Instead of defining a specific model-driven approach and UML profile for the IFC UML model, the IFC model can be described within the existing approach defined by ISO/TC 211 for the GIS application domain. The ISO/TC 211 approach is based on general MDA and UML concepts and adapted for modelling of geospatial information. This would improve the possibilities for closer integration with the GIS application domain and enable implementation of IFC in technologies for both BIM and GIS.
We have discussed the issue of implementation of IFC as ISO/TC 211 compliant UML models in a newly published article: https://www.mdpi.com/2220-9964/9/4/278.
