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 .

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. Comments are welcome through  24 May 2018 .

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].

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. Comments are welcome through  22 May 2018 .

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...

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.

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.

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. Plea...

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 D...

3 April 2018 The W3C Advisory Committee has  elected  Kenneth Rohde Christiansen (Intel Corporation) to fill the  W3C Technical Architecture Group  (TAG) additional seat  created by the adoption of Process 2018 .
