I'd rather say his proposal (objects->facts->links->...) is complementary to the current SW layer cake. It shows what is going on conceptually, whereas the current SW cake (which I agree probably needs to be fixed) is more of a technology stack. An interesting paper I read related to this is: A. Gerber, A. van der Merwe, and A. Barnard. A functional Semantic Web architecture. In Proceedings of the 5th European Semantic Web Conference (ESWC2008), Tenerife, Spain, pages 273–287.

Not that I don't think they are extremely important, but what I see in Ravinder's stack is a description of the nature of data on the SW. Of course, what I see might not be what he intended! :) The next layer should describe how the data is different from the previous layers. As I pointed out in a previous mail, I think this difference could be in inferenced data vs. explicit data.
