SRU uses a fairly simple query language called <a class="ulink" href="http://www.loc.gov/standards/cql/index.html" target="_top">CQL</a> (Contextual Query Language). Any program that can send a HTTP GET request to a remote site and receive the resulting XML document is basically suited as a SRU client. This is especially true for your web browser and for command-line utilities like <a class="ulink" href="http://www.gnu.org/software/wget/" target="_top">wget</a>, but a dedicated client like <a class="ulink" href="http://www.indexdata.dk/yaz" target="_top">YAZ</a> may be more convenient for all but the most simple queries. Also, some software packages read bibliographic data from databases via SRU (e.g. <a class="ulink" href="http://xbiblio.sourceforge.net/citeproc/" target="_top">citeproc</a>).</p><p>RefDB implements SRU server capabilities through a <a class="link" href="re04.html" title="refdbsru">CGI script</a> that you can optionally install in your web server. This will allow anyone with access to your web server to search and retrieve bibliographic data in your RefDB databases. Alternatively, a standalone web server for single-user access is available too. This chapter explains how to use SRU access. See the <a class="link" href="ch04s10.html" title="SRU support">installation chapter</a> for the instructions how to set up SRU support in your RefDB installation.</p></div></div><div class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="ch10s06.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="pt03.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="ch11s02.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Using custom stylesheets to process documents with bibliographies </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> SRU Operations</td></tr></table></div></body></html>
