The EPUB 3 Working Group has published three Proposed Recommendations today for EPUB 3.3. This technology 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 three Proposed Recommendations are:

• The EPUB 3.3 specification defines the authoring requirements for EPUB Publications and represents the third major revision of the standard.
• The EPUB Reading Systems 3.3 specification defines the conformance requirements for EPUB 3 Reading Systems — the user agents that render EPUB Publications.
• The EPUB Accessibility 1.1 specifies content conformance requirements for verifying the accessibility of EPUB Publications. It also specifies accessibility metadata requirements for the discoverability of EPUB publications.

Comments are welcome through 15 May 2023.

The Web Applications Working Group has published a First Public Working Draft of Badging API. This specification defines an API that allows installed web applications to set an application badge, which is usually shown alongside the application’s icon on the device’s home screen or application dock.

The CSS Working Group has published CSS Box Model Module Level 3 as a W3C Recommendation. This specification describes the margin and padding properties, which create spacing in and around a CSS box.

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

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.

Comments are welcome via the GitHub issues by 30 May 2023.

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.
