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.
