Installation

Program Libraries

The installation consists of a total of four program libraries that must be accessible in Apache Tomcat or Goobi:

FileLocation

layoutwizzard.jar

In the lib folder of the Goobi webapp in the Tomcat

plugin_intranda_step_LayoutWizzard.jar

In the plugins/step folder in the Goobi working directory

plugin_intranda_step_LayoutWizzard-GUI.jar

In the plugins/GUI folder in the Goobi working directory

Configuration files

In addition to these program files, two configuration files are required, one for the Goobi plug-in and one for the underlying LayoutWizzard program library.

Plugin configuration

The configuration file of the plugin plugin_LayoutWizzardPlugin.xml must be located in the config configuration directory within the Goobi working directory. This is usually the path to the file:

/opt/digiverso/goobi/config/plugin_LayoutWizzardPlugin.xml

Within this configuration file the path to the actual central configuration of the LayoutWizard is specified. The structure of this file looks like this:

<!-- Goobi Plugin configuration file -->
<config_plugin>
	<config>
		<!-- which projects to use for (can be more then one, otherwise use *) -->
        <project>*</project>
        <!-- which steps to use for (can be more then one, otherwise use *) -->
        <step>*</step>
        
        <!-- The absolute path to the layoutwizzard_config.xml to use -->
	    <layout-wizzard-config-path>
	        /opt/digiverso/LayoutWizzard/layoutwizzard_config.xml
	    </layout-wizzard-config-path>
	    
	    <!-- The initial view of the LayoutWizzard Plugin. Can be one of

LayoutWizzard configuration

The actual configuration file specifies various parameters for the layout analysis process. These parameters are listed as examples in the following configuration file. As defined in the plugin configuration file, it is located under the following path:

/opt/digiverso/intranda/LayoutWizzard/layoutwizzard_config.xml

As an example, this configuration file has the following content:
