Creating Trust Relationships for Distributed Digital Preservation Federations
Walters, Tyler; McDonald, Robert H. (iPRES 2008: The Fifth International Conference on Preservation of Digital Objects, 2008)
The authors outline a model for digital preservation federation based upon several existing models including the U.S. Federal Reserve Bank regional governance model and its similarities to successful large-scale redundant internet networks. In addition other trust models will be examined including Maister, Green, and Galford (2000), Holland and Lockett (1998), and Ring and Van de Ven (1994). These models provide key frameworks for understanding how trust can be enabled among federated but independent 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.
Foundations of Digital Curation
Walters, Tyler (Northeast Document Conservation Center. Digital Directions conference., 2012-06-13)
This track-opening presentation looks at the evolution of digital curation as an approach and perspective on cultural institutions’ value-added services in information management. In particular, the presenter comments on digital curation’s antecedents, related definitions, and why institutions should engage in digital curation. After a high-level review of the stages articulated in the Digital Curation Centre’s Lifecycle Model, Walters delves into institutional roles, responsibilities, and job models to carry out curation, and the multi-institutional collaborative strategies he posits are necessary to achieve large-scale digital curation.
The Future of Knowledge Creation and Production in University Research Programs and Their Effect on University Libraries
Walters, Tyler (2014-04-11)
The dissertation presents possible future directions for research programs at U.S. universities and their effects on the organization of universities and their libraries. The investigator posits four original scenarios produced for this study that describe Grand Challenge-level research program development in U.S. research universities. The scenarios articulate how these universities’ research enterprises might take part in an emerging global research ecosystem that is being shaped by economic, political, cultural, and technological forces. The university managerial leaders involved in research administration can utilize the scenarios in planning for how they might respond to certain forces and drivers effecting the development of their research programs. The leaders, in turn, may understand better the decisions to be made in moving a university forward strategically to realize its goals in the global research environment. The study also examines how the libraries of the participating universities may evolve based on scenario 1, “Thriving interdisciplinary research, solving global Grand Challenges,” which is the scenario most favored by the research directors. Four case studies are offered, produced from interviews with the case library directors. They highlight the directors’ approaches to managerial leadership and organizational culture change with a goal of producing a library that is relevant and vital to its university’s role in the developing global research ecosystem. New library roles are articulated, focusing on managing research outputs, supporting research and scholarly processes, developing technologies and content, and partnering with researchers on research teams and as consultants. The case studies reveal that the more vigorously adapting libraries are differentiated from the lesser adapting libraries according to the level of resources available, technology infrastructures in place, and strategic partnerships created and maintained. This study emphasizes the role of research and library directors in developing and communicating strategic directions to effect change in a U.S. university. Each library director’s response to the favored scenario gives insight into how libraries may approach transformation in the face of momentous change in the university research enterprise due to external drivers. Examining the impact of these drivers through scenarios developed from an institutional perspective aids administrators in planning for how their universities will respond.
The Future Role of Publishing Services in University Libraries
Walters, Tyler (The Johns Hopkins University Press, 2012)
This study explores possible futures for university-based library publishing services (LPS) and uses scenario planning as its research method. The study posits that the major force in developing LPS is the level of funding from the host university, with the most uncertain factor being whether faculty will adopt LPS. The study participants comprised university library directors, library managers responsible for publishing services, and library association personnel and consultants involved in publishing. Many participants saw collaborating with multiple libraries and other stakeholder organizations to establish publishing cooperatives as essential. Issues discussed include whether university libraries will embrace this role, faculties’ level of satisfaction with existing services, divergent disciplinary experiences, opportunism as a mechanism to develop services, technology challenges, international dynamics, traditional vs. new forms of scholarly publishing, and publishing cost considerations.
Global Systems Science: Library Space and Services
Walters, Tyler (Virginia Tech Libraries, 2018-03)
The VT Libraries imagine a commons in the Global Systems Science (GSS) building that support research and education and serves as an intellectual ecotone: a zone where several different ecosystems overlap, creating an environment for diverse and complex exchange dynamics. We see a science research commons as a similar system, bringing together research and education activities across a wide array of disciplines, programs, resources, and technologies in the GSS building. Librarians will serve a lead role in nurturing interdisciplinary dynamics, the exchange and transmission of ideas, and creation of new knowledge products.
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.
