This paper describes the main features of the Renardus cross-search and cross-browse service. Renardus is made up of a number of participating subject gateway services. Cross searching is based on the Z39.50 protocol. A review of data models in use by partner services helped define a minimum set of Dublin Core-based metadata elements that could be utilised as a common model for the Renardus service. This provides the basic infrastructure for interoperability between all participating gateways. The Renardus Service also uses classification mapping to enable subject browsing across all gateways with the Dewey Decimal Classification (DDC). The paper outlines the use of classification systems by Renardus partner gateways, the general mapping approaches taken by the project, the definition of mapping relationships, and technical solutions. There follows a description of how the mapping information is used within Renardus and several features that have been implemented to aid end-user navigation in deep subject-browsing structures.
