Digital dossiers provide an efficient means to present cultural heritage on the web, including media-rich representations of artworks as well as 3D models of artwork installations and the information needed for understanding the artwork in the context of its production and (re-)installation. Digital dossiers provide support for navigating the information space by means of concept graphs. Instead of presenting a complete view of the hierarchy, the concept graph shows only a subset of the information, and allows in this way for arbitrarily complex information structures.
