5) Topic Maps (using a binary association)

"There is a topic with the ID 'shoe-257' of type 'shoe',
and a topic with the ID 'red' of type 'colour',
and an association of type 'has-colour' in which
'shoe-257' plays the role 'object' and
'red' plays the role 'colour'.

6) Topic Maps (using a unary association) [1]

"There is a topic with the ID 'shoe-257' of type 'shoe',
and an association of type 'is-red' in which
'shoe-257' plays the role 'object'.
