Özet:
In this paper, first, I describe semantic web and second, I elaborate on four blocks of semantic web
(XML, Resource Description Framework (RDF), RDF Schema, and Ontology) and finally some example of current semantic web tools and application. Semantic web is an extension of HTML (Hyper Text Mark up Language) and XML (Extensible Markup Language). XML and HTML play big part on semantic web implementation. The semantic web has been supported by W3C (www.w3c.org) organization, an international organization body for World Wide Web standardization
