The Semantic Web is about two things. It is about common formats for
integration and combination of data drawn from diverse sources, where on the original Web mainly concentrated on the interchange of
documents. It is also about language for recording how the data relates to
real world objects. That allows 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.
