Advancements in 3D Heritage Data Aggregation and Enrichment in Europe: Implications for Designing the Jena Experimental Repository for the DFG 3D Viewer

Since the 2010s, various national and pan-European public infrastructures have been emerging around aggregation, viewing, and 3D heritage model collection. The purpose of this article is to focus on the current state and ecosystem for 3D models in Europe through (a) a review of published studies on users, objects, and demands (b) and an overview of the ecosystem for 3D heritage data. As part of the German distributed infrastructure, the DFG 3D Viewer Jena experimental repository serves as a testbed for technology prototyping and testing. Based on the findings of the European ecosystem, we used this repository to test a prototypic approach to (c) acquiring 3D data from multiple sources, (d) enriching data quality, and (e) enabling indexing, searching, and viewing functionalities.
