W3C

The Web Platform Working Group has published a W3C Recommendation of Web Storage (Second Edition). This specification defines an API for persistent data storage of key-value pair data in Web clients. It introduces two related mechanisms, similar to HTTP session cookies, for storing name-value pairs on the client side. The first mechanism is designed for scenarios where the user is carrying out a single transaction, but could be carrying out multiple transactions in different windows at the same time. The second mechanism is designed for storage that spans multiple windows, and lasts beyond the current session.

The Cascading Style Sheets (CSS) Working Group has published a Working Draft of Cascading Style Sheets Level 2 Revision 2 (CSS 2.2) Specification. This specification defines Cascading Style Sheets level 2. CSS is a style sheet language that allows authors and users to attach style (e.g. fonts and spacing) to structured documents (e.g. HTML documents and XML applications). By separating the presentation style of documents from the content of documents, CSS simplifies Web authoring and site maintenance.

The Web Performance Working Group has published a Working Draft of Reporting API 1. This document defines a generic reporting framework which allows web developers to associate a set of named reporting endpoints with an origin. Various platform features (like Content Security Policy, Network Error Reporting, and others) will use these endpoints to deliver feature-specific reports in a consistent manner.

The Web Cryptography Working Group has published a Group Note of WebCrypto Key Discovery. This note describes a JavaScript API for discovering named, origin-specific pre-provisioned cryptographic keys for use with the Web Cryptography API. Pre-provisioned keys are keys which have been made available to the UA by means other than the generation, derivation, importation and unwrapping functions of the Web Cryptography API. Origin-specific keys are keys that are available only to a specified origin. Named keys are identified by a name assumed to be known to the origin in question and provisioned with the key itself. This note concerns only keys which have all three of these properties.

The Device APIs Working Group has published a Proposed Recommendation of Battery Status API. The Battery Status API specification defines a means for web developers to programmatically determine the battery status of the hosting device. Without knowing the battery status of a device, a web developer must design the web application with an assumption of sufficient battery level for the task at hand. This means the battery of a device may exhaust faster than desired because web developers are unable to make decisions based on the battery status. This specification defines an API that provides information about the battery status of the hosting device. Comments are welcome through 29 April.
