- Applying CoreTrustSeal Criteria as a Tool for Repository Development: A Collaborative ApproachKinnaman, Alex; Tuttle, James (2021-11-04)The Virginia Tech University Libraries (VTUL) pursued a CoreTrustSeal Certification and utilized the Requirements as a development tool for our Digital Libraries Platform. This presentation will describe the process of using the guidance in each Requirement to create a body of documentation and policies, and policy-driven service and software development.
- A Cloud-based Serverless Microservices Application for Digital PreservationChen, Yinlin; Kinnaman, Alex; Tuttle, James (2020-11-12)Virginia Tech University Libraries is developing a cloud-based, serverless, microservice application to support digital asset management, preservation, and access. This presentation will outline the balance of cost-effectiveness and creating a trustworthy platform while relying on the cloud.
- Making IT Work Part II: Integrating with IT to Develop a Sustainable Preservation SystemKinnaman, Alex; Menzies, Luke; Tuttle, James (2019-10-17)Preservation personnel and IT join forces in this presentation discussing strategies for the integration of workflows, resources, and a redistribution of job responsibilities to create a robust, sustainable preservation system at Virginia Tech University Libraries.
- Multi-tenancy Cloud Access and PreservationTuttle, James; Chen, Yinlin; Jiang, Tingting; Hunter, Lee; Waldren, Andrea; Ghosh, Soumik; Ingram, William A. (ACM, 2020-08)Virginia Tech Libraries has developed a cloud-native, microservervices-based digital libraries platform to consolidate diverse access and preservation infrastructure into a set of flexible, independent microservices in Amazon Web Services. We have been an implementer and contributor to various community digital library and repository projects including DSpace1, Fedora2, and Samvera3. However, the complexity and cost of maintaining disparate application stacks have reduced our capacity to build new infrastructure.
- A Multi-Tenancy Cloud-Native Digital Library PlatformChen, Yinlin; Ingram, William A.; Tuttle, James (2019-06-11)Virginia Tech Libraries presents our next generation digital library platform. Our design and implementation addresses the maintainability, sustainability, modularity, and scalability of a digital repository using a Cloud- native architecture, in which the entire platform is deployed in a cloud environment - Amazon Web Services (AWS). Our next-gen digital library eschews the old model of multiple siloed systems and embraces a common, sustainable infrastructure. This approach facilitates a more maintainable approach to managing and providing access to collections allowing us to focus on content and user experience. This platform is composed of a suite of microservices and cloud services. Microservices implemented as Lambda functions handle specific tasks and communicate with each other and other cloud services using lightweight asynchronous messaging. Cloud-native application development embodies the future of digital asset management and content delivery. Shared infrastructure throughout the stack and a clear demarcation between front- and back-end makes the platform more generalizable and supports independent replacement of components. We share our experiences and lessons learned developing this digital library platform, including architecture design, microservice implementation, cloud integration, best practices, and practical strategies and directions for developing a Cloud-native repository.
- North Carolina Geospatial Data Archiving Project Final ReportTuttle, James; Morris, Steve; Nagy, Zsolt (North Carolina State University Libraries, 2010-07-01)In October 2004 the NCSU Libraries and the NC Center for Geographic Information & Analysis entered into an agreement with the Library of Congress to pursue preservation of state and local digital geospatial data as part of the National Digital Information Infrastructure and Preservation Program (NDIIPP). The goal of the North Carolina Geospatial Data Archiving Project (NCGDAP) has been to inform development of a national digital preservation infrastructure through a “learning by doing” approach focused on identifying, acquiring, and preserving content within the context of the NC OneMap initiative and its framework of partnerships with state, local, and federal agencies. Although this three-year project was focused solely on the state of North Carolina, it is expected to serve as a demonstration project for data archiving and time series development elsewhere...
- A Partnership Framework for Geospatial Data Preservation in North CarolinaMorris, Steve; Tuttle, James; Essic, Jefferson (Johns Hopkins University Press, 2009-12-01)The North Carolina Geospatial Data Archiving Project (NCGDAP) is a joint project of the NC State University Libraries and the NC Center for Geographic Information and Analysis focusing on collection and preservation of state and local agency digital geospatial data resources. The project is being carried out in collaboration with the Library of Congress under the National Digital Information Infrastructure and Preservation Program (NDIIPP) in a partnership with the NC OneMap initiative, a statewide framework for data coordination and distribution. A core project objective is the engagement of established spatial data infrastructure in the challenge of long-term preservation of digital geospatial data. Key issues related to engaging spatial data infrastructure include initiation of data inventories, development of content exchange networks, cultivation of metadata standards and practices, and leveraging the experience of agencies that are already making efforts to retain historical data. The NCGDAP work triggered the creation of new data preservation partnerships both within the state and across a set of states that are participating in a new NDIIPP Multistate initiative.
- Preservation of state and local government digital geospatial data: The North Carolina geospatial data archiving projectMorris, S. P.; Tuttle, James; Farrell, R. (2006-12-01)The North Carolina Geospatial Data Archiving Project (NCGDAP) is a three-year joint effort of the North Carolina State University Libraries and the North Carolina Center for Geographic Information and Analysis focused on collection and preservation of digital geospatial data resources from state and local government agencies. NCGDAP is being undertaken in partnership with the Library of Congress under the National Digital Information Infrastructure and Preservation Program (NDIIPP). "Digital geospatial data" consists of digital information that identifies the geographic location and characteristics of natural or constructed features and boundaries on the earth. Such data resources include geographic information systems (GIS) data sets, digitized maps, remote sensing data resources such as digital aerial photography, and tabular data that are tied to specific locations. State and local data resources, which are in general of greater detail and more current than data available from federal agencies, are generally not addressed by data archiving efforts at the federal level.
- Scaling IIIF Image Tiling in the CloudChen, Yinlin; Ghosh, Soumik; Jiang, Tingting; Tuttle, James (2020-02-17)The International Archive of Women in Architecture, established at Virginia Tech in 1985, collects books, biographical information, and published materials from nearly 40 countries that are divided into around 450 collections. In order to provide public access to these collections, we built an application using the IIIF APIs to pre-generate image tiles and manifests which are statically served in the AWS cloud. We established an automatic image processing pipeline using a suite of AWS services to implement microservices in Lambda and Docker. By doing so, we reduced the processing time for terabytes of images from weeks to days. In this article, we describe our serverless architecture design and implementations, elaborate the technical solution on integrating multiple AWS services with other techniques into the application, and describe our streamlined and scalable approach to handle extremely large image datasets. Finally, we show the significantly improved performance compared to traditional processing architectures along with a cost evaluation.
