Will FRBR turn out to be a failure like DC (Dublin Core)?
Jeffrey Beall (2006) asked an interesting question "Will FRBR turn out to be a failure like DC?"
Obviously DC failed in some way; but I believe that it was and is the basis for many metadata schemas. FRBR will have the same or more effect on bibliographic information systems, even if it fails.
