I think we spoke at the Joint Meetings about some of your projects, a conversation I wasn't able to follow up on due to time constraints (though I still have your email on a Sage business card). Here are some things you may want to do with this; this sounds quite valuable. First, look at http://trac.sagemath.org/sage_trac/browser/sage/misc/mathml.py which is a (very old) implementation of some kind of MathML output from Sage thing. I have no idea if it is any good or works, given that there are no docstrings :) and there is also sage: search_def('mathml') misc/mathml.py:57:def mathml(x): rings/integer.pyx:1035: def _mathml_(self): rings/rational.pyx:705: def _mathml_(self): symbolic/constants.py:239:def unpickle_Constant(class_name, name, conversions, latex, mathml, domain): symbolic/constants.py:268: def __init__(self, name, conversions=None, latex=None, mathml="", symbolic/constants.py:414: def _mathml_(self): symbolic/expression.pyx:669: def _mathml_(self): so at least a tiny bit of support, but it's very rudimentary. Here's one doctest: sage: mathml(pi+2) MATHML version of the string pi + 2 For some history, some comments William made a few years ago. http://www.mail-archive.com/[email protected]/msg00234.html I suppose that when we switch to MathJax we could potentially do a Sage -> MathJax -> MathML conversion trip. Does jsmath support MathML? I don't think so. Also, unless this was you, which I don't think, others have asked about this. See for example http://ask.sagemath.org/question/527/parse-and-evaluate-mathml - so this is a great project. Finally, where to contribute? Amazingly, there isn't an open Trac ticket for this. I've opened http://trac.sagemath.org/sage_trac/ticket/13086 for this. All you have to do is acquire a Trac account (see http://trac.sagemath.org/sage_trac/ for instructions, this is not hard) and post code. Ideally, of course, this would be something created using our standard developer workflow (see http://www.sagemath.org/doc/developer/index.html) but I'm not sure exactly how you've put it there. I feel like this should go in sage/interfaces/mathml.py, and maybe the "old" stuff should too. See http://trac.sagemath.org/sage_trac/browser/sage/interfaces/r.py or other files in sage/interfaces, especially the def _sage_(self): methods. If some students helped, so much the better - we love having new contributors and helping students see that computation and math go together.
