Issues in Metadata Crosswalks: A Case Study of Qualified Dublin Core and Onix

In the traditional library environment Cataloging in Publication (CIP) is very popular and the library staff can make use of CIP records to generate minimal cataloguing information. With the advent of Internet and the presence of book industry on the Net, the growing importance of metadata has resulted in ONIX (ONline Information eXchange). The benefits of crosswalk between ONIX and Dublin Core are too obvious to be ignored, as it saves the time of cataloguers in generating metadata in Dublin Core for the e-books or even printed books acquired by a library. This paper attempts to investigate the possibility of generating required metadata from available metadata formats, particularly the most popular Dublin Core (DC) from ONIX and presents mapping between ONIX and Qualified Dublin Core.
