Dear W3C Public Newsletter Subscriber, The 2012-09-17 version of the W3C Public Newsletter is online: http://www.w3.org/News/Public/pnews-20120917 A simplified plain text version is available below. Ian Jacobs, W3C Communications Team ----------------------------------- 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.

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.

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.

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.

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.

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.

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.
