Metaproxy is a proxy front end server that presents a single Z39.50/SRW/SRU front end to multiple back end database servers. It can also work in conjunction with Index Data's library of gateways to access non-standard database servers. We like to call it a "metasearch server in-a-box." It is important to note, however, that Metaproxy is server software and does not have a user interface. It is designed to easily tie into any existing standards-based interface.

Metaproxy combines caching; load balancing; filtering; and cross database merging of the result set; and other performance-enhancing mechanisms that speed up retrieval. It is designed for integrating multiple back end databases - within a single organization or across multiple organizations - into into what appears from the user's point of view to be a single searchable resource.

Native support for database access includes Z39.50, SRU, SRW, ad the SOLR webservice. If you are interested in other types of back-ends, please feel free to get in touch.
