Although semantic linking for heterogeneous data about the building is already established in container-based environments-such as Common Data Environments, Digital Twins and Digital Archives-the spatial component has been neglected. In the field of computer graphics, however, the principle of the scene graph has already been established for the spatial relationship. Nevertheless, spatial linking can help establish a context between files and make it machine-readable to evaluate this context efficiently. This paper investigates to what extent scene graphs can be used to link heterogeneous files spatially. Based on current workflows and research, objectives for a potential file-level scene graph framework are provided. An example implementation for these objectives is shown in a Linked Data scenario.
