Semantic Interlanguage Links (a.k.a. SIL) is a Semantic Mediawiki extension to create and manage interlanguage links.

This extension helps to create interlanguage links and provides queryable annotations that:

  • Can connect pages with similar content for different languages to be accessible via the sitelink navigation
  • Provides a interlanguagelink parser function to create cachable assignments
  • Provides a interlanguagelist parser function to format a list of available language links
  • Provides a annotatedlanguage parser function to return the language code of the current page
  • To set the page content language of an article
  • Integration with Special:Search to search By Language

This video demonstrates the functionality of the Semantic Interlanguage Links extension.



The recommended way to install Semantic Interlanguage Links is using Composer with MediaWiki's built-in support for Composer.

Note that the required extension Semantic MediaWiki must be installed first according to the installation instructions provided.

Step 1

Change to the base directory of your MediaWiki installation. If you do not have a "composer.local.json" file yet, create one and add the following content to it:

	"require": {
		"mediawiki/semantic-interlanguage-links": "~2.1"

If you already have a "composer.local.json" file add the following line to the end of the "require" section in your file:

"mediawiki/semantic-interlanguage-links": "~2.1"

Remember to add a comma to the end of the preceding line in this section.

Step 2

Run the following command in your shell:

php composer.phar update --no-dev

Note if you have Git installed on your system add the --prefer-source flag to the above command.

Step 3

Add the following line to the end of your "LocalSettings.php" file:

wfLoadExtension( 'SemanticInterlanguageLinks' );


The parser function {{interlanguagelink: ... }} provides an interface to declare multilingual content using semantic annotations.

{{interlanguagelink: language code | interlanguage reference }}, the first argument specifies the language code (e.g es, ja) of the content while the second argument contains an arbitrary reference (interlanguage reference) that describes content of similar nature (content that should be connected to each other) for different languages.
