Coyle, Bibliographic ER
Karen Coyle’s blog post Bibliographic E-R from last Sunday is about entity-relationship models. FRBR is set up as an entity-relationship model (though FRBRoo recasts it in an object-oriented model). Coyle notes:
This type of model is expressed in FRBR, but the E-R aspect of FRBR does not seem to be incorporated into RDA as it stands today. Instead, RDA appears to be aimed at creating the same flat structure that we have in library data today.
