The package allows for the creation, maintenance, dissemination, and usage of structured data in MediaWiki. High level documentation can be found on [wikiba.se](https://wikiba.se/) and [mediawiki.org](https://www.mediawiki.org/wiki/Wikibase). Lower level documentation can be found on doc.wikimedia.org [here](https://doc.wikimedia.org/Wikibase/master/php/). Install ------- [](#install) Wikibase depends on various [composer](http://getcomposer.org/) libraries. Once you have Wikibase in your MediaWiki extensions directory, go to the root of your MediaWiki folder, and if `composer.local.json` does not yet exist there, copy `composer.local.json-sample` to `composer.local.json`(see [MediaWiki's Composer documentation](https://www.mediawiki.org/wiki/Composer#Using_composer-merge-plugin)). Then run: ``` composer install ``` If you already ran `composer install` during the installation of MediaWiki, run instead: ``` composer update ``` > When using ways to combine MediaWiki with the extension folders (e.g. symlinks or docker volumes) please make sure that the folders are available to composer in the same structure they are available to the webserver, too. This will install both Wikibase Client and Repo together on the same wiki. If you want to only have one or the other, then set `$wgEnableWikibaseRepo = false` or `$wgEnableWikibaseClient` to false for the one you don't want to enable. Wikibase also depends on several JavaScript libraries. They are included in this repository as submodules. To fetch files of these libraries, you might need to run, in the Wikibase extension folder, the following command: ``` git submodule update --init ``` ### Development [](#development) Wikibase uses tools to ensure the quality of software developed. To invoke these tools, inside the Wikibase folder, run: ``` composer install composer run-script test ``` > As this uses development dependencies and custom configuration, executing it from the MediaWiki root folder (via `composer run-script test extensions/Wikibase`) will not work satisfactorily #### JavaScript [](#javascript) Wikibase makes use of frontend software from various eras - resulting in a heterogenous technological landscape. Some notable (not a comprehensive list) mentions are - the use of [ResourceLoader](https://www.mediawiki.org/wiki/ResourceLoader) to - allow for concatenation and minification of code neatly organized in separate files - translate less to CSS - model module inter-dependencies - handle delivery to the client through MediaWiki - use of the [Javascript interfaces exposed by MediaWiki](https://www.mediawiki.org/wiki/Manual:Interface/JavaScript); e.g. `mw.hook` in [EntityInitializer](./repo/resources/wikibase.EntityInitializer.js) - frontend components making heavy use of jQuery; e.g. for so called [experts](repo/resources/experts/Entity.js) - the use of qunit to test this code; e.g. in `repo/tests/qunit`, available [via a special page](https://www.mediawiki.org/wiki/Manual:JavaScript_unit_testing) - [vue.js](https://vuejs.org/guide/introduction.html) as a frontend framework; e.g. in [data-bridge](./client/data-bridge), the [Lexeme](https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/WikibaseLexeme/) extension, and [termbox](https://gerrit.wikimedia.org/g/wikibase/termbox) #### Adding language code support in Wikibase [](#adding-language-code-support-in-wikibase) To add support for a new language code (for labels or monolingual text) please refer to the [detailed documentation](https://www.mediawiki.org/wiki/Manual:Adding_and_removing_languages#Wikibase). ### Health Score 53 — FairBetter than 96% of packages Maintenance64 Regular maintenance activity Popularity43 Moderate usage in the ecosystem Community36 Small or concentrated contributor base Maturity63 Established project with proven stability Bus Factor4 4 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
