Why shouldn't it be possible to express incomplete assertions in topic maps? For example: (1) "A and B are related, but I don't know how" (no association type or role types; role players known) (2) "A is married, but I don't know who his wife is" (association types and role types known; one role player unknown) (3) "A and B are married, but I don't know who wears the trousers" (association type and role players known; role types unknown) Another example of (3), from the Italian Opera topic map: "Puccini was the teacher of Ponchielli... Is was it Ponchielli that taught Puccini? Damned if I can remember!" Why should the RM, the SAM or the syntax prevent us from expressing these kinds of incomplete knowledge?
