dear all:
quite clearly, a book title is not the same as a book, and if the linked 
data community continues to link apples and oranges via owl:sameAs then 
either

- the socially agreed meaning owl:sameAs is being degraded to untyped 
href in HTML
or
-  vast amount of data in the linked data cloud turns useless

but as a minimum precaution against spoiling the graph of data, put your 
sameAs statements into separate graphs so that meaningful applications 
can filter them out easily.
