Re: Historical events

Hello

I believe there has been some work on WikiData around ships 
<https://www.wikidata.org/wiki/Wikidata:WikiProject_Ships> [1] that 
might help,  I'm no expert, but have a friend who is a naval historian 
and so I have looked at that work a little.

shipwrecking <https://www.wikidata.org/wiki/Q906512> [2] might be a 
better term than sinking: not everything that gets wrecked sinks.

In wikidata, a shipwrecking is an event, and ships have a property 
significant event that can be used to link the ship to its shipwrecking.

In schema.org Event has a property subevent, so you could say that the 
sinking of the Lancastria was a subEvent of WW2.
