Note

The flexibility of the RDF data model means that it’s being used more and more with projects that have nothing to do with the “semantic web” other than their use of technology that uses these standards—that’s why you’ll often see references to “semantic web technology.”

I like to define the semantic web as a set of standards and best practices for sharing data and the semantics of that data over the Web for use by applications. Let’s look at this definition one or two phrases at a time, and then we’ll look at these issues in more detail.
