Perhaps an example here like "the transportation of a work of art from
London to New York" would capture the 'relocation' concept with a more
relevant illustration than trying to call relocation of a person a
'derivation'? (which it clearly is in the model, I'm sure some
biography server will try to represent the provenance of a person
moving around like that someday -- it just bothers me)