The Insitutional Repository's Role in Preserving Research Data
Xie, Zhiwu; McMillan, Gail; Walters, Tyler (Virginia Tech, 2012-07-25)
In recent years, many funding agencies have started to require long-term preservation and open access to research data. While most research universities have already run their own institutional repositories (IR), it's not clear what role the IR can play in managing these data. Unlike the textual and even multimedia contents currently archived by the conventional IR, research data are much more diverse in terms of format, metadata, storage, rendering, and access requirements. The differences between the geospatial data, astronomical observation data, DNA sequencing data, and computational fluid dynamics simulation data can be so large as to deserve their own disciplinary data repositories. A disciplinary repository can customize its structure and functionality for a specific type of data, a luxury not available to the general-purpose IR. On the other hand, the IR is uniquely positioned to manage the research data. The university provides the IT infrastructure where most of the data are initially generated, processed, stored, and managed. As part of the IT infrastructure, the IR usually presents the lowest migration barrier and also the cheapest cost for data created within the same institution. In order to meet the data managing challenges, we therefore must clearly define the core functionality an IR must provide during the lifecycle of the research data, which may include: - Closely integrate the IR with the university's IT infrastructure to allow easy deposit and access control - Provide the baseline storage needs, which may be further differentiated by the usage pattern to lower the cost - Act as a metadata hub that not only can understand various disciplinary metadata, but can also translate them into more widely understood terms for easy discovery and access - Facilitate reuse and preservation by at least maintaining the preservation metadata that document the environment where the data originally lived - Provide programming interfaces to facilitate the data visualization, presentation, and usage from external services - Provide data exchange interfaces to various disciplinary data repositories Virginia Tech is working towards building its IR, VTechWorks, as an exemplary general-purpose repository that fulfills these data management roles.

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.
Native Voices: Native Peoples' Concepts of Health and Illness - Opening Ceremony
(Virginia Tech. University Libraries, 2016-09-16)
This is the opening ceremony for the Native Voices exhibit. The exhibit examines concepts of health and medicine among contemporary American Indian, Alaska native, and Native Hawai'ian people. The traveling exhibition, produced by the National Library of Medicine, features interviews and works from native people living on reservations, in tribal villages, and in cities. topics include: Native views of land, food, community, earth/nature, and spirituality as they relate to Native Health; the relationship between traditional healing and Western medicine in native communities; economic and cultural issues that affect the health of Native communities; efforts by Native communities to improve health conditions; and the role of Native Americans in military service and healing support for returning Natives veterans.
New Roles for New Times: Digital Curation for Preservation
Walters, Tyler; Skinner, Katherine (Association of Research Libraries, 2011-03)
Digital curation refers to the actions people take to maintain and add value to digital information over its lifecycle, including the processes used when creating digital content. Digital preservation focuses on the “series of managed activities necessary to ensure continued access to digital materials for as long as necessary.” In this report, we highlight the intersection of these actions, specifically focusing on how digital curation must facilitate the preservation of our shared digital memory.
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.

The 2022 Open Access Forum features a presentation by Heather Joseph on the recent OSTP memo (aka Nelson memo) requiring immediate access to research funded by federal agencies, with a Q&A afterward. Short introductions to open access, open data, and open educational resources follow.
Open Access Week 2020 Keynote: Counting what counts in recruitment, promotion and tenure
Gadd, Elizabeth; Ewing, E. Thomas; Finkielstein, Carla V.; Gill, Bikrum Singh; Johnson, Sylvester; Walters, Tyler (Virginia Tech. University Libraries, 2020-10-20)
Open Access Week 2020 keynote speaker, Elizabeth (Lizzie) Gadd, Research Policy Manager (Publications) at Loughborough University in the UK, gives a talk about how what we reward through recruitment, promotion and tenure processes is not always what we actually value about research activity. The talk explores how we can pursue value-led evaluations - and how we can persuade senior leaders of their benefits. The keynote talk is followed by a panel discussion with faculty members at Virginia Tech: Thomas Ewing (Associate Dean for Graduate Studies and Research and Professor of History), Carla Finkielstein (Associate Professor of Biological Sciences), Bikrum Gill (Assistant Professor of Political Science), and Sylvester Johnson (Professor and Director of the Center for Humanities. The panel is moderated by Tyler Walters (Dean, University Libraries). The slides from this presentation are in Loughborough University's repository under a CC BY-NC-SA 4.0 license.
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.
Statement of Achievements
Walters, Tyler (Virginia Tech, 2017-03)
Introduction: The following is a summary of my leadership and achievements as the Dean of University Libraries during the review period, March 2011 to February 2017. The Libraries have undergone tremendous change, perhaps as significant and as rapid a change as any university research library in the country. Through my leadership, we have built a nimble and flexible library system; one that anticipates the needs of the university community, shows it what is possible, and introduces new approaches regarding information, data, and knowledge-building. While these activities reflect my own commitment and dedication, I recognize that my achievements are organizational successes made possible by the Libraries’ faculty and staff and the internal and external partners with whom we work. Without their adoption and sharing in our contemporary vision and strategies, and engaging in the enormous transitions undertaken, I would have very few achievements to report. For their interest, energy, and commitment to growing a dynamic and vibrant library, I am very grateful.
