Learning Outcomes

• Deploying Fedora
• Explore core and external features
• Gain insight into content modeling
• Set up a federation over a local filesystem
• Set up JMS message consumer
• Set up external triplestore(PCDM)

Prerequisites

Either

1. Vagrant setup:
   • Download and install VirtualBox: https://www.virtualbox.org/wiki/Downloads
   • Download and install Vagrant: http://www.vagrantup.com/downloads.html
   • Download the Fedora 4 VM: https://github.com/fcrepo4-labs/fcrepo4-vagrant
     • Note that you can either clone the repository to your desktop or just download the ZIP [2] and unzip it
   • Using a Command Line Interface, navigate to the VM folder from step 3 and run the command: vagrant up
     • Note that this step will take a while as the VM downloads and installs a virtual environment
   • Test the VM by opening your web browser and navigating to: http://localhost:8080/fcrepo
2. Or, Standalone apps setup:
3. Java7 installed
4. WAR file(s) downloaded
5. Configuration files downloaded
6. Tomcat installed (optional)

Downloads

War files

Required

• One click run of Fedora 4: fcrepo-webapp-4.1.1-jetty-console.war
• One click run of external message consumer: fcrepo-message-consumer-webapp-4.1.1-jetty-console.war

Optional

• fcrepo-message-consumer-webapp-4.1.1.war (optional, only needed if deploying to Tomcat)
• fcrepo-webapp-4.1.1.war (optional, only needed if deploying to Tomcat)

Triplestore

• Download and unpack Jena Fuseki (ZIP or TAR) prior to the training

Deploying Fedora4

In OSX or Windows you can simply double-click the fcrepo-webapp-4.1.0-auth.war file to launch the Fedora 4 console. Then click Start and wait for the application to load in your browser.

You can also run the application from the command line using the following command:

java -jar fcrepo-webapp-4.1.0-jetty-console.war --headless

Note: The location where Fedora writes to disk can be specified with the following flag:

2. Select Dataset "/test"
3. Select Output "Text"
4. Select "Force the accept header text/plain regardless"

5. Query

   No Format
