The other specifications are for SVG Referenced Parameter Variables: Part 1: Primer and Part 2: Language. The Referenced Parameter Variables specification provides a declarative way to incorporate parameter values into SVG content. Often, users may wish to create a single resource, and reuse it several times with specified variations, and this specification provides a means to do so without the use of script.

2009-04-23: The Cascading Style Sheets (CSS) Working Group invites implementation of the Candidate Recommendation of Media Queries. HTML4 and CSS2 currently support media-dependent style sheets tailored for different media types. For example, a document may use sans-serif fonts when displayed on a screen and serif fonts when printed. ‘screen’ and ‘print’ are two media types that have been defined. Media Queries extend the functionality of media types by allowing presentations to be tailored more precisely to device characteristics. Learn more about the Style Activity. (Permalink)
2009-04-23: The Cascading Style Sheets (CSS) Working Group updated the Candidate Recommendation of Cascading Style Sheets Level 2 Revision 1 (CSS 2.1) Specification. CSS 2.1 is a style sheet language that allows authors and users to attach style (e.g., fonts and spacing) to structured documents (e.g., HTML documents and XML applications). CSS 2.1 corrects a few errors in CSS2 (the most important being a new definition of the height/width of absolutely positioned elements, more influence for HTML's "style" attribute and a new calculation of the 'clip' property), and adds a few highly requested features which have already been widely implemented. But most of all CSS 2.1 represents a "snapshot" of CSS usage: it consists of all CSS features that are implemented interoperably. This draft incorporates errata resulting from implementation experience since the previous publication. Learn more about the Style Activity. (Permalink)

For descriptions and links to all the documents, see the OWL 2 Documentation Roadmap. This is a "Last Call" for the technical materials and is an opportunity for the community to confirm that these documents satisfy requirements for an ontology language. This is a second Last Call for six of the documents, but because the changes since the first Last Call are limited in scope, the review period lasts only 21 days. For an introduction to OWL 2, see the four instructional documents: an overview, primer, list of new features, and quick reference. Learn more about the Semantic Web. (Permalink)
2009-04-16: The Technical Architecture Group has published the First Public Working Draft of Usage Patterns For Client-Side URI parameters. The goal of this draft TAG finding is to initially collect the various usage scenarios that are leading to innovative uses of client-side URI parameters, along with the solutions that have been developed by the Web community. As highly interactive applications get built using Web parts (HTML, CSS and JavaScript component resources) that are themselves Web addressable, there is an increasing need for encoding interaction state as part of the URI. The Web is beginning to discover and codify design patterns based on fragment identifiers for many of these use cases. Learn more about the Technical Architecture Group. (Permalink)

2009-02-02: The XML Schema Working Group has published the Last Call Working Drafts of W3C XML Schema Definition Language (XSD) 1.1 Part 1: Structures and Part 2: Datatypes. This former specifies the XML Schema Definition Language, which offers facilities for describing the structure and constraining the contents of XML documents, including those which exploit the XML Namespace facility. The schema language, which is itself represented in an XML vocabulary and uses namespaces, substantially reconstructs and considerably extends the capabilities found in XML document type definitions (DTDs). The latter defines facilities for defining datatypes to be used in XML Schemas as well as other XML specifications. The datatype language, which is itself represented in XML, provides a superset of the capabilities found in XML document type definitions (DTDs) for specifying datatypes on elements and attributes. Comments are welcome through 20 February. Learn more about the Extensible Markup Language (XML) Activity. (Permalink)
2009-02-02: The WebCGM Working Group has published a Working Draft of WebCGM 2.1. Computer Graphics Metafile (CGM) is an ISO standard, defined by ISO/IEC 8632:1999, for the interchange of 2D vector and mixed vector/raster graphics. WebCGM is a profile of CGM, which adds Web linking and is optimized for Web applications in technical illustration, electronic documentation, geophysical data visualization, and similar fields. First published (1.0) in 1999, WebCGM unifies potentially diverse approaches to CGM utilization in Web document applications. It therefore represents a significant interoperability agreement amongst major users and implementers of the ISO CGM standard. Learn more about the Graphics Activity. (Permalink)

2009-01-28: The XML Core Working Group has published the W3C Recommendation of XML Base (Second Edition). This document describes a mechanism for providing base URI services to XLink, but as a modular specification so that other XML applications benefiting from additional control over relative URIs but not built upon XLink can also make use of it. The syntax consists of a single XML attribute named xml:base. The functionality is similar to the base element in HTML. This document is part of W3C's ongoing work to maintain the core XML technologies. Learn more about the Extensible Markup Language (XML) Activity. (Permalink)
2009-01-28: The XHTML2 Working Group has published the Group Note of XHTML Media Types - Second Edition. Many people want to use XHTML to author their Web pages, but are confused about the best ways to deliver those pages in such a way that they will be processed correctly by various user agents. This Note contains suggestions about how to format XHTML to ensure it is maximally portable, and how to deliver XHTML to various user agents - even those that do not yet support XHTML natively. This document is intended to be used by document authors who want to use XHTML today, but want to be confident that their XHTML content is going to work in the greatest number of environments.

2009-01-20: The Media Annotations Working Group has published the First Public Working Draft of Use Cases and Requirements for Ontology and API for Media Object 1.0. This document specifies use cases and requirements as an input for the development of the "Ontology for Media Object 1.0" and the "API for Media Object 1.0". The ontology will be a simple ontology to support cross-community data integration of information related to media objects on the Web. The API will provide read access and potentially write access to media objects, relying on the definitions from the ontology. Learn more about the Video in the Web Activity. (Permalink)
2009-01-16: The XHTML2 Working Group invites implementation of the Candidate Recommendation of CURIE Syntax 1.0. This document defines a generic, abbreviated syntax for expressing URIs. This syntax is intended to be used as a common element by language designers. The intended audience for this document is Language designers, not the users of those Languages. Track implementations in an ongoing implementation report and learn more about the HTML Activity. (Permalink)
