content model object in Fedora: cmodel:pagedmulticopy
This content model will be used for collections where we expect to have multiple copies of objects for a single metadata record. It is somewhat similar to the FRBR-like model that the University of Virginia uses, but at a lower level. Where Virginia's model expresses work-to-item relationships, this model expresses manifestation-to-item relationships. That is, the objects being grouped together are very similar, and will all share the same descriptive metadata.
The multi-copy content model introduces a new level of object ("manifestation") into an existing content model. Each of these manifestation objects will have a metadata datastream that stores two things: descriptive metadata, and pointers to the objects that represent copies of this item.
Each of the item-level objects will follow a the same content model (but the specific model used is collection-dependent). The only difference between item-level objects that are part of a normal content model and objects that are part of the multi-copy model is that in the multi-copy model, descriptive metadata at the item level will be limited to the amount that would normally be placed in the Fedora default DC datasteam.
Even though a document with multiple copies is not the same as a paged document, it uses the same disseminator to access children of the manifestation object.

As usual, the page-level object holds image datastreams, and the item-level object holds a printable PDF.
