This module utilizes Zorba to run XQueries against XML documents stored in Fedora.

In addition to a functioning Islandora instance with the Libraries API, this module requires the following modules/libraries:

• An XQuery processor, one of:
  • Zorba; or,
  • BaseX
• libxdiff
• PHP xdiff Extension
• GeSHi
• Islandora Object Lock

Example installation scripts:

• Ubuntu 12.04
• Ubuntu 18.04 and RedHat/Centos 7

Your mileage may vary with other distros/versions. These scripts will handle installing the islandora_xquery module and all of its dependencies. It assumes that you have a functioning Islandora install with Drush.

Basic Algorithm:

• Install XQuery processor
• Compile libxdiff from source (./configure, make, make install)
• Install PHP xdiff extension
• Install GeSHi using the Libraries API (put geshi folder in sites/all/libraries)
• Install Islandora Object Lock Module
• Install Islandora Xquery Module

At installation time, it may be necessary to select and configure the XQuery processor to be used at admin/islandora/tools/xquery/manage/processor.

Templates can be added for re-use at admin/islandora/tools/xquery/manage.

The default Zorba implementation uses the Saxon processor, which WILL unescape your xml entities! For example, even the lowly identity transform will change <dc:title>&quot;Things and Stuff&quot;</dc:title> to <dc:title>”Things and Stuff”</dc:title>. You will get some brand spanking new quotes you never asked for! You’ve been warned!
