3.1.1 Abstract Data Model
This section describes a conceptual model of possible data organization that an implementation maintains to participate in this protocol. The described organization is provided to facilitate the explanation of how the protocol behaves. This document does not mandate that implementations adhere to this model as long as their external behavior is consistent with that specified in this document.
The Delegate Access Management Web Service Protocol is used to set, retrieve, update, and delete delegate access permissions on a primary account's mailbox on the server. The server maintains the delegate access permissions and modifies them as requested.
The client is not required to maintain the state of delegate access permissions on the server and can retrieve the current set of permissions at any time. If more than one client is changing delegate access permissions, there is no requirement that the server lock the existing set of permissions for changes.
