The CSS Working Group and the SVG Working Group invite implementations of the Candidate Recommendation of Geometry Interfaces Module Level 1. This specification provides basic geometric interfaces to represent points, rectangles, quadrilaterals and transformation matrices that can be used by other modules or specifications. Learn more about the Style Activity and the Graphics Activity.
The CSS Working Group and the SVG Working Group have published a Working Draft of Filter Effects Module Level 1. Filter effects are a way of processing an element’s rendering before it is displayed in the document. Typically, rendering an element via CSS or SVG can conceptually be described as if the element, including its children, are drawn into a buffer (such as a raster image) and then that buffer is composited into the elements parent. Filters apply an effect before the compositing stage. Examples of such effects are blurring, changing color intensity and warping the image. Although originally designed for use in SVG, filter effects are a set of operations to apply on an image buffer and therefore can be applied to nearly any presentational environment, including CSS. They are triggered by a style instruction (the filter property). This specification describes filters in a manner that allows them to be used in content styled by CSS, such as HTML and SVG. It also defines a CSS property value function that produces a CSS value. Learn more about the Style Activity and the Graphics Activity.
The Tracking Protection Working Group has published a Working Draft of Tracking Compliance and Scope. This specification defines the meaning of a Do Not Track (DNT) preference and sets out practices for websites to comply with this preference. Learn more about the Privacy Activity.
W3C has published the October 2014 edition of Standards for Web Applications on Mobile, an overview of the various technologies developed in W3C that increase the capabilities of Web applications, and how they apply more specifically to the mobile context.
A deliverable of the HTML5Apps project, this edition includes changes and additions since July 2014, notably emerging work such as the Second Screen Presentation Working Group API to request display of content on an external screen, a draft API from the Web Bluetooth Community Group, Device APIs Working Group work on a generic pattern for sensors APIs, as well as work on an API to manage permissions across other APIs. Learn more about the Web and Mobile Interest Group.
The Web Applications Working Group has published a Proposed Recommendation of Indexed Database API. This document defines APIs for a database of records holding simple values and hierarchical objects. Each record consists of a key and some value. Moreover, the database maintains indexes over records it stores. An application developer directly uses an API to locate records either by their key or by using an index. A query language can be layered on this API. An indexed database can be implemented using a persistent B-tree data structure. Comments are welcome through 18 December. Learn more about the Rich Web Client Activity.
The Web Applications Working Group has published a Working Draft of Service Workers. This specification describes a method that enables applications to take advantage of persistent background processing, including hooks to enable bootstrapping of web applications while offline. The core of this system is an event-driven Web Worker, which responds to events dispatched from documents and other sources. A system for managing installation, versions, and upgrades is provided. The service worker is a generic entry point for event-driven background processing in the Web Platform that is extensible by other specifications. Learn more about the Rich Web Client Activity.
Registration is now open for the online symposium on Accessible Way-Finding Using Web Technologies to be held on 3 December 2014. Researchers, practitioners, users with disabilities, and others are invited to explore new and on-going research and development on accessible way-finding using web technologies. Symposium participants will examine different technologies, applications, concepts, and solutions that help people with disabilities orient themselves, explore, and navigate through the physical world. For details and registration, see the Accessible Way-Finding Using Web Technologies Symposium page. Learn more about the Web Accessibility Initiative (WAI).
The Pointer Events Working Group has published a Last Call Working Draft of Pointer Events. This document defines events and related interfaces for handling hardware agnostic pointer input from devices like a mouse, pen, or touchscreen. For compatibility with existing mouse based content, this specification also describes a mapping to fire Mouse Events for pointer device types other than mouse. Comments are welcome through 4 December. Learn more about the Rich Web Client Activity.
The Web Application Security Working Group has published a Last Call Working Draft of Mixed Content. This specification describes how user agents should handle rendering and execution of content loaded over unencrypted or unauthenticated connections in the context of an encrypted and authenticated document. Comments are welcome through 11 December. Learn more about the Security Activity.
The Timed Text Working Group has published a First Public Working Draft of WebVTT: The Web Video Text Tracks Format. This specification defines WebVTT, the Web Video Text Tracks format. Its main use is for marking up external text track resources in connection with the HTML element. WebVTT files provide captions or subtitles for video content, and also text video descriptions, chapters for content navigation, and more generally any form of metadata that is time-aligned with audio or video content. Learn more about the Video in the Web Activity.
