Except that there is no guarantee you can get anything useful from the
namespace URI (sadly, IMHO) - all the spec provides is that this is supposed
to be a way to uniquely identify the thing referred to. And that requires you
make up a namespace that won't get used by someone else, which is not
necessarily possible to guarantee either :-(

  this is not an #include ; this is only a shortcut, so you don't have to type the whole URI of other schemas each time.
  If your RDF parser want more details about the properties you use, it will retrieve corresponding schemas ;
  whether it will store the whole schema or only triples related to the properties you use is an implementation choice,
  you can't mkae hypothesis on it.
