MathML Mathematical Markup Language (MathML) is an application of XML for representing mathematical symbols and formulae, aimed at integrating them into World Wide Web documents. It is a recommendation of the W3C math working group. The specification of version 1.01 of the format was released in July 1999 and version 2.0 appeared in February 2001. In October 2003, the second edition of MathML Version 2.0 was published as the final release by the W3C math working group. MathML was originally designed before the finalization of XML namespaces. As such, MathML markup is often not namespaced, and applications that deal with MathML, such as the Mozilla browsers, do not require a namespace. For applications that wish to namespace MathML, the recommended namespace URI is http://www.w3.org/1998/Math/MathML. MathML deals not only with the presentation but can optionally also include information about the meaning of formula components (the latter part of MathML is known as MathML-Content). Because the meaning of the equation is preserved separate from the presentation, how the content is communicated can be left up to the user. For example, web pages with MathML embedded in them can be viewed as normal web pages with many browsers but visually impaired users can also have the same MathML read to them through the use of screen readers (e.g. using the MathPlayer plugin for Internet Explorer). Another standard called OpenMath which has been designed (largely by the same people who devised MathML-Content) more specifically for storing formulae semantically can also be used to complement MathML
