W3C's Math Working Group has published an updated Working Draft for the
"Mathematical Markup Language (MathML) Version 3.0" specification.
MathML is an XML application for describing mathematical notation and
capturing both its structure and content. The goal of MathML is to
enable mathematics to be served, received, and processed on the World
Wide Web, just as HTML has enabled this functionality for text. MathML
can be used to encode both mathematical notation and mathematical
content. About thirty-five of the MathML tags describe abstract
notational structures, while another about one hundred and seventy
provide a way of unambiguously specifying the intended meaning of an
expression. Additional chapters discuss how the MathML content and
presentation elements interact, and how MathML renderers might be
implemented and should interact with browsers. Finally, this document
addresses the issue of special characters used for mathematics, their
handling in MathML, their presence in Unicode, and their relation to
fonts. While MathML is human-readable, in all but the simplest cases,
authors use equation editors, conversion programs, and other specialized
software tools to generate MathML. Several versions of such MathML
tools exist, and more, both freely available software and commercial
products, are under development. This specification of the markup
language MathML is intended primarily for a readership consisting of
those who will be developing or implementing renderers or editors using
it, or software that will communicate using MathML as a protocol for
input or output. It is not a User's Guide but rather a reference document. More See also the Math Working Group Roadmap: More Information
