SVG Integration Draft Published

The SVG Working Group has published a Working Draft of SVG Integration. This specification details requirements on how SVG documents must be processed when used in various contexts, such as CSS background images, HTML ‘iframe’ elements, and so on. These requirements include which features are restricted or disabled, such as scripting and animation. A number of referencing modes are defined, which other specifications that allow the embedding or referencing of SVG documents can normatively reference. Learn more about the Graphics Activity.

XQuery 3.0, XPath 3.0, XQueryX 3.0, XDM 3.0, Serialization 3.0, Functions and Operators 3.0 are now W3C Recommendations

The XML Query Working Group published XQuery 3.0: An XML Query Language, along with XQueryX, an XML representation for XQuery, both as W3C Recommendations, as well as the XQuery 3.0 Use Cases and Requirements as final Working Group Notes. XQuery extends the XPath language to provide efficient search and manipulation of information represented as trees from a variety of sources.

The XML Query Working Group and XSLT Working Group also jointly published W3C Recommendations of XML Path Language (XPath) 3.0, a widely-used language for searching and pointing into tree-based structures, together with XQuery and XPath Data Model 3.0 which defines those structures, XPath and XQuery Functions and Operators 3.0 which provides facilities for use in XPath, XQuery, XSLT and a number of other languages, and finally the XSLT and XQuery Serialization 3.0 specification giving a way to turn values and XDM instances into text, HTML or XML.

XML Entity Definitions for Characters (2nd Edition), and Mathematical Markup Language (MathML) Version 3.0 2nd Edition are W3C Recommendations

The Math Working Group has published two W3C Recommendations today:

  • XML Entity Definitions for Characters (2nd Edition). This document defines several sets of names, so that to each name is assigned a Unicode character or sequence of characters. Each of these sets is expressed as a file of XML entity declarations.
  • Mathematical Markup Language (MathML) Version 3.0 2nd Edition. This specification defines the Mathematical Markup Language, or MathML. MathML is a markup language for describing mathematical notation and capturing both its structure and content. The goal of MathML is to enable mathematics to be served, received, and processed on the World Wide Web, just as HTML has enabled this functionality for text.

W3C Track at WWW2014 in Seoul

WWW2014 logoAt this year’s 23rd International World Wide Web Conference (WWW2014), W3C organizes W3C tutorial and W3C tracks where conference participants are invited to learn from, meet and discuss with our team of experts. With the conference located in Korea, the W3C track sessions also cater specifically for the Korean industry. The presentations and discussions are about Web Cryptography, Web Publishing, Web & TV, and Web accessibility. W3C and Tim Berners-Lee will dedicate the last W3C track session to the Web 25th birthday; ideas for the Web came and are still coming from the WWW conference series, thus we will give the floor to the audience and ask conference participants how they see the Web evolving in the next 25 years. So, come and discuss!

MBUI: Abstract User Interface Models, and Task Models Notes Published

The Model-Based User Interfaces Working Group has published two Group Notes today:

  • MBUI – Abstract User Interface Models. Model-Based User Interface Design facilitates interchange of designs through a layered approach that separates out different levels of abstraction in user interface design. This document covers the specification of Abstract User Interface Models, by defining its semantics through a meta-model, and an interchange syntax (expressed as XML Schema) for exchanging Abstract User Interface Models between different user interface development environments.
  • 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.

CSS Line Grid Module Level 1, and CSS Scoping Module Level 1 Drafts Published

The Cascading Style Sheets (CSS) Working Group has published two Working Drafts today:

  • CSS Line Grid Module Level 1. This module contains CSS features for aligning content to a baseline grid.
  • CSS Scoping Module Level 1. This specification defines various scoping/encapsulation mechanisms for CSS, including scoped styles and the @scope rule, Shadow DOM selectors, and page/region-based styling.

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.

Review of apps that use network information Note Published

The Web and Mobile Interest Group has published a Group Note of Review of apps that use network information. The web platform currently lacks a means of exposing network-related information to web applications. Network information includes, but is not limited to, the type of network connection currently in use by a device (e.g., cellular, Wi-Fi, etc.). It can also include information such as the system notifying the application when the type of connection changes from one type to another (e.g., from cellular to Wi-Fi).

Vocabularies for EmotionML Note Published

The Multimodal Interaction Working Group has published a Group Note of Vocabularies for EmotionML. This document provides a list of emotion vocabularies that can be used with EmotionML to represent emotions and related states. EmotionML provides mechanisms to represent emotions in terms of scientifically valid descriptors: categories, dimensions, appraisals, and action tendencies. Given the lack of agreement in the community, EmotionML does not provide a single vocabulary of emotion terms, but gives users a choice to select the most suitable emotion vocabulary in their annotations. In order to promote interoperability, publicly defined vocabularies should be used where possible and reasonable from the point of view of the target application. The present document provides a number of emotion vocabularies that can be used for this purpose. Learn more about the Multimodal Interaction Activity.

CSV on the Web Use Cases and Requirements, and Model for Tabular Data and Metadata Published

The CSV on the Web Working Group published two First Public Working Drafts today:

  • The CSV on the Web: Use Cases and Requirements collects use cases that are at the basis of the work of the Working Group. A large percentage of the data published on the Web is tabular data, commonly published as comma separated values (CSV) files. The Working Group aim to specify technologies that provide greater interoperability for data dependent applications on the Web when working with tabular datasets comprising single or multiple files using CSV, or similar, format. This document lists a first set of use cases compiled by the Working Group that are considered representative of how tabular data is commonly used within data dependent applications. The use cases observe existing common practice undertaken when working with tabular data, often illustrating shortcomings or limitations of existing formats or technologies. This document also provides a first set of requirements derived from these use cases that have been used to guide the specification design.
  • The Model for Tabular Data and Metadata on the Web outlines a basic data model, or infoset, for tabular data and metadata about that tabular data. The document contains first drafts for various methods of locating metadata: one of the output the Working Group is chartered for is to produce a metadata vocabulary and standard method(s) to find such metadata. It also contains some non-normative information about a best practice syntax for tabular data, for mapping into that data model, to contribute to the standardisation of CSV syntax by IETF (as a possible update of RFC4180).

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. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. Comments are welcome through 22 April 2014.
