This file documents the structure of the roster object.

table roster {

  [string bare_jid] = roster_item

}

table roster_item {

  string subscription = "none" | "to" | "from" | "both"

  string name = Opaque string set by client. (optional)

  set groups = a set of opaque strings set by the client

  boolean ask = nil | "subscribe" - a value of true indicates subscription is pending

}

The roster is available as

 hosts[host].sessions[username].roster

and a copy is made to session.roster for all sessions.

All modifications to a roster should be done through the rostermanager.
