- Abstract
- The MARC standard for representing catalogue records and the Z39.50 standard for locating and retrieving them have facilitated interoperability in the library domain for more than a decade. With the increasing ubiquity of XML, these standards are being superseded by MARCXML and MarcXchange for record representation and SRW/U for searching and retrieval. Service providers moving from the older standards to the newer generally need to support both old and new forms during the transition period. YAZ Proxy uses a novel approach to provide SRW/MARCXML access to the Library of Congress catalogue, by translating requests into Z39.50 and querying the older system directly. As a fringe benefit, it also greatly accelerates Z39.50 access.
