[Professional Wiki](https://professional.wiki) created and maintains Wikibase RDF. We provide [Wikibase hosting](https://professional.wiki/en/hosting/wikibase), [Wikibase development](https://professional.wiki/en/wikibase-software-development), and [Wikibase consulting](https://wikibase.consulting/). The [Wikibase Stakeholder Group](https://wbstakeholder.group/) conceived and funded the extension. **Table of Contents** - [Usage](#usage) - [REST API](#rest-api) - [Installation](#installation) - [PHP Configuration](#php-configuration) - [Development](#development) - [Release notes](#release-notes) Usage ----- [](#usage) When the extension is enabled, Item and Property pages show a "Mapping to other ontologies" section. This section is located between the "In more languages" and "Statements" sections. [![Property page with a mapping](https://user-images.githubusercontent.com/146040/193851219-dc30080a-7cbb-4c1a-9800-e7c7d98ef644.png)](https://user-images.githubusercontent.com/146040/193851219-dc30080a-7cbb-4c1a-9800-e7c7d98ef644.png) Users with editing permissions can add, edit, or remove mappings. A mapping consists of a predicate and a URL. The predicate can only be one out of a preconfigured set of values. The URL has to be valid. [![Mapping editing UI](https://user-images.githubusercontent.com/146040/193851211-b4031ca1-4cc9-47ab-9160-658f4a38d979.png)](https://user-images.githubusercontent.com/146040/193851211-b4031ca1-4cc9-47ab-9160-658f4a38d979.png) Mapping predicates can be configured via the `MediaWiki:MappingPredicates` page by anyone with interface-admin permissions. You can also configure mapping predicates via [PHP Configuration](#php-configuration). [![Mapping predicates configuration page](https://user-images.githubusercontent.com/146040/193851215-86b8ad05-0c1a-431c-ad4b-5750997fd642.png)](https://user-images.githubusercontent.com/146040/193851215-86b8ad05-0c1a-431c-ad4b-5750997fd642.png) [![Editing mapping predicates via the configuration page](https://user-images.githubusercontent.com/146040/193854181-af8b85f2-1444-4882-a0af-d8123331f30c.png)](https://user-images.githubusercontent.com/146040/193854181-af8b85f2-1444-4882-a0af-d8123331f30c.png) ### REST API [](#rest-api) This extension provides REST API endpoints for getting and setting the RDF mappings for a Wikibase entity. For more information, refer to the [REST API documentation](docs/rest.md). Installation ------------ [](#installation) Platform requirements: - [PHP](https://www.php.net) 8.1 or later (tested up to 8.4) - [MediaWiki](https://www.mediawiki.org) 1.43 or later (tested up to 1.43) - [Wikibase](https://wikibase.consulting/what-is-wikibase/) 1.43 or later (tested up to 1.43) The recommended way to install Wikibase RDF is using [Composer](https://getcomposer.org) with [MediaWiki's built-in support for Composer](https://professional.wiki/en/articles/installing-mediawiki-extensions-with-composer). On the command line, go to your wiki's root directory. Then run these two commands: ``` COMPOSER=composer.local.json composer require --no-update professional-wiki/wikibase-rdf:~2.0 ``` ``` composer update professional-wiki/wikibase-rdf --no-dev -o ``` Then enable the extension by adding the following to the bottom of your wikis [LocalSettings.php](https://www.pro.wiki/help/mediawiki-localsettings-php-guide) file: ``` wfLoadExtension( 'WikibaseRDF' ); ``` You can verify the extension was enabled successfully by opening your wiki's Special:Version page in your browser. PHP Configuration ----------------- [](#php-configuration) Configuration can be changed via [LocalSettings.php](https://www.pro.wiki/help/mediawiki-localsettings-php-guide). ### Allowed predicates [](#allowed-predicates) List of allowed predicates. Variable: `$wgWikibaseRdfPredicates` Default: `[]` Example: ``` $wgWikibaseRdfPredicates = [ 'owl:sameAs', 'owl:SymmetricProperty', 'rdfs:subClassOf', 'rdfs:subPropertyOf', ]; ``` You can also configure what predicates are allowed via the `MediaWiki:MappingPredicates` page. Development ----------- [](#development) To ensure the dev dependencies get installed, have this in your `composer.local.json`: ``` { "require": { "vimeo/psalm": "^4", "phpstan/phpstan": "^1.4.9" }, "extra": { "merge-plugin": { "include": [ "extensions/WikibaseRDF/composer.json" ] } } } ``` ### Running tests and CI checks [](#running-tests-and-ci-checks) You can use the `Makefile` by running make commands in the `WikibaseRDF` directory. - `make ci`: Run everything - `make test`: Run all tests - `make cs`: Run all style checks and static analysis Alternatively, you can execute commands from the MediaWiki root directory: - PHPUnit: `php tests/phpunit/phpunit.php -c extensions/WikibaseRDF/` - Style checks: `vendor/bin/phpcs -p -s --standard=extensions/WikibaseRDF/phpcs.xml` - PHPStan: `vendor/bin/phpstan analyse --configuration=extensions/WikibaseRDF/phpstan.neon --memory-limit=2G` - Psalm: `php vendor/bin/psalm --config=extensions/WikibaseRDF/psalm.xml` Release notes ------------- [](#release-notes) ### Version 2.0.0 - 2025-07-07 [](#version-200---2025-07-07) - Raised minimum MediaWiki version to 1.43 - Raised minimum PHP version to 8.1 - Translation updates for system messages (thanks @translatewiki and its translator community) ### Version 1.1.0 - 2022-11-25 [](#version-110---2022-11-25) - Added notification about SPARQL store behavior that shows on first edit - Translation updates for system messages (thanks @translatewiki and its translator community) ### Version 1.0.0 - 2022-10-04 [](#version-100---2022-10-04) Initial release for Wikibase 1.37 with these features: - Ability to add mappings to Items and Properties via an on-page UI - Inclusion of mappings in the RDF output - Configurable relationships (predicates), including configuration UI on `MediaWiki:MappingPredicates` - API endpoint to retrieve or update the mappings for an Entity - API endpoint to retrieve all mappings defined on the wiki - TranslateWiki integration - Support for PHP 8.0 and 8.1 ### Health Score 46 — FairBetter than 93% of packages Maintenance61 Regular maintenance activity Popularity34 Limited adoption so far Community20 Small or concentrated contributor base Maturity58 Maturing project, gaining track record Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
