After collecting a lot of information about math translation libraries we found a lot of overlapping effort. There are at least 3 major open source math Braille translation projects, each supporting multiple Braille math codes (there are over a dozen types of Braille math worldwide).
This raises many questions. Which open source library should screen readers like NVDA and Orca use for Braille display support? Should they just use liblouisxml, since they already use liblouis for translating ordinary text into Grade 2 contracted Braille? Liblouisxml currently supports MathML but not TeX, so how would TeX be supported? Since that is used in WikiMedia equation images, it seems important. And, perhaps proprietary screen readers can take advantage of some of these libraries as well.
There is potential collaboration here. If you’re interested in working on these problems or in these projects, please join the new free-math mailing list.
