## 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

- [context](http://drupal.org/project/context)
- [search_api](http://drupal.org/project/search_api)
- [jsonld](http://drupal.org/project/jsonld)

- [features](http://drupal.org/project/features)
- [migrate_plus](http://drupal.org/project/migrate_plus)
- [migrate_tools](http://drupal.org/project/migrate_tools)
- [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/)

## 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.
