"The concept of chapters of a Work being different Works from their parent Work when and only when carried by a particular carrier worries / confuses me deeply; I'll certainly follow your experiments with interest."

+1

Another way of looking at chapters is to look at them as Instances of the primary Work (and not separate Works in their own right).

Thanks,

They are less unsatisfying than I had feared, which gives me hope. Thank you for your concrete answers to concrete questions.

Would it be possible to have at least a link from http://bibframe.org/vocab/Instance to the definitive definition of Instance in the model? I believe that this is what humans are going to expect and be looking for when they go to http://bibframe.org/vocab/Instance

This page - http://archive.ifla.org/VII/s13/frbr/frbr_current_toc.htm - which is basically the landing page for the *entire* report would be an Instance of that Work.  However, the page you direct to in your question is not the same as the link I provided.  Your link is to a distinct chapter of that Work.  One option for the model would be to create a BIBFRAME Work resource for the chapter, which, being a BIBFRAME Work, would have an Instance (represented by your link).  There would be a defined relationship between the BIBFRAME Work for the entire report to the BIBFRAME Work for Chapter 3.  We've been experimenting with this idea.

The concept of chapters of a Work being different Works from their parent Work when and only when carried by a particular carrier worries / confuses me deeply; I'll certainly follow your experiments with interest.

Cataloguing, as the human activity we know, is unlikely to be widespread at this granular a level. That doesn't preclude libraries using the BIBFRAME model at this level.

For example, I maintain http://nzetc.victoria.ac.nz/ which contains full text works as HTML (also in parallel with PDF, page images and ePub). 
Every file / URL on that website is part of a CIDOC model (with the exception of some branding-related content). All the navigation links are derived from the model. All licensing links are derived from the model. Decisions about which files to bundle into ePub are derived from the model. Faceted search and parallel-language search is based on the model (full-text aspects of the search not so much). Authority control (for people, works, places and ships) is based on the model. Everything is based on the model.

The NZETC is a collection of an academic library and the decision has come from on high that the NZETC is to take concrete steps to move closer to, and be more integrated with, other library collections. This will be orders of magnitude easier if BIBFRAME can be used, since it makes deep interoperability with core library systems a realistic possibility.

I am happy to generate illustrated use-cases based on our work if that would be helpful.

It is too early to tell whether it has such a narrow use in the future, but it is meant to capture the notion that "This Work is the product of a merger of these two other Works."  I believe what you are trying to do is something completely different.  And, FWIW, the attempt to sensibly record how all the parts of an HTML document logically fit together is not something we're focused on.

Could a note of this fact (maybe with a link to the definition) please be added to http://bibframe.org/vocab/unionOf ?
