Ross wants to use A9’s OpenSearch for metasearch, but he doesn’t want his client to have to handle four metadata standards. Bruce doesn’t want to maintain his own citation database at all, and proposes XSLT extensions to handle retrieving citations from remote servers. Why not insert remote services into the pipeline, that retrieve records in any format and pass them on in any other? A metadata-crosswalk proxy? YAZ Proxy does some of this for MARC already, and XSL lets us build easy-to-maintain tools.
