Dempsey on models
Lorcan Dempsey (of OCLC) posted Metadata … on his blog last week. He discusses “conceptual models” like FRBR (What is FRBR? asks Barbara Tillet’s introductory booklet, and the subtitle answers “a conceptual model for the bibliographic universe”), “abstract models” like Dublin Core, and other things. It’s worth a read; also check the comments and follow some of the links.
