In this paper, we describe a repository for architectural 3D-CAD models which is currently set up at the German National Library of Science and Technology (TIB), Hannover, as part of the larger German PROBADO digital library initiative: The proposed PROBADO-framework is integrating different types of multimedia content-repositories and adding features available in text-based digital libraries. A workflow for automated content-based data analysis and indexing is proposed.
