Individuals may be real, legendary or imaginary, and do not need to be biologically unique. Personas adopted for artistic
or other purposes may be referenced with DOIs as unique individuals. For example, the authors 'Ellis Peters' 'John Redfern'
'Jolyon Carr' and 'Peter Benedict' may be identified as a unique parties distinct from the person 'Edith Pargeter', for whom
they are all pen-name pseudonyms. 'Mickey Mouse' may be identified as an individual for the purpose of unique identification
as a performer in a creation, or 'Borat' or 'Hamlet' for the identification of a character depicted in a fictional work.
