3.1.1 Abstract Data Model

This section describes a conceptual model of a possible data organization that an implementation could maintain in order to participate in this protocol. This organization is provided to facilitate the explanation of 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 document. The following data items are implemented on the server side and are specific to this protocol:

• PDCRoleHolder: For servers of domain-based DFS namespaces, this is the PDC corresponding to the server's domain.

• DFSMetadataCache: DFS metadata of DFS namespaces for which the server is a root target MAY<26> be cached as an optimization.

Note The preceding conceptual data can be implemented using a variety of techniques. There are no limitations on data implementation.
