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 organization is provided to explain how the protocol behaves. This specification does not mandate that implementations adhere to this model as long as their external behavior is consistent with that described in this specification.
The model suggested by this section includes the use of Active Directory as an external data store for user identity information. This is only one possible solution. Any implementation-specific internal or external data storage method can be used with the RMS Client-Server Protocol.
