Call for Review: Canonical EXI is a W3C Proposed Recommendation

26 April 2018

The Efficient eXtended Interchange (EXI) Working Group has published a W3C Proposed Recommendation of Canonical EXI, a specification that describes the method for generating a canonical form of an EXI document. The main application of this specification is to guarantee non-repudiation using XML Signature, while allowing certain flexibility for intermediaries to reconstitute the documents before they reach final destination without breaking the signatures.

Comments are welcome through 24 May 2018.

Call for Review: WebDriver is a W3C Proposed Recommendation

26 April 2018

The Browser Testing and Tools Working Group has published a Proposed Recommendation of WebDriver. WebDriver is a remote control interface that enables introspection and control of user agents. It provides a platform- and language-neutral wire protocol as a way for out-of-process programs to remotely instruct the behavior of web browsers. Provided is a set of interfaces to discover and manipulate DOM elements in web documents and to control the behavior of a user agent. It is primarily intended to allow web authors to write tests that automate a user agent from a separate controlling process, but may also be used in such a way as to allow in-browser scripts to control a — possibly separate — browser.

TTML Profiles for Internet Media Subtitles and Captions 1.0.1 (IMSC1) is now a W3C Recommendation

24 April 2018

The Timed Text Working Group has published TTML Profiles for Internet Media Subtitles and Captions 1.0.1 (IMSC1) as a W3C Recommendation. 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. It is feasible to create documents that simultaneously conform to both [ttml10-sdp-us] and the text-only profile. The document defines extensions to [TTML1], as well as incorporates extensions specified in [ST2052-1] and [EBU-TT-D]. Both profiles are based on [SUBM].

Call for Review: Web Content Accessibility Guidelines (WCAG) 2.1 is a W3C Proposed Recommendation

24 April 2018

The Accessibility Guidelines Working Group has published a Proposed Recommendation of Web Content Accessibility Guidelines (WCAG) 2.1. WCAG 2.1 covers a wide range of recommendations for making Web content more accessible. Following these guidelines will make content more accessible to a wider range of people with disabilities, including blindness and low vision, deafness and hearing loss, limited movement, speech disabilities, photosensitivity, and combinations of these, and some accommodation for learning disabilities and cognitive limitations; but will not address every user need for people with these disabilities. These guidelines address accessibility of web content on desktops, laptops, tablets, and mobile devices. Following these guidelines will also often make Web content more usable to users in general.

W3C Invites Implementations of Timed Text Markup Language 1 (TTML1) (Third Edition)

24 April 2018

The Timed Text Working Group invites implementations of Timed Text Markup Language 1 (TTML1) (Third Edition) Candidate Recommendation. This document specifies Timed Text Markup Language (TTML), Version 1, also known as TTML1, in terms of a vocabulary and semantics thereof. The Timed Text Markup Language is a content type that represents timed text media for the purpose of interchange among authoring systems. Timed text is textual information that is intrinsically or extrinsically associated with timing information. It is intended to be used for the purpose of transcoding or exchanging timed text information among legacy distribution content formats presently in use for subtitling and captioning functions. In addition to being used for interchange among legacy distribution content formats, TTML Content may be used directly as a distribution format, for example, providing a standard content format to reference from a <track> element in an HTML5 document, or a <text> or <textstream> media element in a [SMIL 2.1] document.

W3C Tutorials and Track on Web Conference 2018

24 April 2018

This year, W3C once again joins the Web Conference 2018, previously known as WWW2018 with W3C tutorials and track.

The W3C tutorials on Monday and Tuesday focus on Data Visualization, Media and Audio on the Web. The W3C Track on Friday invites conference attendees to talk to experts from W3C members and W3C team on topics including New Trends on the Web Platform, WebAssembly, WebXR, Web of Things, Social Web Protocols and the Foundations of Trust as well as Intelligent Search on the Web. A panel about the future of the Web will be hosted at the end of the W3C track and we expect active interaction with the audience on site with the recent hot topics they care about for the Web. Also, W3C will join the exhibition of the Web Conference and we welcome conference attendees to visit our booth.

First Public Working Draft: CSS Layout API Level 1

12 April 2018

The CSS Working Group has published a First Public Working Draft of CSS Layout API Level 1. This specification describes an API which allows developers to layout a box in response to computed style and box tree changes.

Login with no password – Major Standards Milestone in Global Effort Towards Simpler, Stronger Authentication on the Web

10 April 2018

W3C and the FIDO Alliance have achieved a major standards milestone in the global effort to bring simpler yet stronger web authentication to users around the world. The completion of the FIDO2 standardization efforts, the recent advancement of Web Authentication (WebAuthn) to Candidate Recommendation, –and the commitment of leading browser vendors to implement– enable users to login easily to online services with desktop or mobile devices with phishing-resistant security. WebAuthn, a standard web API to give users new methods to securely authenticate across sites and devices, has been developed in coordination with FIDO Alliance and is a core component of the FIDO2 Project along with FIDO’s Client to Authenticator Protocol (CTAP)specification, which enables an external authenticator, such as a security key or a mobile phone, to communicate strong authentication credentials locally over USB, Bluetooth or NFC to the user’s computer or tablet. Please, read the joint Press release and testimonials from W3C Members.

First Public Working Note of the Web of Things Protocol Binding Templates; updated WoT drafts

5 April 2018

The Web of Things provides layered interoperability between Things by using the WoT Interfaces and enables applications to interact with and orchestrate connected Things at Web scale. The Web of Things (WoT) Working Group has published today:

• A First Public Working Group Note of the Web of Things (WoT) Protocol Binding Templates. This document describes the initial set of design pattern and vocabulary extensions to the WoT Thing Description. Protocol Binding Templates consist of reusable vocabulary and design pattern extensions to the WoT Thing Description format that enable an application client to interact, using a consistent interaction model, with Things that expose diverse protocols and protocol usage. See the specification to discover how to contribute to this draft.
• An updated Working Draft of the Web of Things (WoT) Thing Description. This specification describes a formal model and common representation for a Web of Things Thing Description, which describes the metadata and interfaces of Things, where a Thing is an abstraction of a physical entity that provides interactions to and participates in the Web of Things. In addition to physical entities, Things can also represent virtual entities. A Thing Description instance can be hosted by the Thing itself or hosted externally due to Thing’s resource restrictions (e.g. limited memory space) or when a Web of Things-compatible legacy device is retrofitted with a Thing Description.
• An updated Working Draft of the Web of Things (WoT) Scripting API. This specification describes a programming interface representing the WoT Interface that allows scripts run on a Thing to discover and consume (retrieve) other Things and to expose Things characterized by Properties, Actions and Events. Scripting is an optional “convenience” building block in WoT and it is typically used in gateways that are able to run a WoT Runtime and script management, providing a convenient way to extend WoT support to new types of endpoints and implement WoT applications like Thing Directory.
