Interesting. I tried many times to convince John Cannon to open source Magma, and always failed. In some ways, Sage is my final attempt to convince Magma to open source. So far unfortunately it is failed completely to achieve that, and I fear it never will, because too many egos are involved (unlike Sun, which is probably more about the bottom line). > > I was also pretty soundly criticized by someone else at the Wiris booth for > > (1) > > not using OpenMath/MathML for communication between different components > > of Sage, and (2) for not having an OpenMath output / input format for every > > Sage object.

Sure, start another thread.
