Hi!

I want to create the two Entity Types Country and Town.
Every Town belongs to a Country.
I want to use the mymodule.schema.yml file to describe the schema, however I dont know how to put the relationship in this file.
Can anyone provide a sample for my specific example?

Town and Country both would have an ID and a Name. The Town would belong to a Country.
Do I have to additionally add something to the Town-/Country-Entity-Files?
