The Semantic Web, that adds a conceptual layer of machine-understand­ able metadata to the existing content, will make the content available for processing by intelligent software allowing automatic resource integration and providing interoperability between heterogeneous systems. The Semantic Web is now the most important influence on the development of the Web. Next generation of intelligent applications will be capable to make use of such metadata to perform resource discovery and integration based on its seman­ tics. Semantic Web, aims at developing a global environment on top of Web with interoperable heterogeneous applications, agents, web services, data repositories, humans, and so on. On the technology side, Web-oriented lan­ guages and technologies are being developed (e.g. RDF, OWL, OWL-S, WSMO, etc.), and the success of the Semantic Web will depend on a wide­ spread industrial adoption of these technologies. Trend within worldwide activities related to Semantic Web definitely shows that the technology has emerging growth of interest both academic and industry during a relatively small time interval.
