Web Cryptography API Draft Published
13 September 2012 | Archive
http://www.w3.org/News/2012#entry-9564
The Web Cryptography Working Group has published the First
Public Working Draft of "Web Cryptography API." This
specification describes a JavaScript API for performing basic
cryptographic operations in web applications, such as hashing,
signature generation and verification, and encryption and
decryption. Additionally, it describes an API for applications
to generate and/or manage the keying material necessary to
perform these operations. Key storage is provided for both
temporary and permanent keys. Access to keying material is
contingent on the same origin policy. Uses for this API range
from user or service authentication, document or code signing,
and the confidentiality and integrity of communications. Learn
more about the Security Activity.

Simple Delivery Profile for Closed Captions (US) Draft Published
13 September 2012 | Archive
http://www.w3.org/News/2012#entry-9563
The Timed Text Working Group has published the First Public
Working Draft of "Simple Delivery Profile for Closed Captions
(US)." This document defines the behavior expected of a
presentation processor using the player constraints for such an
online delivery profile. The Simple Online Delivery profile is
focused on streamlined delivery of closed captions on the
Internet. This interoperability profile supports core TTML
features to deliver content originating legacy formats such as
CEA-608 and -708 content, and is targeted primarily for
delivery in US markets. The Simple Delivery Profile for Closed
Captions focuses interoperability using TTML 1.0 to support
delivery of closed captions for video content. Other profiles
based on TTML 1.0 may target other types of subtitles such as
on-screen text or graphics. This interoperability profile is a
proper subset of TTML 1.0 plus features required to support US
Government closed captioning requirements for online
presentation. Learn more about the Video in the Web Activity.

Three drafts published by the CSS Working Group
11 September 2012 | Archive
http://www.w3.org/News/2012#entry-9562
The Cascading Style Sheets (CSS) Working Group has published
three Working Drafts today.
http://www.w3.org/Style/CSS/members
* CSS Conditional Rules Module Level 3. This module contains
the features of CSS for conditional processing of parts of
style sheets, conditioned on capabilities of the processor
or the document the style sheet is being applied to. It
includes and extends the functionality of CSS level 2,
which builds on CSS level 1. The main extensions compared
to level 2 are allowing nesting of certain at-rules inside
'@media', the addition of the '@supports' and '@document'
rules for conditional processing.
* CSS Image Values and Replaced Content Module Level 4. This
module contains the features of CSS level 4 relating to the
<image> type and replaced elements. It includes and extends
the functionality of CSS Image Values and Replaced Content
Module Level 3. The main extensions compared to level 3 are
several additions to the ‘<image>’ type, additions to the
‘<gradient>’ type, extensions to the ‘image()’ function,
definitions for interpolating several ‘<image>’ types, and
several properties controlling the interaction of replaced
elements and CSS's layout models.
* CSS Transforms. CSS transforms allows elements styled with
CSS to be transformed in two-dimensional or
three-dimensional space. This specification is the
convergence of the CSS 2D transforms, CSS 3D transforms and
SVG transforms specifications.

HTML+RDFa 1.1 Draft Published
11 September 2012 | Archive
http://www.w3.org/News/2012#entry-9561
The RDFa Working Group has published a Working Draft of
"HTML+RDFa 1.1."This specification defines rules and
guidelines for adapting the RDFa Core 1.1 and RDFa Lite 1.1
specifications for use in HTML5 and XHTML5. The rules defined
in this specification not only apply to HTML5 documents in
non-XML and XML mode, but also to HTML4 and XHTML documents
interpreted through the HTML5 parsing rules. Learn more about
the Semantic Web Activity.

Last Call: Constraints of the Provenance Data Model
11 September 2012 | Archive
http://www.w3.org/News/2012#entry-9560
The Provenance Working Group has published a Last Call Working
Draft of "Constraints of the Provenance Data Model." This
document defines a subset of PROV instances called valid PROV
instances. The intent of validation is ensure that a PROV
instance represents a history of objects and their interactions
which is consistent, and thus safe to use for the purpose of
logical reasoning and other kinds of analysis. Valid PROV
instances satisfy certain definitions, inferences, and
constraints. These definitions, inferences, and constraints
provide a measure of consistency checking for provenance and
reasoning over provenance. They can also be used to normalize
PROV instances to forms that can easily be compared in order to
determine whether two PROV instances are equivalent. Validity
and equivalence are also defined for PROV bundles and
documents. Comments are welcome through 10 October. Learn more
about the Semantic Web Activity.

Mobile Accessibility Resources Updated
10 September 2012 | Archive
http://www.w3.org/News/2012#entry-9559
The Education and Outreach Working Group (EOWG) published
updated resources related to mobile accessibility. They cover
how mobile accessibility is addressed in existing W3C
standards/guidelines, and how the overlap between mobile web
design/development and accessibility strengthens the business
case. Learn more from the Mobile Accessibility Resources e-mail
and read about the Web Accessibility Initiative (WAI).

Shift into High Gear on the Web: W3C Workshop on Web and
Automotive
http://www.w3.org/2012/08/web-and-automotive/
Rome, Italy
Hosted by Intel and Sponsored by Webinos
W3C’s Open Web Platform (OWP) is driving this and other
industry transformations. The promise of the early
information superhighway is being fulfilled. Whether
tethering a driver’s smartphone or tablet to work with a
car--or embedding technology into the car itself--there’s
no need to reinvent the wheel. The Web can take you there.
Participants in this workshop will have the opportunity to
share their own perspectives, requirements, and ideas to
ensure that emerging global technology standards meet the
needs of the Web and Automotive industries.
