Re: Evaluating Content MathML

You might want to look at GUI Kit for Mathematica.

Mathematica already contains necessary facilities for converting
expressions such as (x + 5*y) * 4^2 into content MathML so that you
could concentrate on writing your ontology. OOTH, within Mathematica,
you could skip the content MathML step entirely and just create the

I believe GUIKit is Java based. Also, there is something called a
"Super Widget Package" written by a Mathematica community member that
makes writing GUI Kit programs easier. However, I have never attempted
to make a GUI Kit program.
