The Web Machine Learning Working Group invites implementations of the Web Neural Network API Candidate Recommendation Snapshot.

The Web Neural Network API is a low-level browser API that enables hardware acceleration of machine learning models, opening the way to high-performance privacy-preserving usage of computer vision, natural language processing and generation or speech processing improvements emerging from the recent advances in the field.

Comments are welcome via the GitHub issues by 1 October 2023.

The CSS Working Group invites implementations of an updated Candidate Recommendation Snapshot of CSS Display Module Level 3. This module describes how the CSS formatting box tree is generated from the document element tree and defines the display property that controls it.

The Accessible Rich Internet Applications Working Group has published a Proposed Recommendation of Accessible Rich Internet Applications (WAI-ARIA) 1.2. This specification provides an ontology of roles, states, and properties that define accessible user interface elements and can be used to improve the accessibility and interoperability of web content and applications. These semantics are designed to allow an author to properly convey user interface behaviors and structural information to assistive technologies in document-level markup. This version adds features new since WAI-ARIA 1.1 to improve interoperability with assistive technologies to form a more consistent accessibility model for [HTML] and [SVG2]. This specification complements both [HTML] and [SVG2].

This document is part of the WAI-ARIA suite described in the WAI-ARIA Overview.

Comments are welcome through 28 May 2023.

W3C announced today the W3C Workshop “Secure the Web Forward”, June 7-8 2023, Hosted by Microsoft Reactor, London, UK.

The Secure the Web Forward W3C Workshop brings together experts in standards and best practices needed to secure Web Applications, practitioners of Security Supply Chain in Open Source contexts, developer advocates with a focus on security and developers, designers and technologists with experience in adopting and deploying Web security standards and practices. We aim to develop a comprehensive picture and roadmap to address the challenges Web developers face in ensuring their applications are secure.

The scope includes:

• How to bring the “secure software supply chain” approach to the web development community.
• Guidance for different types of web developers who work at different levels of the stack.
• How to make emerging web application security standards and technologies easier to use and adopt by web developers.
• How can open source security focused efforts better support the web developer community?
• How can Open Source security review processes serve as inspiration for review of new web specifications?

The Program Committee is exploring how to make use of the venue’s remote participation capabilities and will update the workshop home page as these get settled. Attendance is free for all invited participants and is open to the public, whether or not W3C members.

For more information on the workshop, please see the workshop details and submission instructions. Position papers are due by April 24, 2023.

The EPUB 3 Working Group has just published the Working Group Note of EPUB Type to ARIA Role Authoring Guide 1.1. This document provides guidance for publishers looking to move from the use of the EPUB 3 epub:type attribute to ARIA roles for accessibility.

The epub:type attribute has evolved to aid publisher workflows. It has limited use enabling reading system behaviors outside of some core functionality of EPUB (identifying navigation elements and enhancing media overlay documents). Although it was hoped the attribute would also expose information to assistive technologies, in practice it does not. The primary purpose of the ARIA role attribute, on the other hand, is to expose information to assistive technologies. It is not to facilitate user agent behaviors. This guide addresses key authoring differences to be aware of when migrating to ARIA roles from the epub:type attribute, or when using both attributes together. The goal is to help publishers avoid the pitfalls of applying ARIA roles like they would epub:type semantics and breaking the reading experience for users of assistive technologies.

The CSS Working Group has published a First Public Working Draft of CSS Animations Level 2. This CSS module describes a way for authors to animate the values of CSS properties over time, using keyframes. The behavior of these keyframe animations can be controlled by specifying their duration, number of repeats, and repeating behavior.

The CSS Working Group has published a First Public Working Draft of Web Animations Level 2. This specification defines a model for synchronization and timing of changes to the presentation of a Web page. This specification also defines an application programming interface for interacting with this model and it is expected that further specifications will define declarative means for exposing these features.
