"Out There," In Here: Preservation Strategies for Multimodal Cultural Heritage in 3D and XR

Abstract

This paper presents Out There, a multimodal, interdisciplinary project that captures 2D photography, 3D models, Gaussian splats, volumetric video, and oral histories to document the work of a legally blind sculptor in a remote outdoor setting. Designed to serve both as a digital preservation strategy and a collaborative framework, the project examines challenges such as file format volatility, interoperability, metadata standards, and storage demands. Drawing on evolving best practices and preservation models, we propose strategies for maintaining long-term access to complex digital assets while centering collaboration with artists and domain experts. This work-in-progress highlights both the potential and the limitations of current 3D/XR preservation efforts and contributes a replicable model for cultural heritage practitioners working with similarly layered digital projects.
