The current bibliographic structure is essentially bifurcated between: bibliographic records that describe and support access to resources; and, authority records that authorize and structure the headings/access points employed within the bibliographic records.  The paucity of information recorded and functionality of our authority records betrays their roots as a subordinate structure to support the main (card) catalog.

The Functional Requirements family of models articulate a structure where all of the associated entities in a bibliographic universe exist on a relatively level and agnostic playing field -- the records for works, expressions, manifestations, items, people, families, corporate bodies, concepts, objects, places, events are all of equal importance to the functioning of the overall database.   Recorded elements are distinctly and uniquely associated with each class of entity.  In particular, records for entities formerly addressed by authority records are significantly more robust, holding elements above and beyond the mere heading/access point.  Elements from related entities across the database are gathered and presented to form the display we traditionally associate with a bibliographic record.

The BIBFRAME model, in its overview articulation on p. 8 of the report, appears to sustain the former model, with its references to Instances and Authorities.  The further details and then the articulation in "Serializing the BIBFRAME model" however, show that things are somewhat better aligned with the FR family than the overview indicates.  

There are still some concerns though that:
* the distinct nature of the elements associated with the FRBR Work and Expression entities will be muddled in the BIBFRAME Creative Work class;
* the FRBR Item entity will be inadequately articulated or will be subordinated within the BIBFRAME Annotation class;
* a subtle intellectual bias dividing the catalog into the BIBFRAME Instance class and "the rest" will persist.

Having said that, I think the report is an interesting starting point for further conversation  The devil will be in the details, as they say.  So working out implementation will be a critical aspect, that will trump all the labels we apply.

Dear Bob,

Thanks for the early feedback.  I look forward to your thoughts once you've read the document more thoroughly.  

I wanted to take the opportunity to comment on or request further information about this:

I think it possible that Authorities (People, Places, Topics, Organizations) and Instances (as well as Works) could be seen as equal entry points and therefore not "continue the division of the database," but I may be misunderstanding you.  

Even as I write/read that statement, I feel like I am not understanding your point.  

Can you tell us *how* the proposed model continues the old model with respect to the "division of the database"?
