W3C Publishes HTML 5 Draft, Future of Web Content

2008-01-22: W3C today published an early draft of HTML 5, a major revision of the markup language for the Web. The HTML Working Group is creating HTML 5 to be the open, royalty-free specification for rich Web content and Web applications. "HTML is of course a very important standard," said Tim Berners-Lee, author of the first version of HTML and W3C Director. "I am glad to see that the community of developers, including browser vendors, is working together to create the best possible path for the Web." New features include APIs for drawing two-dimensional graphics and ways to embed and control audio and video content. HTML 5 helps to improve interoperability and reduce software costs by giving precise rules not only about how to handle all correct HTML documents but also how to recover from errors. Discover other new features, read the press release, and learn more about the future of HTML. (Permalink)

Call for Review: Canonical XML 1.1 Proposed Recommendation

2008-01-29: The XML Core Working Group has published the Proposed Recommendation of Canonical XML 1.1. The specification establishes a method for determining whether two documents are identical, or whether an application has not changed a document, except for transformations permitted by XML 1.0 and Namespaces in XML. Canonical XML 1.1 is a revision to Canonical XML 1.0 designed to address issues related to inheritance of attributes in the XML namespace when canonicalizing document subsets, including the requirement not to inherit xml:id, and to treat xml:base URI path processing properly. Comments are welcome through 07 March. Learn more about W3C's XML Activity. (Permalink)

Best Practice Recipes for Publishing RDF Vocabularies

2008-01-29: The Semantic Web Deployment Working Group has published the Working Draft of Best Practice Recipes for Publishing RDF Vocabularies. This document describes best practice recipes for publishing vocabularies or ontologies on the Web (in RDF Schema or OWL). Each recipe introduces general principles and an example configuration for use with an Apache HTTP server (which may be adapted to other environments). The recipes are all designed to be consistent with the architecture of the Web as currently specified. Learn more about the Semantic Web Activity. (Permalink)

SKOS Simple Knowledge Organization System Reference (First Public Working Draft)

2008-01-25: The Semantic Web Deployment Working Group has published the First Public Working Draft of SKOS Simple Knowledge Organization System Reference. This document defines the Simple Knowledge Organization System (SKOS), a common data model for sharing and linking knowledge organization systems via the Semantic Web. SKOS provides a standard, low-cost means to describe the semantic relationships between existing knowledge systems and to port those systems to the Semantic Web. SKOS also provides a lightweight, intuitive language for developing and sharing new knowledge organization systems. Learn more about the Semantic Web Activity. (Permalink)

Relationship Between Mobile Web and Web Content Accessibility (First Public Working Draft)

2008-01-22: The Mobile Web Best Practices Working Group and the WAI Education and Outreach Working Group have published the First Public Working Draft of Relationship Between Mobile Web Best Practices 1.0 and Web Content Accessibility Guidelines. See the announcement email.

The groups encourage people to start by reading Web Content Accessibility and Mobile Web: Making a Web Site Accessible Both for People with Disabilities and for Mobile Devices, which shows how design goals for accessibility and mobile access overlap. A third document, Experiences Shared by People with Disabilities and by People Using Mobile Devices, provides examples of barriers that people (without disabilities) face when interacting with Web content via mobile devices, and similar barriers for people with disabilities using desktop computers. Learn more about the Mobile Web Initiative and the Web Accessibility Initiative (WAI). (Permalink)

Document Object Model Activity Closed

2008-01-22: W3C's Document Object Model (DOM) Activity is now closed. The Document Object Model Working Group closed in the early 2004 after the completion of the DOM Level 3 Recommendations. Since then, several W3C Working Groups have taken the lead in maintaining and continuing to develop standard APIs for the Web; these include the HTML, SVG, CSS, and WebAPI Working Groups. W3C will continue to develop APIs in various Working Groups. Learn more about achievements of those participating as part of the DOM Activity on the DOM Activity Statement. (Permalink)

W3C Advisory Committee Elects TAG Participants

2008-01-22: The W3C Advisory Committee has elected Ashok Malhotra (Oracle), T.V. Raman (Google), and Henry Thompson (University of Edinburgh) to the W3C Technical Architecture Group (TAG). Continuing TAG participants are Noah Mendelsohn (IBM), David Orchard (BEA), Jonathan Rees (Science Commons), Norm Walsh (Sun), and Stuart Williams (HP), who co-Chairs the TAG with Tim Berners-Lee. The mission of the TAG is to build consensus around principles of Web architecture and to interpret and clarify these principles when necessary, to resolve issues involving general Web architecture brought to the TAG, and to help coordinate cross-technology architecture developments inside and outside W3C.

