I had to do some diagrams to explain what I see as the possible 
relations between BIBFRAME "authorities" and "library authorities, and 
since email doesn't work well for that I did a blog post instead:

I apologize if this splits the conversation, and can echo back here any 
significant comments.

The main gist is exploring options for the positioning of the BIBFRAME 
authority thing in relation to the traditional library authority "record."

It needs some example code, but I'm struggling with that because code 
isn't very readable, and the more readable types tend to mask the 
triple-ness of the underlying data.

Owen Stephens has given me an idea for a fourth diagram, which I will 
add if I get a chance.
