Last Call: CSS Flexible Box Layout Module Level 1

The Cascading Style Sheets (CSS) Working Group has published a Last Call Working Draft of CSS Flexible Box Layout Module Level 1. The specification describes a CSS box model optimized for user interface design. In the flex layout model, the children of a flex container can be laid out in any direction, and can “flex” their sizes, either growing to fill unused space or shrinking to avoid overflowing the parent. Both horizontal and vertical alignment of the children can be easily manipulated. Nesting of these boxes (horizontal inside vertical, or vertical inside horizontal) can be used to build layouts in two dimensions. Comments are welcome through 25 October.

Document Object Model (DOM) Level 3 Events Specification Draft Published

The Web Applications Working Group has published a Working Draft of Document Object Model (DOM) Level 3 Events Specification. DOM Events is designed with two main goals. The first goal is the design of an event system which allows registration of event listeners and describes event flow through a tree structure. Additionally, the specification will provide standard modules of events for user interface control and document mutation notifications, including defined contextual information for each of these event modules. The second goal of DOM Events is to provide a common subset of the current event systems used in existing browsers. This is intended to foster interoperability of existing scripts and content.

Upcoming Workshop: Privacy and User–Centric Controls

Today the W3C announced a Workshop on Privacy and User–Centric Controls, on 20–21 November 2014, Berlin, Germany to investigate strategies toward better privacy protection on the Web, especially for mobile devices.

The Workshop focus will be on users: user experience, user behavior and how we can offer controls that provide the necessary transparency of privacy-affecting interactions. We will also discuss how developers can meet users’ privacy needs on the Web, including what APIs are necessary for user privacy.

Sample Workshop topics include (but are not limited to):

  • Improving the UI for stateful services, overview of states
  • Defaults for expiration of stateful situations
  • How to convey state information to the User
  • How to deal with logging and how to provide interfaces for logged data
  • Requirements for private browsing on mobile
  • A privacy ontology for mobile apps and their use of personal data
  • The value of privacy in paradigms for mobile UI
  • Selective release of personal information to apps
  • Controlling the geo-location interfaces, including UI challenges
  • Enforcing data expiry

W3C membership is not required to participate. There is no cost to participate and the event is open to all. All participants are required to submit a position paper or statement of interest by 10 October 2014. Learn more how to participate.

Geometry Interfaces Module Level 1 Draft Published

The the CSS Working Group and the SVG Working Group jointly published a Working Draft 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. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. Learn more about the Style Activity and the Graphics Activity.

Last Call: XQuery and XPath Full Text 3.0; XQuery Scripting Extension 1.0 Note Published

The XML Query Working Group has published a Last Call Working Draft of XQuery and XPath Full Text 3.0. This document defines the syntax and formal semantics of XQuery and XPath Full Text 3.0, which is a language that extends XQuery 3.0 and XPath 3.0 with full-text search capabilities. Comments are welcome through 17 October 2014.

In addition, the XML Query Working Group and the XSLT Working Group jointly published a Group Note of XQuery Scripting Extension 1.0. This specification defines an extension to XQuery 1.0 and XQuery Update Facility. Expressions can be evaluated in a specific order, with later expressions seeing the effects of the expressions that came before them. This specification introduces several new kinds of expression, including the apply, assignment, while, and exit expression, and a block expression with local variable declarations.
