A new session of the Responsive Web Design training course is open for registration, to start 3 March 2016. Students will learn step by step using an approach that focuses on HTML and CSS and their best practices to make Web sites work across devices with their different viewport widths. This course edition contains a new section dedicated to Flexbox properties that are very useful in a responsive layout. Taught by trainer Frances de Waal, this course is 5 weeks long. Enroll before 14 February to benefit from the early bird rate! Learn more about W3DevCampus, W3C’s online training for Web developers.

The Social Web Working Group has published two First Public Working Drafts:

Micropub: Micropub is an open API standard that is used to create posts on one’s own domain using third-party clients. Web apps and native apps (e.g. iPhone, Android) can use Micropub to post short notes, photos, events or other posts to your own site.

ActivityPub: The ActivityPub protocol is a social networking protocol based upon the ActivityStreams 2.0 data format. It is based upon experience gained from implementing and working with the OStatus and Pump.io protocols.

The Data on the Web Best Practices Working Group has published the near final version of its Dataset Usage Vocabulary. It is designed to answer the natural desire of publishers to be able to see how the data that they have gone to the effort of sharing is being used. Dataset users can encourage continued publication by providing that information.

By specifying a number of foundational concepts used to collect dataset consumer feedback, experiences, and citation references associated with a dataset, the Dataset Usage Vocabulary allows APIs to be written to support collaboration across the Web by structurally publishing consumer opinions and experiences, and provide a means for data consumers and producers to advertise and search for published open dataset usage.

The Efficient XML Interchange Working Group has published a Working Draft of Efficient XML Interchange (EXI) for JSON. The Efficient XML Interchange (EXI) format is a compact representation that simultaneously optimizes performance and the utilization of computational resources. The EXI format was designed to support XML representation. With a relatively small set of transformations it may also be used for JSON, a popular format for exchange of structured data on the Web.

The Timed Text Working Group invites implementation of the Candidate 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.

The Web Application Security Working Group has published a Working Draft of Content Security Policy Level 3. This document defines a mechanism by which web developers can control the resources which a particular page can fetch or execute, as well as a number of security-relevant policy decisions.
