W3C is pleased to announce that Tim Berners-Lee, Web Inventor and W3C Director, will deliver a keynote address on Tuesday, 10 May 2016 at IDPF DigiCon, the annual digital publishing conference hosted by the International Digital Publishing Forum (IDPF) and co-located with Book Expo America (BEA) at McCormick Place in Chicago, Illinois, USA. In his talk, “Realizing the Vision of Publishing Technology with Web Technology” Berners-Lee will preview potential new ways of reading, authoring and publishing in the future that are being made possible by the new rich media environment for publishing.
For the past three years W3C’s Digital Publishing Activity has been collaborating with the IDPF and other publishing industry groups to bring key requirements of the publishing industry to the Web. For more information, see the Media Advisory. To register for the DigiCon event, see registration form.
The Web Platform Working Group has published a W3C Recommendation of Web Storage (Second Edition). This specification defines an API for persistent data storage of key-value pair data in Web clients. It introduces two related mechanisms, similar to HTTP session cookies, for storing name-value pairs on the client side. The first mechanism is designed for scenarios where the user is carrying out a single transaction, but could be carrying out multiple transactions in different windows at the same time. The second mechanism is designed for storage that spans multiple windows, and lasts beyond the current session.
The Cascading Style Sheets (CSS) Working Group has published a Working Draft of Cascading Style Sheets Level 2 Revision 2 (CSS 2.2) Specification. This specification defines Cascading Style Sheets level 2. CSS is a style sheet language that allows authors and users to attach style (e.g. fonts and spacing) to structured documents (e.g. HTML documents and XML applications). By separating the presentation style of documents from the content of documents, CSS simplifies Web authoring and site maintenance.
The Web Performance Working Group has published a Working Draft of Reporting API 1. This document defines a generic reporting framework which allows web developers to associate a set of named reporting endpoints with an origin. Various platform features (like Content Security Policy, Network Error Reporting, and others) will use these endpoints to deliver feature-specific reports in a consistent manner.
W3C is pleased to launch today a new course: HTML5 Introduction. Taught by Intel and W3C experts, this course presents the basic building blocks of Web design and style, using basics of HTML5 and a few CSS features. We encourage future Web developers to enroll soon to learn how to build Web sites that look great. This introductory 6-week course nicely completes the “Learn HTML5 from W3C” XSeries group of three courses – all are open for registration.
The Device APIs Working Group has published a Proposed Recommendation of Battery Status API. The Battery Status API specification defines a means for web developers to programmatically determine the battery status of the hosting device. Without knowing the battery status of a device, a web developer must design the web application with an assumption of sufficient battery level for the task at hand. This means the battery of a device may exhaust faster than desired because web developers are unable to make decisions based on the battery status. This specification defines an API that provides information about the battery status of the hosting device. Comments are welcome through 29 April.
The Education and Outreach Working Group (EOWG) and the Web Content Accessibility Guidelines Working Group (WCAG WG) have published a new version of How to Meet WCAG 2.0: A customizable quick reference to Web Content Accessibility Guidelines (WCAG) 2.0 requirements (success criteria) and techniques. It provides a customizable view of WCAG 2.0 resources, including: Web Content Accessibility Guidelines (WCAG) 2.0 web standard, Techniques for WCAG 2.0 implementation guidance, and Understanding WCAG 2.0 supporting information. Information on these resources is provided in the WCAG Overview and The WCAG 2.0 Documents. This new version provides a significantly updated user interface and additional functionality to filter by Tags that are categorized under Developing, Interaction Design, Content Creation, and Visual Design. (The previous version is still available.) Learn more about the Web Accessibility Initiative (WAI).
Accessibility Requirements for People with Low Vision, developed by the Low Vision Accessibility Task Force (LVTF), was published today by the Web Content Accessibility Guidelines Working Group (WCAG WG). This document describes what people with low vision need for electronic content, tools, and technologies to be accessible. It includes an overview of low vision and describes specific user needs. It does not set technical requirements. It provides the background for planned future work on guidance for making web content, tools, and technologies accessible to people with low vision. Comments are welcome by 14 April 2016. Read about the Web Accessibility Initiative (WAI).
Education and Outreach Working Group (EOWG) has published an updated version of the WCAG-EM Report Tool: Website Accessibility Evaluation Report Generator. The tool helps you generate website accessibility evaluation reports according to Website Accessibility Conformance Evaluation Methodology (WCAG-EM). WCAG-EM is an informative W3C Working Group Note. It describes an approach for evaluating how websites, including web applications and websites for mobile devices, conform to Web Content Accessibility Guidelines (WCAG) 2.0. We welcome feedback on this version of the WCAG-EM Report Tool and suggestions for improvements for the next version. Learn more about the Web Accessibility Initiative (WAI).
