SEO Semantic Web
An extension of the current Web that provides an easier way to find, share, reuse and combine information more easily. It is based on machine-readable information and builds on XML technology's capability to define customized tagging schemes and RDF's (Resource Description Framework) flexible approach to representing data. The Semantic Web provides common formats for interchange of data (where on the Web there is only had interchange of documents). It also provides a common language for recording how the 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.
