8 August 2017  |  Archive The  Web Platform Working Group  invites implementations of  HTML 5.2  Candidate Recommendation. This specification defines the 5th major version, second 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.

8 August 2017  |  Archive The  CSS Working Group  invites implementations of  CSS Containment Module Level 1  Candidate Recommendation. This CSS module describes the  ‘contain’  property, which indicates that the element’s subtree is independent of the rest of the page. This enables heavy optimizations by user agents when used well. CSS  is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc.

W3C opened today registration for its first ever  W3C Publishing Summit  to be held 9-10 November 2017 in San Francisco, California, co-located with the W3C’s Technical Plenary and Advisory Committee meetings (TPAC 2017), and calls for speakers by 15 July 2017. The inaugural W3C Publishing Summit will show how publishers are using today’s Web technologies to make publications more effective and workflows more efficient. W3C launched last week its new  Publishing Working Group , just a few months following the combination of IDPF and W3C, with a mission to provide the necessary technologies on the Open Web Platform to make the combination of traditional publishing and the Web complete in terms of accessibility, usability, portability, distribution, archiving, offline access, and reliable cross referencing. Read the  Media Advisory  and  ‎Blog post  to learn about the event and major milestones for Publishing at W3C.

The  Device and Sensors Working Group  has published a Working Draft of  Orientation Sensor . This specification defines a base orientation sensor interface and concrete sensor subclasses to monitor the device’s physical orientation in relation to a stationary three dimensional Cartesian coordinate system.

The  Device and Sensors Working Group  has published a Group Note of  Motion Sensors Explainer . This explainer is an introduction to low-level and high-level motion sensors, their relationship, inner workings and common use-cases. Common cases of event filtering and sensor fusion are introduced with examples, showing how to apply that on sensors following the Generic Sensor API specification

The  Spatial Data on the Web Working Group  has published a Group Note of  Spatial Data on the Web Best Practices . This document advises on best practices related to the publication of spatial data on the Web and the use of Web technologies as they may be applied to location. The best practices presented here are intended for practitioners, including Web developers and geospatial experts, and are compiled based on evidence of real-world application. These best practices suggest a significant change of emphasis from traditional Spatial Data Infrastructures by adopting an approach based on general Web standards. As location is often the common factor across multiple datasets, spatial data is an especially useful addition to the Web of data.

25 April 2017  |  Archive Just two years after  launching its first HTML5 course  on W3Cx, W3C is expanding its program offerings with an  introductory level course in JavaScript development, created in partnership with  University Côte d’Azur . Additionally, W3C is launching a  “Front-End Web Developer” Professional Certificate  on edX.org, which consists of a suite of five W3Cx courses on the three foundational languages that power the Web: HTML5, CSS and JavaScript. All courses, designed to build or advance critical skills in Front-End Web development, are  open for enrollment  and will start on May 30.
