Semantic Web: XML and RDF Roles

AbSTRACT This research paper presents an overview of the main concepts of the semantic web, and is aiming to present some ideas of developing the concept of semantic web using XML and RDF. In particular, the research reveals the positive impact of using RDF instead of XML through the concept of “Semantic Web”, with the knowledge that many of the researches demonstrated the preference of RDF for the many reasons including simplicity, abstract syntax, and providing a data model. In particular, our main goal is to define the appropriate elements to develop a semantic web using both XML and RDF. Our approach is achieved by developing a simulated web search engine to describe and emphasize the positive role of using RDF rather than XML in web search. key words: XML, RDF, W3C
