If you like the following, you probably want to read the attachment. Otherwise, you probably don't. It's pretty pie-in-the-sky, but it's a rational direction to go in, I think.

"The vision for formula objects is universality: all office documents recognize the same formula objects. Given the same formula object, text and presentation documents should render the formula correctly, and spreadsheet documents should perform the correct calculation. The user does not need to manage two separate articulations of the same concept: one for display and one for calculation. Cutting and pasting (or even linking) an equation from a context where it is rendered to a context where it is calculated should automatically produce the correct results."

This is an offshoot of the discussion last week/earlier this week with Leonard Mada regarding regression lines on charts and the desire to implement other regressions in something like S+/R. The only thing I didn't really like about that idea was the selection of a particular implementation language. So I started to investigate how far one might be able to run with just Content MathML and the OpenMath content dictionaries. Viola.

Thanks for listening,

Bryce
