@jwouellette It seems that these days many have focused on IFD  
Which including texture and also “material development” becomes important for “PDT”

This is why these days we hear this question constantly

And I think if buildingSMART wants IFD and IFC be integrated and work well with each other have to “reconstruct” IFC structure, and focus more on “Classification” and “Material Catalog/Dictionary” development
