Useful, but not perfect. Not great for beginners. Thorough without feeling complete.

Chapters 14 and 15 on Modeling processes and best practices are the most useful bits -- this is what I was looking for when I bought the book!

I love Semantics, RDF, RDFS, OWL, SKOS, and use them at work, but finishing this book was a real chore. The text is fine, but could be 1/3 the size with some prose refactoring. I think more graphs and better graphs would have helped as well.
