Encrypted Media Extensions (EME) is a W3C Recommendation

   18 September 2017

   The HTML Media Extensions Working Group published "Encrypted Media Extensions (EME)" as a W3C Recommendation today. Encrypted Media Extensions (EME), which extends the ‘HTMLMediaElement’ element of the HTML specification, is an Application Programming Interface (API) that allows playback of protected content in Web browsers. Combined with W3C’s Recommendation Media Source Extensions (MSE) which provides the API for streaming video, EME is the most common practice today that allows Web developers to stop using plugins to deliver commercial quality video over the Web. Please read more in our Press Release.

First Public Working Drafts: WoT Architecture; WoT Thing Description; WoT Scripting API

   15 September 2017

   The Web of Things (WoT) Working Group has published the following three First Public Working Drafts:


   "Web of Things (WoT) Architecture" : This document describes the abstract architecture for the W3C Web of Things, which consists of three initial building blocks, i.e., (1) WoT Thing Description, (2) WoT Scripting API and (3) WoT Binding Templates.


   "Web of Things (WoT) Thing Description" : This document describes a formal model and common representation for a Web of Things Thing Description. A Thing Description 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.


   "Web of Things (WoT) Scripting API" : This document 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.


   The group is planning to publish the third building block, WoT Binding Templates, as a First Public Working Draft shortly.

W3C Invites Implementations of Payment Request API; Payment Method Identifiers

   14 September 2017

   The World Wide Web Consortium (W3C) today called for broad implementation and testing of Web technologies to make online checkout easier for users and improve conversions and security for merchants. All major browser makers are now implementing "Payment Request API" and "Payment Method Identifiers," which today advanced to Candidate Recommendation Status. The Web Payments Working Group encourages merchants, Web developers, and users to experiment with these early implementations and provide feedback to the group. In parallel, the Working Group will be expanding its test suite for the API to help ensure browser interoperability. Read more in the W3C Media Advisory and blog post.


First Public Working Draft: Intersection Observer

   14 September 2017

   The Web Platform Working Group has published a First Public Working Draft of "Intersection Observer." This specification describes an API that can be used to understand the visibility and position of DOM elements (“targets”) relative to a containing element or to the top-level viewport (“root”). The position is delivered asynchronously and is useful for understanding the visibility of elements and implementing pre-loading and deferred loading of DOM content.
