+# MDN content project: ARIA roles reference docs
+
+This RFC proposes that we work on completing the [ARIA role reference docs](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles)
+available on MDN. We did quite a bit of work on this in the past, including
+having it as a major workstream at a past [Accessibility Hack on MDN event](https://hacks.mozilla.org/2018/10/hack-on-mdn-better-accessibility-for-mdn-web-docs/),
+but we still never got around to completing the docs.
+
+## Problem statement
+
+ARIA roles are an important part of the [WAI-ARIA](https://w3c.github.io/aria/)
+technology standard — they allow us to provide semantics where semantics are
+lacking, for the benefit of AT and AT-users. Unfortunately many roles are a bit
+obscure in their use, especially across different browser and screenreader
+combinations, and a lot of information on this topic is spread far and wide
+across the Web. It would be great to provide a deep and complete resource on
+this in one place.
+
+## Priority assessment
+
+This table checks this project against the [OWD prioritization criteria](https://github.com/openwebdocs/project/blob/main/steering-committee/prioritization-criteria.md).
+
+* **Effort**: Medium/High: Each page (60) is fairly large and may require some
+  research.
+* **Dependencies**: Need to find accessibility experts to help.
+* **Community enablement**: Yes. Each page is a self-contained task.
+* **Momentum**: Low/Medium. The tech itself is fairly stable, but a11y is
+  something we want to push.
+* **Enabling learners**: Not really. The MDN Learn section contains ARIA basics
+  already.
+* **Enabling professionals**: Yes.
+* **Underrepresented topics / Ethical web**: Yes. We want to push forward the
+  importance of a11y and make it easier to action.
+* **Operational necessities**: In a way, yes. Without a11y, certain groups
+  cannot use the web.
+* **Addressing the needs of the web industry**: Accessibility not seen as a
+  major pain point in Web DNA, but is that just because people don't understand
+  it?
+
+## Proposed solutions
+
+We need to write those pages.
+
+## Task list
+
+- Write out list of which roles pages are not written yet, and which ones are
+  incomplete/need improvement.
+- Make sure we agree on a template to base each page on — what does each page
+  need?
+- Write an issue for each page, and try to enlist the help of a11y experts to
+  write recommendations for the use cases/potential examples for each role,
+  plus links to anything that would help people get started.
+- Contact folks in the a11y community who might be willing to help write such
+  pages. Get them working on pages.
+- Create a spreadsheet to track progress on each page.
