I suggest readers of this group to have a look at the MathML protocol <http://www.w3.org/>: * The MathML group will contact the Unicode group for mathematical character improvements. This seems to relate to the attempts of pinning down mathematical characters in this group. * The MathML graphical features certainly relates to similar discussions in this group. (For example, I suggested they bring up the question of commutative diagrams, perhaps making 3D commutative diagrams.) * There is a LaTeX->MathML converter effort. * Some MathML features seems to relate to a topic discussed here, namely how to write mathematical formulas with more semantic information (eg. writing \connection, a name for the mathematical object, instead of \nabla, a name for the graphical rendering of a mathematical object). If those interested have a look at it, there may come up some other aspects. Hans Aberg * AMS member: Listing <http://www.ams.org/cml/> * Email: Hans Aberg <[log in to unmask]>
