W3C Invites Implementations of W3C XML Schema Definition Language (XSD) 1.1

2009-05-04: The XML Schema Working Group invites implementation of the Candidate Recommendation of XML Schema Definition Language (XSD) 1.1. The specification consists of Part 1: Structures and Part 2: Datatypes. XSD provides tools for describing the structure of XML content and constraining the contents of XML documents. Part 2 provides tools for defining datatypes (dates, times, numbers, strings, etc.) to be used in XML Schemas as well as other XML specifications. Information about changes to structures and changes to datatypes since XML Schema 1.0 is available. Learn more about the Extensible Markup Language (XML) Activity. (Permalink)

W3C Organizes Workshop on using Ink in Multimodal Applications

2009-05-01: W3C invites people to participate in a Workshop on using Ink in Multimodal Applications within the W3C's Multimodal Architecture and Interfaces on 10-11 July 2009 in Grand Bend, Ontario (Canada), hosted by the University of Western Ontario. The goal of the Workshop is to help the Multimodal Interaction Working Group integrate handwriting modality components (Ink Modality Components) into the MMI Architecture and clarify what should be added to the Multimodal specifications to enable applications to adapt to various modality combinations including Ink. Attendees will discuss requirements for changes, extensions and additions to Ink standards especially in Multimodal Applications developed based on the W3C's MMI Architecture as a means of making InkML more useful in current and emerging markets. Position papers are due 1 June 2009. Read about the Ink Markup Language (InkML) and W3C's Multimodal Interaction Activity. (Permalink)

Three First Drafts of SVG Modules Published

2009-04-30: The Scalable Vector Graphics (SVG) Working Group published three first public drafts today. SVG is a language for describing vector graphics, but it is typically rendered to a display or some form of print medium. The first new publication, SVG Compositing, adds support for raster and vector objects to be combined to produce eye catching effects via advanced alpha compositing, masks, and clipping paths. The other specifications are for SVG Referenced Parameter Variables: Part 1: Primer and Part 2: Language. The Referenced Parameter Variables specification provides a declarative way to incorporate parameter values into SVG content. Often, users may wish to create a single resource, and reuse it several times with specified variations, and this specification provides a means to do so without the use of script. Learn more about the Graphics Activity. (Permalink)

Last Call: Widgets 1.0: Digital Signatures; Widgets Requirements Updated

2009-04-30: The Web Applications Working Group has published the Last Call Working Draft of Widgets 1.0: Digital Signatures. This document defines a profile of the XML Signature Syntax and Processing 1.1 specification to allow a widget package to be digitally signed. Widget authors and distributors can digitally sign widgets as a mechanism to ensure continuity of authorship and distributorship. A user agent can use the digital signature to verify the integrity of the widget package and to confirm the signing key(s). Comments are welcome through 01 June. The Working Group also published an updated Working Draft of Widgets 1.0: Requirements. Learn more about the Rich Web Client Activity. (Permalink)

First Draft of Use cases and requirements for Media Fragments

2009-04-30: The Media Fragments Working Group has published the First Public Working Draft of Use cases and requirements for Media Fragments. The aim of this specification is to enhance the Web infrastructure for supporting the addressing and retrieval of subparts of time-based Web resources. Example uses are the sharing of such fragment URIs with friends via email, the automated creation of such fragment URIs in a search engine interface, or the annotation of media fragments with RDF. This specification will help make video a first-class citizen of the World Wide Web. In addition to describing use cases for the Media Fragments 1.0 specification, this document discusses syntax and processing of media fragment URIs, and offers survey of technologies that address multimedia fragments. Learn more about the Video in the Web Activity. (Permalink)
