Two steps of the semantic traceability operation of the proposed tSDT approach

Caption

The semantic traceability feature is designed to track the changes of IFC-GUIDs during the tSDT processing. The semantic traceability consists of two separate steps. The first step creates a one-to-one mapping dictionary (D(1)) between IFC-GUIDs and IFCJSON-UUIDs, while it also converts the IFC file into an IFCJSON format. Then, during the streamlining of the semantic hierarchy of IFCJSON objects, the semantic traceability operation records the one-to-multiple mapping (D(2)) between IFCJSON-UUIDs and tSDT-UIDs. This mapping relationship between original IFC objects and semantic hierarchy objects enables semantic traceability. Furthermore, the one-to-multiple mapping dictionary between IFCJSON-UUIDs and tSDT-UIDs allows for the elimination of redundant semantics.
