W3C Invites Implementations of HTML 5.1

The Web Platform Working Group invites implementation of the Candidate Recommendation of HTML 5.1. This specification defines the 5th major version, first minor revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, 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.

Upcoming Workshop: Smart Descriptions and Smarter Vocabularies (SDSVoc)

W3C announced today Smart Descriptions & Smarter Vocabularies (SDSVoc) Workshop, 30 November – 1 December 2016, in Amsterdam, hosted by CWI and organized in conjunction with the EU funded project VRE4EIC.

This workshop aims to clarify the steps needed to improve communication between data repositories and applications that use that data, such as virtual research environments. Applications may simply discover data or visualize it, manipulate it, discuss it, correct it, describe it, republish it, etc. The outcome may be a new W3C Working Group chartered to extend DCAT and determine how human and machine-readable metadata profiles are defined and made discoverable. A further aim is to explore how W3C can best support vocabulary development for a variety of communities.

W3C membership is not required to participate. The event is open to all, subject to registration and the capacity of the venue. Position statements will be required to secure a speaking slot, due by 9 October 2016.

First Public Working Drafts published by the CSS WG and TAG

The Cascading Style Sheets (CSS) Working Group and Technical Architecture Group (TAG) have published four Working Drafts:

  • CSS Typed OM Level 1: Converting CSSOM value strings into meaningfully typed JavaScript representations and back can incur a significant performance overhead. This specification exposes CSS values as typed JavaScript objects to facilitate their performant manipulation.
  • CSS Properties and Values API Level 1: This CSS module defines an API for registering new CSS properties. Properties registered using this API are provided with a parse syntax that defines a type, inheritance behaviour, and an initial value.
  • CSS Painting API Level 1: The paint stage of CSS is responsible for painting the background, content and highlight of a box based on that box’s geometry (as generated by the layout stage) and computed style. This specification describes an API which allows developers to paint a part of a box in response to geometry/computed style changes with an additional function.
  • Worklets Level 1: This specification defines an API for running scripts in stages of the rendering pipeline independent of the main javascript execution environment.

Reporting API 1 Note Published

The Web Performance Working Group has published a Group Note 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 Advisory Committee Elects Advisory Board

The W3C Advisory Committee has filled five open seats on the W3C Advisory Board. Created in 1998, the Advisory Board provides guidance to the Team on issues of strategy, management, legal matters, process, and conflict resolution. Beginning 1 July 2016, the nine Advisory Board participants are Tantek Çelik (Mozilla), Michael Champion (Microsoft), Virginie Galindo (Gemalto), Jay (Junichi) Kishigami (NTT), Charles McCathie Nevile (Yandex), David Singer (Apple), Léonie Watson (The Paciello Group), Chris Wilson (Google) and Judy Zhu (Alibaba). Many thanks to Soohong Daniel Park (Samsung Electronics), whose term ends this month. Read more about the Advisory Board.

First Public Working Draft: Semantic Sensor Network Ontology

The Spatial Data on the Web Working Group has published a Working Draft of Semantic Sensor Network Ontology. The Semantic Sensor Network Ontology (commonly known as “SSN” or sometimes “SSNO”) is an OWL-2 DL ontology for describing sensors and the observations they make of the physical world. SSN is published in a modular architecture that supports the judicious use of “just enough” ontology for diverse applications, including satellite imagery, large scale scientific monitoring, industrial and household infrastructure, citizen observers, and Web of Things. SSN is described and examples of its use are given.

First Public Working Draft: Web Authentication: A Web API for accessing scoped credentials

The Web Authentication Working Group has published a Working Draft of Web Authentication: A Web API for accessing scoped credentials. This specification defines an API that enables web pages to access WebAuthn compliant strong cryptographic credentials through browser script. Conceptually, one or more credentials are stored on an authenticator, and each credential is scoped to a single Relying Party. Authenticators are responsible for ensuring that no operation is performed without the user’s consent. The user agent mediates access to credentials in order to preserve user privacy. Authenticators use attestation to provide cryptographic proof of their properties to the relying party. This specification also describes a functional model of a WebAuthn compliant authenticator, including its signature and attestation functionality.

W3C Opens New United Kingdom and Ireland Office

Image of WSI host of the W3C UK and Ireland OfficeW3C is pleased to announce the selection of Web Science Institute at the University of Southampton, to host UK & Ireland Office. The W3C United Kingdom and Ireland Office will be staffed by Susan Davies, Coordination Manager for the WSI, who will become the Office Manager, and Professor Leslie Carr, Director of the WSI Centre for Doctoral Training, who will act in a Senior Advisor role. W3C Offices act as local points of contact for W3C work and help ensure that W3C and its specifications reach an international audience. Professor Dame Wendy Hall, Executive Director of the WSI commented, “The WSI is excited to be taking on this important role within the W3C. The University of Southampton has played an active role in the Web community since 1994 and has been a member of the W3C since 1998, promoting new futures of the Web through W3C community groups including the Web Observatory, Annotations and Web of Things.” Read more in our press release, and learn more about the W3C Offices program.

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. The 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.

World Wide Web Consortium (W3C) Expands Emmy® Award-Winning Work on Captions and Subtitles for More Accessible Video Content

Picture of a movie clip showing the subtitlesW3C has published new global guidelines, TTML Profiles for Internet Media Subtitles and Captions 1.0 IMSC1 as a W3C Recommendation, that will improve accessibility and make it easier and less expensive for distributors of online video content to deliver subtitles and closed captions worldwide.

An application of the W3C’s Emmy® award-winning Timed Text Markup Language (TTML), TTML Profiles for IMSC1 simplifies authoring and processing of subtitles and captions worldwide by harmonizing popular profiles of TTML. In addition, W3C’s TTML Working Group updated the working draft of TTML 2, the second version of Timed Text Markup Language (TTML), which adds features introduced in IMSC1 as well as other improvements, such as additional support for East Asian language typography, stereoscopic presentations, and mapping to HTML and CSS.

Described as a harmonization point for subtitling practices around the world, the IMSC1 global standard helps to bring together standards, rather than creating further fragmentation. Compatible with common media container formats, IMSC1 integrates with existing workflows, content libraries, and captioning requirements by offering conversion from popular captioning formats.
