||3D documents are an indispensable data type in many im-
portant application domains such as Computer Aided De-
sign, Simulation and Visualization, and Cultural Heritage,
to name a few. The 3D document type can represent arbi-
trarily complex information by composing geometrical, topo-
logical, structural, or material properties, among others. It
often is integrated with meta data and annotation by the
various application systems that produce, process, or con-
sume 3D documents.
We argue that due to the inherent complexity of the 3D
data type in conjunction with and imminent pervasive usage
and explosion of available content, there is pressing need to
address key problems of the 3D data type. These problems
need to be tackled before the 3D data type can be fully
supported by Digital Library technology in the sense of a
generalized document, unlocking its full potential. If the
problems are addressed appropriately, the expected benefits
are manifold and may lead to radically improved production,
processing, and consumption of 3D content.
