MIX Metadata Enrichment Plugin

This Step plugin for Goobi workflow uses JHove to extract technical metadata from files and save the results into the METS file of a Goobi process.

Overview

Introduction

This documentation explains the plugin for enriching MIX Metadata.

Installation

To be able to use the plugin, the following files must be installed:

/opt/digiverso/goobi/plugins/step/plugin-step-mix-metadata-enrichment-base.jar
/opt/digiverso/goobi/config/plugin_intranda_step_mix_metadata_enrichment.xml
/opt/digiverso/goobi/config/jhove/jhove.conf

Once the plugin has been installed, it can be selected within the workflow for the respective work steps and thus executed automatically. A workflow could look like the following example:

To use the plugin, it must be selected in a workflow step:

Overview and functionality

When the plugin is executed, all image files in the configured folders are analyzed with JHove and the technical metadata is extracted in MIX format. This technical metadata is then added to the Mets file of the process and linked there to the respective image files.

Configuration

The plugin is configured in the file plugin_intranda_step_mix_metadata_enrichment.xml as shown here:

<config_plugin>
    <!--
        order of configuration is:
          1.) project name and step name matches
          2.) step name matches and project is *
          3.) project name matches and step name is *
          4.) project name and step name are *
	-->
