The Web Applications Working Group has published the First Public Working Draft of HTML5 Web Messaging. This specification defines two mechanisms for communicating between browsing contexts in HTML documents. Cross document messaging allows documents to communicate with each other regardless of their source domain, in a way designed to not enable cross-site scripting attacks. Channel messaging allows independent pieces of code (e.g. running in different browsing contexts) to communicate directly. Learn more about the Rich Web Client Activity.

The Timed Text Working Group has published a W3C Recommendation of Timed Text Markup Language (TTML) 1.0. TTML 1.0 provides a standardized representation of a particular subset of textual information with which stylistic, layout, and timing semantics are associated by an author or an authoring system for the purpose of interchange and potential presentation. Learn more about the Video in the Web Activity.

The RDB2RDF Working Group has published the First Public Working Draft of A Direct Mapping of Relational Data to RDF. The need to share data with collaborators motivates custodians and users of relational databases (RDB) to expose relational data on the Web of Data. This document defines a direct mapping from relational data to RDF. This definition provides extension points for refinements within and outside of this document. Learn more about the Semantic Web Activity.

The WebFonts Working Group has published a Last Call Working Draft of WOFF File Format 1.0. This document specifies a simple compressed file format for fonts, designed primarily for use on the Web and known as WOFF (Web Open Font Format). WOFF provides lightweight, easy-to-implement compression of font data, suitable for use with CSS style sheets. WOFF is a container format or "wrapper" for font data in already-existing formats rather than an actual font format in its own right. Comments are welcome through 14 December.
