Expert Accessibility Handlers Mission Statement, Draft 5
Generalized content markup (such as HTML) is complimented by markup specifications that facilitate more semantically precise content markup. Examples of specialized, semantically precise markup include MathML  and MusicXML . Assistive technology (AT) typically handles generalized content markup, but does not know about specialized markup. Because of this, users of AT are unable to access or navigate specialized markup effectively.
The Open A11y Expert Handlers SIG is exploring a standardized plug-in mechanism to AT software. The goal of this plug-in standard is to allow AT software to take advantage of expert software that understands specialized markup. This plug-in standard will allow the expert software to provide enhanced, semantically rich access to specialized markup so that the AT can properly render (visually, aurally, and/or tactilly) and help users navigate the semantic meaning encoded in the specialized markup.
NS: any feedback?
JS: reread -- very happy
Shawn: tactilly or tactilely?
conflict of spelling -- need to check OED
PB: Mirriam-Webster has it between 2 ells
JS: point with confidence -- MusicML smooshy, no real standards, just competing standards
NS: no real semantics; doesn't meet needs
GJR: SVG plus ARIA?
NS: CellML -- markup language to describe biological bio-chemical and chemichal markup; modeling cellular behavior -- too abstract?
NS: chose music because simpler
V: people will understand musical markup
NS: wikipedia -- MusicML supported by 80 applications
V: let's leave it
NS: does have some legitimacy
GJR: Vladmir's right musical vocabulary standardized, handy for breaking down items into component parts that people can understand (bar, measure, note, etc.)
PROPOSED: make this our mission statement
RESOLVED: this will be our mission statement
