MathDOM - Content MathML in Python

MathDOM is a set of Python 2.4 modules (using PyXML_ or lxml_, and pyparsing_) that import mathematical terms as a Content MathML_ DOM. It currently parses MathML and literal infix terms into a DOM document and writes out MathML and literal infix/prefix/postfix/Python terms. The DOM elements are enhanced by domain specific methods that make using the DOM a little easier. Implementations based on PyXML and lxml/libxml2 are available.

You can call it the shortest way between different term representations and a Content MathML DOM. Ever noticed the annoying differences between terms in different programming languages? Build your application around MathDOM and stop caring about the term representation that users prefer or that your machine can execute. If you need a different representation, add a converter, but don't change the model of your application. Literal terms are connected through an intermediate AST step that makes writing converters for SQL/Java/Lisp/your-favourite easy.
