  The   RDF Dataset Canonicalization and Hash Working Group   invites implementations of the   RDF Dataset Canonicalization   Candidate Recommendation Snapshot. RDF [ RDF11-CONCEPTS ] describes a graph-based data model for making claims about the world and provides the foundation for reasoning upon that graph of information. At times, it becomes necessary to compare the differences between sets of graphs, digitally sign them, or generate short identifiers for graphs via hashing algorithms. This document outlines an algorithm for normalizing   RDF datasets such that these operations can be performed.

  The   RDF Dataset Canonicalization and Hash Working Group   has published a Group Note of   RDF Dataset Canonicalization and Hash Working Group — Explainer and Use Cases.   This is a supporting document for the   RDF Dataset Canonicalization   specification, providing some extra explanation of the problem space and associated use cases.

  The Accessibility Guidelines Working Group ( AG WG ) published   Web Content Accessibility Guidelines (WCAG) 2.2   as a W3C Recommendation. WCAG and supporting documents explain how to make content more accessible to people with disabilities. For an introduction to WCAG, see the  WCAG 2 Overview . WCAG 2.2 adds 9 requirements (called success criteria) since WCAG 2.1. These success criteria improve accessibility for people with visual, physical, and cognitive disabilities. For example, they expand guidance for touch input. To learn more about WCAG 2.2, see   What's New in WCAG 2.2 .

  The  Web & Networks Interest Group  has published a first Draft Note of  Client-Edge-Cloud coordination Use Cases and Requirements . This document explores how the traditional client/server architecture used by Web applications could be improved by including edge computing resources, based on use cases and requirements and what new interoperable technologies would be needed to that end.

  W3C released today the   2023 diversity report . As part of our commitment and continued focus on diversity and inclusion, since 2018 we annually report on gender and geographic diversity at W3C. We would like W3C to be a model of supporting diversity. As an international organization, we can see the immense value we gain from having greater gender diversity, and expertise from across multiple countries and cultures. The diversity of the whole world needs to be reflected, as 60% of the world is now online and as more people continue to access and use the Web that we develop the standards of, here together at the Web Consortium. We believe that more diversity means better representation, which leads to better and more inclusive design. Indeed, more background, more use cases, more edge cases, lead to a better Web. More diversity also brings higher quality results. This year again, we are able to financially help cover  TPAC 2023  meeting travel costs for three perso...

  The   CSS Working Group   invites implementations of the   CSS View Transitions Module Level 1   Candidate Recommendation Snapshot. This module defines the View Transition API, along with associated properties and pseudo-elements, which allows developers to create animated visual transitions representing changes in the document state.  Comments are welcome via the  GitHub issues  by  5 December 2023 .

  The   Internationalization Working Group   has published a first Draft Note of   Catalan Gap Analysis . This document describes and prioritises gaps for the support of Catalan on the Web and in eBooks. In particular, it is concerned with text layout. It checks that needed features are supported in W3C specifications, in particular HTML and CSS and those relating to digital publications. It also checks whether the features have been implemented in browsers and ereaders.   This is a preliminary analysis .

  The Accessibility Guidelines Working Group ( AG WG ) and the WCAG2ICT Task Force has published  Guidance on Applying WCAG 2.2 to Non-Web Information and Communications Technologies (WCAG2ICT)   as a Group Draft Note. This document is a first draft update to the previous WCAG2ICT Note that provided guidance on applying WCAG 2.0 to non-web documents and software. This updated draft includes guidance for WCAG 2.1 success criteria and glossary terms. The group will add guidance for WCAG 2.2 success criteria in upcoming drafts. For an introduction, see the   WCAG2ICT Overview

  The   Web of Things Working Group   has just published three Proposed Recommendations for WoT. 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. The three Proposed Recommendations are: Web of Things (WoT) Architecture 1.1  describes the abstract architecture for the W3C Web of Things based on a set of requirements derived from use cases for multiple application domains. This specification describes a superset of the features defined in the WoT Architecture 1.0 specification. Web of Things (WoT) Thing Description 1.1  describes the metadata and interfaces of Things, where a Thing is an abstraction of a physical or virtual entity that provides interactions to and participates in the Web of Things. This specification ...

  The  Internationalization Working Group  has published a first Draft Note of  Korean Layout Gap Analysis . This document describes and prioritises gaps for the support of Korean language on the Web and in eBooks. In particular, it is concerned with text layout. It checks that needed features are supported in W3C specifications, in particular HTML and CSS and those relating to digital publications. It also checks whether the features have been implemented in browsers and ereaders.  This is a preliminary analysis .

  The  Web Applications Working Group  has published  Web Share API  as a W3C Recommendation. This specification defines an API for sharing text, links and other content to an arbitrary destination of the user’s choice. The available share targets are not specified here; they are provided by the user agent. They could, for example, be apps, websites or contacts.

  The   Web Applications Working Group   invites implementations of the following two updated Candidate Recommendation Snapshots: UI Events KeyboardEvent code Values  defines the values for the KeyboardEvent.code attribute, which is defined as part of the UI Events Specification [ UIEvents ]. The code value contains information about the key event that can be used to identify the physical key being pressed by the user. UI Events KeyboardEvent key Values  defines the  key attribute values  that must be used for  KeyboardEvent ‘s  key  attribute, which is defined as part of the UI Events Specification [ UIEvents ].

  The  EPUB 3 Working Group  has published  EPUB 3.3 ,  EPUB Reading Systems 3.3  and  EPUB Accessibility 1.1  as W3C Recommendations, as part of the  Digital Publishing activity . EPUB defines a distribution and interchange format for digital publications and documents. The EPUB format provides a means of representing, packaging, and encoding structured and semantically enhanced web content — including HTML, CSS, SVG, and other resources — for distribution in a single-file container. The content specification, which is what publishers, creators, or authors are really interested in, is now separate from the reading system specification that is of primary interest for implementers only. Editorial changes made the documents more readable. Accessibility of EPUB publications was an essential part of the group’s activity. As a result, the EPUB Accessibility specification has been updated and, for the first time in the history of EPUB, is now an in...
