The breakdown, or division, you see in the OCLC/Schema document actually
reflects our thinking initially, and by "initially" I mean in that
period after the introduction of the model/vocabulary but before we'd
done some real experimentation and testing. Rob's synopsis captures the
division as we see it today. (And you hit on a small issue, which is
that old documentation is not as revisited as one would like in order to
update to reflect changes.)

All the best,
Kevin

The manifestation resource is linked to the work resource, but here the task would be to link some fragment of the manifestation description with a specific triple of the work description (the text fragment plus some information found elsewhere plus the intellectual activity of the cataloguer culminated in that specific triple - why shouldn't that be documented within the data we create?).

Coming from data expressed in one model (say, FRBR) which _does_ possess a richer ontology, how do we re-express relationships in Bibframe that begin as relationships from either works or instances to intermediating classes (or for that matter, between intermediating classes)?
