maybe the "not" is the problem here...
the good news is that
[[
  Just as the design of the Web sacrificed link integrity for
  scalability, the "all knowledge about my thing is contained
  here" notion cannot hold when databases and objects are
  exported to the Web. A great benefit to relaxing this
  assumption will be that, just as hypertext links connect
  different information systems, the Semantic Web will connect
  data from vastly different systems, allowing complex and
  far-reaching processing of a wide store of available data.
