Installation

Programmbibliotheken

Die Installation besteht aus insgesamt vier Programmbibliotheken, die im Apache Tomcat bzw. in Goobi erreichbar sein müssen:

DateiSpeicherort

layoutwizzard.jar

Im lib-Ordner der Goobi webapp im Tomcat

plugin_intranda_step_LayoutWizzard.jar

Im Ordner plugins/step im Goobi-Arbeitsverzeichnis

plugin_intranda_step_LayoutWizzard-GUI.jar

Im Ordner plugins/GUI im Goobi-Arbeitsverzeichnis

Konfigurationsdateien

Neben diesen Programmdateien werden zwei Konfigurationsdateien benötigt, eine für das Goobi-Plugin, und eine für die zugrundeliegende LayoutWizzard-Programmbibliothek.

Plugin-Konfiguration

Die Konfigurationsdatei des Plugins plugin_LayoutWizzardPlugin.xml muss im Konfigurationsverzeichnis config innerhalb des Goobi-Arbeitsverzeichnisses liegen. Üblicherweise handelt es sich hierbei um diesen Pfad zur Datei:

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

Innerhalb dieser Konfigurationsdatei wird der Pfad zur eigentlichen zentralen Konfiguration des LayoutWizzards angegeben. Der Aufbau dieser Datei sieht dabei folgendermaßen aus:

<!-- 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
	    	* PREVIEW: The preview page of the plugin, displaying all pages in a vertical list

	    	* SIMPLECROP: A zoomable cropping view for processes with few large images. Does not support spne cropping-->
	    <startPage>PREVIEW</startPage>
	    
	    <!-- The initial viewing mode if the PREVIEW view. One of

	        * DOUBLE_PAGE to see opposite pages next to each other -->

LayoutWizzard-Konfiguration

Die eigentliche Konfigurationsdatei gibt für den Vorgang der Layoutanalyse verschiedene Parameter vor. Diese Parameter sind beispielhaft in der folgenden Konfigurationsdatei aufgeführt. Sie befindet sich, wie in der Plugin-Konfigurationsdatei definiert, unter folgendem Pfad:

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

Beispielhaft hat diese Konfigurationsdatei den folgenden Inhalt:
