Does UAM fit this use case?

When a new member registers, the site will create a single post or page and assign them as the author/owner. So every user has a single page.

Members establish relationships. Think of Facebook-style “friends”, where you can only see a private profile (the above post/page) if you have a relationship.

In this case, there are different types of friends. Groups in UAM? :

– Member2 can be in a Friend group with Member1. Everyone in the Member1 Friend group sees the same content on Member1’s page.
– Member3 can be in a Family group with Member1, and does not see data intended for Member1 Friends. (I believe this is accomplished with a UAM shortcode?)
– Member3 has no relationship with Member2, there is no “friends of friends” relationship.

The relationship types might be hard-coded initially or set in configuration, but it would be best if I could code a scenario where members can create their own type. So by default there would be a Member1_Friend type and a Member1_Family type, but they might add Member1_CoWorker, and then assign that type to other members/friends.

I’d like to know how close UAM already fits this scenario, and what I might need to code myself to achieve the rest.

Thanks!
