Something needs to be said that structural bnode-isomorphism and the
meaning of the dataset are now separate issues, unlike graphs.
# Dataset D1 - links to bnode graph
{ :s1 :observed _:a }
_:a {:s2 :p2 456 }
_:b {:s2 :p2 123 }
# Dataset D2 - same meaning as D1, no such link
{ :s1 :observed _:z }
_:a {:s2 :p2 456 }
_:b {:s2 :p2 123 }
# Dataset D3
{ :s1 :p _:z }
<g> {:s2 :p _:z }
# Dataset D4 - same meaning as D3, bnode not now shared
{ :s1 :p _:a }
<g> {:s2 :p _:z }
