Hello guys, how would you define a follower relationship in the schema? I was thinking of:

definition user {
    relation follower: user
}

definition document {
    relation reader: user | user#follower
...
    permission view = reader + owner
}

document:follower_content#owner@user:adrian
user:daniel#follower@user:adrian
document:follower_content#reader@user:adrian#follower

But I don't think that works.
