Hi Franck Thanks for the background. As I am not an expert on IFC, I can do an overview presentation which will hopefully help the rest of the team get an overview of what it offers and how it differs from CityGML. I believe the integration of all levels of detail will eventually need to be seamless and therefore adopting enough standards to cover all domains would be important. Let me know if I should prepare, I will gladly do so.
