Developers who need to translate metadata now have access to a new demonstration service.
OCLC Crosswalk Web Service translates metadata records from one format to another and will process up to 500 records from all requests per user, per day. With the aid of the WSDL file, users can develop a client to access the service, which is available on the OCLC ResearchWorks Web site for an undecided duration.
This page includes links to a variety of MARC documents, including formats and code lists. Also has links to various mappings (crosswalks) to and from MARC.
