Re: RDF-star use cases from Amazon Neptune

Yes, nice and concrete!

What if Alice were Elizabeth Taylor, and Bob were Richard Burton

Wikidata's data model records their two marriages as edge annotations, on
the
https://m.wikidata.org/wiki/Property:P26 relationship linking them.

Eg. https://m.wikidata.org/wiki/Q34851
https://m.wikidata.org/wiki/Q151973

From a Schema.org point of view, being able to express more of what
Wikidata can do seems attractive for interop.
