    Developing Library Strategy for 3D and Virtual Reality Collection Development and Reuse: An IMLS National Digital Platform Project
    Hall, Nathan; Hardesty, Juliet; Cook, Robert; McDonald, Robert H.; Lischer Katz, Zack; Wittenbert, Jaime; Carlisle, Tara; Johnson, Jennifer; Griffin, Julie; Xie, Zhiwu; Ogier, Andrea (2018)
    These are the preliminary and full proposals for an IMLS grant to develop a white paper (to be added here in late 2018) to host three national forums of invited experts to support library adoption of 3D and virtual reality (VR) services. The forums were hosted by Virginia Tech University Libraries, Indiana University Libraries, and the University of Oklahoma Libraries. Each forum covered a different 3D and VR theme: content creation and publishing, visualization and analysis, and repository practice and standards. Lower costs and greater computational power have made 3D and VR technologies financially realistic for a broad variety of institutions. Many academic libraries have developed archives for other forms of research data, but there is an absence of standards and best practices for producing, managing, and preserving 3D and VR content. This gap is an information management problem suited to the strengths of libraries and can benefit librarians and researchers alike across institutions.

    Evaluating Cost of Cloud Execution in a Data Repository
    Xie, Zhiwu; Chen, Yinlin; Griffin, Julie; Walters, Tyler (ACM, 2016-06)
    In this paper, we utilize a set of controlled experiments to benchmark the cost associated with the cloud execution of typical repository functions such as ingestion, fixity checking, and heavy data processing. We focus on the repository service pattern where content is explicitly stored away from where it is processed. We measured the processing speed and unit cost of each scenario using a large sensor dataset and Amazon Web Services (AWS). The initial results reveal three distinct cost patterns: 1) spend more to buy up to proportionally faster services; 2) more money does not necessarily buy better performance; and 3) spend less, but faster. Further investigations into these performance and cost patterns will help repositories to form a more effective operation strategy.

    Hubs and centers as transitional change strategy for library collaboration
    Griffin, Julie; Mathews, Brian; Walters, Tyler (International Association of Scientific and Technological University Libraries, 2013-04-18)
    Libraries of science and technology universities worldwide are adapting to a changing environment where cyberinfrastructure, eResearch, and new technology-intensive approaches to teaching and learning are transforming the very nature of universities. While many have adopted new technologies and the resources and expertise to manage them, this is only an initial step. Libraries are experimenting with organizational models that will transform their work capacity and expertise. The goal of these libraries is being an entity that feeds and produces collaborative synergies between faculty, students, information professionals, and technologists. Virginia Tech, among the top research universities in the United States, and its constituent libraries are adopting a unique organizational change strategy that implements eScience and cyberlearning roles. This two-part strategy begins with establishing ‘hubs’. The hubs are collaborative, crossdepartmental groups in which library employees of varying backgrounds and skills come together on common themes of strategic importance. The hubs act in one sense as a ‘research & development lab’ to explore, imagine, and brainstorm new library initiatives as well as engender deeper understandings of the university’s core academic enterprise. They also are a ‘strike force’ that implements, supports, and assesses emerging library roles in relation to the institution’s academic mission. In these ways, hubs also create learning and scholarship opportunities for their participants beyond the individual task-oriented projects. The second part of this strategy involves the establishment of research and service centers. At Virginia Tech, these are the Center for Innovation in Learning (CIL) and the Center for Digital Research and Scholarship (CDRS). These centers are designed to incubate and sustain new collaborative synergies between libraries, researchers, instructors, and learners by providing expertise, resources, and new infrastructures to address specific academic research-based needs. The centers become focal points for library action, focused on learning and research activities within other university entities. Benefits to library employees come in the form of scholarship and research with potential for collaboration and new initiatives as relationships grow among project participants. The authors will discuss transformational aspects of the change management model, with lessons from their early experiences. They also will discuss how the model can be adapted by other libraries of science and technology-centered universities.

