Some of the microservices are built specifically for use with a Fedora Repository and API-X, while others are just for general use within Islandora 8. Requirements ------------ [](#requirements) The minimum requirements for any microservice are - PHP 8.0+ - [Composer](https://getcomposer.org/) Many microservices have extra installation requirements. Please see the README of each microservice for additional details. Services -------- [](#services) Crayfish contains the following services - [CrayFits](./CrayFits): FITS as a microservice. - [Homarus](./Homarus): FFmpeg as a microservice. - [Houdini](./Houdini): ImageMagick as a microservice. - [Hypercube](./Hypercube): Tesseract as a microservice. - [Milliner](./Milliner): Microservice that converts Drupal entities into Fedora resources. - [Recast](./Recast): Microservice that remaps Drupal URIs to add Fedora to Fedora links based on associated Drupal URIs in RDF. See the individual services for more information on their endpoints. Security -------- [](#security) Crayfish microservices use JWTs to handle authentication like the rest of the Islandora 8. It is disabled by default. To enable, set `security enabled` to `true` in `cfg/cfg.php` for any microservice. You can also set the path to an xml configuration file for security a la [Syn](https://github.com/Islandora/Syn/blob/main/conf/syn-settings.example.xml) with the `security config` parameter. Development ----------- [](#development) If you would like to contribute, please get involved by attending our weekly [Tech Call](https://github.com/Islandora/documentation/wiki). We love to hear from you! If you would like to contribute code to the project, you need to be covered by an Islandora Foundation [Contributor License Agreement](http://islandora.ca/sites/default/files/islandora_cla.pdf) or [Corporate Contributor License Agreement](http://islandora.ca/sites/default/files/islandora_ccla.pdf). Please see the [Contributors](http://islandora.ca/resources/contributors) pages on Islandora.ca for more information. We recommend using the [islandora-playbook](https://github.com/Islandora-Devops/islandora-playbook) to get started. If you want to pull down the submodules for development, don't forget to run `git submodule update --init --recursive` after cloning.
