DeepaMehta 2 Poemspace Exporter

This web application demonstrates how to export content from a DeepaMehta 2 installation in order to import it to DeepaMehta 3.

Please Note:
This is not a universal DeepaMehta 2 exporter.
DeepaMehta 2 Poemspace Exporter is tailored for a specific custom data model.
Without modification this will not run with your DeepaMehta 2 installation.

However, if you plan to transfer DeepaMehta 2 content to DeepaMehta 3 this application might serve you as a good starting point.

Requirements

• A DeepaMehta 2 installation
  http://www.deepamehta.de

• Tomcat (or another Servlet engine)
  http://tomcat.apache.org/

• Ant
  http://ant.apache.org/

Installation

1. Clone the Git repository to your computer git clone git://github.com/jri/dm2-poemspace-exporter.git A directory dm2-poemspace-exporter will be created. Go there: cd dm2-poemspace-exporter

2. Configure two servlet context parameters in file web.xml (found at top-level):
   home - the home directory of your DeepaMehta installation, e.g. /usr/local/deepamehta2.
   service - the DeepaMehta instance you want to export, e.g. default.

3. Build with ant ant The file dist/poemspace-exporter.war will be created.

4. Move poemspace-exporter.war to your Tomcat webapps directory, e.g.: mv dist/poemspace-exporter.war /var/lib/tomcat/webapps

Usage

1. Start the export process by pointing your webbrowser to (replace localhost:8080 with your Tomcat host and port): http://localhost:8080/poemspace-exporter/export No further interaction is required. The export process might take a while.

2. Track the export process by reading the Tomcat log, e.g.: cd /var/log/tomcat-6 tail -f catalina.2009-10-18.log Once the export is complete a respective message appears in the log:
   #################### export complete ####################

3. The result of the export is a file dm2-export.json which is created in Tomcat's temporary directory, e.g. /var/tmp/tomcat-6

4. You can import that file to DeepaMehta 3 by means of the "DM3 Import" plugin.
