Content translation version 2 (CX2) is a major refactoring and architectural update of Content Translation (CX). The goal is to provide a solid and reliable translation tool that is aligned with the Wikimedia standards in technology and design, and provides a great way to contribute for newcomers. Version 2 uses the Visual Editor editing surface, uses a OOUI based front end, and follows the Wikimedia design guidelines. In addition, learnings from existing and new research on the experience of new editors will be used to identify improvements to make translation a great way to start contributing to Wikipedia.
The plan is to gradually replace version 1 with version 2 in several stages. A backwards compatibility plan will make sure that content created by users during the transition period won't be affected.
- 1 Try the new version
- 2 Features
- 3 Status Updates
- 4 Plans
Try the new version
The new version is in an early stage, and it is still in active development. Please, use it to translate articles and report feedback. We love to hear what works for you, and what still needs improvement.
The new version is available in production on Wikipedia, and can be enabled from the translation dashboard by clicking on the "Try the new version" link on the "Need help translating?" section. This will activate the new version for any new translation you start next.
Using version 2 on production will create content in real wikis when you publish your translation, so it is not suited for experiments that don't create a quality translation as a result. For more experimental testing, you can try the new feature in our testing servers. They are a separate wiki (you need to create a new user account since the log-in service is not integrated with Wikimedia projects). Although the content you translate in the test servers comes from real Wikipedias, the published content will be only created in the test server. This allows to experiment without interfering with the work done in those projects.
We are interested in hearing how well the new version works for both new and existing users of Content Translation. If you are providing specific feedback about version 2, make sure to mention it refers to CX2. Otherwise, it may be harder to identify the issue. You can use the CX2 discussion page for specific feedback on CX2, and report issues in Phabricator.
Track articles created
A dashboard shows the translations published with the new version and the number of users publishing these. In addition, articles published with the new version are marked with the #contenttranslation-v2 edit tag to facilitate finding them (e.g., using Recent Changes) and evaluate the quality of the content.
The new version will include a more powerful editing surface, which will bring new possibilities that were repeatedly requested by translators using the tool. However, other features form version 1 won't be initially available with the new version.
A general CX2 roadmap describes the planned interventions in more detail. The main areas of intervention are:
- Align with the Wikimedia standards in technology and design
- Visual Editor's editing surface with more editing tools to insert and edit templates, tables, multimedia, categories, etc.
- Reliable undo/redo support.
- UI revamp based on UI Standardisation initiative and OOUI components
- A great way to contribute for newcomers
- Machine translation support for Template params, reference texts and practically all kind of elements in screen. In version 1, machine translation was limited to paragraphs alone.
- Better support for References and Templates
- Ability to add and remove categories
- Solid and reliable
- Fixing lots of bugs that was too difficult to handle with previous version
Missing features from the current version
The features listed above are possible with the new technology architecture. However, in order to be able to deliver those improvements soon, we have to limit the efforts of rewriting all the existing tools CX1 has. Thus, some of the existing tools won't be available in CX2 initially. We selected those based on our observations of current use, the value they provide in version 1 and their complexity, but we are looking for your feedback during this process.
These are the tools currently in CX1 that will be missing initially for CX2:
- Custom template translation editor. CX1 added support for a side-by-side editor of templates that allowed translators to map their parameters. The initial implementation allowed to evaluate a promising concept but it was far from being complete, and rewriting this for CX2 will require significant effort. Initially, the standard template editor dialog provided by Visual Editor will be available in CX2 instead. Although it is not optimized for transferring information across languages, it provides basic support for editing all parameters of a template in the translation.
- Dictionaries. CX1 had experimental support for dictionary information lookup for a few language pairs. Dictionaries are a very relevant tool for translators, and we'll keep track the progress of Wikimedia projects in this area that will enable their integration in the future. However, providing support for CX2 makes more sense when there is a clear plan to integrate more dictionaries.
- Progress indicator in the editor. A progress bar showed in CX1 how much of the article was translated and how much was missing. This information will be still visible from the dashboard, but not while editing the article. Based on our observations from users, having it on the editor was not providing much value.
