Rdf & Rdf Query Languages – Building Blocks For The Semantic Web

Although the World Wide Web is a relatively new concept, its expansion and the impact it had on the population were great. The Web is characterized by a network of interlinked documents, most of them designed to be read by humans, not interpreted by machines. The Semantic Web comes as a complement to the current web in which the available information can be interpreted by machines also, not only by people. Web services provide methods of publishing services in an UDDI registry, description of interfaces using WSDL and messaging through the network using various protocols, the most common being SOAP. This paper examines the close link between The Semantic Web and Web services, as well as other technologies necessary for this interaction.
