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 specification does not mandate that implementations adhere to this model as long as their external behavior is consistent with that described in this document.

A Message object is always considered to be in one of the following states with respect to this protocol:

  • Unflagged

  • Basic-flagged

  • Color-flagged

  • Time-flagged

  • Flagged as complete

  • Recipient-flagged

  • Sender-flagged

Otherwise, the abstract data model of the Informational Flagging Protocol does not differ significantly from the abstract data model of the Message object to which this protocol is being applied. For details about the abstract data model of the Message object for the client, see [MS-OXCMSG] section 3.1.1.
