2025 Accessibility Investigation

• [ ] (35%) Accessible Node or similar API

  • [ ] (10%) Initial spec language agreement of Accessible Node (DRI @cookiecrook)
    • https://github.com/WICG/aom/issues/197 and/or
    • https://github.com/WICG/aom/issues/203
    • [x] 5% RFC proposal https://github.com/web-platform-tests/rfcs/pull/226
    • [ ] 5% RFC agreement (#191) and spec language
  • [ ] (15%) Initial implementation of Accessible Node (behind runtime flag?) in WebKit, Chromium, Gecko
    • [x] (5%) First Implementation in Gecko #1929144 @jcsteh
    • [x] (5%) Second Implementation in WebKit #299508 @rahimabdi
    • [ ] (5%) Third Implementation Chromium #457793927(DRI @janewman)
  • [ ] (10%) Tree Walker investigation using Accessible Node
    • [x] (6%) Write basic tree walker tests (tentative) that purposefully avoid all known tree implementation differences (scroll areas, pseudo elements and other generated content, etc.) (Partial in @jcsteh's https://github.com/web-platform-tests/wpt/pull/55784/)
    • [ ] (4%) Author investigation tests for which parts of Node or Tree might be standardized in 2025 or later?
      • [ ] (2%) Purposefully write failing tests (tentative) that expose the areas where the internal accessibility tree differ between engines
      • [ ] (2%) File AOM or ARIA issues if it appears are some tree relationships that might be standardized as part of a 2025 Investigation

• [ ] (35%) Acacia AAM test exploration (DRI @spectranaut)

  • [x] (10%) functional in implementations/APIs
    • not calling out all combos, but as examples:
      • Mac AX API in WebKit, Chromium, Gecko
      • Linux GTK in Chromium, Gecko
      • Windows UIA in Chromium, Gecko
      • Others?
        • Window MSAA? in Chromium, Gecko
        • Window IA2? in Chromium, Gecko
  • [x] (10%) RFC consensus?
  • [ ] (10%) functional in WPT CI?
    • Everyone please review https://github.com/web-platform-tests/wpt/pull/53733
  • [ ] (5%) additional test writing?

• [ ] (30%) Miscellaneous

  • [ ] #41 (@jnurthen)

I fixed the percentages to realign with 100% after replanning changes. Open to adjustment of course, but at least the math should be right. Current progress at 30%. PR: https://github.com/web-platform-tests/wpt.fyi/pull/4492

GetAccessibilityProperties 15% + Acacia AAM 20% + Misc 10% (30(2/6)=10) = 45%
