Islandora Open Migrate

Introduction

Demonstration module to show off Drupal Migrate and DGI's tooling.

Requirements

This module requires the following modules/libraries:

Installation

Install as usual, see this for further information.

Configuration

Using the supplied sample data, extract it on the server as follows:

cd /usr
tar -xvf cookie_fedora.tar.gz

This will extract our pseudo FCREPO3 data in a place that a mount would live.

Next chown and chmod the files to ensure Drupal can read them only:

sudo chown -R www-data:root /usr/local/fedora
sudo chmod -R a=rX /usr/local/fedora

NOTE: This is purely for demonstration purposes and I would suggest not doing this directly on a mount. Consult a qualified dev-ops resource.

Make an entry in the Drupal settings file to allow the akubra_adapter to read the newly extracted data:

$settings['akubra_adapter_datastream_basepath'] = '/usr/local/fedora/data/datastreamStore';
$settings['akubra_adapter_object_basepath'] = '/usr/local/fedora/data/objectStore';

If everything has been set up correctly if you run drush migrate-status --group=foxml_to_islandora_open you should see the following:

sudo -u www-data /opt/www/drupal/vendor/bin/drush ms --group=foxml_to_islandora_open

For ease of running use the included helper scripts from within dgi_migrate. Create a folder to house log outputs as well as the environment file.

cd /opt/www/drupal
mkdir islandora_open_migrations
cd islandora_open_migrations
cp /opt/www/drupal/modules/contrib/dgi_migrate/scripts/env.sample .env

Open the .env in your favorite text editor and enter values for both the MIGRATION_GROUP and URI:

# ===
# MIGRATION_GROUP: The migration group on which to operate.
#
# No default, as there is nothing sane to provide as a default.
# ---
MIGRATION_GROUP=foxml_to_islandora_open

# ===
# WEB_USER: The user as whom to invoke drush; must have access to JWT keys and
# the like.
# ---
#WEB_USER=www-data

# ===
# URI: The URI of the target site. Must be externally dereferenceable, as this
# is likely used to generate externally links, and derivatives and the like.
# ---
# NOTE: URI has no default, and _must_ be provided by all sites.
URI=http://tophat-i9manage-dev.dev.dgi

The migration is now ready to be run by executing the following:

bash /opt/www/drupal/modules/contrib/dgi_migrate/scripts/migration.sh /opt/www/islandora_open_migrations

The output of the migration can be viewed in the logs that are generated in the directly made and also includes any messages from within the migration's tables in JSON format.

Lastly migrations can be rolled back by doing the following:

bash /opt/www/drupal/modules/contrib/dgi_migrate/scripts/rollback.sh /opt/www/islandora_open_migrations
