The Spatial representation of building composition elements

This schema contains the concrete classes that are used to model the spatial structure of a building.That spatial structure is often used to provide a project structure to organize a building project.

Due to the importance of IFC in coordinating spatial structure, the classes in the schema are intended to have a 1:1 instance mapping (not class mapping!) with IFC that will work for transformations in either direction. It is expected that round-trip transformations may result in changes that provide an equivalent, but not identical model.
