Open Problems In 3d Model And Data Management

In interdisciplinary, cooperative projects that involve different representations of 3D models (such as CAD data and simulation data), a version problem can occur: different representations and parts have to be merged to form a holistic view of all relevant aspects. The individual partial models may be exported by and modified in different software environments. These modifications are a recurring activity and may be carried out again and again during the progress of the project.This position paper investigates the version problem; furthermore, this contribution is intended to stimulate discussion on how the problem can be solved.
