## プロジェクトの歴史と使われ方

Metaproxy is Index Data's Z39.50/SRW/SRU proxy, router, and metasearch server for library and information-retrieval systems. The upstream repository identifies it as a universal Z39.50/SRU router with Index Data copyright beginning in 2005, while the product page describes it as a server that presents a single standards-based front end to multiple back-end database servers.

### プロジェクトの歴史

The technical core is a configurable routing pipeline. The manual describes Metaproxy as a standalone program that accepts requests from information-retrieval clients using protocols such as ANSI/NISO Z39.50 and SRU, acts as a client to back-end servers, and satisfies requests by transforming, multiplexing, forwarding, merging, and returning results. Its XML configuration defines routes made of filters for operations such as accepting packets, logging, query transformation, multiplexing, and SRU-to-Z39.50 translation; additional filters can be added as loadable modules.

### 採用の歴史

Its adoption niche is narrow but durable: libraries, catalogs, and discovery systems that need standards-based search interoperability. The Library of Congress documents an Index Data MetaProxy deployment as an SRW/SRU/Z39.50 gateway to its Folio and Zebra Z39.50 servers, which illustrates the kind of institutional infrastructure where the tool appears. Related documentation from the Library of Congress also explains why SRU and Z39.50 gateways matter: SRU carries Z39.50-style search semantics into web-service form.

### 使われ方

As a package-manager entry, metaproxy is specialist server software. Homebrew and MacPorts make it easier for integrators and library-system developers to install the router and its companion metaproxy-config tool on development or small deployment machines without building the YAZ-based stack by hand.
