  - UI Specification Schema CG
    - The UI Specification Schema Community Group will define a common, implementation-agnostic meta-model for specifying the design, layout, behaviour, and constraints of user interface elements. The goal is to enable designers, developers, and QA teams to describe any UI component — from buttons to complex composites — in a precise, machine-readable format that can be validated and consumed by tools across web, mobile, desktop, and embedded platforms.
  - Dynamic Configuration Management CG
    - The mission of this Community Group is to explore and define technologies, best practices, and tools for managing dynamic configuration data in the domains where dynamic updates and validation are primary concerns.
- co-chair
  - JSON-LD WG: 新任 Gregg Kellogg (IE)
