Re: RDF-star use cases from Amazon Neptune

Thanks Pierre-Antoine and I was trying to parse
https://pr-preview.s3.amazonaws.com/w3c/rdf-star/pull/225.html#married-example
but got an error and was looking like crazy for the error in EYE, but it
was in the example itself:
the comma after 1975 should be a semicolon like

:lizTaylor :married :richardBurton {| :occurrence
    [ :year 1964; :location :montreal ],
    [ :year 1975; :location :botswana ]
|}.

which now gives

:lizTaylor :married :richardBurton.
<<:lizTaylor :married :richardBurton>> :occurrence _:bn_1.
<<:lizTaylor :married :richardBurton>> :occurrence _:bn_2.
_:bn_1 :year 1964 .
_:bn_2 :year 1975 .
_:bn_1 :location :montreal.
_:bn_2 :location :botswana.
