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:

  • 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

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.
