Resource Description Framework
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. Add simple hidden annotations to your text, known as semantic tags, and your information (content) is more accurately categorized, found and ranked by search engines. RDF increases the value of your content in many ways, such as for search engine optimization (SEO).
Since semantic tags act like an index to your content that both computers and people can use to better understand it, RDF is used as a language for representing information about resources in the World Wide Web. The RDF metadata model makes statements about resources as subject-predicate-object expressions, "triples" in RDF terminology. A triple is very simple to understand. The content "The cat has the color orange" organized for expression in RDF would be:
- 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.
