Efficient XML Interchange (EXI) Drafts: Format, Best Practices, Primer

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.

Device Description Repository Core Vocabulary

2007-12-21: The Mobile Web Initiative Device Description Working Group has published the First Public Working Draft of Device Description Repository Core Vocabulary. This document describes the Device Description Repository Core Vocabulary for Content Adaptation, that is, the properties that are considered essential for adaptation of content in the mobile Web. Its intended use is to define a baseline vocabulary for implementations of the Device Description Repository (DDR). Learn more about the Mobile Web Initiative Activity. (Permalink)

Last Call: Selectors API; New Draft of DOM Level 3 Events

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.

W3C Invites Implementations of DCCI 1.0 (Candidate Recommendation); first draft of Delivery Context Ontology available

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.

Last Call: SVG Print 1.2 Language, Primer

2007-12-21: The SVG Working Group has published Last Call Working Drafts of SVG Print 1.2, Part 2: Language and SVG Print 1.2, Part 1: Primer. The former defines features of the Scalable Vector Graphics (SVG) Language that are specifically for printing environments; the latter provides guidelines on how to use the print specification with SVG 1.2 Tiny and SVG 1.2 Full modules. Comments on both specifications are welcome through 08 February. Learn more about the Graphics Activity. (Permalink)

Note: Device Description Repository Requirements 1.0

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.

Cool URIs for the Semantic Web (First Public Draft)

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)
