Enhanced Semantic Web Layered Architecture Model

This paper introduces the traditional web and its limitations, and how these limitations can be overcome by putting the lights on a new interesting approach for the web which is the Semantic Web. The most common technologies that can be used to construct such smart web are discussed briefly, and then its current layered architecture models as proposed by Tim Berners-Lee and others are evaluated to alleviate discrepancies and weak points. An enhanced architecture obeying layered architecture evaluation criteria and standard principles is proposed. This enhanced model is evaluated and contrasted against other models. Key-Words: Semantic web, ontology, XML, RDF, URI and Functional Layers.
