[[http://www.loc.gov/standards/sru/|Search/Retrieval via URL (SRU)]] is a specification for searching resources that relies on standard Web technology (HTTP, XML) for its implementation. Evergreen 1.4 supports basic SRU access through the /opac/extras/sru service defined in the Apache ''eg_vhost.conf'' configuration file and implemented in the sru_search() method in [[http://svn.open-ils.org/trac/ILS/browser/trunk/Open-ILS/src/perlmods/OpenILS/WWW/SuperCat.pm|Open-ILS/src/perlmods/OpenILS/WWW/SuperCat.pm]]. | [[http://www.loc.gov/standards/sru/|Search/Retrieval via URL (SRU)]] is a specification for searching resources that relies on standard Web technology (HTTP, XML) for its implementation.

</code> You can have multiple **<database>** sections in a single file, each pointing to a different scope of your consortium. The **name** attribute on the **<database>** element is used in your Z39.50 connection string to name the database. The **<zurl>** element must point to ''http://hostname/opac/extras/sru''. As of Evergreen 1.6, you can append an optional organization unit shortname for search scoping purposes, and you can also append **/holdings** if you want to expose the holdings for any returned records. So your zurl could be ''http://dev.gapines.org/opac/extras/sru/BR1/holdings'' to limit the search scope to BR1 and its children, and to expose its holdings. | </code> You can have multiple **<database>** sections in a single file, each pointing to a different scope of your consortium.

Along the way, we force the output character set to be MARC-8, because in the dinosaur world of library technology some major Z39.50 clients such as RefWorks and OCLC VDX still appear to be unable to support Unicode UTF-8 encoding.
