A PHP API to Wikisources (all languages).

2.0.6 2023-09-18 05:06 UTC


Wikisource API

This is an client API library for retrieving data from Wikisources. It uses data from Wikidata where it can, or MediaWiki API data from specific Wikisources, or resorts to scraping HTML where that's the only option.


Features (some are in development and are not yet functional):

  • List all Wikisources.
  • Get metadata about a single Wikisource: language code, language name (in that language), and information about namespaces (their names and IDs).
  • List all Works in a Wikisource.
  • Get metadata about a single Work on a Wikisource: URL, page name, work title, author, year of publication, proofreading quality, and a list of Index Pages used by the Work.
  • Get metadata about a single Index Page on a Wikisource: URL, page name, list of Pages, and proofreading quality.
  • Get metadata about a single proofreading Page on a Wikisource (i.e. a wiki-page in the Page namespace): URL, wiki-page name, page number (in Djvu/PDF), page label (in the Index's page-list), and proofreading quality.


Install with Composer:

$ composer require wikisource/api

You might also want something that implements psr/log and something that implements psr/cache, if you want to use the logging and caching features of this library.


Find all Wikisources:

$wsApi = new \Wikisource\Api\WikisourceApi();
$wikisources = $wsApi->fetchWikisources();

Get a single work:

$wsApi = new \Wikisource\Api\WikisourceApi();
$enWs = $wsApi->fetchWikisource('en');
$prideAndPrejudice = $enWs->getWork('Pride and Prejudice');
echo $work->getWorkTitle().' was published in '.$work->getYear();

Let it cache results, such as the seldom-changing list of available Wikisources as derived from Wikidata (any implementation of PSR-6 works here):

$wsApi = new \Wikisource\Api\WikisourceApi();
$cache = new Pool(new FileSystem(['path' => __DIR__.'/cache']));

See the examples/ directory for fully-functioning examples that you can run straight away from the command line.


Every external request that this library performs will be cached if you provide a cache pool via WikisourceApi::setCache(). The default cache times are as follows:

Data Default lifetime Override
List of Wikisources 30 days Parameter to WikisourceApi::getWikisources()
Index Page metadata 1 hour Parameter to IndexPage::__construct()
A Work's Wikidata Item number 1 day Not possible


You can enable logging by passing WikisourceApi::setLogger() any object that implements PSR-3's LoggerInterface.


Please report all issues via Phabricator (tag them with the 'wikisource-api' project).
