Abstract

The purpose of this paper is to clarify the characteristics and the current stage of preservation metadata in comparison with descriptive metadata. Preservation metadata records information on preservation in all aspects. Descriptive metadata, cataloging records based on cataloging rules, is metadata which is expressed and used to find and identify a resource and distinguish it from others. Four preservation metadata element sets were examined which had been proposed in projects among libraries: National Library of Australia (NLA), CEDARS in academic libraries in UK, NEDLIB in European national libraries and OCLC/RLG working group. On the other hand, MARC21 Format for Bibliographic Data and Nippon Cataloging Rules, 1987 Edition, 2001 Revision were taken as representatives of descriptive metadata. In conclusion, preservation metadata covers not only a range of descriptive metadata but also more detailed systems requirements and information about material than those of descriptive metadata. Preservation metadata also includes administrative metadata, for instance reason for preservation and preservation history, which descriptive metadata does not make much of.
