CQL-Java
CQL parser for Java.
Free/proprietary/other: Free
Licence: GNU LGPL
Download link: http://zing.z3950.org/cql/java/
Support: informal support available; commercial arrangements
possible with Index Data.
System requirements: Java. I've used version 1.4.1 of IBM's
JRE, but it doesn't use any sophisticated runtime facilities, so it
should be fine on any runtime environment.
Language: Java
Known servers that run this software:
Usage: The front end reads a stream containing a CQL
query and produces a parse-tree represented by simple, well-documented
node objects. This can either be walked by hand, or fed to one
of the provided back ends, which produce XCQL (an XML representation
of the query), re-rendered canonicalised CQL, PQF (Prefix Query
Format representing an equivalent Z39.50 Type-1 Query) or a raw
BER-encoded Type-1 Query.

Proxies
YAZ Proxy
The YAZ proxy can run as a front-end to any Z39.50 server and provide
SRU/SRW services (as well as Z39.50 services). The mapping between CQL
and the Z39.50 type-1 query language is fully configurable. It can map
MARC
records to MARCXML and other transformations can be performed using XSLT
stylesheets (stylesheets for DC and MODS are included). The proxy can
normalize different character sets to UTF-8 as required. In addition
to its
SRU functionality it also includes a host of performance-optimization
features such as caching and load management.
Version: 1.0
Free/proprietary/other: Free
License: GPL. Other licenses are available on request.
Download link: http://www.indexdata.com/yazproxy/
Support: Available. http://www.indexdata.dk/support/

Product lines
Archimed
Archimed products implementing SRW/U are:
- QuASAR. Windows client (.Net). used for quick testing and analyzing of the SRW/U services: version of the protocol, index, format of answers, etc. Available free of charge on (French)
- SARA. A universal SRW/U server. Can run on Windows (.Net) or Linux (Mono::). It aims at quickly developing plugs-in to interface in SRW/U databases or application not natively searchable with this protocol. Several plugs-in have already been developed, to search with SARA, the following databases or systems: DMOZ, XML files, Index Server, Copernic, WebDav (WebFolder and Exchange), Wiley InterScience, IOP, PubMed, Nature, ScienceDirect, etc. The diversity of sources that can be linked by SARA through the SRW/U protocol makes SARA the adequate tool to normalise access to heterogeneous proprietary systems.
- BOOK-LINE. A multibase meta search engine interrogating the databases equipped with a Z39.50 and SRW/U footbridge. Combined with SARA, BOOK-LINE can query in one search all native Z39.50 or SRW/U databases and all heterogeneous sources queried in SRW/U.
QuASAR is now available only in French.

RefDB
RefDB is a reference database and bibliography tool for SGML, XML, and LaTeX documents. Command-line tools allow interactive or scriptable access to the data which are stored in a SQL database. RefDB can also be accessed through a Web interface, a SRU interface, or via editor extensions (Emacs/vim). Libraries for Perl and PHP are available for programmers. RefDB provides sophisticated character encoding handling, using Unicode by default. The SRU server is a CGI application which supports both MODS and risx (a RIS variant encoded as XML) as output formats. Appropriate default stylesheets are provided to make the results human-readable in a web browser.
Version(s) of the product. The current version 0.9.9 is
the first one that supports SRU.
Version(s) of SRU, CQL, supported. SRU version 1.2 (explain, searchRetrieve,
and scan are implemented) CQL
level 2.
Free/proprietary/other. Free.
License. GNU General Public License.
Homepage: http://refdb.sourceforge.net
Download link. http://sourceforge.net/projects/refdb
Support. via mailing list: http://lists.sourceforge.net/lists/listinfo/refdb-users
System requirements. As far as the SRU server is concerned,
a web server like Apache and a Perl interpreter with a couple of
Perl modules suffice. The RefDB
application server runs on most Unix variants (Linux, FreeBSD,
NetBSD,
OSX, Solaris) and on Windows/Cygwin. Data are stored in a
SQL database
(MySQL, PostgreSQL, and SQLite are supported).
Language. The SRU server
part of RefDB is
implemented as a Perl CGI application.
Known servers that run this software. No public servers
to date.
Usage. The SRU server part acts as a proxy server for
the RefDB application
server. As a CGI application, it plugs right into your web
server. You send your SRU queries by typing them into a web
browser, via command line tools
like wget, via tools like yaz, or by running applications
that send SRU
request. Your web server then calls the CGI application which
returns the
query results.

- Metaproxy
A proxy front end server that presents a single Z39.50/SRW/SRU front
end to multiple back end Z39.50 database servers. It can also work in
conjunction with Index Data's library of gateways to access non-Z39.50-compliant
database servers. Metaproxy is server software and does not have a client
interface but is designed to tie into any existing client search interface.
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 what appears from the user's point of view to be a single searchable
resource.
Distributed under the General Public License.
- PHP/YAZ
An extension to PHP, the web server language that implements Z39.50 origin (client) functionality as well as the SRW/SRU protocols.
Distributed under the PHP license.
- SIMPLESERVER
A Perl
module intended to make it as simple as possible to develop
new Z39.50, SRU and SRW servers over any type of database.
Available under the BSD license.
- YAZ ++
Toolkit for building Z39.50/SRU clients and servers. An application programming interface to YAZ which supports the development of Z39.50/SRW/SRU client and server applications using C++. Supports SRW/SRU version 1.1 in both the client and server roles. Includes an implementation of the ZOOM C++ binding and a generic client/server API based on the Observer/Observable design pattern.
Available under the BSD license and optional support is available from Index Data.
- YAZ Proxy
Configurable Z39.50 proxy server and SRW/SRU--Z39.50 gateway and can be used in a number of different applications.
