- ### Items

  - #### createTimestamp

    Flags: RAM,runtime,oper

    Multiplicity: [0,1]

    The timestamp of data creation. It is set once and should never be changed.

    In case of "background" processes to create object (e.g. create with approval) this should be the timestamp when the process ended. I.e. the timestamp when the operation was executed.

  - #### creatorRef

    Flags: RAM,oper

    Multiplicity: [0,1]

    Reference to the user that created the data.

  - #### createChannel

    Flags: RAM,runtime,oper

    Multiplicity: [0,1]

    Channel in which the object was created.

  - #### createTaskRef

    Flags: RAM,oper

    Multiplicity: [0,1]

    Reference to the task that created the object (if it was a persistent one).

  - #### modifyTimestamp

    Flags: RAM,runtime,oper

    Multiplicity: [0,1]

    The timestamp of last data modification. It should be updated to a current time when the object is modified. The modifications that change only operational attributes may not update the modify timestamp.

  - #### modifierRef

    Flags: RAM,oper

    Multiplicity: [0,1]

    Reference to the user that modified the data.

  - #### modifyChannel

    Flags: RAM,runtime,oper

    Multiplicity: [0,1]

    Channel in which the object was last modified.

  - #### modifyTaskRef

    Flags: RAM,oper

    Multiplicity: [0,1]

    Reference to the task that last modified the object (if it was a persistent one). If the last modification was carried out by synchronous task, this reference will be empty.
