W3C
The World Wide Web Consortium, an international standards organization responsible for developing and promoting core web technology specifications including HTML and CSS. Its membership comprises major technology companies and research institutions.
Core Facts
WCAG (Web Content Accessibility Guidelines) is developed by W3C; the current mainstream version is WCAG 2.1, with three compliance levels: A, AA, and AAA.
WebRTC was open-sourced by Google in 2011 and was subsequently standardized by W3C and IETF.
WebGPU is a W3C-standardized browser graphics and compute API that was officially released in Chrome in 2023, designed to replace WebGL.

ARIA is an attribute specification developed by the W3C to describe element semantics and states to assistive technologies such as screen readers, for example role='dialog', aria-label, etc.
Calling the camera in the browser centrally relies on the MediaDevices.getUserMedia() API specified by the W3C, which requests camera and microphone permissions and returns a media stream.
FIDO2 is an industry standard jointly developed by the FIDO Alliance and W3C, and WebAuthn is the API specification within it targeting browsers and web applications.
WCAG is an international web content accessibility standard developed by the W3C, with three compliance levels—A, AA, and AAA—and mainstream versions 2.1 and 2.2.
ARIA Live Region is a mechanism in the W3C accessibility specification for notifying users of dynamic content; DOM regions marked as aria-live are monitored by screen readers, which automatically read out updated content.
W3C's Verifiable Credentials (VC) and Decentralized Identifier (DID) specifications, as well as the OpenID Foundation's GNAP protocol, are all attempting to make authorization boundaries machine-readable claims that can be independently verified by third parties.
Verifiable Credentials (VC) were formally standardized by W3C in 2022; their core concept is the separation of issuer, holder, and verifier, with credential content guaranteed to be tamper-proof via cryptographic signatures.
The W3C has proposed the research direction of 'Data Provenance,' which attaches verifiable source metadata to content.
OWL (Web Ontology Language), recommended by the W3C, is a common standardized form for expressing ontologies.
WebRTC is standardized by W3C and IETF, allowing browsers to establish direct audio, video, or data channels between each other without the need for an intermediate server to relay data.
