I should mention that I am keeping a wiki page [1] relating to the various versions of FRBR in RDF, with links to discussions around the issues of modeling -- in particular the question of defining the FRBR classes as disjoint. Also, FRAD [2] resembles FRBR in structure, but FRSAD [3] takes a very different approach with only two classes, Thema and Nomen. An interesting aspect of FRAD, which reflects standard library practice, is that it retains the concept of a "controlled access point" and includes a relationship to the rules under which the access point was developed and the agency that created the access point by applying the rules. If I run into discussions of these latter FRs I will add them to the wiki page. kc [1] http://futurelib.pbworks.com/w/page/48221836/FRBR%20Models%20Discussion (and linked from the home page http://futurelib.pbworks.com ) [2] http://www.ifla.org/publications/functional-requirements-for-authority-data (This is the web page for the committee. The English language version of FRAD is not available online, but there are other languages available on that page.)
