Resource Description Framework
The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. This Primer is designed to provide the reader with the basic knowledge required to effectively use RDF. It introduces the basic concepts of RDF and describes its XML syntax. It describes how to define RDF vocabularies using the RDF Vocabulary Description Language, and gives an overview of some deployed RDF applications. It also describes the content and purpose of other RDF specification documents.
Example: "The cat has the color orange" organized for expression in RDF:
- Subject = "the cat"
- Predicate = "has the color"
- Object = "orange"
The subject is the resource, and the predicate (denoting traits or aspects of the subject) expresses a relationship between the subject and the object. The RDF metadata model makes statements about resources as subject-predicate-object expressions, "triples" in RDF terminology.
