A Resource Description Framework (RDF) is a method that can be used to more accurately label information so people and search engines can find it. By adding simple hidden annotations to text, known as semantic tags, information is more accurately categorized, found and ranked by search engines.
RDF is a language for representing information about resources in the World Wide Web. 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.
RDF's increase the value of your information in many ways, such as for search engine optimization (SEO).
The Primer linked to at the bottom of this page 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.
