    3D Data Repository Features, Best Practices, and Implications for Preservation Models: Findings from a National Forum
    (ACRL, 2020) Hardesty, Juliet L.; Johnson, Jennifer; Wittenberg, Jamie; Hall, Nathan; Cook, Matt; Lischer-Katz, Zack; Xie, Zhiwu; McDonald, Robert; University Library
    This study identifies challenges and directions for 3D/VR repository standards and practices. As 3D technologies become more affordable and accessible, academic libraries need to implement workflows, standards, and practices that support the full lifecycle of 3D data. This study invited experts across several disciplines to analyze current national repository and preservation efforts. Outlined models provide frameworks to identify features, examine workflows, and determine implications of 3D data on current preservation models. Participants identified challenges for supporting 3D data, including intellectual property and fair use; providing repository system management beyond academic libraries; seeking guidance outside of academia for workflows to model.

    Exploring 3D Scanning for the Creation of Digital Cultural Heritage Collections
    (2015-10-26) Schaumberg, JD; Proctor, Anna; Johnson, Jennifer
    IUPUI University Library has been digitizing and providing access to community and cultural heritage collections since 2006. Varying formats include: audio, video, photographs, slides, negatives, and text (bound, loose). The library provides access to these collections using CONTENTdm. As 3D technologies become increasingly popular in libraries and museums, IUPUI University Library is exploring the workflows and processes as they relate to 3D artifacts. The library is collaborating with Online Resources Inc., a company that specializes in 3D technology to explore new ways to deliver content to a digital audience.

    Inclusion of 3D Artifacts into a Digital Library: Exploring Technologies and Best Practice Techniques
    (2016-11-08) Johnson, Jennifer; Proctor, Anna
    Advances in 3D technologies are providing libraries and museums the opportunity to capture 3D artifacts in digital formats. The Center for Digital Scholarship at IUPUI University Library is implementing workflows and determining best practices to incorporate 3D images into an already established digital library of community and cultural heritage collections.

    Monitoring, characterizing, and preventing microbial degradation of ignitable liquids on soil
    (2013) Turner, Dee Ann; Goodpaster, John V. (John Vincent); Michalski, Greg M.; Blacklock, Brenda J.; Siegel, Jay A.; Long, Eric C. (Eric Charles)
    Organic-rich substrates such as soil provide an excellent carbon source for bacteria. However, hydrocarbons such as those found in various ignitable liquids can also serve as a source of carbon to support bacterial growth. This is problematic for fire debris analysis as samples may be stored at room temperature for extended periods before they are analyzed due to case backlog. As a result, selective loss of key components due to bacterial metabolism can make identifying and classifying ignitable liquid residues by their chemical composition and boiling point range very difficult. The ultimate goal of this project is to preserve ignitable liquid residues against microbial degradation as efficiently and quickly as possible. Field and laboratory studies were conducted to monitor microbial degradation of gasoline and other ignitable liquids in soil samples. In addition to monitoring degradation in potting soil, as a worst case scenario, the effect of soil type and season were also studied. The effect of microbial action was also compared to the effect of weathering by evaporation (under nitrogen in the laboratory and by the passive headspace analysis of the glass fragments from the incendiary devices in the field studies). All studies showed that microbial degradation resulted in the significant loss of n-alkanes and lesser substituted alkylbenzenes predominantly and quickly, while more highly substituted alkanes and aromatics were not significantly affected. Additionally, the residential soil during the fall season showed the most significant loss of these compounds over the course of 30 days. To combat this problem, a chemical solution is to be immediately applied to the samples as they are collected. Various household and commercial products were tested for their efficacy at low concentrations to eliminate all living bacteria in the soil. Triclosan (2% (w/v) in NaOH) proved to be the most effective at preserving ignitable liquid residues for at least 30 days.

    Virtual Reality for Preservation: Production of Virtual Reality Heritage Spaces in the Classrooom
    (Council on Library and Information Resources, 2019) Wood, Zebulun M.; William, Albert; Copeland, Andrea; Human-Centered Computing, School of Informatics and Computing
    The Bethel AME Church was the oldest African American church in Indianapolis. In November 2016, the congregation moved out of downtown, and the building that had housed the congregation since 1869 was sold. It is now being redeveloped into a hotel. Through the Virtual Bethel project, faculty and students in the Media Arts and Science (MAS) program at Indiana University–Purdue University Indianapolis (IUPUI) created a 3D virtual space of the physical sanctuary to preserve the cultural heritage of Bethel. During its creation, Virtual Bethel served as a curricular and co-curricular experience for the undergraduate students in the 3D graphics and animation specialization within class N441 3D Team Production, which was co-taught by Albert William and Zebulun Wood. Virtual Bethel, finished in 2018, was the first historical and cultural preservation project that used VR within our class, program, school, and Indiana University (IU) campus. Users can interact with various types of primary sources (e.g., photographs, video, audio, text) to learn about the underrepresented history of African Americans associated with the church. Virtual Bethel was created in a series of classes within the MAS Program in the School of Informatics and Computing (SoIC), IUPUI. Methods of teaching a team of students to preserve historic spaces using VR are discussed, as are our philosophies toward productions when working with varying stakeholders’ priorities related to data preservation, asset preservation, and cultural preservation.
