Last month I posted a link to a paper by Allen H. Renear and Yunseon Choi: Modeling Our Understanding, Understanding Our Models: The Case of Inheritance in FRBR (95 KB PDF). There are a couple of comments on that post, and yesterday Karen Coyle posted FRBR OO – Not? on her blog, and Jonathan Rochkind left a comment. Have a look. I read the paper over the holidays but need to read it again before following up.
