Re: Relationships and Relations

Hello Hans there quite a literature on n-ary relations, reification, etc.
What you call Relationships are usually called Frames or Knowledge
Patterns.

You may have a look at the Framester semantics [1] for a formal treatment
of frames across data, linguistic resources, and more, with a large
knowledge graph integrated under the hood of frames.
