Looks like a very good book. It is probably among the very few books which talks about the use of RDF/DAML in semantic web. With information about FIPA, topic maps in there I think the book contains info. about how the technologies for semantic web have evolved.
I had one question though:
Now that RDF/DAML/OWL (is it in there?) becoming standard for the modeling, the new widespread problem people are facing is versioning and comparison of the knowledge represented on the semantic web. There are many papers on versioning in ontologies but not much on how it can be generalized to semanticweb. Does your book touch on this aspect?
