Could you please provide an example for relationship responses in the examples section of the website, as this is really confusing for newbies of the spec. I did not grasp the difference in the response of xxx/relationship/yyy and xxx/yyy from the spec alone.

There is a great example here:

https://discuss.jsonapi.org/t/self-vs-related-links-and-what-to-return/1236/13

Maybe it is possible to copy that example, it was of great help for me.

Thanks for the spec 😁
