Webmention is a W3C Proposed Recommendation

The W3C Social Web Working Group is calling for review of Webmention, which is now a Proposed Recommendation. Webmention provides a mechanism for a webpage to notify another webpage when it mentions its URL, and when the content around the mention changes or is deleted. From the receiver’s perspective, it’s a way to request notifications when other sites mention it. This mechanism is a core building block for a decentralized (social) Web, because it allows sites to automatically learn about connected content, without any prior setup or agreement. For users, an immediate benefit is cross-site comments. Comments on the PR are welcome until 30 November.

Pointer Lock is a W3C Recommendation

The Web Platform Working Group has published a W3C Recommendation of Pointer Lock. This specification defines an API that provides scripted access to raw mouse movement data while locking the target of mouse events to a single element and removing the cursor from view. This is an essential input mode for certain classes of applications, especially first person perspective 3D applications and 3D modeling software.

Call for Review: Media Source Extensions™ Proposed Recommendation Published

The HTML Media Extensions Working Group has published a Proposed Recommendation of Media Source Extensions™.

This specification allows JavaScript to dynamically construct media streams for <audio> and <video>. It defines a MediaSource object that can serve as a source of media data for an HTMLMediaElement. MediaSource objects have one or more SourceBuffer objects. Applications append data segments to the SourceBuffer objects, and can adapt the quality of appended data based on system performance and other factors. Data from the SourceBuffer objects is managed as track buffers for audio, video and text data that is decoded and played. Byte stream specifications used with these extensions are available in the byte stream format registry. Comments are welcome through 1 November 2016.

The group also published the following specifications as Working Group Notes:

• Media Source Extensions Byte Stream Format Registry


• MPEG-2 TS Byte Stream Format


• MPEG Audio Byte Stream Format


• ISO BMFF Byte Stream Format


• WebM Byte Stream Format

Call for Review: WebIDL Level 1 Proposed Recommendation Published

The Web Platform Working Group has published a Proposed Recommendation of WebIDL Level 1. This document defines an interface definition language, Web IDL, that can be used to describe interfaces that are intended to be implemented in web browsers. Web IDL is an IDL variant with a number of features that allow the behavior of common script objects in the web platform to be specified more readily. How interfaces described with Web IDL correspond to constructs within ECMAScript execution environments is also detailed in this document. It is expected that newly published specifications reference this document to ensure conforming implementations of interfaces are interoperable. Comments are welcome through 14 October.
