All, 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: http://kcoyle.blogspot.com/2013/05/bibframe-authorities.html 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. kc -- Karen Coyle [log in to unmask] http://kcoyle.net ph: 1-510-540-7596 m: 1-510-435-8234 skype: kcoylenet
