The Web Performance Working Group has published two Proposed Recommendations and invites implementation of the Candidate Recommendation today:

• A Proposed Recommendations of User Timing, which defines an interface to help Web developers measure the performance of their applications by giving them access to high precision timestamps. Comments are welcome through 28 November.
• A Proposed Recommendation of Performance Timeline. This specification defines an unified interface to store and retrieve performance metric data. This specification does not cover individual performance metric interfaces. Comments are welcome through 28 November.
• A Candidate Recommendation of Timing control for script-based animations. This document defines an API web page authors can use to write script-based animations where the user agent is in control of limiting the update rate of the animation. The user agent is in a better position to determine the ideal animation rate based on whether the page is currently in a foreground or background tab, what the current load on the CPU is, and so on. Using this API should therefore result in more appropriate utilization of the CPU by the browser.

The Web Events Working Group has published a Group Note of Touch Events Extensions. This document defines extensions to the Touch Events specification that have been implemented by one or more browsers. This document is no longer being developed. Learn more about the Rich Web Client Activity.

The Linked Data Platform (LDP) Working Group has published a Working Draft of Linked Data Platform Use Cases and Requirements. To foster the development of the Linked Data Platform specification, this document includes a set of user stories, use cases, scenarios and requirements that motivate a simple read-write Linked Data architecture, based on HTTP access to web resources that describe their state using RDF. The starting point for the development of these use cases is a collection of user stories that provide realistic examples describing how people may use read-write Linked Data. The use cases themselves are captured in a narrative style that describes a behavior, or set of behaviors based on, and using scenarios from, these user stories. The aim throughout has been to avoid details of protocol (specifically the HTTP protocol), and use of any specific vocabulary that might be introduced by the LDP specification.

The HTML Working Group has update two Working Drafts and a Working Group Note today:

• A Working Draft of HTML 5.1, which defines the 5th major version, first minor revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, new features continue to be introduced to help Web application authors, new elements continue to be introduced based on research into prevailing authoring practices, and special attention continues to be given to defining clear conformance criteria for user agents in an effort to improve interoperability.
• A Working Draft of HTML Canvas 2D Context, Level 2. This specification defines the 2D Context for the HTML canvas element. The 2D Context provides objects, methods, and properties to draw and manipulate graphics on a canvas drawing surface.
• A Group Note of HTML Microdata, which defines the HTML microdata mechanism. This mechanism allows machine-readable data to be embedded in HTML documents in an easy-to-write manner, with an unambiguous parsing model. It is compatible with numerous other data formats including RDF and JSON.
