Semantic Interlanguage Links

     

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

This extension creates interlanguage links and provides queryable annotations that can connect pages with similar content for different languages to be accessible via the [sitelink navigation][sitelink] by using the interlanguagelink parser function.

The following video demonstrates "How SIL works" without much user interaction or complex editing procedures.

Requirements

• PHP 5.3.2 or later
• MediaWiki 1.23 or later
• [Semantic MediaWiki][smw] 2.1 or later

Installation

The recommended way to install Semantic Interlanguage Links is by using [Composer][composer] with an entry in MediaWiki's composer.json.

json
{
	"require": {
		"mediawiki/semantic-interlanguage-links": "~1.1"
	}
}

1. From your MediaWiki installation directory, execute composer require mediawiki/semantic-interlanguage-links:~1.1
2. Navigate to _Special:Version_ on your wiki and verify that the package have been successfully installed.

Usage

The parser function {{interlanguagelink: language code | interlanguage reference }} provides in-text annotation support with the first argument being a language code (e.g es, ja) while the second argument contains an arbitrary reference (interlanguage reference) that describes similar content for different languages.

!sil

The parser function {{interlanguagelist: interlanguage reference | template }} can generate a customizable language target link list for the selected interlanguage reference to be available as wikitext inclusion using a template with the following parameters:

• target-link being the target link
• lang-code the language code
• lang-name representing the localized language name for the language code
• # contains the list position

SIL expects that only one specific language is asssigned to a content page and if multiple assignments are made an error notice will be displayed.

Example

Create interlanguage links

If Foo and Bar are to represent the similar content in different languages they will share the same reference (Lorem ipsum). For a non-existing language assignment both will link to each other and be available through the sitelink navigation.

text
Page: Foo

Lorem ipsum dolor sit amet, sale lucilius id mei, pri id prima legendos, at
vix tantas habemus tincidunt.

{{interlanguagelink:la|Lorem ipsum}}

text
Page:Bar

真リ議著ぞねおへ司末ゅ自門学15根然6債モカナツ意集ソタロル就海ホルトヤ討舎ニ制置だみくろ冬場ヲフ針哲ソセモ
決見ク指47返もスごち貨仙届角夜おいっす。

{{interlanguagelink:ja|Lorem ipsum}}

List languages

Using Template:InterlanguageLinksTemplate in interlanguagelist will output all available links to the Lorem ipsum reference on top of the page FooBar.

text
Template:InterlanguageLinksTemplate

<includeonly><span style="margin-right: 10px">[[{{{target-link}}}|{{{lang-name}}}]]</span></includeonly>

text
Page:FooBar

{{interlanguagelist:Lorem ipsum|InterlanguageLinksTemplate}}

Other features

• The page content language is preset with the language annotated by INTERLANGUAGELINK together with an auto-updated sitelink navigation for pages that point to the same interlanguage reference.
• The following predefined properties Page content language, Interlanguage reference, Interwiki language, Interwiki reference, and Has interlanguage link can be used to create customized #ask queries (e.g Has interlanguage link.Page content language).
• SIL provides a by Language Special:Search filtering option to match interlanguage property annotations for pre-selected pages. If the by Language profile (or the advanced profile) is used together with a specific language filter then any pre-selected article (provided by the SearchEngine) that does not match the language will be excluded from the result list. It may be necessary to broaden the limit before a match can be found because SIL does only compare languages against pre-selected results (it does not search by itself).
• If a category page contains a Page content language annotation, SIL will filter and display only pages that match that content language. In cases where no language has been assigned (or filtering has been disabled), the category page will display all pages without changes or filtering.
• In cases where an interwiki language link (e.g [[en:Foo]]) is added to a page (representing a non-local link, see also [wgInterwikiMagic][iwlm] or [wgExtraInterlanguageLinkPrefixes][iwlp]), SIL will create an additional Has interlanguage link entry (internally being identified by something like Foo#iwl.en). The interwiki information will not be available for any language filter (search, category).

Configuration

• $GLOBALS['egSILCacheType'] = CACHE_ANYTHING; is being set to be the default value to improve query lookups during each page view with cache invalidation being carried out during any delete, change or move action.
• $GLOBALS['wgHideInterlanguageLinks'] is enabled (set to true), no sitelinks or annotations are created (in order to correspond to the MW default behaviour for interwiki links)
