The project covers a subset of the public-facing pages of our Website and will span the next 10 months. Please, read more in our joint press release . We are aiming for this phase to scale well to cover the redesign expectations for the rest of the site. Future phases will include the Member and Team spaces, internal Work Groups homepages, specifications template, mailing lists archives, W3C Community Groups and Business Groups. The current website was implemented ten years ago and is no longer as effective in supporting W3C’s mission and goals as it could be. We believe that by implementing current web best practices and technologies, revising the information architecture, creating a content strategy and revamping the visual design , we can provide our audiences with the best information in a more user-friendly fashion, motivate participation in the organization, and communicate the nature and impact of W3C more effectively. First Public Working Draft: XR Accessibility User Requirements 13 February 2020 | Archive The Accessible Platform Architectures Working Group has published a First Public Working Draft of XR Accessibility User Requirements . This document lists user needs and requirements for people with disabilities when using virtual reality or immersive environments, augmented or mixed reality and other related technologies (XR). This document is most explicitly not a collection of baseline requirements. It is also important to note that some of the requirements may be implemented at a system or platform level, and some may be authoring requirements. First Public Working Drafts: Resize Observer; CSS Scroll Anchoring Module Level 1 11 February 2020 | Archive The CSS Working Group has published two First Public Working Drafts today: Resize Observer : This specification describes an API for observing changes to Element’s size. CSS Scroll Anchoring Module Level 1 : Changes in DOM elements above the visible region of a scrolling box can result in the page moving while the user is in the middle of consuming the content. This spec proposes a mechanism to mitigate this jarring user experience by keeping track of the position of an anchor node and adjusting the scroll offset accordingly. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, etc. Trace Context is a W3C Recommendation 6 February 2020 | Archive The Distributed Tracing Working Group has published Trace Context as a W3C Recommendation. This specification defines standard HTTP headers and a value format to propagate context information that enables distributed tracing scenarios. The specification standardizes how context information is sent and modified between services. Context information uniquely identifies individual requests in a distributed system and also defines a means to add and propagate provider-specific context information. W3C Workshop Report: Inclusive Design for Immersive Web Standards 6 February 2020 | Archive W3C is pleased to announce a report from the W3C Workshop on Inclusive Design for Immersive Web Standards , held on 5-6 November 2019 in Seattle, WA, USA. This report contains a brief summary and collects highlights from the individual sessions, with links to the presentation slides. Workshop participants learned from existing approaches that have been taken in making XR experiences (on and off the Web) accessible before looking at what lessons could be derived from these existing research and experiments in the context of the Immersive Web architecture. These lessons brought forward four aspects of accessible XR experiences: visual interactions, motricity considerations, audio aspects and assistive technologies adaptation. The relevant follow-up work in W3C spans across at least 6 standardization Working Groups and 6 pre-standardization and incubation Community Groups, and also intersects with at least 3 Khronos Working Groups – pointing toward the need for a strong coordination effort to ensure systematic and consistent progress for the Web platform. We propose to host this coordination in the Inclusive Design for the Immersive Web Community Group via a dedicated github repository . We thank our host, Pluto VR, Maveron, We Make Reality, Virtual World Society and Seattle Immersive Technology Association, our sponsors, Google, Twitch and Samsung Internet, the Program Committee , and all participants for making this event possible. Data Catalog Vocabulary (DCAT) version 2 is a W3C Recommendation 4 February 2020 | Archive The W3C Dataset Exchange Working Group has published Data Catalog Vocabulary (DCAT) – Version 2 as a W3C Recommendation. DCAT defines an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. The specification defines the schema and provides examples for its use. Version 2 extends the original DCAT standard in line with community practice while supporting diverse approaches to data description and dataset exchange. Postponed: W3C Workshop on Web & Machine Learning 14 January 2020 | Archive 2020-02-13 Update: Given the current challenges and restrictions around international travel, the Program Committee has made the decision to postpone the workshop to a later date. W3C announced today a Workshop on Web & Machine Learning , 24-25 March 2020, in Berlin, Germany. The event is hosted by Microsoft. The primary goal of the workshop is to bring together providers of Machine Learning tools and frameworks with Web platform practitioners to enrich the Open Web Platform with better foundations for machine learning. The secondary goals of the workshop are as follows: Understand how machine learning fits into the Web technology stack, Understand how browser-based machine learning fits into the machine learning ecosystem, Explore the impact of machine learning technologies on Web browsers and Web applications, Evaluate the opportunities for standardization around machine learning APIs and formats. Expected topics of discussion include: Dedicated machine learning APIs for browsers as explored by the Machine Learning for the Web Community Group Integration of browser-provided data sources in machine learning workflows Layering and interoperability of machine learning APIs with other computing APIs (e.g. WebGPU, WebAssembly) Domain-specific machine learning APIs Interchange format for machine learning models on the Web Client- and cloud-based machine learning interactions On-device machine learning training in browsers Risks and benefits of browser-based machine learning on privacy, security, accessibility Using machine learning primitives to help improve accessibility of Web pages and applications Machine learning frameworks for the Web Machine learning hardware accelerators 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 . Registration is available online due by 21 February 2020 .
