Working with data on relationships


That is intentional. You either have a resource to contain the relationship data, or a very, very limited data flavoring of the relationship. Pragmatically speaking, I understand the reason for the limited data on the relationship, but simply including this option is a slippery slope, as demonstrated by the frequency this topic comes up.

If you need more than a very simple augmentation, the problem isn’t in the spec but in the design of your resources themselves.
