1. In the existing eagle-i home directory (the parent of the repository home-directory, ${REPO_HOME}) create a directory "sparqler", and set an environmental variable ${SPARQLER_HOME}.   For example, if the repository home is /opt/eaglei/repo, then the sparqler home would be /opt/eaglei/sparqler.
2. Copy the file ${REPO_HOME}/webapps/sparqler.war to Tomcat's webapps directory.
3. Add an additional system property to catalina.properties:

   No Format
   org.eaglei.sparqler.home=/opt/eaglei/sparqler

4. Run the script ${REPO_HOME}/etc/prepare-install.sh with an additional argument: "sparqler-users.derby" (note that the username and password for the user you create here - who administers the sparqler - these should be different from the main repository's admin-user credentials):

   No Format
   bash ${REPO_HOME}/etc/prepare-install.sh SPARQLER_USERNAME SPARQLER_PASSWORD ${REPO_HOME} sparqler-users.derby

5. Create and edit the repository configuration file (${SPARQLER_HOME}/configuration.properties) - it should be identical to the main repository's config-file, with the following two exceptions - we set:

   No Format
   eaglei.repository.sesame.dir=${sys:org.eaglei.sparqler.home}/sesame eaglei.repository.log.dir=${sys:org.eaglei.sparqler.home}/logs

6. Start up Tomcat
7. Run the script ${REPO_HOME}/etc/finish-install.sh, using the same sparqler-admin username and password that you set up in step 1, above, when you ran the "prepare-install.sh":

   No Format
   bash ${REPO_HOME}/etc/finish-install.sh SPARQLER_USERNAME SPARQLER_PASSWORD https://localhost:8443/sparqler

...

The sparqler repository keeps itself up-to-date with its source-repository by running a nightly periodic synchronization process.  This is run automatically so long as the sparlqer and its source-repository are running - no intervention is required.

If you run on Windows (warning: this is at your own risk - we have not tested the system on Windowsexplicitly unsupported), you should set up a Unix-like environment (e.g. Cygwin) in which to perform the installation and run the shell-scripts.       --------------------------------------------------------------------------------------------------------------------------------------------------------------------------
