     Description:

        This document is a Topic Map in Linear Topic Map (LTM) notation,
        representing the FRBR hierarchy as described in
          "Hierarchical Catalog Records", David Mimno, 
          Gregory Crane and Alison Jones. D-Lib Magazine, October 2005,
          Volume 11 Number 10, ISSN 1082-9873.

        This creates a hierarchy for describing published works,
        expressions of those works, manifestations of those expressions,
        and finally, specific items or instances of those manifestations.