SPARQL Standard Opens Data on the Web

2008-01-15: Today, the World Wide Web Consortium made it easier to share and reuse data across application, enterprise, and community boundaries with the publication of three new Semantic Web standards for SPARQL (pronounced "sparkle"). SPARQL is the query language for the Semantic Web (see Semantic Web use cases). SPARQL queries hide the details of data management, which lowers costs and increases robustness of data integration on the Web. "Trying to use the Semantic Web without SPARQL is like trying to use a relational database without SQL," explained Tim Berners-Lee, W3C Director. There are already 14 implementations of the standard, which is comprised of three W3C Recommendations: SPARQL Query Language for RDF, SPARQL Protocol for RDF, and SPARQL Query Results XML Format. Read the press release, testimonials and learn more about the Semantic Web Activity. (Permalink)

W3C Invites Implementations of SMIL 3.0 (Candidate Recommendation)

2008-01-15: The SYMM Working Group has published the Candidate Recommendation of Synchronized Multimedia Integration Language (SMIL 3.0), an XML-based language that allows authors to create interactive multimedia presentations. Using SMIL 3.0, an author can describe the temporal behavior of a multimedia presentation, associate hyperlinks with media objects and describe the layout of the presentation on a screen. The Working Group is building a test suite help ensure interoperable implementation. Learn more about W3C work on Synchronized Multimedia (Permalink)

Service Modeling Language 1.1 Drafts

2008-01-14: The Service Modeling Language (SML) Working Group has published the third Working Drafts of Service Modeling Language, Version 1.1 and Service Modeling Language Interchange Format Version 1.1. The former defines the SML 1.1, intended to model complex services and systems, including their structure, constraints, policies, and best practices. The latter defines the SML 1.1 interchange format, designed to ensure accurate and convenient interchange of the documents that make up an SML model. Learn more about the Extensible Markup Language (XML) Activity. (Permalink)

Last Call: SMIL Timesheets 1.0

2008-01-10: The SYMM Working Group has published the Last Call Working Draft of SMIL Timesheets 1.0; this is also the First Public Working Draft. This document defines an XML timing language that makes SMIL 3.0 element and attribute timing control available to a wide range of other XML languages. This language allows SMIL timing to be integrated into a wide variety of a-temporal languages, even when several such languages are combined in a compound document. Because of its similarity with external style and positioning descriptions in the Cascading Style Sheet (CSS) language, this functionality has been termed SMIL Timesheets. Comments are welcome through 15 February. Learn more about W3C work on Synchronized Multimedia. (Permalink)

W3C Welcomes Review of Three OWL 1.1 First Public Drafts

2008-01-08: The OWL Working Group has published the First Public Working Draft of three Web Ontology Language (OWL) 1.1 specifications: Structural Specification and Functional-Style Syntax, Model-Theoretic Semantics, and Mapping to RDF Graphs. OWL is used to define Semantic Web vocabularies. Together, these new specifications extend the W3C OWL Web Ontology Language 1.0 with a small but useful set of features that have been requested by users, for which effective reasoning algorithms are now available, and that OWL tool developers are willing to support. The three specifications cover, respectively, the syntax, semantics, and mapping to RDF of OWL 1.1 ontologies. Learn more about the W3C Semantic Web Activity. (Permalink)

XHTML Access Module; Comments Welcome

2008-01-07: The XHTML2 Working Group has published the First Public Working Draft of XHTML Access Module. This document is intended to help make XHTML-family markup languages more effective at supporting the needs of the accessibility community. It does so by providing a generic mechanism for defining the relationship between document components and well-known accessibility taxonomies. Learn more about the HTML Activity. (Permalink)
