First Public Working Draft: Accessibility Requirements for People with Low Vision

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).

WCAG-EM Report Tool: Accessibility Evaluation Report Generator is Updated

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).

W3C Invites Implementations of WOFF File Format 2.0

The WebFonts Working Group invites implementation of the Candidate Recommendation of WOFF File Format 2.0. Based on experience with WOFF 1.0, which is widely deployed, this specification was developed to provide improved compression and thus lower use of network bandwidth, while still allowing fast decompression even on mobile devices. This is achieved by combining a content-aware preprocessing step and improved entropy coding, compared to the Flate compression used in WOFF 1.0.

The Working Group has also published a Group Note of WOFF 2.0 Evaluation Report. Web Open Font Format (WOFF) 2.0 is a proposed update to the existing WOFF 1.0 with improved compression. This report lists requirements for successful deployment, evaluates how the requirement may be met, and examines the compression gains and tradeoffs vs. code complexity, encode and decode time. This document is non-normative.

HTML 5.1 Draft Updated

The Web Platform Working Group has published an updated Working Draft of HTML 5.1. In this version of the 5th major version of the Hypertext Markup Language (HTML), the core language of the World Wide Web, new features continue to be introduced to help Web application authors, new elements continue to be introduced based on research into prevailing authoring practices, and special attention continues to be given to defining clear conformance criteria for user agents in an effort to improve interoperability.

Please, read more about the group’s plans to establish a regular rhythm of publication and how the group is working toward an HTML 5.1 Recommendation later this year.

Call for Review: TTML Profiles for Internet Media Subtitles and Captions 1.0 (IMSC1) Proposed Recommendation Published

The Timed Text Working Group has published a Proposed Recommendation of TTML Profiles for Internet Media Subtitles and Captions 1.0 (IMSC1). This document specifies two profiles of TTML1: a text-only profile and an image-only profile. These profiles are intended to be used across subtitle and caption delivery applications worldwide, thereby simplifying interoperability, consistent rendering and conversion to other subtitling and captioning formats. Comments are welcome through 08 April.

W3C Invites Implementations of WebIDL Level 1

The Web Platform Working Group invites implementation of the Candidate Recommendation of WebIDL Level 1. This document defines an interface definition language, Web IDL, that can be used to describe interfaces that are intended to be implemented in web browsers. Web IDL is an IDL variant with a number of features that allow the behavior of common script objects in the web platform to be specified more readily. How interfaces described with Web IDL correspond to constructs within ECMAScript execution environments is also detailed in this document. It is expected that this document acts as a guide to implementors of already-published specifications, and that newly published specifications reference this document to ensure conforming implementations of interfaces are interoperable.

W3C Invites Implementations of CSS Flexible Box Layout Module Level 1

The Cascading Style Sheets (CSS) Working Group invites implementation of the Candidate Recommendation of CSS Flexible Box Layout Module Level 1. This specification describes a CSS box model optimized for user interface design. In the flex layout model, the children of a flex container can be laid out in any direction, and can “flex” their sizes, either growing to fill unused space or shrinking to avoid overflowing the parent. Both horizontal and vertical alignment of the children can be easily manipulated. Nesting of these boxes (horizontal inside vertical, or vertical inside horizontal) can be used to build layouts in two dimensions.

CSV on the Web Working Group: 3 Notes Published

The CSV on the Web Working Group has published 3 Group Notes:

  • CSV on the Web: Use Cases and Requirements: A large percentage of the data published on the Web is tabular data, commonly published as comma separated values (CSV) files. The CSV on the Web Working Group aim is to specify technologies that provide greater interoperability for data dependent applications on the Web when working with tabular datasets comprising single or multiple files using CSV, or similar, format. This document lists the use cases compiled by the Working Group that are considered representative of how tabular data is commonly used within data dependent applications.
  • Embedding Tabular Metadata in HTML: The Model for Tabular Data and Metadata on the Web describes mechanisms for extracting metadata from CSV documents starting with either a tabular data file, or a metadata description. In the case of starting with a CSV document, a procedure is followed to locate metadata describing that CSV. Alternatively, processing may begin with a metadata file directly, which references the tabular data file(s). However, in some cases, it is preferred to publish datasets using HTML rather than starting with either CSV or metadata files.
  • CSV on the Web: A Primer: CSV is one of the most popular formats for publishing data on the web. It is concise, easy to understand by both humans and computers, and aligns nicely to the tabular nature of most data. The CSV on the Web Working Group has developed standard ways to express useful metadata about CSV files and other kinds of tabular data. This primer takes you through the ways in which these standards work together.

W3C Accelerates Efforts to Build a More Secure Web with Launch of Web Authentication Working Group

W3C Announced today the launch of the Web Authentication Working Group whose goal is to develop standards using strong cryptographic operations in place of password exchange. This approach offers a more secure and flexible alternative to password-based log-ins on the Web, often seen as being annoying to use and offering weak protection.

When strong authentication is easy to deploy, we make the Web safer for daily use, personal and commercial,” said Sir Tim Berners-Lee, Web Inventor and W3C Director. “With the scope and frequency of attacks increasing, it is imperative for W3C to develop new standards and best practices for increased security on the Web.”

The W3C’s Web Authentication technical work is being accelerated thanks to a W3C member submission of FIDO 2.0 Web APIs from members of the FIDO Alliance. The submitted APIs are intended to ensure standards-based strong authentication across all Web browsers and related Web platform infrastructure.

The new Web Authentication Working Group’s first meeting will take place 4 March 2016 in San Francisco, conveniently timed for people who are also attending the RSA USA Conference. For more information about the Web Authentication Working Group, see the press release.
