Semantic Web is an extension of current web that provide machine readable format to allow machine (computer) to process, analyze and understand the meaning of data. There are some supported components to realize the concept of semantic web, also known as Semantic Cake. Figure below depict the picture of Semantic Cake. The widely used format in semantic web is rdf and ontology. RDF is a XML format document that represent data or information in directed-labeled graph in the Web. It does that by structuring information in subject-predicate-object called statement. The subject of 1 statement can also be the object of another statement creating rich-interrelated knowledge based. RDF is needed in the concept of Semantic Web, because it conveys the meaning that can be understood by computer.
