RDFS:An Extension To RDF

The data format to represent the Meta data of web resources is defined as the Resource Description Framework (RDF). RDF deficits in defining classes and their respective properties. While, RDF Schema (RDFS) is the mechanism of defining application-specific classes and their properties. Still, RDFS is just providing a framework to describe the classes and their properties. RDFS allows relating the classes as superclasssubclass. RDFS which incorporates class hierarchy can help in enriching the RDF. This paper discusses the limitations of the RDF and the basics of the RDFS using examples
