The RDF Dataset Canonicalization and Hash Working Group has published a First Public Working Draft of RDF Dataset Canonicalization.This document describes an algorithm for canonicalizing RDF datasets, based on a final CG report from the Credentials Community Group. This provides a foundation for comparing the differences between RDF datasets, digitally signing them, or generating short identifiers for them via hashing algorithms.

The CSS Working Group has published a first public Draft Note of CSS Snapshot 2022. This document collects together into one definition all the specs that together form the current state of Cascading Style Sheets (CSS) as of 2022. The primary audience is CSS implementers, not CSS authors, as this definition includes modules by specification stability, not Web browser adoption rate.

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

The Accessible Platform Architectures (APA) Research Questions Task Force (RQTF) welcomes feedback on the first public Draft Note of the Collaboration Tools Accessibility User Requirements. The purpose of this document is to outline various accessibility-related user needs, requirements and scenarios for collaboration tools. The solutions identified in this document are intended to influence the evolution of future accessibility guidelines, technical specifications, or features of collaboration tools and assistive technologies. They are relevant to software developers who contribute to any of these aspects of the collaborative experience. Please send comments by 30 December 2022.

The Accessible Rich Internet Applications Working Group invites implementations of the Candidate Recommendation Snapshot of Core Accessibility API Mappings 1.2. This document describes how user agents should expose semantics of web content languages to accessibility APIs. This helps users with disabilities to obtain and interact with information using assistive technologies. Documenting these mappings promotes interoperable exposure of roles, states, properties, and events implemented by accessibility APIs and helps to ensure that this information appears in a manner consistent with author intent.

The Verifiable Credentials Working Group has published a First Public Working Draft of the Verifiable Credential Data Integrity 1.0. This specification describes mechanisms for ensuring the authenticity and integrity of Verifiable Credentials and similar types of constrained digital documents using cryptography, especially through the use of digital signatures and related mathematical proofs.

The Immersive Web Working Group invites implementations of a new Candidate Recommendation of WebXR Augmented Reality Module – Level 1, which expands the WebXR Device API with the functionality available on AR hardware.

W3C announced today a Workshop on Permissions, 5–6 December 2022, in Munich, Germany. The event is hosted by Google.

The W3C Workshop on Permissions brings together security and privacy experts, UI/UX designers and researchers, browser vendors, OS developers, API authors, web publishers and users. We aim to address the privacy, security and usability challenges involved in controlling access to an increasingly powerful set of capabilities on the Web and other platforms.

The scope includes:

• user concerns and preferences, including those of vulnerable individuals and communities;
• better alignment of permission lifetime/duration with user tasks;
• risks and benefits of human-centric grouping/categorization of permissions and applications;
• challenges with novel capabilities;
• capability abuse threat models and mitigations;
• scoping of permissions to origins vs. applications, relation to same origin policy;
• UIs and controls;
• integrated permission control surfaces tailored to the capability itself;
• permission transparency, accountability, and control; and
• balancing well-specified permissions UX in standards with the ability for implementers to meet the future user and product requirements.

We aim to share experiences and user studies, leading to common understanding of how to ensure user comprehension and control of powerful capabilities while managing cognitive load.

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.
