First Public Working Draft: Chinese Layout Requirements
The Internationalization Working Group has published a First Public Working Draft of Requirements for Chinese Text Layout. The document describes requirements for Chinese script layout and text support on the Web and in digital publications. These requirements inform developers of Web technologies such as CSS, HTML, and SVG, and browser and tool implementers, about how to support users working in Chinese. The document is being developed by the Chinese Layout Task Force, part of the Internationalization Interest Group. This is still a very early draft and the group is looking for comments and contributions to support the further development of the document.

W3C Invites Implementations of TTML Text and Image Profiles for Internet Media Subtitles and Captions 1.0
The Timed Text Working Group invites implementation of the Candidate Recommendation of TTML Text and Image Profiles for Internet Media Subtitles and Captions 1.0.
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 text profile is a superset
of TTML Simple Delivery Profile for Closed Captions (US). Learn more
about the Video in the Web Activity.
Last Call: Canonical EXI
The Efficient XML Interchange Working Group has published a Last Call Working Draft of Canonical EXI.
Any EXI document is part of a set of EXI documents that are logically
equivalent within an application context, but which vary in physical
representation based on differences permitted by the Efficient XML
Interchange (EXI) Format 1.0 (Second Edition). This specification
describes a relatively simple method for generating a physical
representation, the canonical form, of an EXI document that accounts for
the permissible changes. An example of the applications targeted by
this specification is one that needs to guarantee non-repudiation using
XML Signature yet allows certain flexibility for intermediaries to
reconstitute the documents before they reach final destination without
breaking the signatures. Note that two documents may have differing
canonical forms yet still be equivalent in a given context based on more
elaborate application-specific equivalence rules which is out of scope
of this specification. Comments are welcome through 16 July. Learn more about the Extensible Markup Language (XML) Activity.

make Web content and Web applications more accessible to people with
disabilities. This document demonstrates how to use WAI-ARIA in HTML51,
which especially helps with dynamic content and advanced user interface
controls developed with Ajax, HTML, JavaScript, and related
technologies. Learn more about the HTML Activity.

Web MIDI API Draft Published
The Audio Working Group has published an updated Working Draft of Web MIDI API.
This specification provides users with a bridge between a Web browser
and their MIDI-capable devices, such as musical instruments, lighting
controls, or any other MIDI device. With this API, users can control or
exchange information with MIDI devices directly from the browser. The
Web MIDI API is a low-level feature, intended for use with other web
platform features, like the Web Audio API, with the goal of familiarity
for users of operating-system-level MIDI APIs, such as Apple’s CoreMIDI
and Microsoft’s Windows MIDI API. Learn more about the Rich Web Client Activity.
CSS Scroll Snap Points Module Level 1 First Public Draft Published; CSS Template Layout Module Note Published
The Cascading Style Sheets (CSS) Working Group has published a First Public Working Draft of CSS Scroll Snap Points Module Level 1.
This module contains features to control panning and scrolling behavior
with “snap points”. The group also published a Group Note of CSS Template Layout Module.
A grid template can be seen as a cross between table layout and
absolute positioning, and can also be associated with pages in paged
media to create page templates. Learn more about the Style Activity.

W3C Launches Web of Things initiative
W3C announced on 21 January 2015 a new Web of Things initiative
to develop Web standards for enabling open markets of applications and
services based upon connected sensors and actuators (the Internet of
Things) and the Web of data. Open standards will be essential to
realising the huge potential. We invite you to join the new Web of Things Interest Group
and drive work on use cases, requirements, and best practices. The aim
is to build a shared vision and identify specific opportunities for
standardization.
So far work on the Internet of Things has focused on the sensors and actuators and the associated communication technologies. Comparatively little attention has been given to what is needed for services to break free of today’s product silos. Web technologies are considered to be very promising, including the role of scripting languages like JavaScript for defining services. However, there is considerable work left to do to support discovery and interoperation of services, along with attention to security, privacy, accessibility and resilience in the face of faults and attacks.
The potential if we get this right is huge and will greatly expand the scale of the Web.
