The OLAC task group appears to be hewing closer to FRBR-∞ rather than
Entity/Relation
definitions in the IFLA FRBR report. The strict FRBR-ER model is not really
usable, as the boundaries between entity classes are not rigorously drawn,
and the model makes some ontological commitments that may not be desirable
(for example, if Manifestations are physical, Items must be detached
manifestation parts, or manifestation must be a substance). It's best to
treat the IFLA report as an inspiring metaphor, rather than as literal
truth...
The approach that OLAC is following seems to be inspired by Martha Yee's
model of "Near Equivalents"; e.g. Yee (1994). Near equivalency very roughly
corresponds to two items being close enough to one another to be satisfy a
particular need. Confusingly, Yee's use of *Manifestation* predates the
FRBR report, and more closely corresponds to FRBR Expressions than to FRBR
Manifestations. Yee's and Tillet's approaches *are* based on the same
Principles (Svenonnites? Lubetskavitchers?). [Checking the link that Matthew
posted, I see that Yee was an advisor to the OLAC task force].
Near-Equivalents might be thought of in terms of relative identity, with
fewer properties being held in common between as one moves from items to
works. A manifestation could be considered to be an abstraction of items
that ignores properties related to the specific physical particular (such as
being made of the same atoms, or being at a specific place at a particular
time). Relative Identity does allow for a consistent interpretation of
I/M/E/W but is thought by some to be too far from FRBR to be applicable,in
addition to having foundational objections to non-absolute identity (Allen
Renear and Karen Wickett at UIUC have strong views on that score).... It's
also possible that Near Equivalency could be relative to a specific patron
and task. It's not inconceivable that individual properties could be used
to aggregate results or narrow result sets,
