This project contains the canonical resources to build the backend for a corpus/repository management framework which serves data over a REST API. This is built on the Drupal CMS, following conventions of Entity API, Search API, and the REST API, and its configuration/implementation should present no surprises for developers familiar with Drupal.

From a fresh installation, the database schema will provide a text entity type, which holds the corpus text data and metadata, and a repository entity type, which references materials related to the texts. These entity types and the metadata they contain can be modified or extended as needed to fit the individual corpus.

The configuration provided subsequently includes search indices for texts and repository materials, and a REST API for performing keyword or metadata searches against the dataset.

This codebase does not make any assumptions about the way the data provided by the API is displayed (in a frontend).

Developing your own version of this site assumes familiarity with, and local installation of, the [Composer(https://getcomposer.org/) package manager. This repository contains only the "kernel" of the customized code & configuration. It uses Composer to build all assets required for the site, including the Drupal codebase and a handful of corpus-related PHP libraries.

Run composer install from the document root. This will build all assets required for the site. That's it!

The following assumes familiarity with local web development for a PHP/MySQL stack. Since Drupal is written in PHP and uses an SQL database, that means you'll need:

• PHP 5.5.9 or higher. See Drupal 8 PHP versions supported.
• A database server (MySQL, PostgreSQL, or SQLlite that meets the minimum Drupal 8 requirements).
• A webserver that meets the minimum PHP requirements above. Typically, this means Apache, Nginx, or Microsoft IIS. See Drupal webserver requirements.

There are a number of pre-packaged solutions that simplify setup of the above. These includes MAMP, Valet, and Lando.

1. cp sites/example.settings.local.php sites/default/settings.local.php
2. Create a MySQL database, then add its connection credentials to the newly created settings.local.php. Example:

$databases['default']['default'] = [
  'database' => 'MYSQL_DATABASE',
  'username' => 'MYSQL_USERNAME',
  'password' => 'MYSQL_PASSWORD',
  'host' => 'localhost',
  'port' => '3306',
  'driver' => 'mysql',
  'prefix' => '',
  'collation' => 'utf8mb4_general_ci',
];

3. Either navigate to your local site's domain and follow the web-based installation instructions, or if you prefer to use drush, run the drush site-install command.
4. That's it! After signing in at /user, you should see the two available entity types at /node/add, the available metadata references at /admin/structure/taxonomy and the search configuration at /admin/config/search/search-api

Properly prepared text files can be imported via a drag-and-drop interface at /admin/config/media/import

Each text file needs to include the metadata elements in the file, followed by the actual text to be indexed. A model for that file structure is below:

Alternative to the UI import, a directory of local text files can be imported via the drush corpus-import command. Example usage:

drush corpus-import /Users/me/myfiles/

All API requests require basic HTTP authorization. Contact the corpus maintainers for access.

All endpoints are accessible via https and are located at writecrow.corporaproject.org, and can return data in either XML or JSON format. An example request for all texts matching a given ID, in JSON format, would look like this:

https://api.writecrow.org/texts/id?id=10533&_format=json
