It seems that TKS will go into Practical RDF. iTQL isn't mentioned but given the time constraints it's pretty good anyway. There's even a chapter with XUL and RDF in Mozilla.
It looks like it will be a good book. However there were a couple of things that I thought were missing:
* P2P and RDF - like Edutella.
* Annotation - like Annotea.
* Document management - like DSpace.
* IRIs - Can't really tell though from just the TOC.
