The Model-Based User Interfaces Working Group has published the First Public Working Draft of MBUI - Task Models. Task models are useful when designing and developing interactive systems. They describe the logical activities that have to be carried out in order to reach the user’s goals. This document covers the specification of Task Models, with a meta-model expressed in UML, and an XML Schema that can be used as the basis for interchange of Task Models between different user interface development tools.

The Audio Working Group has published a Working Draft of Web Audio API. This specification describes a high-level JavaScript API for processing and synthesizing audio in web applications. The primary paradigm is of an audio routing graph, where a number of AudioNode objects are connected together to define the overall audio rendering. The actual processing will primarily take place in the underlying implementation (typically optimized Assembly / C / C++ code), but direct JavaScript processing and synthesis is also supported. This API is designed to be used in conjunction with other APIs and elements on the web platform, notably: XMLHttpRequest (using the responseType and response attributes). For games and interactive applications, it is anticipated to be used with the canvas 2D and WebGL 3D graphics APIs. Learn more about the Rich Web Client Activity.

The MultilingualWeb-LT Working Group has published a Working Draft of Internationalization Tag Set (ITS) Version 2.0. This document defines data categories and their implementation as a set of elements and attributes called the Internationalization Tag Set (ITS) 2.0. ITS 2.0 is the successor of ITS 1.0; it is designed to foster the creation of multilingual Web content, focusing on HTML5, XML based formats in general, and to leverage localization workflows based on the XML Localization Interchange File Format (XLIFF). In addition to HTML5 and XML, algorithms to convert ITS attributes to RDFa and NIF are provided. Learn more about the Internationalization Activity.
