RDF
RDF está basado en la idea de identificar los recursos en la We busando los Uniform Resource Identifiers o URIs, y describie ndo losrecursos en términos de propiedades simples y valores. Unadescripción RDF es un conjunto de proposiciones simples (ta mbiénllamadas sentencias o declaraciones) y una proposición se c onocetambién como una tripleta, porque está compuesta de 3 cosas: unsujeto, un predicado y un objeto. Estas sentencias se puedenrepresentar formalmente usando la tripleta (sujeto, predi cado,objeto), pero existe otra forma de notación que es mostrar un asentencia mediante grafos dirigidos. Así, en RDF es posiblerepresentar declaraciones simples sobre los recursos como un grafo(graph) de nodos y arcos que representan los recursos, y suspropiedades y valores.
RDF (Resource Description Framework )
Los 3 elementos de una tripleta se representan medi ante 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 bla nco� Predicate puede ser una referencia URI� Object puede ser una referencia URI, literal o un n odo en blanco.
