Either would do - just a means of filtering by the target of a change. 
Could be split into another table i.e. object_type_id and a table for 
object types.

I guess we might also want to distinguish attribute changes from membership 
changes. I’m thinking of systems which might want to pull information - but 
have specific needs which, if reflected in the tables, can reduce the 
amount of data that needs to be retrieved and processed. We might want to 
have a tool which can recreate, for a specific group, its membership at 
specific points in time.
