This is the list of proposed Community and Business Groups. To express support for a
group, you must have a W3C account. Once a group has sufficient support
(5 supporters), W3C
announces its creation, lists it on the current groups page, and people
can join it to begin work.
Community Groups are proposed and run by the community. Although W3C
hosts these conversations, the groups do not necessarily represent the views of the W3C Membership or staff.
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.
The Meta-Layer Infrastructure Community Group will explore and advance protocols, design patterns, and shared standards for the interface layer of the Web—where people interact through browsers and overlays. Our goal is to support the emergence of a trusted, decentralized, civic infrastructure above Today’s Web, enabling contextual trust, coordination, and visible presence across communities and applications.
This group may publish Specifications.
Scope
This group will investigate and propose solutions in the following areas:
Overlay coexistence and spatial protocol zones: Guidance for how browser extensions, tooltips, and overlays can avoid collisions (e.g., multiple extensions competing for the lower right corner), and how to foster cooperative behaviors across interface-layer tools.
Contextual annotation and semantic overlays: Building on existing Web Annotation standards, we will explore how communities can layer interpretable, contextual meaning on top of existing content—including the use of shared ontologies, tagged trust signals, and localized interpretation layers.
Presence and trust signaling at the interface layer: How to represent people, groups, and values in a transparent and auditable way, including live annotations, endorsements, and role-aware overlays—without requiring centralized backends.
Interface-level AI alignment: Proposals for grounding, auditing, and co-governing AI tools that operate at the interface (e.g., summarizers, guides, fact-checkers), including how overlays can provide context, source-trails, and counterfactuals.
Digital artifact recognition and integrity: Defining how communities and systems might represent and verify digital artifacts (e.g., credentials, publications, declarations) at the interface layer using open standards—without presupposing any specific backend architecture.
Deliverables
A specification or design guide for overlay interoperability and spatial etiquette
Proposed extensions or usage conventions for Web Annotations and trust-layer metadata
Pattern libraries for presence-based interaction and integrity signaling
Draft interface standards for AI overlays and civic contextualization
Community dialogue around digital artifact integrity and use-case alignment
Participation
Open to standards developers, civic technologists, browser extension authors, Web annotation experts, trust & safety practitioners, and communities interested in building shared public infrastructure across the Web.
