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.
