The item obj_persid will show either the contact uuid or role id, based on what the scoreboard query was created for.
The item role_persid will show the role related to the contact or role the scoreboard query was created for.
For example, if you create a query for a specific contact, it'll show their uuid as obj_persid, and their role as role_persid.
