The Web Applications Working Group has published a Working Draft of Selection API. This document is a preliminary draft of a specification for the Selection API and selection related functionality. It replaces a couple of old sections of the HTML specification, the selection part of the old DOM Range specification.
The RDF Data Shapes Working Group has published a Working Draft of Shapes Constraint Language (SHACL). SHACL (Shapes Constraint Language) is a language for describing and constraining the contents of RDF graphs. SHACL groups these descriptions and constraints into “shapes”, which specify conditions that apply at a given RDF node. Shapes provide a high-level vocabulary to identify predicates and their associated cardinalities, datatypes and other constraints. Additional constraints can be associated with shapes using SPARQL and similar extension languages. These extension languages can also be used to define new high-level vocabulary terms. SHACL shapes can be used to communicate information about data structures associated with some process or interface, generate or validate data, or drive user interfaces. This document defines the SHACL language and its underlying semantics.
The Web Application Security Working Group has published Candidate Recommendations for two documents that help Web authors and users toward secure, authenticated browsing:
- Upgrade Insecure Requests defines a mechanism which allows authors to instruct a user agent to upgrade a priori insecure resource requests to secure transport before fetching them.
- Mixed Content describes how a user agent should handle fetching of content over unencrypted or unauthenticated connections in the context of an encrypted and authenticated document.
The HTML Working Group has published a Proposed Recommendation of W3C DOM4. DOM defines a platform-neutral model for events and node trees. DOM4 adds Mutation Observers as a replacement for Mutation Events. Comments are welcome through 03 November.
The Web Applications Working Group has published a Working Draft of Shadow DOM. This specification describes a method of combining multiple DOM trees into one hierarchy and how these trees interact with each other within a document, thus enabling better composition of the DOM.
The HTML Working Group has published a Group Note of A transcript extension for HTML. This document describes an extension to HTML which explicitly identifies a transcript linked to a media object such as audio or video. It was created to meet requirements for transcriptions that are described in the Media Accessibility User Requirements (MAUR).
Building on the successful results of the first W3Cx HTML5 MOOC (Massive Open Online Course) course, W3C announced today that it will strengthen its online course offerings on edX with two more HTML5 courses and an XSeries Program dedicated to HTML5 at an intermediate level. HTML5 Part 1 is currently open for enrollment and begins on 5 October. HTML5 Part 2 will start on December 1. This pairing will enable participants to earn an XSeries Program Certificate from edX and W3Cx. Read the full press release.
The Web Performance Working Group has published a Working Draft of Frame Timing, which now uses a slow-only frames strategy. This specification defines an interface for web applications to access runtime performance information of the browser event loop, enabling them to identify and fix issues that cause delayed rendering, processing of input, and other critical work necessary to deliver a smooth and responsive user experience.
The HTML Working Group has published a Proposed Recommendation of HTML Canvas 2D Context. This specification defines the 2D Context for the HTML canvas element. The 2D Context provides objects, methods, and properties to draw and manipulate graphics on a canvas drawing surface. Comments are welcome through 21 October.
The Authoring Tool Accessibility Guidelines Working Group has published a W3C Recommendation of Authoring Tool Accessibility Guidelines (ATAG) 2.0. ATAG 2.0 provides guidelines for designing web content authoring tools that are both more accessible to authors with disabilities; and are designed to enable, support, and promote the production of more accessible web content by all authors. Implementing ATAG 2.0 has been published as a Working Group Note.
