Enable semantic descriptions of the applied geometry representation contexts

[FransKnibbe]

Contributed by Anna Wagner and Mathias Bonduel for the white paper "Benefits of Representing Spatial Data using Semantic and Graph Technologies":

Some geometry schemes can contain a variety of geometry representation contexts (BREP, CSG, NURBS, etc.) but not all applications can deal with every geometry representation context. To ease the integration of geometry descriptions into applications, metadata regarding the geometry representation context at hand could help to automatically retrieve suitable descriptions only. Example: DWG can contain a 2D drawing, a 3D mesh and/or 3D BREP geometry.
