RDFRDF (Resource Description Framework)RDF está basado en la idea de identificar los recursos en la Web usando los Uniform Resource Identifiers o URIs, y describiendo los recursos en términos de propiedades simples y valores. Una descripción RDF es un conjunto de proposiciones simples (también llamadas sentencias o declaraciones) y una proposición se conoce también como una tripleta, porque está compuesta de 3 cosas: un sujeto, un predicado y un objeto. Estas sentencias se pueden representar formalmente usando la tripleta (sujeto, predicado, objeto), pero existe otra forma de notación que es mostrar una sentencia mediante grafos dirigidos. Así, en RDF es posible representar declaraciones simples sobre los recursos como un grafo (graph) de nodos y arcos que representan los recursos, y sus propiedades y valores.07/20092Diego Herrera

RDFElementos de una tripletaLos 3 elementos de una tripleta se representan mediante URIs.Donde:Subject y Object son llamados nodos

Predicate y Property son sinónimos

Nodos sin nombre son nodos en blanco

Subject puede ser una referencia URI o nodos en blanco

Predicate puede ser una referencia URI

Object puede ser una referencia URI, literal o un nodo en blanco.07/20093Diego Herrera
