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.