- Announcements of new machine translation services. The automatic translation card became highlighted when a new machine translation service was made available for the current language. This was especially useful in the initial staged of the tool where new services were added regularly. We can reconsider this feature once the migration to version 2 is completed and we plan to integrate new machine translation services in the future.
- Measurements for performance improvements in the access to external translation services.
- More reliable template processing to avoid issues with templates to block paragraphs to be added to the translation.
- Better control of content quality by adding to a tracking category published translations with unreviewed contents ( you can check the tracking category list on any language for the category with the code "cx-unreviewed-translation-category").
- Improved support for links by correcting a styling regression.
- Improved performance by prefetching requests to translation services in advance to deliver results immediately when users add a new paragraph, caching of API requests and an optimization of the caching system.
- More reliable saving process by retrying with an increased timeout after initial failure.
- More solid approach to divide the content into sections for the tool to handle, and preventing errors when adding sections to the translation.
- Improved support for inserting media, preventing the media dialog to block the article.
- Better support for references solving issues when editing references and displaying them.
- Improved control for excessive unmodified content by excluding types of content where the warning is not relevant in order to prevent false positives.
- Better support for red links, generating as red links only for the missing articles the user confirmed, and avoid rendering them as regular links in the source document.
- Better guidance by delaying content warnings only while the user is editing but showing previous warnings immediately when a translation is resumed.
- Improved alignment on RTL languages and a cleaner source article by avoiding noise characters showing from Visual Editor elements.
- More solid control of anonymous access by gracefully handling access errors.
- More reliable saving and recovering process to persist the contents when user switches between translation services, and avoid moving translations to in-progress when there are no further changes since they were published.
- Better guidance by communicating when templates could not be adapted.
- Better mapping references across languages by using Citoid metadata when mapping template parameters, avoiding issues with empty references and partially adapted ones.
- More effective integration with translation services by sending a more compact version of the content HTML to prevent exceeding the translation limits, improving efficiency and security. A regression in this area was also fixed.
- Facilitate the access to the new version by creating an outreach campaign link to be used in interactions with Wikipedia communities.
- Instrumentation improvements to better measure the issues translators experience.
- More reliable application of machine translation by avoiding quick manual modifications to be counted as machine translation, improving support for quote templates by avoiding blank text blocks to be sent for translation, avoid the adaptation of transclusion fragments, improved logging for Apertium, and better handling of templates and link attributes.
- More reliable visual alignment of paragraphs between original and translated content.
- Basic control for too much unmodified content warning, showing a warning at the paragraph level when machine translation has not been edited enough.
- Basic control to prevent publishing translation with very little modifications in the whole document showing an error.
- More reliable handling of failing Machine Translation services.
- Improved behaviour for "undo" when marking links as missing, and avoiding interference with saving.
- A #contenttranslation-v2 tag is added to published articles with version 2 to facilitate analytics. The usual #contenttranslation tag still applies to articles published with any version.
- Improvements in the issue communication system to support general issues that are not attached to a specific paragraph, and code refactoring to reduce duplications with the progress tracking system.
- More reliable application of machine translation to gracefully handle the failure of translation services, its application to references by avoiding repeated cite tags and repeated reference contents, a more reliable integration with Apertium.
- Communication of session expiration in the translation dashboard.
- Dashboard to show the translations published with the new version and the number of users publishing these.
- Support for switching between version 1 and 2 to allow users to test the new version, and provide access to information about the new version.
- Graphs for measuring the number of translators and articles published with the new version.
- Optimization to reduce the amount of data required to adapt templates improving the time to save contents, and better visual display of templates.
- Improved support for templates avoiding infoboxes to be missing on source articles, better support for coordinate templates avoiding these to break the visual alignment of paragraphs, and support for adding the list of references without errors.
- More reliable saving process avoiding blanked sections to remain unsaved.
- Improved visual alignment of paragraphs to avoid new templates added to the document to break it.
- Warning for too much unmodified content per paragraph to prevent machine translation misuse.
- Improved template translation by avoiding the mapping of parameters that do not exist in the target language.
- Support for videos, and inline images.

