proposed ARIA role for math [DRAFT 1] Rationale ARIA 1.0 is intended as a solution for today's problems, as well as providing a means of supporting newer, more mature and/or accessible options for today's technology. MathML has been a W3C technical recommendation since 1998/1999 [1]; it is time -- and well within PF's purview -- to address this by introducing a specific role="math" into ARIA 1.0 therefore, i formally propose the following: <proposed cite="def-role-math"> Role: math Definition: contains a string of mathematics (expressed as ASCII or "rich" text, such as TeX), an image of a mathematical formula, or other such embedded content which is most accessibly expressed using MathML; this role enables a plug-in mechanism to provide compliant MathML, as well as enabling support for MathML in "mainstream" user agents. </proposed> i think we've waited long enough for "robust" and "mainstream" MathML support -- i know that my definition isn't the best, but between neil, raman, jason, janina, kenny, aaron, michael, marc and jon (and anyone else who might care to join in), a more "proper" definition could be quickly honed for inclusion in ARIA 1.0, as well as laying the ground work for an abstracted "formula" or "equation" or some such abstracted meta-role, if, indeed, one can be found. today's issue is enabling the use of existing technologies, and MathML is first amongst equals in that regard neil advanced a convincing argument for such a role, and his post was enthusiastically endorsed by others, including some who'd like to use MathML in their XML backplane and/or educational environments; it also received an immediate positive reaction from an implementor, which shows that if we define it it will be supported; moreover, what is at stake is enabling the widespread implementation and use of MathML, which fits the profile of the educational grant under which work on ARIA has been partially funded [2] it is an issue that should be brought to conclusion now, rather than delayed for the next iteration of ARIA -- the technologies and the possibilities exist, and therefore i believe that addition of a math role is important enough to warrant it being added to ARIA now, even if bug or issues need to be logged with the maintainers of IAccessible and AT-SPI -- and from what RichS reported, MSAA's ROLE_EQUATION could serve a dual use gregory.
