It is not possible to create a dictionary item which names the association. A workaround would be to
Create an attribute (dropdown-box) for the data object category in the dictionary to maintain these different states like create, change, etc.
Create a dictionary category Document States including these different states as entries
Link them to data objects in a dictionary link attribute (as list)
Create a attribute for the association with the desired states.
With all three options the value is not show on the diagram but in the attribute list.
