## Introduction
This is the core module of Islandora's digital repository ecosystem. The `islandora` module provides:
- Fedora 5 integration via the [flysystem ](https://drupal.org/project/flysystem ) module
- Integration with the [context ](https://drupal.org/project/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 ](https://github.com/Islandora/Crayfish/tree/dev/Houdini ) (Imagemagick) server for image processing
- `islandora_audio` and `islandora_video`
- Integrate with a [Homarus ](https://github.com/Islandora/Crayfish/tree/dev/Homarus ) (`ffmpeg`) server for audio/video processing
- `islandora_text_extraction` and `islandora_text_extraction_defaults`
- Integrate with a [Hypercube ](https://github.com/Islandora/Crayfish/tree/dev/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 ](http://drupal.org/project/context )
- [search_api ](http://drupal.org/project/search_api )
- [jsonld ](http://drupal.org/project/jsonld )
- [jwt ](http://drupal.org/project/jwt )
- [filehash ](http://drupal.org/project/filehash )
- [prepopulate ](http://drupal.org/project/prepopulate )
- [eva ](http://drupal.org/project/eva )
- [features ](http://drupal.org/project/features )
- [migrate_plus ](http://drupal.org/project/migrate_plus )
- [migrate_source_csv ](http://drupal.org/project/migrate_source_csv )
- [flysystem ](http://drupal.org/project/flysystem )
It also requires the following PHP libraries:
- [Crayfish Commons ](https://packagist.org/packages/islandora/crayfish-commons )
- [Stomp PHP ](http://drupal.org/project/ )
If you are using a Drush version less than 10.4 you will also need to install and enable [migrate_tools ](http://drupal.org/project/migrate_tools ) separately.
## Installation
For a full digital repository solution, see our [installation documentation ](https://islandora.github.io/documentation/installation/component_overview/ ).
To download/enable just this module, use the following from the command line:
```bash
$ 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.
