Dataset Descriptions: HCLS Community Profile Note Published

The Semantic Web Health Care and Life Sciences Interest Group has published a Group Note of Dataset Descriptions: HCLS Community Profile. Access to consistent, high-quality metadata is critical to finding, understanding, and reusing scientific data. This document describes a consensus among participating stakeholders in the Health Care and the Life Sciences domain on the description of datasets using the Resource Description Framework (RDF). This specification meets key functional requirements, reuses existing vocabularies to the extent that it is possible, and addresses elements of data description, versioning, provenance, discovery, exchange, query, and retrieval.

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. This 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 11 June.

New version of WAI-ARIA Authoring Practices; Updates to WAI-ARIA 1.1 and Core Accessibility API Mappings

The Protocols and Formats Working Group has published a First Public Working Draft of WAI-ARIA Authoring Practices 1.1 and updated Working Drafts of Accessible Rich Internet Applications (WAI-ARIA) 1.1 and Core Accessibility API Mappings (Core-AAM) 1.1.

WAI-ARIA Authoring Practices recommends approaches to help web application developers make widgets, navigation, and behaviors accessible using WAI-ARIA roles, states, and properties. This new version has been substantially reworked in order to provide guidance specific to WAI-ARIA 1.1. WAI-ARIA provides an ontology of roles, states, and properties that define accessible user interface elements. It 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) and serves as the basis for other specifications to extend the mappings to specific technologies. Learn more from the call for review e-mail and read about the Web Accessibility Initiative (WAI).

W3C Celebrates 20 Years in Europe

W3C 20 Europe logoWhile the Web was born in Europe in 1989, today W3C celebrates twenty years of work accomplished by European stakeholders within W3C, the organization that helps keep the Web open, free and accessible to all.

The W3C European host was established in Sophia Antipolis, France, in April 1995. The first draft of the WCAG guidelines, the promise of the mobile Web and more recently the Web payments work were all initiated by the W3C Europe staff. Sir Tim Berners-Lee, W3C director and Web inventor, together with a panel of luminaries, will share his vision of the future Web.

The event is supported by Inria and ERCIM, former and current W3C Europe hosts. We also thank Hachette Livre for its generous support of W3CEurope@20.

IndieUI: Events and IndieUI: User Context Updated Working Drafts Published

The IndieUI Working Group has published a Working Draft of IndieUI: Events 1.0 – Events for User Interface Independence and IndieUI: User Context 1.0 – Contextual Information for User Interface Independence. These drafts include a reduction in scope for the 1.0 version of Events, and minor property and interface changes in User Context. IndieUI: Events defines a way for different user interactions to be translated into simple events and communicated to Web applications. IndieUI: User Context defines a set of preferences that users can choose to expose to web applications, and an API for user agents to access the preferences and listen for changes. Both IndieUI specifications will make it easier for Web applications to work in a wide range of contexts — different devices (such as mobile phones and tablets), different assistive technologies (AT), different user needs. With these technologies, Web application developers will have a uniform way to design applications that work for multiple devices and contexts. The IndieUI Working Group is currently exploring moving this work to other Working Groups; however, comments on these drafts are still welcomed, preferably by 29 May 2015. Learn more from the IndieUI Overview; and read about the Web Accessibility Initiative (WAI).

Language Tags and Locale Identifiers for the World Wide Web Draft Published

The Internationalization Working Group has published a Working Draft of Language Tags and Locale Identifiers for the World Wide Web. This document describes the best practices for identifying or selecting the language of content as well as the the locale preferences used to process or display data values and other information on the Web. It describes how document formats, specifications, and implementations should handle language tags, as well as extensions to language tags that describe the cultural or linguistic preferences referred to in internationalization as a “locale”.
