The IR holds a collection of alumni photographs. Sally is an alumnus who was invited to look at the collection, login and tag any of the other alumni she recognizes.

Professor Pete is browsing the collection of his department. He notices someone made a spelling error on a subject or another metadata field. This aggrevates him. As a member of the institution and able to login to the system, he expects that he's able to jump in and at least make a suggestion for a correction that is swiftly enforced/implemented.
