Imagine an XML Schema that defines the "hard" metadata for a book, e.g. author, title, ISBN. These are immutable properties of the book. Now, the New York Times does a review of the book which creates "assertions" which are not hard facts but still related information. The connection of these assertions to the book would be through RDF. RDF might also be used by various booksellers to make assertions about the price they are individually charging or possibly special offers about the book. I have not yet tried to create concrete examples to see how well I can make this work, but for now, it is the framework through which I'm trying to make sense of the ambiguity. I'm open to other interpretations.