- More reliable application of initial translations by avoiding to leave the paragraph unusable when Machine Translation fails and when switching to not use machine translation.
- Improved issue communication system by allowing to mark issues as resolved for the current session, showing information about issues when they are relevant, and more clear message when there is too much unmodified machine translation.
- More reliable processing of the content to avoid some images not being displayed in the source article, bullet points to be skipped, wide images overflowing their column , and stub templates to avoid displaying them.
- Better support for content persistency when using the browser back button.
- Adjusted look for link information to improve consistency with Visual Editor and avoid code duplication.
- Support for keyboard navigation across paragraphs in the translation.

- Notifications for the deletion of old translation drafts, configurable period for deleting old drafts automatically and initial runs of the script to support backwards compatibility.
- Adjustments in the dialog layout used to edit complex content to preserve the document metaphor, enabling the use of the tools column.
- More reliable loading of articles avoiding instances of "page not found" error for existing articles.
- Better support to transfer content to the translation, including references , templates, links pointing to the same target, and avoiding errors when adding new paragraphs.
- Improved auto-save to better deal with sections that were added while the saving process was running.
- More precise timestamps for translations to prevent discrepancies due to local timezone differences.
- Linking automatically corresponding versions in other languages through Wikidata when the article is published.
- Refactoring of styles to better anticipate the effect of changes in the styling code and better align to Wikimedia standards.

- Layout adjustments to customize the editing toolbar, the sticky headers and how both fit together.
- Frequently requested features from VE are now available in CX2 with the new editing surface such as copy&paste links, edit link labels, reliable undo/redo, insert new templates, and converting wiki-syntax.
- Clean-up of the source article to remove irrelevant sections for the translation such as hat notes, metadata or links to sister projects.
- The version used remains persistent as part of each translation to support backwards compatibility, and as users navigate between the dashboard and the editor to facilitate testing.
- A basic side-by-side editor that would allow users to do a very manual translation. Many regressions after integrating the Visual Editor editing surface have been solved.
- Content persistency. The editor allows loading articles, automatic saving, and basic restoring of translations.
- Work with source and translation next to each other: add content paragraph by paragraph to the translation and keep paragraphs aligned.
- Layout reorganisation to align with the style guide.
- Improved testability. CX2 Test servers working again, and plans to support backwards compatibility.
Content Translation was developed iteratively for last 2+ years. During that time, the focus was to evaluate the core ideas on how to improve the translation experience for Wikipedia editors. The architecture was a flexible one where modules can be plugged and try these concepts. This allowed to move fast, but the approach and cut corners affected the code organisation, maintainability and reliability of the tool. The proposed refactoring and architectural update will contribute to provide a tool solid and reliable translation tool that is aligned with the Wikimedia standards in technology and design.
At the end of this intervention we want Content Translation to be a tool that:
- Is aligned with the Wikimedia standards in technology and design. Uses the editing surface technology of Visual Editor (VE), and follows the Design style guide principles.
- Is a great way to contribute for newcomers. The tool provides a quick and easy way for new editors to start contributing. Even if the tool does not support dealing with complex content or situations, it always provides a clear path forward for new editors.
- Is solid and reliable. The tool is reliable enough to go out of beta for at least one community.
The way to get there is detailed in different plans below.
Starting in February 2018, the CX2 roadmap defines the incremental stages to complete the development of the tool.
A rough plan is to enable version 2 in smaller wikis or subset of wikis to do QA and gradually rollout to more wikis. The list of representative wikis can be useful to identify candidates.
Backwards compatibility plan
Versions 1 and 2 will coexist during a transition period. Given that the translations each version produce are not expected to be compatible, the following steps are considered to avoid issues related to breaking backwards compatibility:
- Translations started with one version of the editor will be alway opened with the same version, regardless of which is the current default editor. That is, when version 2 is the default, old translations started with the version1 will still be opened with version 1.
- Once version 2 is considered the stable default, creating new translations with older versions will be prevented. That is, version 1 will not be available to create new translations, but it will be still available to edit the old ones.
- With a process in place to automatically discard translations after one year, version 1 could be safely removed after such period pases since no new articles can be started with it.
