It forms the cornerstone of the W3C effort to create the Semantic Web, but its use isn’t restricted to this specific effort.
Perhaps because RDF is a description for a data model rather than a description of a specific data vocabulary, or perhaps because it has a foothold in English, logic, and even in human reasoning, RDF has a strong esoteric element to it that can be intimidating to a person wanting to know a little more about it. However, RDF is based on a well-defined set of rules and constraints that governs its format, validity, and use. Approaching RDF through the specifications is a way of grounding RDF, putting boundaries around the more theoretical concepts.
The chapter takes a look at two RDF specification documents that exist at opposite ends of the semantic spectrum: the RDF Concepts and Abstract Model and the RDF Semantics documents. In these documents we’re introduced to the concepts and underlying strategy that form the basis of the RDF/XML that we’ll focus on in the rest of the book.
