W3C Invites Implementations of DOM Parsing and Serialization

The Web Applications Working Group invites implementation of the Candidate Recommendation of DOM Parsing and Serialization. This specification defines various APIs for programmatic access to HTML and generic XML parsers by web applications for use in parsing and serializing DOM nodes.

The group also published a Working Draft of Shadow DOM. This specification describes a method of combining multiple DOM trees into one hierarchy and how these trees interact with each other within a document, thus enabling better composition of the DOM.

Last Call: HTML5

The HTML Working Group has published a Last Call Working Draft of HTML5. This specification defines the 5th major revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, new features are introduced to help Web application authors, new elements are introduced based on research into prevailing authoring practices, and special attention has been given to defining clear conformance criteria for user agents in an effort to improve interoperability. Comments are welcome through 15 July 2014.

The group also published a Working Draft of HTML 5.1. HTML was primarily designed as a language for semantically describing scientific documents, although its general design and adaptations over the years have enabled it to be used to describe a number of other types of documents. The main area that has not been adequately addressed by HTML is a vague subject referred to as Web Applications. This standard attempts to rectify this, while at the same time updating the HTML language to address issues raised in the past few years.

Core Accessibility API Mappings 1.1 (Core-AAM) First Public Working Draft and WAI-ARIA 1.1 updated Working Draft

The Protocols and Formats Working Group today published a First Public Working Draft of Core Accessibility API Mappings 1.1 (Core-AAM), which supports the updated Working Draft of Accessible Rich Internet Applications (WAI-ARIA) 1.1. WAI-ARIA provides an ontology of roles, states, and properties that define accessible user interface elements. WAI-ARIA is designed to improve the accessibility and interoperability of web content, particularly web applications. Core-AAM describes how user agents should expose semantics of content languages to accessibility APIs across multiple content technologies (including much of WAI-ARIA). Core-AAM serves as the basis for other specifications to extend the mappings to specific technologies.

Three Specifications Published by the Web Applications Working Group

The Web Applications Working Group has published three documents today:

  • A First Public Working Draft of DOM Level 3 KeyboardEvent key Values. This specification defines the values for the KeyboardEvent.key attribute, which is defined as part of the Document Object Model (DOM) Level 3 Events Specification. The key attribute contains information about the character generated by the key event.
  • A First Public Working Draft of DOM Level 3 KeyboardEvent code Values. This specification defines the values for the KeyboardEvent.code attribute, which is defined as part of the Document Object Model (DOM) Level 3 Events Specification. The code value contains information about the key event that can use used identify the physical key being pressed by the user.
  • A Working Draft of UI Events. This specification extends the events and features defined in DOM Events Level 3.

Workshop Report: Linking Geospatial Data

Today the W3C announced the final report from the Linking Geospatial Data workshop that was held in London 5 – 6 March 2014.

The report contains a summary of each of the major themes discussed and conclusions arising from them. The workshop was supported by the Open Geospatial Consortium (OGC), Google, the UK mapping agency Ordnance Survey and the UK government. W3C’s participation was funded by the EU-funded SmartOpenData project.

Participants included many geospatial experts from both the government and private sectors, and the presented papers focused on integrating geospatial information systems with the Web of Data. Although carefully advertised so as not to promote Linked Data to the exclusion of other methods, this emerged strongly as the preferred technology to enable that integration.

The Workshop report identifies several themes that recurred throughout the discussion. A consensus of the participants was that joint work between W3C and OGC should be pursued to address the needs identified in these themes.

Web Animations 1.0 Draft Published

The Cascading Style Sheets (CSS) Working Group and the SVG Working Group have published a Working Draft of Web Animations 1.0. This specification defines a model for synchronization and timing of changes to the presentation of a Web page. This specification also defines an application programming interface for interacting with this model and it is expected that further specifications will define declarative means for exposing these features. Learn more about the Style Activity and the Graphics Activity.

First Public Working Draft: Media Queries Level 4

The Cascading Style Sheets (CSS) Working Group has published a Working Draft of Media Queries Level 4. Media Queries allow authors to test and query values or features of the user agent or display device, independent of the document being rendered. They are used in the CSS @media rule to conditionally apply styles to a document, and in various other contexts and languages, such as HTML and Javascript. Media Queries Level 4 describes the mechanism and syntax of media queries, media types, and media features. The specification extends and supersedes the features defined in Media Queries Level 3. 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.

First Public Working Draft: Data on the Web Best Practices Use Cases and Requirements

The Data on the Web Best Practices Working Group has published a First Public Working Draft of Data on the Web Best Practices Use Cases & Requirements. This document lists some use cases, compiled by the Data on the Web Best Practices Working Group, that represent scenarios of how data is commonly published on the Web and how it is used. This document also provides a set of requirements derived from these use cases that have been used to guide the development of the set of Data on the Web Best Practices and the development of two new vocabularies: Quality and Granularity Description Vocabulary and Data Usage Description Vocabulary.

Last Call Working Draft of Encoding, and two Authoring HTML Notes Published

The Internationalization Working Group has published three documents today:

  • A Last Call Working Draft of Encoding. While encodings have been defined to some extent, implementations have not always implemented them in the same way, have not always used the same labels, and often differ in dealing with undefined and former proprietary areas of encodings. This specification attempts to fill those gaps so that new implementations do not have to reverse engineer encoding implementations of the market leaders and existing implementations can converge. Comments are welcome through 1 July 2014.
  • A Group Note of Authoring HTML: Handling Right-to-left Scripts. This document provides advice to content authors using HTML markup and CSS style sheets about how to create pages for languages that use right-to-left scripts, such as Arabic, Hebrew, Persian, Thaana, Urdu, etc. It explains how to create content in right-to-left scripts that builds on but goes beyond the Unicode bidirectional algorithm, as well as how to prepare content for localization into right-to-left scripts.
  • A Group Note of Authoring HTML: Language declarations. Specifying the language of content is useful for a wide number of applications, from linguistically-sensitive searching to applying language-specific display properties. In some cases the potential applications for language information are still waiting for implementations to catch up, whereas in others it is a necessity today. Adding markup for language information to content is something that can and should be done as content is first developed. If not, it will be much more difficult to take advantage of any future developments.

First Public Working Draft: Non-element Selectors Module Level 1

The Cascading Style Sheets (CSS) Working Group has published a Working Draft of Non-element Selectors Module Level 1. This specification extends Selectors Level 4 and allows selecting other kinds of document nodes than elements. This is useful when selectors are used as a general document query language. Non-element Selectors are not intended to be used in CSS, but only as a separate query language in other host environments. 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.
