Page History

The Fedora Repository makes it possible to design custom event-driven application workflows. For instance, a common use case is sending content to an external search engine or triplestore. Other repositories may wish to generate derivative content such as creating a set of smaller images from a high-resolution master.

Karaf can be set up by:

1. downloading Karaf 4.x or later from an apache.org mirror
2. running ./bin/karaf to enter the shell

3. installing required bundles (n.b. the following commands correspond to Karaf 3.x. For Karaf 2.x installations, please refer to the Karaf 2.x documentation):
   
   

   Code Block
   language bash title Karaf console
   $> feature:repo-add camel 2.1416.02 $> feature:repo-add activemq 5.1011.01 $> feature:install camel $> feature:install activemq-camel # display available camel features $> feature:list | grep camel # install camel features, as needed $> feature:install camel-http4   # install fcrepo-camel (as of v4.14.0) $> feature:repo-add mvn:org.fcrepo.camel/fcrepo-camel/4.14.0/xml/features $> feature:install fcrepo-camel

4. setting up a service wrapper (so that karaf runs as a system-level service)
   
   

   Code Block
   language bash title Karaf console
   $> feature:install wrapper $> wrapper:install

5. following the directions provided by this command

Now, routes can be deployed (and re-deployed) by simply copying JAR files or XML documents to $KARAF_HOME/deploy.

Fedora Camel Toolbox

The Fedora project distributes camel routes for several common repository tasks as part of the fcrepo-camel-toolbox project, for use with Karaf version 4.x. Additional information is available on the Integration Services page. Detailed installation instructions are available as part of the project README and follow this pattern:

# install fcrepo-camel-toolbox (as of v4.1.0)
$> feature:repo-add mvn:org.fcrepo.camel/fcrepo-camel-toolbox/4.1.0/xml/features
 
# install fcrepo-camel-toolbox (as of v4.5.0)
$> feature:repo-add mvn:org.fcrepo.camel/toolbox-features/4.5.0/xml/features
 
# display available features
$> feature:list | grep fcrepo
 
# install feature
$> feature:install fcrepo-indexing-triplestore
