We present an experiment of customized mapping and metadata transfer from DSpace/SOAR to OCLC to improve ETD work flow at Wichita State University Libraries. SOAR (Shocker Open Access Repository) is a DSpace based digital library platform to preserve intellectual output of university faculty and researchers. It includes the University theses and dissertations that are cataloged in SOAR and OCLC. Until early 2008, catalogers have been creating two records (Dublin Core and MARC) for the same title manually. The goal of the experiment is to automate the process of generating MARC records from Dublin Core metadata in SOAR and importing them to OCLC and Voyager. This presentation will discuss how we harvest theses data from SOAR using MarcEdit developed by Terry Reese at Oregan State University Libraries, how we customize Library of Congress’s XSLT mapping to transfer Dublin Core metadata to MarcXML metadata and how we export MARC data to OCLC. The customization includes selective data transformation, metadata element positioning, field relationship definition, field indicator correction and validation and partial data extraction. This customized mapping and data transformation can eliminate the need of double entry in SOAR and OCLC, meet our local needs and significantly improve our ETD work flow.
