Portable Network Graphics (PNG) Specification (Third Edition)

This document describes PNG (Portable Network Graphics), an extensible file format for the lossless, portable, well-compressed storage of static and animated raster images. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-color, greyscale, and truecolor images are supported, plus an optional alpha channel. Sample depths range from 1 to 16 bits.

Digital Publishing WAI-ARIA Module 1.1

Enabling users of assistive technologies to find their way through web content requires embedding semantic metadata about web document structural divisions. This is particularly important for structural divisions of long-form documents and goes along with embedding semantic metadata about web-application widgets and behaviors for assistive technologies. This specification defines a set of WAI-ARIA roles that are specific to helping users of assistive technologies navigate through such long-form documents.

Verifiable Credentials Data Model v2.0

A verifiable credential is a specific way to express a set of claims made by an issuer, such as a driver's license or an education certificate. This specification describes the extensible data model for verifiable credentials, how they can be secured from tampering, and a three-party ecosystem for the exchange of these credentials that is composed of issuers, holders, and verifiers. This document also covers a variety of security, privacy, internationalization, and accessibility considerations for ecosystems that use the technologies described in this specification.

Web of Things (WoT) Architecture 1.1

The W3C Web of Things (WoT) enables interoperability across IoT platforms and application domains. The goal of the WoT is to preserve and complement existing IoT standards and solutions. The W3C WoT architecture is designed to describe what exists, and only prescribes new mechanisms when necessary.

Web Content Accessibility Guidelines (WCAG) 2.2

Web Content Accessibility Guidelines (WCAG) 2.2 covers a wide range of recommendations for making web content more accessible. Following these guidelines will make content more accessible to a wider range of people with disabilities, including accommodations for blindness and low vision, deafness and hearing loss, limited movement, speech disabilities, photosensitivity, and combinations of these, and some accommodation for learning disabilities and cognitive limitations; but will not address every user need for people with these disabilities. These guidelines address accessibility of web content on any kind of device (including desktops, laptops, kiosks, and mobile devices). Following these guidelines will also often make web content more usable to users in general.
