives because they do not find the requested pages on the live web. About 65% of the requested archived pages no longer exist on the live web. We find that more than 82% of human sessions connect to the Wayback Machine via referrals from other web sites, while only 15% of robots have referrers. Most of the links (86%) from websites are to individual archived pages at specific points in time, and of those 83% no longer exist on the live web.
