### proposal title
|
|
|
|
|
|
Improve internationalization of math support
|
|
|
|
|
|
### Summary
|
|
|
|
|
|
We propose work on MathJax, the basis for mathoid and thus the MediaWiki Math extension, that will greatly improve their internationalization.

### project idea
|
|
|
|
|
|
Since v2.0, the MediaWiki Math extension uses MathJax for rendering (instead of a full texlive installation). While MathJax provides better internationalization out of the box (e.g., Unicode support), MathJax currently lacks more advanced internationalization features such as bi-directional layout and support for so-called "elementary math" layout. This limits how how mathematics can be authored and rendered on MediaWiki installations and Wikipedia in particular.
|
|
|
|
|
|
> For the problem you identified in the previous section, briefly describe your how you would like to address this problem.
|
|
|
|
|
|
We propose to implement two features in MathJax and its tool chain to enable better internationalization: support for bi-directional content and support for "elementary math". For bi-directional support, we plan to implement full support for RTL direction in MathML (MathJax's internal format). In addition, we will develop a suitable set of TeX macros for authoring bi-di content. As part of this, we will add support for complex Unicode graphemes in the TeX input as well as improved font support for non-western Unicode codepoints.
|
|
|
|
|
|
For "elementary math" support, we similarly plan to implement a pre-processor for the relevant parts of the MathML specification as well as a set of TeX macros for authoring.

### How will you know if you have met your goals?
|
|
|
|
|
|
We will follow MathJax's established development processes to implement the new features, in particular code review and automated testing. We will build on our existing contacts with WMF developers and the volunteers developing the MediaWiki Math Extension to ensure that the new features can be integrated into mathoid and the Math Extension. Finally, we will work with the Wikipedia community at large to ensure that our implementation helps solve the problems faced by the community in real life.

|
|
|
|
Doe not apply.

|
|
### Activities
|
|
|
|
|
|
The resources will provide developer time for the MathJax project, a joint venture of the American Mathematical Society and the Society for Industrial and Applied Mathematics to provide open-source technology for mathematics on the web.

### Community engagement plans
|
|
|
|
|
|
We have been in close contact with WMF developers and the volunteer developers of the MediaWiki Math Extension for several years. Both of these groups have offered to help with the interaction with the wider community.

Participants
|
|
|
|
|
|
The main grantee should be the American Mathematical Society as managing partner of the MathJax Consortium.
|
|
|
|
|
|
Its team consists of:
|
|
|
|
|
|
Davide Cervone is the creator and lead developer of MathJax. Davide has enabled math on the web since creating jsmath in 2004 and also works on WeBWorK.
|
|
|
|
|
|
Volker Sorge is a core developer for MathJax. He is also the creator and lead developer of the speech-rule-engine, a JavaScript-based accessibility solution for STEM content that began as (and still is) a component in Google ChromeVox.
|
|
|
|
|
|
Peter Krautzberger manages the MathJax project for AMS and SIAM. He also works as a developer on STEM publishing workflows to the web.
