Extension:ContentTranslation

The ContentTranslation extension is a tool that allows editors to translate an article from one language to another with the help of machine translation and other translation aids. See Content translation for background and additional information. The extension is being developed by the Wikimedia Language Engineering team.

Installation
The extension needs the content translation server (a.k.a. cxserver) up and running.

See Content_translation/Setup for setting up the content translation server.

Translations database
This extension has an optional dashboard feature, which allows translators to see all the translations across all languages. In a multilingual installation of this extension, for example in Wikimedia wikis, a central database is required to serve the dashboard feature. To create that database, see the sql/contentranslation.sql file in the extension source code; Content translation/Database has more details. Once database is created, set the $wgContentTranslationDatabase global configuration variable as the name of database:

Extension dependencies
ContentTranslation depends on the following extensions:


 * 1) ext-ULS>Special:MyLanguage/Extension:UniversalLanguageSelector|UniversalLanguageSelector is required.
 * 2) ext-GuidedTour>Special:MyLanguage/Extension:GuidedTour|GuidedTour is optional. If installed, it will be used to show an explanation about moving a page out of user space.
 * 3) ext-Echo>Special:MyLanguage/Extension:Echo|Echo is optional. If installed, it will be used for showing "congratulations" notifications after completing translation milestones.
 * 4) ext-Wikibase>Special:MyLanguage/Extension:Wikibase|Wikibase is optional. If installed and configured similarly to Wikipedia, it will be used for automatic addition of interlanguage links (as sitelinks).
 * 5) ext-EventLogging>Special:MyLanguage/Extension:EventLogging|EventLogging is optional. If installed, can be used to log publishing, errors, and other events.
 * 6) ext-BetaFeatures>Special:MyLanguage/Extension:BetaFeatures|BetaFeatures is optional. If installed, ContentTranslation will appear as a beta feature in the preferences.

Configuration variables
For the full list and defaults, see extension.json in the source repository.
 * ContentTranslationExperimentalFeatures: Not used at the moment. Was used in the past for testing experimental features.
 * ContentTranslationDomainCodeMapping: Used to map between non-standard language codes and actual domains. The default is the same as in Wikipedia codes and domains.
 * ContentTranslationRESTBase: Configuration of RESTBase URL and connection parameters. The defaults are for Wikipedia.
 * ContentTranslationDatabase: The name of the database in which the common tables for managing translations across wikis are stored. The default is null, which means that the default database is used.
 * ContentTranslationCluster: In a Wikipedia-like database configuration, the name of the cluster on which the database is hosted. The default is null, which means that the default cluster is used.
 * ContentTranslationEventLogging: Whether EventLogging is enabled. The default is false.
 * ContentTranslationHighMTCategory: A category to which pages that have a high level of machine translation are added upon publishing. The default is null.
 * ContentTranslationSiteTemplates: Templates for essential URLs. The defaults assume Wikipedia, so this variable must be configured differently for other sites. Where relevant, $1 is replaced by the language code, and $2 is replaced by the page title.
 * ContentTranslationTranslateInTarget: Whether to open Special:ContentTranslation in the target wiki when clicking the button in the entry point. The domain will be based on $wgContentTranslationSiteTemplates. The default is to open Special:ContentTranslation on the same wiki. (For Wikipedia this is set to true.)
 * ContentTranslationAsBetaFeature: Whether ContentTranslation is a beta feature.
 * ContentTranslationDefaultSourceLanguage: The code of the default source language shown in the language selector. The default is English (en), which is the most common source language for most language. In the English Wikipedia this is set to Spanish (es).
 * ContentTranslationTargetNamespace: The default target namespace for published articles. The default is Main.
 * ContentTranslationCampaigns: Campaigns that are available in the URL as valid values for the campaign parameter in the URL. This allows automatic enabling of the beta feature and event logging.
 * ContentTranslationBrowserBlacklist; Browser blacklist. Uses the same format as $.client.test.
 * ContentTranslationCXServerAuth: CXServer connection configuration.
 * ContentTranslationEnableSuggestions: Whether to use the suggestions tab and automatic suggestions. This needs the GapFinder API. This is false by default, but true in Wikipedia.
 * RecommendToolAPIURL: The URL for the GapFinder API, needed if ContentTranslationEnableSuggestions is true.
