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.
