Release of MathML v3 as a W3C Standard

Posted by Brian Kelly on 29 Oct 2010

On 21 October 2010 the W3C made an announcement about an “important standard for making mathematics on the Web more accessible and international, especially for early mathematics education“. The press release described how “MathML 3 is the third version of a standard supported in a wide variety of applications including Web pages, e-books, equation editors, publishing systems, screen readers (that read aloud the information on a page) and braille displays, ink input devices, e-learning and computational software.”

But what about support from browser vendors?  The press release went on to describe how “MathML 3 is part of W3C’s Open Web Platform, which includes HTML5, CSS, and SVG. Browser vendors will add MathML 3 support as they expand their support for HTML5. Firefox and Camino already support MathML 2 natively, and Safari/WebKit nightly builds continue to improve. Opera supports the MathML for CSS profile of MathML 3. Internet Explorer users can install a freely-available MathPlayer plug-in. In addition, JavaScript software such as MathJax enables MathML display in most browsers without native support.

Does it work? In order to investigate I installed the Firemath extension for FireFox and the MathPlayer plugin for Internet Explorer.  I then viewed the MathML Browser Test (Presentation Markup) page using FireFox (v 4.0), Chrome, Internet Explorer (v 8) and Opera (v 10.61). The results shown using Internet Explorer version 8 are shown below, with the first and second columns containing an image of how the markup has been rendered in TeXShop and FireFox with STIK Beta Fonts and the third column showing how the markup is rendered in the browser the user is using.

A quick glance at the display on all four browsers shows that the support seems pretty good [Note following a commented I received I have noticed that the page isn’t rendered in Chrome) – added 2 November 2010].  However it would take a  mathematician to ensure that the renderings of mathematical formula are acceptable.

It should also be noted that MathML 3 is part of HTML5. This means that embedding maths in Web documents should become easier, with direct import from HTML to mathematics software and vice versa.

In order to encourage takeup the W3C Math home page provides links to “A Gentle Introduction to MathML” and “MathML: Presenting and Capturing Mathematics for the Web” tutorials with “The MathML Handbook” available for purchase.

The W3C have provided a “MathML software list” together with a “MathML 3 Implementation Testing Results Summary” – which, it should be noted, has not not been updated since July 2010.

I think this announcement is of interest in the context of institutional planning for migration of document formats to richer and more open environments provided by HTML5 and associated standards such as MathML, CSS 3. etc.

Will we start to see documents containing MathML markup being uploaded to institutional repositories, I wonder? And should this format be preferred to PDFs for scientific papers containing mathematical markup?
