The web has grown steadily since its inception in 1990. Websites developed today are now tagged as Web 2.0; that is, they are user oriented and allow distributed publishing. Web 2.0 still follows the principle of the early web, a system of interlinked documents without organization. To onus was on the developers to design web applications that allow user interaction. The semantic web is the next generation of the web; its aim is to make the web a system where all data are interconnected thus bringing organization to the web. This paper reviews the technologies of the current web, semantic web and its application areas.
Key words: Semantic web, OWL, RDF, sparql, web 3.0, ontology, www, web 2.0.
