W3C Invites Implementations of WebRTC 1.0 and Identity for WebRTC 1.0

The Web Real-Time Communications Working Group invites implementations of two Candidate Recommendations:

• WebRTC 1.0: Real-time Communication Between Browsers: this document defines a set of ECMAScript APIs in WebIDL to allow media to be sent to and received from another browser or device implementing the appropriate set of real-time protocols.
• Identity for WebRTC 1.0: this document defines a set of ECMAScript APIs in WebIDL to allow and application using WebRTC to assert an identity, and to mark media streams as only viewable by another identity.

First Public Working Draft: CSS Scrollbars Module Level 1

The CSS Working Group has published a First Public Working Draft of CSS Scrollbars Module Level 1. CSS Scrollbars standardizes the ability to color scrollbars introduced in 2000 by Windows IE 5.5. This is useful when building web applications which use color schemes very different from the appearance of default platform scrollbars.

CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc.

CSS Fonts Module Level 3 is now a W3C Recommendation

The CSS Working Group has published CSS Fonts Module Level 3 as a W3C Recommendation. This CSS Module describes how to specify fonts used in CSS, including Web Fonts downloaded on demand. It also describes how to access advanced typographic features in fonts, and how to control font loading. This specification is implemented in all modern browsers.

W3C Invites Implementations of Web Audio API

The Audio Working Group invites implementations of Web Audio API Candidate Recommendation. Web Audio is a high-level Web API for processing and synthesizing audio in web applications. The primary paradigm is of an audio routing graph, where a number of AudioNode objects are connected together to define the overall audio rendering. The actual processing will primarily take place in the underlying implementation, but using AudioWorklet, direct script processing and synthesis from JavaScript or Web Assembly is also supported.

Authorized Translation of WCAG 2.1 in Italian

Today the World Wide Web Consortium released the Authorized Italian Translation of Web Content Accessibility Guidelines (WCAG) 2.1, Linee guida per l’accessibilità dei contenuti Web (WCAG) 2.1, contributed by International Web Association (IWA). This translation of WCAG 2.1 coincides with the adoption of the EU Web Accessibility Directive and the related European Standard EN 301 549, which refers to WCAG 2.1. You may read W3C Blog post to learn more about the Adoption of WCAG 2.1 in Europe. Roberto Scano from IWA, who coordinated the translation, published a blog post in Italian.

The Web Accessibility Initiative (WAI) encourages the development of W3C Authorized Translations of WCAG 2.1 in all languages. Read about the Policy for W3C Authorized Translations.

Call for Review: Selectors Level 3 is a W3C Proposed Recommendation

The CSS Working Group has published a Proposed Recommendation of Selectors Level 3. Selectors are patterns that match against elements in a tree, and as such form one of several technologies that can be used to select nodes in an XML document. Selectors have been optimized for use with HTML and XML, and are designed to be usable in performance-critical code. This document describes the selectors that already exist in CSS1 [CSS1] and CSS2 [CSS21], and further introduces new selectors for CSS3 and other languages that may need them.

Comments are welcome through 12 October 2018.

First Public Working Drafts: JSON-LD 1.1 Syntax, JSON-LD 1.1 Processing Algorithms and API, and JSON-LD 1.1 Framing

The W3C JSON-LD Working Group has published three First Public Working Drafts today.

• The JSON-LD 1.1 Syntax document defines a JSON-based format to serialize Linked Data. The syntax is designed to easily integrate into deployed systems that already use JSON, and provides a smooth upgrade path from JSON to JSON-LD. It is primarily intended to be a way to use Linked Data in Web-based programming environments, to build interoperable Web services, and to store Linked Data in JSON-based storage engines. The 1.1 version of this specification will extend the existing JSON-LD 1.0 Recommendation, published in 2014.

• The JSON-LD 1.1 Processing Algorithms and API document defines a set of algorithms for programmatic transformations of JSON-LD documents. Restructuring data according to the defined transformations often dramatically simplifies its usage. Furthermore, this document proposes an Application Programming Interface (API) for developers implementing the specified algorithms. The 1.1 version of this specification will extend the existing JSON-LD Processing Algorithms and API Recommendation, published in 2014.

• The JSON-LD 1.1 Framing document defines an approach that allows developers to query by example and force a specific tree layout to a JSON-LD document.

All three documents are derived from Community Group Reports published by the JSON for Linking Data W3C Community Group.

The Working Group welcomes comments via the GitHub repository issues (see the respective documents’ headers for the reference of the repositories).
