| FRBR: The physical embodiment of an expression of a work. ++Philosurfical: Since a manifestation can also be the single item (manuscript) produced by an author, a publication is something different from a manifestation.In such an extreme case, the instance of manifestation represents the one-element set comprising the only existing copy of the expression - and the instance of the item class stands for the physical object itself. The has-title slot is inherited, and the was-made-by too |
