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, semantcs, and mapping to RDF of OWL 1.1 ontologies. Learn more about the W3C Semantic Web Activity. (Permalink)
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)
2008-01-07: The XHTML2 Working Group has published the First Public Working Draft of XHTML Access Module.

2007-12-21: The Web API Working Group has published the Last Call Working Draft of Selectors API. Selectors, which are widely used in CSS, are patterns that match against elements in a tree structure. The Selectors API specification defines methods for retrieving Element nodes from the Document Object Model (DOM) by matching against a group of selectors. Comments are welcome through 06 January 2008. The Working Group has also published a Working Draft of DOM Level 3 Events, a generic platform- and language-neutral event system which allows registration of event handlers, describes event flow through a tree structure, and provides basic contextual information for each event. Learn more about the Rich Web Client Activity. (Permalink)
2007-12-21: The Ubiquitous Web Applications Working Group has published the Candidate Recommendation of Delivery Context: Client Interfaces (DCCI) 1.0. This document defines platform and language neutral programming interfaces that provide Web applications access to a hierarchy of dynamic properties representing device capabilities, configurations, user preferences and environmental conditions. In addition, the Working Group has published the First Public Working Draft of Delivery Context Ontology, which provides a formal model for the delivery context which other specifications can reference normatively.

2007-12-19: The Efficient XML Interchange (EXI) Working Group has published three documents: First Public Working Drafts of EXI Best Practices and EXI Primer, as well as a Working Draft of EXI Format 1.0. EXI is a very compact representation for the Extensible Markup Language (XML) Information Set that is intended to simultaneously optimize performance and the utilization of computational resources. Using a relatively simple algorithm, which is amenable to fast and compact implementation, and a small set of data types, it reliably produces efficient encodings of XML event streams. The primer and best practices documents complement the format specification. The best practices document also presents information suitable for the general reader interested in EXI's intended role in the expanding Web.

2007-12-17: The Semantic Web Education and Outreach Interest Group has released a first Working Draft of a document explaining the effective use of URIs to enable the growth of the Semantic Web. URIs (Uniform Resource Identifiers) more simply called "Web addresses" are at the heart of the Web and also of the Semantic Web. Cool URIs for the Semantic Web discusses two strategies for choosing URIs for the Semantic Web, gives pointers to several Web sites that use these solutions, and briefly discusses why several other alternatives are less effective. Comments on this draft are requested by 21 January, to be integrated into a final document at the end of the Group's charter. Learn more about the Semantic Web Activity. (Permalink)
2007-12-17: The Mobile Web Initiative Device Description Working Group has published the Group Note of Device Description Repository Requirements 1.0. This document describes the use cases for a Device Description Repository (DDR). Each use case is analyzed in order to determine the behavior expected of a DDR in order to realize it. These expected behaviors are captured as high-level requirements, which when normalized across all use cases, lead to a discrete set of DDR requirements.
