Semantic Web is an extension of the current Web that provides an easier way to find, share, reuse and combine information. It is based on machine-readable information and builds on XML technology’s capability to define customized tagging schemes and Resource Description Framework (RDF) flexible approach to representing data. It provides common formats for the interchange of data. It also provides a common language for recording how data relates to real world objects, allowing a person or a machine to start off in one database, and then move through an unending set of databases which are connected not by wires but by being about the same thing.
