Abstract: To digitally preserve and make historically significant buildings accessible, virtual museum tours and other customised applications are currently being developed at the great expense of time. This paper proposes a simple and handy workflow that makes it possible to automatically enrich any 3D model with freely available metadata about the site. Within the game engine Unity, an API searches internet database entries based on the coordinates of the cultural site. The search results (various media types) are reflected in the 3D model. Using Extended Reality, such an HBIM model can quickly be made available to the public.
