Islandora

Introduction

This is the core module of Islandora's digital repository ecosystem. The islandora module provides:

• Fedora 5 integration via the flysystem module
• Integration with the context module to control your digital repository's behaviour
• Publishing messages to a queue so they can be processed in the background

islandora contains several submodules and features:

• islandora_core_feature (required)
  • Configuration required by the islandora module
• islandora_image
  • Integrates with a Houdini (Imagemagick) server for image processing
• islandora_audio and islandora_video
  • Integrate with a Homarus (ffmpeg) server for audio/video processing
• islandora_text_extraction and islandora_text_extraction_defaults
  • Integrate with a Hypercube (tessseract and pdftotext) server for text extraction
• islandora_breadcrumbs
  • Provides breadcrumbs following collection structure
• islandora_iiif
  • Provides IIIF manifests for repository content

Requirements

Installing via composer will download all required libraries and modules. However, for reference, islandora requires the following drupal modules:

• context
• search_api
• jsonld
• jwt
• filehash
• prepopulate
• eva
• features
• migrate_plus
• migrate_source_csv
• flysystem

It also requires the following PHP libraries:

• Crayfish Commons
• Stomp PHP

If you are using a Drush version less than 10.4 you will also need to install and enable migrate_tools separately.

Installation

For a full digital repository solution, see our installation documentation.

To download/enable just this module, use the following from the command line:

$ composer require islandora/islandora
$ drush en islandora_core_feature
$ drush mim islandora_tags

Configuration

You can set the following configuration at admin/config/islandora/core:

• Broker URL
  • The URL to your message broker (i.e. Activemq)
• JWT Expiry
  • Set to increase the amount of time that authorization tokens remain valid. If you have a long running derivative processes or a migration, you may need to set this to be a very long time, e.g. 500d. Otherwise, it's best to leave it alone.
• Gemini URL
  • The URL to your Gemini server, which keeps track of where Islandora content is in Fedora.
• Fedora URL Display
  • Selected bundles can display the Fedora URL for repository content.

Documentation

Further documentation for this module is available on the Islandora 8 documentation site.
