Hi Jonathan!
I'm glad you asked this question.
The answer is actually written in the fprm.scm code comments that the
relational mapping in Artanis is not going to provide database level
foreign keys. The solution is to provide higher-abstract-level table
operations as a replacement to save users to time to handle by

The pros and cons of foreign keys are discussed a lot in the
internet. The modern ORM may choose to drop foreign keys and provide
higher layer for it.

Unfortunately, this feature has not been implemented yet because of my time 

Of course, this issue is still open, the original plan is more
ambitious. I think it's the time to add more features to the relational
mapping framework.
Welcome to discuss if you like.

Best regards.