    Library-as-Publisher: Capacity Building for the Library Publishing Subfield
    Skinner, Katherine; Lippincott, Sarah; Griffin, Julie; Walters, Tyler (Michigan Publishing, University of Michigan Library, 2014)
    This essay provides a brief history of publisher training and uses this context to think about how and where library publishers may engage in capacity building to inform and train this growing publishing subfield. Throughout the essay, we integrate findings from a series of interviews conducted by the authors with 11 industry leaders from several publishing sectors, including university presses, library publishers, and commercial publishers. We conclude with recommendations for pathways forward, focusing on seven key areas in which library publishers need additional training opportunities. This essay focuses primarily on North American activities.

    On-Demand Big Data Analysis in Digital Repositories
    Xie, Zhiwu; Chen, Yinlin; Jiang, Tingting; Griffin, Julie; Walters, Tyler; Tarazaga, Pablo Alberto; Kasarda, Mary E. (Springer International Publishing, 2015-12-18)
    We describe a use and reuse driven digital repository integrated with lightweight data analysis capabilities provided by the Docker framework. Using building sensor data collected from the Virginia Tech Goodwin Hall Living La- boratory, we perform evaluations using Amazon EC2 and Container Service with a Fedora 4 repository backed with storage in Amazon S3. The results con- firm the viability and benefits of this approach.

    Public Access: A Driver for Preservation and Discovery of Datasets at a US Land-Grant Institution
    Ogier, Andrea; Petters, Jonathan L.; Pannabecker, Virginia; Settledge, Robert; Grant, Elizabeth J.; Harden, Samantha M.; Griffin, Julie; Walters, Tyler (2019-08-24)
    Public access to federally funded research data ensures preservation and discovery of datasets to promote translation of research evidence into meaningful outcomes. However, historical policy and concerns regarding making data publicly accessible impede realization of implementing public access to data. These concerns include worry over the treatment of intellectual property, the cost (in time and money) of making research publicly accessible, and the danger of accidentally releasing human subjects data. To overcome these issues, a Public Access to Data Committee was established at a public university in rural southwest Virginia. In this paper we review the history of federal public access provisions, share goals, and describe the committee’s process to ultimately engage faculty and administrators in this critical link from research to practice.

    Towards Use And Reuse Driven Big Data Management
    Xie, Zhiwu; Chen, Yinlin; Griffin, Julie; Walters, Tyler; Tarazaga, Pablo Alberto; Kasarda, Mary E. (2015-06-03)
    We propose a use and reuse driven big data management approach that fuses the data repository and data processing capabilities in a co-located, public cloud. It answers to the urgent data management needs from the growing number of researchers who don’t fit in the big science/small science dichotomy. This approach will allow researchers to more easily use, manage, and collaborate around big data sets, as well as give librarians the opportunity to work alongside the researchers to preserve and curate data while it is still fresh and being actively used. This also provides the technological foundation to foster a sharing culture more aligned with the open source software development paradigm than the lone-wolf, gift-exchanging small science sharing or the top-down, highly structured big science sharing. To materialize this vision, we provide a system architecture consisting of a scalable digital repository system coupled with the co-located cloud storage and cloud computing, as well as a job scheduler and a deployment management system. Motivated by Virginia Tech’s Goodwin Hall instrumentation project, we implemented and evaluated a prototype. The results show not only sufficient capacities for this particular case, but also near perfect linear storage and data processing scalabilities under moderately high workload.

    VTechData: An Institutional Data Repository
    Xie, Zhiwu; Griffin, Julie; Chen, Yinlin; Jiang, Tingting; Brittle, Collin; Mather, Paul (2016-06-14)
    We introduce VTechData, a Sufia/Fedora based institutional repository specifically implemented to meet the needs of research data management at Virginia Tech. Despite the rapid maturity of Hydra and Fedora code bases, the gaps between the released packages and a launched production­level service are still many and far from trivial. In this presentation we describe the strategy and efforts through which these gaps were filled and lessons learned in the process of creating our first Hydra/Sufia­based repository.
